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

It is not clear why a carbon post-filter is included in the kit, which filters water that has already passed reverse osmosis. As if in the tank, over time, something will begin to live and spoil the taste / smell / color of water and a post-filter is needed so as not to notice this? Has pros: 1) Relatively inexpensive 2) 3 flasks for filters of any choice for pre-filtration before the membrane. Other models may have 2 flasks for pre-filters - I even met a model with one pre-filter. 3) Flasks with stiffeners inspire confidence. 4) Everything you need is included, except that the drill for drilling holes in the sink was not put in the box. Cons below: You can’t look into the tank and see what’s going on inside and you won’t be able to wash it either.
