"Without water - and not there, and not here." An excerpt from a well-known song in an original way makes it clear how much liquid is necessary in the process of life not only of a person, but of all living things. Without it, life on the planet would not exist. In order to develop and function, the human body needs a daily supply of drinking water in an amount of at least one and a half to two liters, which undergoes constant high-quality cleaning thanks to special filters. Below are some of the best reverse osmosis water filters.
What are the products
The main structural element of the device is a special cartridge. Depending on its reliability and characteristics, the life of the product itself depends. There are such varieties:
View | Description |
Coal | They work on pressed (activated) carbon. Eliminate inorganic and organic components, affect the color of the liquid, remove unpleasant odors. |
Mechanical | Contains polypropylene. The main purpose is to remove mechanical suspensions, rust and sand. |
Iron removers | The presence of two fillings, one of which is calcite, helps to improve pH, remove hydrogen sulfide, eliminate metallic odor and taste. |
Softening | The composition contains Na-cationic resin. Purifies water from heavy metals. |
The best manufacturers produce these types of popular filter models:
- Standing separately. It must be connected to the plumbing system with a flexible hose.The maximum number of filtration stages is two: activated carbon and polypropylene. A 10-inch cartridge is enough to enjoy clean water for six months. On average, it is designed for 4 tons of liquid. Can be installed both on the sink and on the wall. Popular companies produce models with an indicator warning that it's time to replace the cartridge. Replacement occurs once every 4 - 5 months. You can enable or disable filtering. In this case, the hose must be disconnected.
- Attachment on the crane. Has a carbon cartridge. Withstands a flow of no more than 2-3 liters per hour. Can't handle large volume.
- The filter is a pitcher. The best for giving. It is reasonably priced and easy to use. Operates on a carbon cartridge. The maximum volume of water for filtration is 500 liters. The following varieties are produced: specialized and universal. What to pay attention to? The former have additional options that allow you to remove iron, soften the liquid, add fluorine.
- Trunk. Its place is the main pipe, through which water is supplied to apartments and non-residential premises. Can be installed on both hot and cold water. We are ready to make water suitable for drinking and protect plumbing fixtures from premature failure. Extends the life of household appliances connected to the central water supply, mainly washing machines and dishwashers.
- Filters for water purification under a sink. Connection point - water supply. Differ in efficiency and productivity. The composition contains three cartridges. You can change the filtration method by installing the required cartridge. The first stage of cleaning is always of a mechanical type.Able to rid the liquid of any contaminants, regardless of the flow rate.
- Purifier (cooler). Stationary type water purification devices are considered the best-selling ones. They are also able to heat or cool water to the desired temperature. They differ in modification, parameters, functionality. Installed in offices and manufacturing plants.
- Prefilter Attaches to a water pipe. Eliminates mechanical debris, protecting rubble equipment. Contains fine mesh. New items are produced with water hammer protection. Requires periodic flushing.
- Tourist. Taken on trips, business trips, hikes, trips. With the task - filtration of liquid from any source, copes with honor. Can be used in difficult conditions.
- Nano filter. Nano technology is used in their production. The manufacturer equipped his offspring with a semi-permeable type membrane with pores, the dimensions of which are similar to those of a water molecule. Capable of retaining all impurities.
Each system has both its pros and cons.
Features of choice
The main task of filters is to qualitatively purify the liquid. Used to filter both drinking and domestic, cold and hot water. Multifunctional devices are equipped with water pipes, so that the liquid intended for the home or office space is cleaned. Products for hot water endure high temperatures, as they are made of solid and high quality materials.
According to buyers, you should carefully consider the filtration steps. They help to eliminate from the liquid:
- nitrates;
- pesticides;
- active chlorine;
- cadmium;
- phenol;
- colloidal iron;
- oil products;
- heavy metal ions;
- organic impurities.
To avoid mistakes when choosing, you need to pay attention to the dimensions of the connection. They are: 3/4″, 1″, 1/2″.
Selection Tips
The functionality of a product is directly related to its capabilities. Which filter is better to buy depends on many factors. Everyone has different selection criteria. But there are recommendations from experts that are worth listening to. A review of the models shows that the variety of products produced is impressive. To make the right decision, you need to understand the design features and functionality of the purchase. Filters are:
- With reverse osmosis, where the main filter valve is the membrane. It traps bad impurities in the water and sends them to the sewer system.
- No reverse osmosis.
- With capillary membrane. Equipped with designs for washing. The membrane consists of capillary tubes, allowing to clear mechanical debris and bacteria, while maintaining the mineral composition.
Not intended for hard water treatment. The presence of heavy pollution requires the installation of a pre-filter.
- with mineralization. It is considered a useful and necessary process. A unique result is achieved: water becomes tasty and healthy. Mounted on reverse osmosis filters.
- With ultrafiltration. Designed not only for residential buildings, but also for wells and wells. Able to cope with bacteria and germs. Auxiliary reagents are not used, the physical and chemical composition of the liquid does not change.
