Water purification filter for a summer residence: tips for choosing + an overview of the best brands

Under sink cleaners with reverse osmosis membranes

The need to install expensive reverse osmosis systems arises in regions with heavily polluted water.

When choosing this option, cold water passes successively through the steps:

• mechanical,
• sorption
• ion-exchange cleaning (otherwise thin membranes would quickly fail)
• are fed to nanofiltration or reverse osmosis membranes that capture almost all foreign impurities.
• after that, the water passes through the carbon post-filter and is supplied to the consumer.

The performance of reverse osmosis systems largely depends on the operating pressure at the inlet, optimal results are achieved by maintaining this parameter within 3-7 atm. (the exact range depends on the modification and is specified by the manufacturer).

Interesting! Due to the low throughput of the membranes and the need for their flushing, systems for washing this type must be equipped with storage tanks and outlets for draining (at least 2.5 liters per 1 liter of clean water goes to drains). Other indicators of the most popular reverse osmosis systems are presented below.

Barrier Profi OSMO 100

This system is positively evaluated by more than 85% of users with an emphasis on ease of installation and high quality filtration.

In addition to the high cost of consumables (from 700 rubles when buying replaceable modules for stages 1-3, from 2900 - 4 and 5), the features of this system that are taken into account include:

1. opacity of flasks,
2. consumption of at least 2-2.5 liters of water per drain when cleaning 1 liter of water with membranes
3. need for pressure control.

Geyser Prestige

Ergonomic system with a pre-filter, a membrane that retains up to 99.7% of impurities and a carbon post-filter made of coconut shell.

When using this model, it should be remembered that its individual filtration elements have different service lives (up to 20,000 liters for a polypropylene mechanical pre-filter, 7,000 liters for 2 and 3 stages of sorption cleaning, 1.5-2 years and 50 gallons for a block with a membrane and no more than 1 year of service at the post-filter).

Over 80% of users consider this system convenient and effective.

Operational shortcomings largely coincide with the previous model (need for space, part of the water drained, the high cost of cartridges).

Estimated costs for the purchase of the basic Geyser Prestige package are:

• 8800 rubles,
• for a complete replacement of cartridges - 3850 (1400 rubles for updating pre-filters, 2450 for a membrane and post-carbon).

Aquaphor DWM-101S

A lightweight reverse osmosis system that works even in cases of low inlet water pressure (from 2 to 6.5 atm). The service life of the individual stages of cleaning Aquaphor DWM-101S depends on their purpose and varies from 3 months for pre-filters to 2 years for expensive membranes.

The system enriches water with natural magnesium and calcium while significantly reducing the overall level of hardness and removes all harmful chemical impurities from it.

The demand for the system is confirmed by a large number of positive reviews, Aquaphor DWM-101S is inferior to analogues only in the volume of drain (at least 4 liters compared to 2-3 for competitor models). The total cost for the purchase of Aquaphor DWM-101S is 8900 rubles, for the replacement of filtration modules - 2900.

Scope of main filters

The high quality of water in the house is a guarantee of your health and long-term service of a number of household appliances such as washing machines, dishwashers, plumbing fixtures, etc. But if there are a lot of harmful impurities in the liquid flowing from the tap, then it makes no sense to talk about the quality of the water. Most often, residents of large cities face such problems.Water treatment plants operated by public utilities simply cannot purify water well enough to be safe. A special device that is installed individually in the apartment helps to solve the problem and purifies the water entering it through pipes from dangerous impurities. That's what main filters are for.

The main-type filter, unlike other types of filtering devices, is built directly into the water supply. These are hot and cold water pipes. And ideally, the filtering device should be both there and there. This is the entrance step to the plumbing system in the apartment.

The main filter installed in the apartment

What are the tasks of main filters?

• Purification of water from rust that enters the liquid during its flow through outdated, sometimes rusted pipes.
• Purification of water from sand, if the filter is installed in a private house, where wells are most often used as a source of water.
• Reducing the level of water mineralization and softening it.
• Improvement of water quality.
• Making water suitable for drinking.
• Protecting household appliances from the formation of lime deposits and extending their service life.
• Removal of pathogens from water.
• Improving the organoleptic properties of the liquid - taste, color and smell.

