Review on Filter under the sink Geyser Max white by Ewa Jastrzbska ᠌

We experimented with enough different cartridges to discover a significant difference: this one lasted for 10 months, whilst the others only lasted for a maximum of 6 months. I only deducted one star for the inconvenience of having to use a wrench to unscrew each flask when changing cartridges in this type of filter block, remove the tubes from the block (the tube must be cut off by 2 cm to prevent leakage later), wash the cartridge case inside, and use caution when twisting the cartridges into the housing (TC can skew the cartridge and there will be no filtration). Yet, this applies to all manufacturers who use this type of body design. (Slim type 10)
