Water purification system for apartments. The best household water purification system in an apartment. Mesh with auto-rinsing
When choosing any equipment for housing, we always ask ourselves whether there are special organized rules. For example, when purchasing water filters, you definitely need to know their structural and functional features. Each individual cleaner for rough drinking water has its own characteristics that are suitable for use in specific conditions. What these conditions are and what the choice is based on we will consider in our article today.
The question seems to be quite familiar, but many residents apartment buildings after all, they are asked quite often. We bring to the reader's attention comprehensive instructions, which will serve as an excellent assistant when planning to install water filters. Everything is done in several elementary steps.
Attention! When installing a filter for drinking water, take care of the preliminary cleaning, especially if the conditions of your central pipeline do not allow the water to be used unchanged.
What kind of filter is needed to enjoy clean water?
Jug cleaner is perhaps one of the most common and easiest to use. He doesn't require special installation and control, so apartment owners prefer this option, leaving others. It is important to note that such a purifier is only suitable if your water supply is relatively clean. bad water. The filter jug makes rough water softer, freeing it from metal ions and other unfavorable impurities, making it drinkable.
A flow-through version in the form of a faucet attachment is suitable for purifying chlorine in water. However, it is inconvenient to use such a device constantly, as the water pressure decreases. Types of water filters for under the sink will help purify rough water, displace salts and excess minerals from it, depending on what cartridges the water purifier will operate on. This design does not require a liquid storage tank or additional parts.
Pre-filters are used for installation directly from the apartment riser in front of the meter and are intended for coarse filtration. A similar device is used as a flow-through water purifier. Such filters are required for mechanical removal of metal compounds. If the space in the apartment where the water is too hard allows, it is recommended to install reverse osmosis. This installation is a purification tank with several cartridges, allowing for combined water purification in several stages behind the meter.
A flow-through oblique coarse filter is usually located at pipe connections and often plays the role of a fitting. Inside this connector there is a fine mesh that traps debris and other particles entering the water supply. In addition to such a device, additional filtration will be required. Since water from such filtration does not become drinkable. It does not require an additional tank. Look at the photo to see how such a filter is installed.
Installation of reverse osmosis and under-sink purifier: step-by-step instructions
After choosing the right water purifier, you should take care of its installation and insertion into the pipeline. As you can see, the ideal solution in our case was the purchase of reverse osmosis and an additional water purifier under the sink.
Important! The installation of reverse osmosis must be carried out in sufficient space and hidden from view.
Attention! Under no circumstances use pre-coarse purified water for drinking or other household needs. Before use, the tank and all parts of the system as a whole must be thoroughly flushed.
Liquid flowing in a centralized water supply can only very conditionally be considered suitable for use for technical purposes - for laundry, washing dishes, etc. With a very big stretch, it can be used for cooking, but you can’t drink it without boiling it at all. To bring it to normal, it is necessary to use different types of filters to purify water. There are inexpensive installations, but they usually have low productivity and average cleaning quality, and there are expensive systems that can give ideal results.
The situation is no better with water supply from a well or borehole. There is still a high probability of bacterial infection, so the cleansing should be even better. In general, you need to take the sample for analysis, and then, based on the results, select the required types of filters for water purification. In private homes, this is usually a multi-stage system, which results in drinking-quality water.
Cleansing from mechanical impurities
The water that flows in our water supply contains grains of sand, fragments of rust, metal, windings, etc. These impurities are called mechanical. Their presence has a bad effect on the durability of shut-off valves (taps, valves, etc.) and household appliances. That’s why in apartments and private houses they install filters at the entrance to remove them. There are few types of filters for purifying water from mechanical impurities. This is with mesh and discs as filter elements.
The filter element in mechanical filters is a mesh. Based on cell size, these filters are divided into coarse (300–500 microns) and fine cleaning devices (larger than 100 microns). They can stand in a cascade - first for coarse cleaning (mud collector), then for fine cleaning. Often a coarse filter is placed at the entrance to the pipeline, and devices with a finer mesh are placed in front household device, because different equipment may require to varying degrees water purification.
Depending on the orientation of the flask in which the filter element is installed, they can be straight or oblique. Oblique ones create less hydraulic resistance, which is why they are most often installed. When installing, you must observe the direction of flow, it is indicated on the body by an arrow.
