Review on Filter under the sink Geyser Prestige Smart by Adam Adam ᠌

Bought two years ago. I decided not to write a review right away for the following reason. Initially, it was a little junk - the water constantly drained into the drainage and made a little noise. They came from the warranty workshop and fixed it. A year has passed - everything is fine. Compact size thanks to three cartridges and wall mounting. What was important - there is not enough space under the sink. I installed a simple mechanical filter at the inlet. As a result, I haven’t changed a single cartridge in a year and so far I don’t see the need. The parameter measured by TDS does not change and is in the region of 30 units.
