I assembled and installed it myself at the beginning of 2022, adjusted the filter throughput at the level of 3.5 l / min with a faucet. We drink without boiling for half a year - nothing bad happened, no one got poisoned. The taste of tap water before the filter and filtered differ significantly, filtered water is odorless and tasteless, much cleaner. I use a cartridge with a Japanese membrane (green, it is about 3000), it filters at the bacterial level. True, after a couple of three months, the pressure from the faucet dropped to 2.5 l / min, but I did not increase the pressure with the adjusting faucet in the system, and that's enough. There were no leaks, the installation of the system was simple. if you want to drink non-boiled water, then you need to install a cartridge with a Japanese membrane (green), if only boiled, then it is enough to install it without it (blue, it is about 2022). In general, everything suits, I recommend.