Mechanical filter
There are two types of mechanical filters - with and without auto-rinsing. Devices without auto-flushing are small in size; their inlet/outlet diameters are selected according to the size of the pipe in which they are installed. Case material - stainless steel or brass, threaded connections - different (external or internal thread select as needed). The cost of this type of mechanical filters is low - around hundreds of rubles, although branded ones can cost much more.
Mechanical filters without backwashing: straight and oblique
Since the grids become clogged and need to be cleaned periodically, the lower part of the flask is removable. If necessary, unscrew it, remove it and wash the mesh, then return everything back (all work is carried out by first turning off the water).
Mesh with auto-rinsing
A mechanical filter with auto-washing (self-washing) has a pipe and a tap in the lower part of the flask with a filter element. The pipe is led into the sewer using a hose or piece of pipe. If you need to rinse such a filter, simply open the tap. Water under pressure washes the contents into the sewer, the tap closes, and you can continue using it.
This video mechanical filter for water often contains a pressure gauge. It determines whether the mesh is clogged or not. The pressure has dropped - it's time to clean the filter. If the device bulb is transparent, there may not be a pressure gauge - you can determine by appearance mesh or flask walls. In this segment, oblique water filters are rare, but they do exist.
A pressure reducing valve can be built into the housing to neutralize pressure differences. There are models with the ability to install an automatic flushing unit.
Tying this type of mechanical filters is a little more complicated - it requires an outlet to the sewer, but there are also models with different types of threads so that you can use as few adapters as possible.
Connection types
Mechanical cleaning filters can be either coupling or flanged. Flanged - this is usually main equipment for water pipelines with high pressure and diameters. Can be used to install water supply for a private home.
Disc (ring) filters
This type of equipment is less common, although it is less prone to silting and has large area filtration, can retain particles of different sizes.
The filter element is a set of polymer disks, on the surface of which scratches of varying depths are applied. When assembled, the disks are pressed tightly against each other, water passes through the hollows in the disks, and particles of larger diameter settle on them. The movement of water is spiral-shaped, so that suspended matter is removed efficiently.
When the water purification filter becomes clogged, the discs are removed from the housing, pulled apart and washed. After that they put it in place. The discs must be replaced periodically; the service life of the filter element depends on the amount of contamination and the quality of the discs themselves. There are models with automatic flushing.
Mounted into a pipe break, the bulb can be directed up or down (see installation instructions).
Inexpensive types of filters for purifying water for drinking purposes
Water purified from mechanical impurities can be used for domestic needs and supplied to household appliances, but it is only suitable for drinking or cooking - after boiling. In order to drink it without boiling, fine filters are needed that retain a significant part of the substances dissolved in the water and disinfect it. Let's look at how to make tap water drinkable and the types of water purification filters that can be used.
Filter jug
The simplest, but not very productive way to make tap water drinkable is to pass it through a filter jug. Cleaning occurs in a replaceable cartridge through which water passes. A good cartridge contains the following filter media:
- polypropylene fibers for sedimentation of residual mechanical impurities;
- activated carbon with additives to remove microorganisms and chlorine compounds;
- ion exchange resin for removing manganese and calcium salts, radionuclides, iron compounds, heavy metals;
- porous activated carbon for water clarification, sedimentation of organic matter.
Filter jug - simple, cheap
Filter jugs differ in the composition of the cartridge, its resource (how much water can be purified) and volume. The smallest models of tabletop filters can purify 1.5-1.6 liters of water at a time, the largest - about 4 liters. Just keep in mind that in the column “filter volume” the volume of the bowl is indicated, the useful volume (the amount of purified water) is much less - about half.