No. 2. Why is the main filter better than others?

The problem of polluted water is so massive that mankind has come up with a lot of different devices for cleaning it. We will not go into details, but among the most popular filtration systems today they use the following:

• pitcher-type filters and dispensaries do not belong to flow filters - a certain amount of water is poured into them, which after a while is cleaned by built-in cartridges. This solution is only suitable for water purification for drinking and cooking, since the volume of vessels, as a rule, does not exceed 3-4 liters;
• the filter nozzle on the tap allows you to purify water from large mechanical impurities, improve its organoleptic qualities. The filter is suitable if the water quality is satisfactory, meets the standards, but you just want to improve it a little. Such a filter is easy to install, you can even take it with you on trips, but it will not cope with serious pollution, has low performance and requires frequent replacement of cartridges;
• the “next to the sink” filter is also easy to install, connects to the water supply using a special adapter and provides an average level of purification, ridding the water of large contaminants and unpleasant odors;
• stationary filter "under the sink" is installed under the sink, allows you to purify water from mechanical impurities, chlorine, heavy metals, eliminate odors and tastes. This is a very popular system, it is easy to maintain, requires replacement of cartridges every 5-6 months, but the cost of its arrangement is higher than the previously listed options. This solution also has some drawbacks. The filter will not cope with the most serious contaminants, it has limitations in terms of performance and cannot be installed on pipes with hot water.

If any of the listed filters allows you to purify water to an acceptable quality, you are very lucky.But if you are not lucky, then you should not be upset, because there are flow-through main filters, which are actually a miniature water treatment station.

The main filter is built into the water supply system of an apartment or house, crashes into the water main and creates a serious barrier to the water entering the apartment, which, passing through the filter system, is cleaned of mechanical impurities, harmful elements and compounds. The filter can be put on hot and cold water, and since it will stand at the inlet, purified water will flow from all taps.

A flow-through main water filter is usually used in houses that have their own source of water supply (a well or a well), but recently a similar system has often been installed in apartment buildings where the water pipes are very worn out. Such filters allow you to solve several problems at once:

• water purification from harmful impurities, chlorine and microorganisms;
• improving the taste of water and getting rid of metallic and other tastes;
• softening, because hard water negatively affects the skin and hair, leads to the rapid wear of some household appliances;
• keeping plumbing fixtures in good condition. Conventional (non-main) filters purify water only at one point of consumption, and it runs through the rest of the pipes in the apartment silted and contaminated with particles of rust and other debris, which gradually leads to blockages and breakdowns. With the main filter, this problem disappears.

The main advantages of main filters include:

• high cleaning efficiency;
• high performance (the filter cleans 20-50 liters of water per minute);
• variability.Depending on what it is necessary to purify water from, various cartridges can be used;
• the ability to purify water for all water intake points with one filter;
• durability with proper use.

Among the shortcomings, we note only the complexity of installation - you will need the help of specialists. You can service the main filter yourself, but if a blockage occurs, you can hardly do without a professional. The cost of trunk systems, of course, is higher than that of simpler filters, but it is not sky-high.

Aquaphor OSMO 50

The development of a well-known Russian company will significantly improve the lives of those who are forced to use hard water. This reverse osmosis water purifier, in addition to the membrane, has 5 stages of purification, thanks to which it removes dangerous impurities, including bacteria, parasites and viruses, and also completely eliminates water hardness - the cause of scale and breakdown of many household appliances. And everything would be fine, but the residents of private houses with their own sewage system are unlikely to be happy that for 1 liter of purified water, another 6 liters will be needed, which will go into the drainage - this is a lot and will cost a pretty penny.

Filtration speed	0.13 l/min.
Water temperature	5-38°C
Line pressure	from 3.5 to 6.5 atm.
Storage tank capacity	10 l
Water purifier weight	10 kg

Cost: 6 090-11 826 rubles.

pros

• high-quality cleaning;
• large storage tank.