- With heating and cooling option. In most cases, coolers are equipped with it, but it can also be found in other multifunctional devices.
- With cartridge replacement indicators. A special element that will tell you that it's time to insert a new cartridge.Users rarely keep track of the end of the operational life. As soon as it ends, the filtering becomes not so high quality.
- With delivery of a separate crane. Basically, this system is designed for filters installed under the sink. This significantly reduces the cost of production and does not require additional purchase of suitable connectors.
- With pump. The main task is to increase the pressure. There are times when the pressure in a conventional water supply network is not enough for the filters to function properly. Then pumps come to the rescue.
The principle of operation of the reverse osmosis system
Regardless of the rating and the manufacturer, the product package is identical: replaceable special modules. The design features of reverse osmosis devices are practically the same. They have a standard set of filter elements, the service life of which ranges from 3 months to six months.
The following cleaning steps are provided:
- iron removal;
- rough;
- ultra-precise;
- water softening;
- post-filter - mineralizer.
The fine cleaning module operates according to the following principle:
- An ultra-thin membrane separates the knot.
- Pressurized liquid enters the first compartment. There is a process of primary purification.
- Passing the second membrane, the liquid enters the second half.
How to choose a reverse osmosis filter for an apartment
The main characteristic of the product is performance. Much depends on the needs of family members. For a full-fledged family of three to four people, a model that is able to process 5 liters of liquid per hour is suitable. Equally important is the reliability of the design. Operation is associated with various loads. The device must be stable on the surface or be properly fixed.It is desirable that impact-resistant materials are used in the manufacture. Otherwise, damage to joints, leaks and other troubles cannot be avoided.
The rate of fluid collection depends on such factors: device features and water pressure in the system. High pressure cleans faster. The recommended indicator of the maintained pressure is 3.5 atm. Ease of use and ease of installation play an important role. The kit should consist of fasteners, fixing clips, seals. This will allow you to mount the device yourself. If valves, diaphragms and modules are equipped with quick-detachable connections, then this improves the process of their further operation, makes repairs simple and quick.
Reverse osmosis products are among the most common and effective. They have found wide application in the desalination of salt (sea) water, wastewater filtration. Irreplaceable assistants in medicine, food industry and other industries.
How to choose the right fixture? It is worth paying attention to the following characteristics:
- Membrane porosity. The indicator affects the throughput and quality of cleaning. The best option is 1 micron. The average is considered to be 3 microns, satisfactory - 5 microns.
- Performance indicator. The reference point is a minute. The average value is from 80 to 250 ml. Manufacturers produce devices capable of passing a flow of up to 1 liter through themselves. When using the product in everyday life, the indicator will not play a big role. When purchasing for cafes or restaurants, the value should be close to 1 liter per minute.
- Storage tank volume. Its presence makes it possible to improve low performance. Capacity - from 4 to 12 liters.Inside there is a rubber pear with air. Helps to increase the pressure of the liquid when leaving the tap. As soon as the pressure weakens, additional filtered water enters the container. Such a container makes it possible to simultaneously use clean liquid by all family members even in the event of a shutdown of the supply through the water supply system.
- Lower pressure limit. The reverse osmosis membrane requires the passage of liquid under a certain pressure. If the indicator is lower, the cleaning quality is reduced. The indicator is different for different models. Devices are produced with a minimum value of 2.8 atm. Others require 3.5 atm. If your system cannot produce such an indicator, you should think about purchasing devices with pumps.
- Appearance of the crane. Spouts can be equipped with one or two valves. The latter are produced single-lever or with a turn in different directions. In this case, you can choose one of the types of water: mineralized or filtered. If you are not going to drink mineralized liquid, opt for a single-valve faucet.
- Options. It is worth paying special attention to this nuance. If you miss the dimensions, there will be installation problems, since the product may not fit under the sink. Before you go to the store for a purchase, you should measure the free space using a tape measure. It is worth choosing a model with suitable parameters.
The best reverse osmosis systems with booster function
These models have special pumps. Thanks to them, you can increase the pressure to the desired value. An indispensable thing with constant weakening of pressure.

Conclusion
There are things you can't skimp on. This also applies to the quality of drinking water.Today, the ecological situation is not up to par, so you need to try to protect yourself from all the troubles associated with eating low-quality products, including water. It's no secret that many industrial enterprises dump waste into rivers, from which water is then taken to supply the population of both large cities and small towns.
If you do an analysis of the liquid, then there is the entire periodic table. Quenching our thirst or cooking food on it, we automatically poison our body. Therefore, today allergic reactions (even in small children) are not uncommon. Components from bad water not only settle in the internal organs of a person. They accumulate in the soil, which negatively affects the quality of growing plants. You can protect yourself only with the help of water filters. It is worth considering the acquisition of these structures. Then you will have the opportunity to drink living water, as if from a primordial source.