| Name | Bowl volume | Cleaning module resource | Degree of purification | Additional devices | Price |
|---|---|---|---|---|---|
| AQUAPHOR Art "Ice Age" | 3.8 liters | 300 l | 4-6$ | ||
| AQUAPHOR Prestige | 2.8 l | 300 l | Slightly reduces water hardness, removes mechanical and organic impurities, active chlorine, heavy metals | Resource indicator | 5-6$ |
| AQUAPHOR Premium "Dachny" | 3.8 l | 300 l | Reduces water hardness, removes mechanical and organic impurities, active chlorine, heavy metals | Large funnel - 1.7 l | 8-10$ |
| Filter jug Barrier Extra | 2.5 l | 350 l | 5-6$ | ||
| Filter jug Barrier Grand Neo | 4.2 l | 350 l | Depending on the filter type | Cassettes for different types water they go to + to the cost of the jug | 8-10$ |
| Filter jug Barrier Smart | 3.3 l | 350 l | Depending on the filter type | Cassettes for different types of water they come with + cost + mechanical resource indicator | 9-11$ |
| Geyser Aquarius filter jug | 3.7 l | 300 l | For hard water with bacterial treatment | Cartridge replacement indicator | 9-11$ |
| Filter jug Geyser Hercules | 4 l | 300 l | From heavy metals, iron, organic compounds, chlorine | Receiving funnel 2 l | 7-10$ |
Filter nozzle for faucet
A very compact filter for running tap water that fits onto the tap. Cleansing speed - from 200 ml/min to 6 l/min. The degree of purification depends on the composition of the filter part, but is usually not much different from jug filters.
According to the method of operation, there are two types of filters on the faucet - some are put on immediately before use, others have the ability to switch to the “without cleaning” mode. The second option is definitely more convenient, but the switches often break. As a temporary measure, this is an excellent solution, but “permanently” it is better to choose another device.
| Name | Performance | Cassette resource | What cleanses | Country of origin | Price |
|---|---|---|---|---|---|
| Defort DWF-600 | up to 20 l/hour | 3000-5000 l | China | 2$ | |
| Defort DWF-500 | up to 20 l/hour | 3000-5000 l or 6 months | organic substances, pesticides, heavy metals, chlorine and radioactive elements | China | 2$ |
| Aquaphor Modern-1 | 1-1.2 l/min | 40000 l | from active chlorine, lead, cadmium, phenols, benzenes, pesticides | Russia | 13-15$ |

| Sorbent RODNIK-ZM | 2 l/min | 3600 l | free chlorine removal, iron removal | 8-10$ |
Filters under/on the sink - a way to get a large amount of drinking water
For greater productivity and better water purification, filters are used that are installed under or on the sink; they can also be mounted on the wall.
There are two types of such systems - cartridge and reverse osmosis systems. Cartridge ones are cheaper, and this is their advantage, but the disadvantage is that you need to monitor the condition of the filter element and change it on time, otherwise all the accumulated dirt goes into the water.
Reverse osmosis systems are more technologically advanced equipment that have a much higher cost, but the quality of cleaning and productivity are much higher. These water treatment plants use a multi-layer membrane, each layer of which traps a specific type of contaminant.
Cartridge
In cartridge filters, the quality of cleaning depends on the number of cleaning stages - individual filter elements that “catch” a certain type of contaminant. There are single-stage systems, there are two, three and even four-stage filters.
Single-stage ones use universal inserts that have a multilayer structure. They are inexpensive, but it is difficult to predict whether you will be satisfied with the degree of cleaning. Composition of water in different regions is very different and it would be advisable to select/replace filters as needed. And so, we have to hope for the versatility of the liner.
In multi-stage cartridge filters, the housing consists of several flasks, each of which has a separate/special filter element that removes certain contaminants. The flasks are connected in series using overflows, flowing from one flask to another, the water is purified. In this case, it is possible to select the types of filters for water purification specifically for your analysis, which will undoubtedly improve the quality of purification.
| Cartridge filter name | Type | Number of cleaning stages | For what kind of water? | Cartridge life | Performance | Price |
|---|---|---|---|---|---|---|
| BWT Woda-Pure | Household washable | 1 cartridge + membrane | medium hard | 10,000 l or 6 months | 1.5-3 l/min | 70$ |
| Raifil PU897 BK1 PR (Big Blue 10”) | Trunk | 1 | cold tap water | 26$ | ||
| Geyser Lux | Under the sink | 3 | soft/medium/hard/ferruginous | 7000 l | 3 l/min | 70-85$ |
| GEYSER GEYSER-3 BIO | Under the sink | 3 + protection against viruses and bacteria | soft/hard/very hard/ironous | 7000 l | 3 l/min | 110-125$ |
| Geyser-1 Euro | Desktop option | 1 | normal/soft/hard | 7000 l | 1.5 l/min | 32-35$ |
| Pentek Slim Line 10 | Trunk | 1 | 19 l/min | 20$ | ||
| Expert M200 | Under the sink | 3 | normal/soft | 6,000 - 10,000 l depending on the cartridge | 1-2 l/min | 60-65$ |

| AQUAFILTER FP3-HJ-K1 | Under the sink | 4 + protection against bacteria and viruses | For cold water | 3 l/min | 60-90$ | |
| Barrier Expert Hard | Under the sink | 3 | for hard water | 10,000 l or 1 year | 2 l/min | 55-60 $ |
| Atoll D-31 (Patriot) | Under the sink | 3 | highly chlorinated water | 3.8 l/min | 67$ |
Tabletop cartridge filters for running water
Most inexpensive option cartridge filters are installed next to the sink. These are miniature models that are small in size. Can be one or two stage, on the body there is small sizes tap. The filter is connected with hoses to a special outlet of the mixer; it can be connected directly to the water supply.
