Geyser Nanotech

Advantages: Filters water, relatively easy to connect, good water pressure due to reverse osmosis.

Disadvantages: The need to buy additional equipment (pressure gauge) to measure water pressure. If the pressure is below 3 atmospheres, then the filter simply will not work. + 450r. You should carefully check the package contents upon purchase. I did not have a crimp for the drain pipe and had to buy it separately. He took, as they say, "without looking" and the incomplete was found only at home. + 120r. in the nearest household. It is required to install an additional tap (for this you need to drill a hole in the sink or countertop), or replace it with a tap with a filter channel. I didn’t smoke the sink, I had to go for a replacement, because the second crane, sticking out nearby, looks very collective farm and is simply inconvenient to use. The whole system takes up a lot of space under the sink.

Comment: I did not notice any special differences in taste between unfiltered and filtered water, it did not become tastier. Although there are visual differences, if you pour water into a glass, then the tap water has a yellowish tint (South-West Administrative District, Moscow), filtered - crystal clear. Scale does not form at all: for half a year, the kettle has not been washed from it even once! Previously, you had to get rid of it once a week. UPD from October 2017: After a year of use, I decided to change the filters in the cartridges. If before that I was not completely sure that such a filter was a necessity in the apartment, then after I took out the old filters from the cartridges, I was convinced that the filtration of tap water is not just desirable, but even obligatory! In the coarse filters, I did not find anything supernatural: sand, a lot of rust, some scraps of either grass or leaves. The most interesting thing was contained in the membrane filter. Inside, an incredible amount of some kind of brown stuff was found that had an unpleasant swampy smell (almost 60% of the volume, starting from the entrance from the coarse filters, was clogged with it). If you still think that drinking water from the tap is of good quality in Moscow, then this is far from the case. It is better to get confused with the installation of an osmosis system, such as this filter, since flow filters cannot fully filter microscopic algae and bacteria, which, despite abundant "chlorination", are still present :(

Advantages: Was bought by parents to replace the jug, the water tastes great.

Disadvantages: The kit did not include a sealing rubber for the storage tank tap. After starting, water accumulated under the sink.

Comment: Always install during the day, do not leave unattended after installation

Advantages: 1) filters, the water is clean and tasty, clear and does not smell (Moscow). 2) measured by TDS: at the entrance 180 units. at the filter outlet 20 units. , thus the degree of purification from water-soluble salts is 90%. 3) well, of course, there are no scale and films. 4) a membrane of good quality, it has been working for three years without any complaints (consumption of clean water per year per family: 2000 liters, measured by the flow meter on the filter).

Disadvantages: 1) when filling the storage tank: the ratio of clean water and drained into the sewer: 1 to 5 (that is, 6 liters of water will be consumed per 1 liter of clean water, 5 liters will go down the drain). Measured it on purpose. 2) when water comes out of the tap directly into the glass: the ratio is 1 to 2. That is, from 3 liters of water, 1 liter of pure is obtained. 3) well, like everyone else in this design, it is inconvenient to change cartridges (but this is to find fault if)

Comment: Costs per year: a set of Geyser S-1 cartridges: about 900 rubles and a Geyser post-filter about 400 rubles ... That's it.

Advantages: The outlet water is really clean, soft, transparent. With all the tools, thoughtful, unhurried installation takes 2 hours. Storage tank. (Even if the water is turned off - you have 8 liters of clean water)

Disadvantages: Lack of fasteners for pipes on the filter body (hoses stick out ugly in different directions) Inconsistent quality and forgetful pickers.

Comment: Overall, I am very pleased with the filter. Water quality is not comparable to three-stage filters. Advice for those who are going to install themselves - read what tools you need (Drill for 12, fum-tape, open-end keys) All installation instructions were removed on 1 A4 sheet in large text, the rest - Here's a diagram, collect on it. Their negative - the pickers forgot to put a sealing washer for the tap, which is screwed onto the storage tank - as a result, the water leaked (disassembled, wound the fum tape, tightened it tighter - the problem was solved) From the reviews it follows that I'm not the only one who is not alone reported. And yet - a beautiful inscription on the packaging says "A set of cartridges as a gift" - it exists, but for some reason it is from the Geyser Prestige model. Physically, it will fit, but the set of filters is different, and there are only 3 cartridges for the pre-filter in the kit.

Advantages: Easy installation. Possibility of branded free installation. High consumption compared to reverse osmosis. Water tastes good. Does not require power supply.

Disadvantages: Just the price. Almost 10 thousand, then it was not cheaper - this is not a little. For a model without a pump (pump), the pressure in the water supply system in front of the filter must be at least 3.0 atm (bar).

Comment: I have been using a reverse osmosis filter for over 11 years. The water was like distilled water. A valve with a drive failed and allowed water to flow into the drain. Noticed accidentally when cleaning the siphon in the sink. The overrun of cold water on the meter became clear. I decided to change the filter. I deliberately decided to change "osmosis" to "ultrafiltration".I read a lot, and I also felt that with "osmosis" additional mineralization is desirable to maintain health. I chose Geyser Nanotech. I installed it myself, since I did not read in the passport about a possible free installation, and after the "osmosis" no difficult operations were planned, all the inserts are existing. That's what's important! The standard kit does not include a booster pump, so the pressure at the cold water inlet to the filter must be at least 3 atmospheres. Otherwise, the drainage mechanism may not work to close after flushing and there will be a constant leak of water into the sewer. It happened to me, I had to reconfigure the inlet pressure regulators (they are adjustable) from 3 bar to ~ 3.3-3.5 bar and the problem was solved. Everyone really likes the taste of water, especially after the period of time our previous filter has failed. Water consumption is much higher than that of "reverse osmosis".

Advantages: Corresponds to everything that is stated. Installation is possible independently, by hand from the right place

Disadvantages: different cartridge resources. it is not convenient to monitor the replacement frequency.

Comment: in a set of replaceable cartridges instead of a BAF filter, a second carbon was inserted. what for?

Advantages: The water tastes good, there is no scale.

Comment:

Advantages: The water is clean, less than 10 by the NDS meter. Of course, it will grow over time.

Disadvantages: Until the minuses are identified, we'll see over time

Comment: Anything is better than a tap. But it is better to order a mountain mineral for health. This one has nothing, nothing at all. Neither bad nor good.

Advantages: Robust hose connection design

Disadvantages: Takes up a lot of space under the sink

Comment: Clear instructions, fast installation. I also have a kitchen chopper under the sink, so you can forget about the big bucket. The water is clean, no limescale in the kettle and no smell. I am satisfied with the purchase - I recommend it!

Advantages: Promotional price in the store, quality, membrane.

Disadvantages: It seems to have met my expectations.

Comment: It was recommended to us as an ideal filter for families with small children, though they didn't really explain why. Initially, they wanted a reverse osmosis system, in the end they recommended Nanotek with a membrane. The delivery includes a crane, cartridges. We ordered the installation free of charge, did not risk it ourselves. Cleans water well, perfect for our water with increased hardness! Bought for a promotion, which makes us very happy)
