Living in DC, which has probably one of the most disgusting tab waters in the country. It comes from the Potomac river that is highly polluted. With the Sans water purifier I have delicious and clean water. Easy to use and quiet operation is a big plus. The waste water ration is very good.

This little (and very good-looking) machine, has literally changed our lives! We have a house on Fire Island in NY and the water always tasted questionable -- now, with our Sans, we are enjoying the taste of pure clean water but also have confidence that we are are not putting ourselves in harm's way.

The water filters well and tastes great! No mineral residue when heating water from this filter. The machine says the TDS is 3 which is ridiculously low, so I bought a TDS meter to check. It measures 10, which is still ridiculously low. We use our Berkey filtered water to run through the SANS. I checked the Berkey water which had a TDS of 109 and our faucet water was 130, so the SANS definitely removes the TDS. It also processes the water quickly, so you don't wait more than about 5 minutes or less for delicious, safe water.

I would have given it 5 stars except for one flaw. It's really difficult to remove the plastic container that holds the water to be cleaned. I'm 67 years old and have a bad shoulder. It takes a lot of pulling pressure to lift it up and away and always hurts in my shoulder. Then it suddenly releases and I hit my arm or hand on the overhead cabinet. My husband, who is a retired engineer and quite strong, says it's difficult to remove. He suggested perhaps you could create a fulcrum to go under the handle and sit on both ends of the flat top of the unit on each side (not the slots where the container slides in as those areas are weak and can break). That would create leverage to push down and pop it loose easily and you wouldn't have to pull it up. Just a suggestion.

NOTE: It is under the cabinet in the pic and in front of the empty paper towel holder. It does not sit under the paper towel holder which we don't use