Trunk
These are usually single-stage cartridge filter flasks, which are placed after the mechanical filter. They remove a significant amount of impurities, making the water suitable for drinking and protecting household appliances from the formation of scale and other deposits. Their disadvantage is the need to change filter elements.
For ease of monitoring the condition and degree of contamination, the flask is made transparent. If visible contamination occurs, replace the cartridge with another one. In some models, it is possible to independently restore the functionality of the cleaning element - it is washed under running water. In other models this is prohibited, so read the instructions carefully.
Multistage filters
Different from those described above a large number flask cases, each of which contains a cartridge that removes various types pollution. The more stages of purification, the purer the resulting water. The composition of the filter elements must be selected for the specific composition of the water (read carefully technical specifications and description).
These installations can also be installed on the main line, or they can be placed under the sink and receive high-quality drinking water.
Reverse Osmosis
The most advanced water purification technology today is reverse osmosis. It uses multilayer membranes that allow only water and oxygen molecules to pass through, preventing even the smallest contaminants from passing through. The water obtained is practically free of salts, which is also not good. This is precisely the disadvantage of reverse osmosis systems. To neutralize it, the plants are equipped with mineralizers that add the necessary minerals.
| Name | Number of cleaning stages | Lifetime/replacement frequency | Filtration speed | Notes | Price |
|---|---|---|---|---|---|
| Geyser Prestige 2 | 6 | 1 time per year | 0.15 l/min | Purified water storage tank 7.6 l | 70-85$ |
| Atoll A-450 (Patriot) | 6 | prefilters - 6 months, membrane -24-30 months, carbon postfilter - 6 months. | 120 l/day | There is an external tank | 115-130$ |
| Barrier Profi Osmo 100 | 6 | 1 step - from 3 to 6 months, 2 steps - every 5 - 6 months, 3 steps - from 3 to 6 months, 4 steps - from 12 to 18 months (up to 5000 liters), 5 steps - every 12 months | 12 l/hour | There is an external tank | 95-120$ |
| Aquaphor DWM 101S Morion (with mineralizer) | 6 | prefilters - 3-4 months, membrane - 18-24 months, post-filter mineralizer - 12 months. | 7.8 l/hour | External tank + mineralizer | 120-135$ |
| Barrier K-OSMOS (K-OSMOS) | 4 | 5000 l (no more than a year) | 200 l/day | External tank | 120-150$ |
| Atoll A-450 STD Compact | 5 | prefilters - 6 months, membrane - 24-30 months, carbon postfilter - 6 months. | 120 l/day | External tank | 150$ |
The disadvantages of this system include their low productivity - only one glass or so can flow per minute clean water. It is clear that such a speed causes inconvenience, so that it is felt less, manufacturers complete the installations with tanks for purified water, to which taps are already connected.
Filters for purifying water from dissolved substances
In addition to mechanical impurities, tap water also contains a decent portion of the periodic table: iron, mercury, manganese, potassium, calcium (hardness salts from which scale is formed), etc. All of them can be removed, but different filters are needed for this.
To make water potable, different types of filters are used to purify water.
To remove iron
Most often, water from wells or wells contains large number gland. It gives the water a reddish tint and a specific taste, is deposited on the walls of plumbing fixtures, and clogs shut-off valves, therefore it is advisable to remove it. It makes sense to do this if the amount of iron exceeds 2 mg/l.
