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

Good afternoon! I have been using this filter (previously called 560) since 2022 in the amount of 2 pieces in my different apartments. It filters the water well, but I began to notice in my third apartment (all in MSK) that I want to drink and drink coffee more deliciously, and at home I often don’t drink half of my coffee and pour it into the sink. I was surprised, and then I talked with experts, the water is "dead" and, one might say, not useful. As a result, he threw out the membrane, threw the tank onto the balcony. Satisfied, on the kettle for 2 months. scale appeared with the thinnest coating only on the heating element . and . for 3 years it does not increase anywhere. Before the "improvement", the water resembled a distillate, it's cool, where else can you drink it))) Taking into account the fact that I demolished the membrane and the tank, the conclusion is that for ordinary MSC water, 3 filters are enough, only 1 stage really wears out, the second is not critical, the third, if only under a microscope. After there are no more American filters, but there are Chinese and ours, the advantage of the atoll is generally illusory, any three-stage will do.
