Outdated Product
The Aquafilter filtration system is designed for installation in apartments and houses in conditions of limited space - mainly under the sink. Purified water can be drunk and used for cooking. To do this, it goes through four stages of filtration. First, the FCPS5 cartridge removes mechanical sand, rust, suspended particles of at least 5 microns in size. After it, the FCCST2 cartridge comes into play to soften water and remove iron, which reduces water hardness by replacing calcium and magnesium ions with sodium ions. At the third stage, the three-stage filter cartridge FCCBKDF made of coconut shell carbon, KDF filter medium and polypropylene fibers removes hydrogen sulfide, chlorine, pesticides, phenol, benzene and reduces the concentration of heavy metals: arsenic, lead. But the final st...age of Aquafilter FP3-HJ-K1 uses a capillary membrane that removes contaminants from water of at least 0.02 microns in size, including most bacteria and viruses. The kit includes all necessary connection elements, including filters, a tap for clean water and connecting elements, which ensures ease of installation and use.

Model overview based on user reviews  
The Aquafilter FP3-HJ-K1 is a water filter designed for under-sink installation, offering a four-stage purification process that effectively removes organic impurities, chlorine, ferrous, heavy metals, and pesticides. One user praised the filter for its ability to prevent scale buildup and improve water taste, highlighting the importance of proper installation, including soaking and rinsing cartridges to avoid blockages. However, another user reported a negative experience, stating that after a month of use, the water developed an unpleasant odor, making it undrinkable. While the filter has potential benefits, proper installation and maintenance are crucial to ensure optimal performance.

Filter AQUAFILTER FP3-HJ-K1 - I've been using it for a year now, there's no scale, and the taste is good. I want to share a feature about the installation, specifically the beginning of using the filter. I installed the filter myself, as advised at the time of purchase, but it's not mentioned in the instructions. "Experts" who installed it for friends naturally didn't do it this way (the 4th cartridge was entirely black, why see below).

1. It is recommended to "soak" cartridges #2 and #3 in water for 8 hours.
2. After installation and connecting to the water supply, rinse connected cartridges #1-3 for 5-10 minutes without connecting the 4th main cartridge (capillary membrane), as "carbon dust" will come out of the 3rd cartridge and partially block the 4th one.
Connect the tube that goes to the faucet to the outlet near the 3rd cartridge.
3. Then connect the 4th cartridge, link the 3rd and 4th with a connecting tube, and from the 4th, connect to the faucet and rinse for 5-10 minutes (the 4th cartridge is soaked with a preserving substance, as stated in the instructions).
i’ve been using it for a year now, there is no scale, the taste is good.