Divalent iron dissolved in water can be removed from the water using a catalytic filter. This is a large cylinder into which catalysts are poured, the work is controlled by a small processor, that is, this equipment requires a power supply.
The backfill located in the catalytic filter greatly accelerates the process of oxidation of divalent iron and its precipitation. Depending on the backfill, impurities of manganese, chlorine, and other substances dissolved in water may also be removed, and mechanical particles will also settle to the bottom during the cleaning process. Removal of accumulated deposits occurs according to a given schedule, usually at night. The backfill is washed under the pressure of water, everything is drained into the sewer, and the water supply is stopped during washing. Catalytic filters are complex and expensive equipment, but they are the most durable available.
Another way to remove iron and water is aeration. Water is supplied in the form of a fine suspension (through nozzles) into a cylinder with a forced air pump. The iron in it reacts with oxygen in the air and its oxides are filtered out at the outlet. There are two types of filters for purifying water of this type - pressure and non-pressure. For more active oxidation, an oxidizing agent—hydrogen peroxide or sodium hypochlorite—can be supplied to these installations. In this case, biological purification of water is also carried out - from microbes and bacteria.
Purification of water from hardness salts
To soften water, filters with ion exchange resins are used. In the process of interaction with water, replacement occurs harmful impurities to neutral or beneficial (increasing the amount of iodine and fluorine).
Externally, this equipment is a tank partially filled with ion-exchange material. Paired with it is a second similar regenerator tank filled with a highly concentrated salt solution (a special one is sold in tablets, high degree cleaning).
The advantages of filters for water purification of this type are high performance, low level noise during operation, rare replacement of backfill (it lasts for 5-7 years). For water softening, ion exchange filters are the most best choice. Disadvantages - the need to use a regeneration tank with concentrated saline solution. To obtain drinking water, you need to install an activated carbon filter.
Tap water almost never meets the requirements for purity - impurities appear in it one way or another, as a result of which the taste, smell and even transparency change. It is clear that you should not drink water directly from the tap. You can solve the problem by installing a main filter for water purification in the apartment. This device is mounted directly into the pipeline and allows you to purify the entire volume of passing water.
Main filters for cold or hot water are used for the following needs:
- Water purification. This is very important, because not everyone can live above a deep well, and drinking water comes to houses, most likely, from the nearest reservoir, river or lake. At the same time, city treatment stations often do not remove carcinogens and heavy metals from water, but only chlorinate, while a number of bacteria resistant to chlorine may remain in the liquid.
- Improving the taste of water. Chlorine, rusty metal, hydrogen sulfide - water with completely unexpected tastes can flow from the tap. Naturally, it changes the quality of food. And purified water allows you to prepare truly delicious dishes.
- Softening water to reduce its impact on skin and hair. After all, contaminated water spoils hair and skin, leads to the appearance of wrinkles, rashes, and destruction of the hair structure. And purified water will not allow all these manifestations to form.
- Maintaining the functionality of equipment and plumbing fixtures. If solid particles and dirt are not removed, then on boilers, dishwashers and washing machines, scale appears in electric kettles.
Different types of devices and how they work
Main filters for water purification in the apartment and in country house classified into:
The main filter for water purification most often works in conjunction with additional accessories. Thus, a softener is installed along with a coarse filter, which allows you to normalize the chemical composition of the liquid and prevent the formation of scale in equipment. Reagent-free filters with permanent magnets, the action of which causes salts dissolved in water to precipitate without causing harm to plumbing and other appliances.
AND Only after the coarse cleaning system are fine cleaning devices installed- in this case they will be less susceptible to contamination and the cartridges will have to be changed less often.
Information about this is in a separate article on the site. You will also find a video example there.
Read about the room in another material. Describes how to troubleshoot basic problems.
You can also purchase grain loading equipment. It is a main filter for complex cleaning, allowing to eliminate both chemical and biological contaminants. Externally, it is a large cylinder, the productivity of which ranges from 16-400 liters per minute. Such main filters for water in an apartment or in private house They are both water softeners and deep cleaning filters. The downside is their large size.
Rules for choosing a suitable filter model
So, in-line water filter - how to choose for cleaning? Please note that in ordinary apartments usually passes two lines - from cold and from hot water . If we are talking about individual heating systems, then they require devices for purifying cold water.
