Do you have any tap water filters that you can drink directly after filtration?
I have a small home that is about the structure of the following 3 filter barrels, coarse filtering first Ppmian
finally into the probably a filter to improve the taste, the water is not great, but the night can turn the water heater for our more than 200 liter is full, Saehan sign, about more than 2000, for your reference
second active carbon, third 5u m Ppmian filtering impurities then enters the pressure pump pressurized into R0 reverse osmosis filtration is greater than water molecules including virus like so can drink
