Review on Under sink filter Atoll A-550 STD (A-560E) 1/2" by Ewa Zawada ᠌

took over 4 years ago. I change pre-filters once a year - they are only needed to protect the membrane from coarse dirt (mechanical) and chlorine (coal). I didn't change the membrane. consulted with the manufacturer - they answered that if the performance did not fall (and the holes did not appear in it - there is no scale) - then there is no point in changing the membrane. performance is high. I have a model with a pump - a liter is poured in 4.5 minutes. I read about other filters here that a liter accumulates in only 10-20 minutes. someone here complained that there were no rubber rings in stock - so they remain from the used post-filter. in addition, the quick-release mechanism itself remains from there. I already have 6 in stock :) the connection does not leak - when inserting the tubes, they must be lubricated with the silicone grease included in the standard replacement kits (this bonus was a pleasant surprise). standard sizes of filters allow you to install cheap analogues from Promfilter instead of expensive P1 and P2. Cartridges already got the hang of changing quickly. the only thing annoying is how to clean the storage tank. or rather, how to then wash the disinfectant solution out of it and what it will wash . I use the filter very actively - in tea and all cooking on water from it. when children were born, I bathed them every day for up to six months in water from the filter (a bath of 10 liters, no less). compared to hard tap water, it does not dry the skin at all (try to wash your hair and wash your face with this water - you will understand).
