I bought it for a share for 6500. For the full price (12022), I think it's very expensive. There are analogues for 6-8 All filters are the same. Coal and mechanical cleaning. The only difference is in the membrane. There are no breakthrough technologies for twice the price here. I definitely recommend buying, for a price of up to 8000. After 4 months, plaque began to form on the mugs. Replaced pre-filters. Pictured condition after 4 months of use. The first one needs to be changed more often.
