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

Excellent filter for drinking water. Ten years ago I put one in the country. Very easy to install and excellent workmanship. In an apartment in Hong Kong, I first installed Atoll D-31, but without osmosis it is a waste of money. Scale appears after a month of use. Therefore, I installed Atoll A-550 with reverse osmosis. Of the advantages, in addition to those previously mentioned, this is a huge selection of replacement cartridges of a standard size from different manufacturers. And of course, the complete absence of scale and sediment after boiling water.
