Review on Filter under the sink Aquaphor Crystal A, 1/2" white by Adam Gontarz ᠌

I bought the system in November 2022 and installed it right away. The cartridges lasted a little more than 2 months, I contacted the support service, they said to change the cartridges, changed it. After 2 months, the same situation - there is a plaque in the teapot, a dark film on top in a mug of tea. I live in an apartment, there are no strong complaints about the water. Before that, I used a filter jug ​​of the same company - the cartridge was enough for 3 months. I think I threw money away. Do not take advice.