Minuses

• noisy;
• high water consumption.

Types of pre-filters

Representatives of the first group are equipped with a special mesh with small cells, where large fractions and harmful impurities are retained. The second type is equipped with a multi-layer cartridge that retains tiny contaminants.

Stainless steel mesh filters purify water using a metal mesh with a fine mesh structure. The sizes of these holes vary from 50 to 400 microns, which ensures the retention of most solid impurities. Rust and sand from the pipes remain on the filter devices without disturbing the performance of plumbing and other equipment in the house.

On sale are affordable self-cleaning mesh filters that are capable of self-cleaning without human assistance. The rest of the models need to dismantle the dirty mesh for washing.

Filter manufacturers also offer systems with a magnetic trap that attracts ferrous compounds, rust and other iron hydroxides found in water.

Cartridge pre-filters for hot and cold water are fixed on the surface, as they are large and take up a lot of space. Advanced designs are equipped with a transparent body, which allows users to follow the cleaning process and see how many different particles are in the pipeline fluid.

Inside the system there is a replaceable cartridge made of coal or pressed fiber, polypropylene thread or polyester. Depending on the elements used, the cleaning efficiency is determined. The throughput is 20-30 microns, which allows you to get rid of tiny particles.

Due to the limited filtration rate, cartridge devices are not suitable for high pressure areas. After the expiration of the service life, the cartridge must be disposed of, and a new part must be placed in the flask. The body is equipped with a sump and 2 branch pipes: the first passes tap water, and the second receives the purified composition.

In addition to the listed types, high-speed pressure pre-filters are offered on the market, which have improved performance and throughput.

Filters come with the following placement of the housing:

1. With a straight line - they are installed perpendicular to the pipes and differ in large dimensions.
2. With oblique - occupy a large space and are placed at an angle to the main pipe.

Also, filter systems may differ in the way they are installed. Depending on the installation method, the following categories of devices are distinguished:

1. Flanged pre-filters. They are located at interchanges and main pipelines in the basements of multi-storey buildings. Mounted on pipes with a diameter of 2 inches (5.08 cm). The place of installation is selected after drawing up the design.
2. Sleeve filters. Designed for urban apartments and mounted on pipes with a diameter of up to 2 inches (5.08 cm).

The easiest: flush filter

• What is good: works without cartridges
• What is bad: filters only mechanical particles

This is, indeed, the most elementary filter, which is capable of retaining only mechanical particles ranging in size from 20 to 100 microns. Roughly speaking, this is a small glass in which a grid is installed. The beauty of such a filter is that there is no need to change any cartridges here - just open the drain valve, and the device will “self-clean” under the pressure of water.

This type should definitely be put on the input highway. It will facilitate the work of other filters (they will not clog quickly) and provide more or less clean water for faucets, washing machines, showers.

Some of the most reliable (but also expensive) backwash filters are Honeywell.

7 Barrier VM 1/2

This model is intended for purification of cold, up to 35°, water from ferruginous and mechanical impurities. It is allowed to use it in a centralized water supply system, in wells and wells, as well as at local points to protect household appliances. Rust, sand, silt are removed well, so the filter is often placed as the first stage in an integrated water treatment system. For stand-alone operation, it can be effective if the initial water quality and taste are close to ideal.

The body of the device is made of glass fiber reinforced polypropylene, a material with high rigidity and impact strength. The maximum pressure should not exceed 7 atm, the minimum effective pressure should not exceed 0.5 atm. According to reviews, the filter can withstand 8.5 atmospheres. The affordability of replaceable elements is also recorded in its merits (an average of 800 rubles). They need to be replaced on average 3-4 times a year.