Important: The main hot water filter is made of materials that are resistant to prolonged exposure high temperatures. It can also be used on cold water lines, but not vice versa.
To choose main filters for cold or hot water, you must consider:
The mesh filters used are multi-layered and fixed in metal pipe. With its help, water is purified from all large particles (sand or scale), the size of which exceeds 50 microns. It is better to choose a main water filter with flushing - it is able to catch more contaminants. When choosing a mesh filter, you must specify the pipe diameter, on which the fastening will be made, and in accordance with this value, purchase the device.
As for cartridge devices, a mainline mechanical water purification filter is a structure consisting of a flask, a lid and a replaceable cartridge. They are able to catch any small particles - accordingly, the finer the degree of filtration, the more transparent and tastier the output water will be.
The cartridge for main filters for water purification should be regularly change and purchase depending on needs:
- BA - to normalize the amount of iron.
- BS - for water softening.
- With activated carbon - for cleaning from chlorine.
- With polyphosphate loading - eliminates lime deposits and protects devices from scale.
The main filter is installed directly into the water main. It is also advisable to install shut-off valves in the area where water is supplied and drained from the filtering device. ball valves and bypass. The installation location of the cartridge filter must be freely accessible, since the cartridges will have to be replaced regularly. We eliminate the most common faults.
Brief overview of filter manufacturers
Among the popular companies producing high-quality main filters, it is worth noting Honeywell and Aquaphor, New Water and Geyser.
Thus, the Aquaphor company produces wide range cartridge main filters - for drinking water, for household appliances (for washing machines or dishwashers), for showers. You can select devices designed for operation with cold and hot water, eliminating chemical compounds or only insoluble impurities such as sand or rust.
The German brand Honeywell offers devices of unique quality, designed for ten times the operating pressure in the network. Here you can select elements for coarse or fine cleaning, with the filter element being metal mesh, enclosed in a highly reliable flask.
Company products New Water characterized by accessibility and high quality. The range includes main filters with a separate tap, and the degree of cleaning can be adjusted by installing certain cartridges.
And Geyser filters are high-tech scientific developments, thanks to which filter elements based on ion-exchange polymer were created.
The water purification system for an apartment must be modern, environmentally friendly, ergonomic and efficient. It includes a set of various filters with additional equipment(hoses and containers for supplying and discharging clean and dirty water). The water purification system in the apartment should be minimal overall dimensions. That is, only compact or mobile ones are used, which are easy to fit under the sink or move.
The main connecting elements are fittings, plastic lines, and taps. Manufacturers usually supply components with their equipment. Thanks to universal adapters, filtration systems are quickly and easily installed.
Types of cleaning systems
They produce several types of water filtration systems for apartments:
- sorption;
- membrane;
- ion exchange.
A private house has a great advantage for installing a cleaning system: you can select an isolated room or space. The apartment is limited in area, all objects in it are in contact with its residents.
Today, many supporters of environmentally friendly products are beginning to abandon ion exchange filters. In them, the filter mass is restored in regenerating solutions. Membrane systems are gaining popularity.
Sorption filters with replaceable modules are also often used, which are easy to replace and do not need to be restored.
Basic requirements for water purification systems for apartments
As with any water filtration system, you should chemical analysis. Apartment buildings supplies water to the central water supply system. People don't need systems pre-cleaning, if the water comes from modern communications. Filtering devices in the apartment should work to remove chlorine and hardness salts.
In confined spaces, filters with storage tanks for storing filtrate are rarely used. A mobile and smaller version of such systems is a filter jug, which supplies water to a family of 2-3 people.
Often, drinking water purification systems for apartments will be hindered by non-traditional methods of water preparation: structuring, magnetic field, ultrasound. But many residents of megacities choose a conservative approach to water purification, which have proven themselves over many years of use in softening and removing chlorine, and comply with norms and standards.
Choosing a water purification system for an apartment
Each area has an individual water composition. Therefore, there are no exact guidelines for choosing a water filtration system. But if you firmly decide to use purified water, then you need to start with zero level. It is necessary to determine exactly what the water should be purified from. This can be done in a laboratory or independently at home.
Let us warn you right away: one filter will not be enough. Drinking water requires a more careful approach than technical water.
Drinking water filters
In the apartment optimal options There will be a multi-stage system, a faucet attachment or a filter jug.
