Reverse osmosis filtering is brutal though. I think the most efficient ones are still like what, 1:2? 2 parts waste per one part clean water produced? It's a lot of wasted water. Even if it was 1:1 it would be terrible, that's doubling water usage.
Fine for drinking water, but showing/toilets/machines it's a lot.

- SirFatty 1y agoAgreed... I have one in the kitchen for a while, but the constant water going down the drain sound drove me nuts, not to mention what a waste it is.
- yetihehe 1y agoThey are 1:2 parts when filtering out salt water, because they need to clean out a lot of salt being concentrated before membrane. When filtering clean drinking water containing promiles of pollutants, the ratio would be much better.
- Night_Thastus 1y agoHome units, just filtering tap water, get about 1:2 with pressurization - and worse without a dedicated pump.