Selection rules

So, we have dismantled water filters for water purification in a private house. As you can see, the classification of devices is considerable, there is plenty to choose from

But here another question arises - what, in addition to the above, should be additionally paid attention to in order to make the right purchase. There are three positions here:

1. Number of cleaning steps. In this case, the more, the better. But this increases the cost.
2. Instrument performance. Everything will depend on how many people live in the house. The more, the more powerful the filter installations will have to be installed. And this will again affect the budget.
3. Filtration features. Again we return to the analysis of water. For each impurity, you will have to select your own filter.And the more pollution there is in terms of diversity, the more the water filter installation kit in a private house expands. And this again will affect the increase in cost.

Video description

The video talks about a softening column, as a type of filter for cleaning water in a private house from a water pipe, well or well:

Briefly about the main

Summarizing the topic, I must say that today living outside the city, far from the fruits of civilization and getting clean water at the same time, is not a problem. There are a wide variety of filters on the market. The main thing is to make the right choice. And it should be based on common sense. For example, you can hardly expect clean water from the nozzle within 5-10 years.

How to choose the right cleaner?

Away from the city, the supply of water in most cases is organized by extracting it by drilling a well or digging a well.

Well: what is the difficulty of cleaning?

A well is a source of water, the layers of which are not deep.

This feature of the organization makes water pollution possible:

• ingress of sewage in case of defects in cesspools and septic tanks;
• chemicals that enter the soil with fertilizers, etc.

The well, which has not been used for its intended purpose for a long time and has been idle, is also a danger. Getting water from such a source can be organized in the following ways:

• pump installation;
• extraction of water in a simple mechanical way - a bucket.

If the second method is used, then only a jug can be used as a filter. The pump gives more opportunities - with it it is possible to install both main and flow-through water treatment.

Wells: 4 organization options

The organization of a well in a summer cottage allows you to provide yourself with water for technical needs and consumption. Well types are determined by drilling depth:

Well type	Peculiarities
Supreme	The most shallow. They have the same list of disadvantages as wells - a high probability of contamination with substances from the soil surface and wastewater. Such wells without cleaning can only be used for irrigation purposes.
On sand or stone	Wells have a depth of 10 m to 15 m. Such an organization is most common. Geological rocks (sand and stone) in themselves are primary filters that trap part of the pollution
Artesian	Produced from deep layers of occurrence, such water is considered purified from most chemical and biological contaminants.

1. individual;
2. collective.

If the well is located on its own site, then it is possible to organize a separate cleaning system, including not only a deep pump, but also main cleaning and the use of filters. For those that serve to supply water to several land plots, the filter is selected taking into account general needs.

In this case, only mechanical treatment may be sufficient if the water will go mainly for irrigation. It would be wise to organize a higher degree of purification on an individual basis.

1 Fibos for cold water 1000 l/h

The Fibos Trade company suggests using a carbon filter on a cold water supply (up to 40 °) in order to clarify it, remove chlorine and eliminate unusual odors and tastes.Thus, active chlorine is eliminated by 100%, heavy metals by 98–99%, hexachlorocyclohexane (a pesticide widely used in agriculture) by 95%. Filtration is carried out by a replaceable cartridge with activated carbon made from coconut shells. The special technology of pressing the sorbent prevents the re-emission of contaminants into the purified water.

Among the advantages of the device, users call efficiency in the fight against the smell of bleach. According to them, the water really becomes much lighter and tastes better. The indicated productivity (1 cubic meter/hour) is enough for drawing water in a small house or apartment for 2-3 people. If there are more users, it is required to select a flow system with a throughput increased to 3 cubic meters per hour. It should also be borne in mind that with severe contamination of the main water, one purification stage will not be enough.

Attention! The above information is not a buying guide. For any advice, you should contact the experts!

Kinds

Fine or deep cleaning is understood as a set of processes, for each of which there is a separate type of filter elements.

Multilayer fabric

These blocks are made in the form of a cylinder with a continuous circular winding of textile strips, bundles. Multilayer fabric filters can purify both cold and hot water.

The fabric layer does not provide very deep cleaning, the water thus obtained can be supplied to sanitary equipment.

fine-meshed

An alternative to filtering on several layers of fabric is water purification on metal meshes with a large number of small cells.

There are modifications of mesh filters with a silver-plated surface.They can not only retain debris, but also have a bactericidal effect on water.