Filter jug
At first sight budget option It looks like a filter jug. However, it is effective if the quality of tap water is acceptable. The filter jug allows you to:
- reduce chlorine concentration;
- reduce the amount of copper and iron;
- reduce water hardness;
- remove mechanical impurities.
There are significant differences between filter jugs from different manufacturers. Large enterprises try to specialize their cartridges for different types of water. It is better to give preference to products from well-known brands at a slightly higher cost. Cheap jug filters can only perform mechanical cleaning or may not be effective at all.
The advantages of filters of this type include:
- low cost;
- easy to use;
- does not require installation.
The disadvantages are:
- short cartridge life;
- cartridges cannot be restored;
- Not high efficiency cleaning.
Faucet attachment
The method and effectiveness of faucet attachments are similar to jug filters. they remove chlorine compounds and perform mechanical cleaning. Additionally, specialization may be provided. If the filter mass is an ion exchange resin, then heavy metals, hardness salts, iron ions, and aluminum are removed. When using activated carbon Most types of organic matter, bacteria, and phenol are removed.
How is a nozzle better than a jug? It all depends on individual preferences. Sometimes it is possible to regenerate the ion exchange resin, which is not typical for cartridges from filter jugs.
Advantages of the faucet attachment:
- easy installation;
- minimum system dimensions at good quality cleaning;
- convenient to use.
The disadvantages are the same as those of jug filters.
Multistage systems
Multi-stage systems are used for serious water problems. Many of them are equipped with a reverse osmosis membrane. But even in its absence, the efficiency is quite high.
Advantages of multi-stage systems:
- greater efficiency;
- solves almost all water problems.
Flaws:
- high cost;
- requires a certain space;
- complex installation;
- slow work;
- reverse osmosis requires a large volume of water (for 1 liter of clean water you need 5 liters of “waste”);
- expensive consumables.
Many people consider deep cleaning to be a disadvantage: essential microelements are removed. But you can always additionally provide a mineralizer or resort to other methods of increasing the mineralization of water.
Process water purification systems
Firstly, the water must undergo rough cleaning before being supplied to the apartment. This is needed to protect plumbing and household appliances. The service life is also extended consumables in a drinking water purification system.
Washing and dishwashers, in which water is heated, require separate water softening filters. They can be installed in front of the device.
But with increased rigidity, it is better to solve the problem comprehensively. After all, hair and skin suffer from hardness salts. The minimum cost will be a filter nozzle for the shower.
High performance ion exchange softeners are not suitable for small apartments, as they require a lot of space. Experts recommend using a magnetic softener.
The described filters are installed in a cold water pipeline. Hot water also requires cleaning.
Water purification is a complex task. To solve it, an individual approach to creating a water purification system from different types filters.
In systems centralized water supply cleaning is performed by chlorinating the liquid. As a result, disinfection is carried out - the removal of pathogenic microflora. But chlorinated water is dangerous to drink; it also damages hair and causes dry skin. Individual filters ensure safe cleaning for health. Their choice depends on the purpose and operating conditions.
Types of filters for water purification
Jugs are inexpensive, compact, easy-to-use models. Used at home and in offices. Cartridges must be replaced every 2–4 months. The equipment eliminates rust, chlorine and other impurities.
Drinking water filters that are installed under sinks are massive, bulky systems. Quite different complex installation and high cost, but they remove not only chlorine and rust, but also dangerous bacteria, and prevent the appearance of scale. The equipment is only suitable for buildings with a centralized water supply system.

How to choose a water filter?
The quality of cleaning largely depends on chemical composition liquid that is supplied to a specific object.
You should also consider design features devices:
- efficiency;
- operating principle;
- purpose - for industrial or residential facilities;

At the preliminary stage, specialists collect liquid and carry out analysis in the laboratory. Depending on the obtained indicators, optimal filtration layers are selected. As a result, the equipment effectively eliminates existing contaminants.
Some types of water purifiers are built into the pipeline - installation is carried out only by specialists. Tabletop models and jugs do not require installation work, in this case only delivery is made.
Water filters need to regularly replace cartridges. Its frequency is affected design features models, intensity of use and other individual parameters. In most devices household cleaning water, replacing cartridges is not difficult and is carried out by the user.
