Review on Sink filter Prio New Water Start Osmos OU380 white by Dorota Dorota ᠌

I took a relative, I have had one for almost two years. Tap water approximately 270 ppm. On new cartridges, the filter reduces this figure to 7 ppm. The first three steps are changed every half a year, by this time my water becomes only three times harder, i. E. about 20 ppm. They all cost about a thousand together, with the first and third in the region of one hundred apiece. The fourth stage is recommended to be changed every 2 years. But if the membrane is in good condition, then this rule should hardly be strictly adhered to. In my two years of work, the membrane has become clogged quite a bit, and when replacing all the stages, except for the fourth, it shows 13 ppm. Those. I'm not going to change it even after half a year. It costs from one and a half to two with a little thousand. The last stage changes once every half a year or a year. It costs 400-500. Only the second and fifth stages require regular replacement, because. contain activated charcoal. The rest can be changed according to the state. Those. water at a price is no more expensive than in street osmatic machines. A conditional disadvantage can only be considered the need for good pressure in the water supply. It is not very good for me, which is why the 1.7 l kettle is filled in 2-3 minutes. Otherwise, everything is fine, the water is used both for drinking and for cooking. If there is a desire to use water for an aquarium, be careful, there is an ion exchange resin in one of the steps. Exotic snails and other invertebrates will die faster than you can get them, even if you tie them to a string. But for spawning fish, I used it, everything went fine.