Reference! Metal meshes are convenient because they can be easily and reliably washed from adhering dirt.

Elements with polymer filler

Polypropylene cords or granules are most often used as a filter element. The technology for the production of a polymer with a large number of cells and pores has been developed.

Polypropylene actively retains impurities. Possibilities of fillers can be restored by washing.

Filter blocks with mineral fillers

Have good filtering ability

• clay,
• silica,
• silica gels.

Minerals are carefully cleaned, calcined to increase porosity, washed and used for purification. The nature of the filler significantly affects the sorption capacity.

Interesting! So natural alumina absorbs mainly organohalides, arsenic derivatives.

Shungite purifies water from a large number of impurities. Zeolite exhibits not only filtering, but also ion-exchange properties, removes many substances from water, including hardness salts.

active carbons

Coals in the activated state are characterized by sorption capacity in relation to a large number of impurities.

The following is used as a source for obtaining sorbents:

• wood,
• shell nuts;
• fruit bones,
• coconut shavings,
• stone coals,
• peat.

The disadvantage of active carbons is the need for frequent replacement. Several times it can be restored by washing. The number of regenerations should not exceed four times, after which the coal must be disposed of or thrown away.

Ion exchange resin systems

An example of a natural ion exchange material is zeolite.In practice, specific polymers are often used to fill ion-exchange columns. Charged ions are movably attached to them.

During the passage of the water flow, the cations of hardness salts are exchanged for sodium cations. As a result, the water softens. Ion exchange resins can be regenerated by aging in a common salt solution. Fillers are inexpensive, successfully cope with part of the pollution.

Reverse osmosis systems

Reverse osmosis is the process by which a pure liquid, such as water, passes through a membrane. On the other side of the membrane, all the dirt remains, the liquid concentrate with impurities enters the drain.

Only previously purified water can be supplied to the membrane element.

Therefore, several blocks are installed in the system:

• rough cleaning;
• sorption;
• ion exchange;
• reverse osmosis.

In some units, at the final stage, the water is subjected to mineralization.

Initial parameters for selection

The process of choosing any purifier begins with the analysis of water taken from a well or well.

The results obtained reflect the nature and degree of water pollution from the source and are used in the selection of resources for filtration elements.

• Deep springs supply water with a high content of hydrogen sulfide, iron and hardness salts.
• Fences located near open drains or industrial facilities have elevated levels of lead and heavy metals.
• Open or shallow sources present a biological hazard.

Attention! It is impossible to select a system based on generalized information, the exact composition reflects only the report of accredited laboratories.

Other influencing factors are:

• expected performance;
• place of installation of systems;
• discharge volumes.

The installed system should provide clean water supply, taking into account the needs of residents (from 150 liters per 1 person per day) and correspond to the volume and type of septic tanks. Mistakes at the initial stage of performance selection are fixable, but costly.

With the right approach, all the main elements of the system are located in a separate heated room (which is especially important when using powerful modules).

The filter should be located away from:

1. pieces of furniture,
2. gas communications
3. heating equipment.

An exception is made for expensive filters for post-treatment of drinking water located in the kitchen and separate devices for preparing water for technical needs, installed directly. in front of hot water equipment.

The completeness of the filter is carefully thought out, all main and auxiliary units (including storage tanks, pressure control devices, bypass lines for shutting off and washing filters) are securely fixed in place.

Important! With limited space, preference is given to multifunctional cylinders with a universal filter load, hidden in the kitchen or corridor. Free access is provided to all nodes of the system.

Conclusion

Unfortunately, every year the tap water only gets worse. Today, many people believe that even when cooking, you should not use untreated tap water. Solving the problem of drinking water at home is very easy. With the advent of filters for washing, you no longer have to carry heavy canisters from the store or wait for hours for a delivery service. The rating of the best filter systems will help you make a choice, it presents the most popular high-quality models.

It doesn’t matter which system you decide to give preference to, flow or reverse osmosis, the main thing is that it meets all your requirements.

This rating is subjective and is not an advertisement.
