If the scale in the kettle and sand in the kidneys - not your choice, definitely need to abandon the use of tap water. Of course, bottled is also suitable for drinking and cooking, but installing filters in the future will be cheaper. Multistage systems are able to disinfect, soften and clean the liquid from the pipes to the state of distillate - you only need to choose your favorite model and install it under the sink. And to orient in this matter will help you our review.
The best flow filter systems under the sink
PENTAIR PRF-RO Merlin - productive filter for a large apartment or house
This system differs from the majority of similar complexes by its “architecture”. Here, all the flasks are placed horizontally between the two stable legs, so that during installation you do not have to drill the walls of the drawer under the sink.
There is no built-in pump, so filters can work only with good inlet pressure (at least 2.8 bar). However, if necessary, the pump can be installed separately.
Pros:
- Ability to connect to multiple consumers at once (drinking tap, automatic coffee maker, ice maker, etc.);
- The presence of an osmotic filter with 2 membranes, which ensures maximum water purification from impurities;
- High performance - up to 400 l / day;
- Increased yield of purified water - 20% vs. 5-10% for cheap reverse osmosis systems;
- It is completed with the manometer;
- A large resource of coal cartridges at the inlet and outlet - 18,000 liters;
- The service life of the membranes reaches 3 years.
Minuses:
- Requires primary water treatment and cleaning it from large impurities, as well as softening;
- High price - a complete set of Merlin will cost about 50 thousand rubles.
BARRIER Expert Standard - convenient system with filter indicator
The basic three-stage filter comes with pre-cleaning cartridges for mechanical impurities, an ion exchanger for water softening and a finishing cassette that eliminates unpleasant odors, as well as chlorine residues.
After exhaustion of their resource, the flasks can be purchased in the same composition as a single set or purchased one at a time.
Pros:
- Makes water taste good;
- Big resource (10 thousand liters) - the first replacement of filters will be needed only after 9-12 months;
- Easy installation and convenient cartridge replacement;
- Compact system that does not take up much space;
- Very wide range of operating pressures - from 0.5 to 7 bar;
- Included is an electronic indicator, on the screen where you can see which of the cartridges will soon need to be replaced.
Minuses:
- There is a risk of running into a defective batch, so it’s better to buy a filter at the tested points.
AQUAFOR Crystal Eco N - drinking water disinfecting filter
A rather bulky system designed for simultaneous installation of 4 cartridges provides the finest water purification.
After filtration, even small children and people with gastrointestinal problems or the immune system can drink it without boiling. However, at the inlet, the raw water must be of acceptable quality, with a hardness of no higher than average (up to 4 meq / l).
Pros:
- Extremely simple installation;
- Water does not lose healthy minerals and becomes really tasty;
- Filters remove chlorine, calcium and heavy metals from water, making it softer;
- The ability to regenerate the softening cartridge - everything you need for this is already included;
- The reverse osmosis system with a membrane retains even bacteria, thereby disinfecting water;
- Interchangeable modules - if desired, the filter can be “tuned” to work with water of any quality, using different Aquafor flasks.
Minuses:
- In order for the system to work really long, you need to insert a good pre-filter into the water supply;
- The resource of the softening cartridge is significantly lower than that of the other flasks - it will have to be changed every 2-3 months.
The best filter systems with drive
NEW WATER Expert Osmos MO600 - cleaning and softening of hard water
This system has the richest set of "functions". In addition to the standard prefiltration of mechanical impurities and the radical effect of reverse osmosis, a set of cartridges is able to soften very hard water and remove iron from it.
The MO600 design solution is interesting: all elements of the system here are hidden in separate flat cases. Such a set looks neat, and most importantly - the flasks themselves are reliably protected from accidental strikes.
Pros:
- The low-pressure membrane is capable of operating at pressures in the system from 1-2 atm;
- High yield of permeate (purified water) - 25%;
- The presence of a mineralizer that improves the taste and water quality at the outlet of the osmotic filter;
- 10-liter tank with transparent walls and a removable liner - as it becomes dirty, you can simply throw it away and put a new one;
- Included is a pump block with control electronics to provide the desired pressure;
- Automatic washing of the membrane at the end of each cycle;
- 3 years warranty.
Minuses:
- The price is rather high at the level of 15-16 thousand rubles, but this is only in comparison with flow-through filters without a drive.
KRAUSEN 75 Auto - smart osmotic system with autowash
A modern and effective 5-step system will ensure maximum water purification from any contamination at the molecular level, since it works according to the principle of reverse osmosis.
The complex of filters has a high performance (up to 285 l / day), complemented by a small storage tank, its own pump and built-in mini-computer that monitors the operation of the system itself.
Pros:
- Thanks to the integrated pump, it can even be connected to low-voltage systems with a pressure of 0.1 bar;
- Sufficient storage tank volume - 10 l;
- Long service life of the membrane (2-4 years);
- Automatic washing of the osmotic filter;
- Quiet, non-annoying pump sound;
- The light indication of operating modes displayed on the case
- Thanks to the carbon post-filter, water is obtained without odors and with a pleasant taste.
Minuses:
- Not everywhere is on sale.
ATOLL A-550m STD - filter system with mineralizer
A multifunctional filter with its drive will allow you to get clean water "on demand", without waiting for it to pass through all the flasks.
The system will prepare the desired volume and will serve the drink as soon as you open the tap. Purification is carried out in 3 stages: pre-filtration, reverse osmosis and elimination of extraneous odors with simultaneous water saturation with useful minerals.
Pros:
- Suitable for urban piped water without prior preparation;
- Large storage volume - nominally 12 or 18 liters, depending on the selected modification;
- Coal post-filter with mineralizer improves the taste of water and makes it useful;
- All dirt accumulated on the membrane is removed automatically through a common drain.
Minuses:
- Different resource filters, because of what they need to change each in due time.
