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

It is the gradual decrease in the throughput of this part by 10 or more times that reduces the filter performance and its life from the declared parameters to premature "death" within 1 month. Some pros: Excellent water quality, filters available, easy to change, good instruction manual. Fills the tank fairly quickly: 1.5L in 10-12 minutes, 6L in 40-50 minutes. I have been using this filter since 2022. Has some cons ATTENTION! The instructions do not state that when changing the membrane filter (24-30 months), it is necessary to simultaneously change the "flow restrictor, model A420". This part is worth in the rupture of the tube for draining waste water into the sewer.
