Review on Under sink filter Atoll A-550m STD 1/2" white by Mateusz Sowa ᠌

Almost a year has passed since the purchase and installation of this reverse osmosis system and it's time to write some of my impressions. 1) As for the mineralizer at the 5th stage, here it iscombined with a carbon post-filter, a kind of 2 in 1, that is, it will clean the water after the tank and saturate it with minerals so that you don’t drink distillate at all. On the market, I found only one such cartridge - Pentek GS-10CAL / RO, in fact, itcomsts out of the box. I am not going to change it in the future to a bunch of the 5th stage post-filter and the 6th stage of the mineralizer, because there will be no profit in terms ofcomst. 2) As for the membrane: from the factory itcomsts Filmtec 1812-50, with a capacity of 50 gallons per day, if desired, you can put it on 75 gallons, but with the replacement of the flow restrictor, I didn’t bother with this, a family of 3 people plus a cat enough for the eyes. More about the membrane: our Chinesecomrades have been producing similar membranes for a long time and selling them on the well-known Internet site at a nice price (Vontron ULP1812-50 membrane, for example, which is wrapped in a box with the inscription "Geyser"comsts 900 against 1500. ) But here everyone he decides for himself, I made a choice in favor of ordering a cheaper membrane from the Chinese, but I will replace it not once every two years, but once a year, because it’s somehow reluctant to drink water from under a “tired” membrane at the end of its service life. 3) Replacement of cartridges and resource: original cartridges (American, Pentek) worked out their time without any problems, but after looking at theircomst, it was decided to buy Atoll. In August 2022, the next replacement period was approaching (1,2,3, and 5 stages) and opening the first stage flask with a 5 micron cartridge, onecomuld see the following: . Having somewhat precipitated from such water, and having examined other cartridges, it was decided to replace the membrane as well. So henceforth it was decided to reduce the replacement period of the first stage to 3 months, and the membranes to one year, the rest without changes. Now I took Barrier cartridges, let's look at them.
