I used a water quality tester to measure TDS (total dissolved solids) in various water samples.My home tap water measured 421 ppm (parts per million), which is in the high range. My double filtered water that I buy from a local windmill machine measured 50 ppm.After distilling through this distiller, the water measured 0 ppm!It took me a long time to decide to get this distiller because of the price,but am happy I finally got it. My only complaint is one that others have mentioned....the exit spout for the water is very short so you can't use any other container to catch the water except the pitcher that comes with it....and you even have to have that one positioned exactly in the right spot, or the water will spill off down your counter to the floor...as it did on me once.But with all the news about the drugs and other pollutants showing up in tap water these days, I feel much safer using pure distilled water and taking care of my own minerals.
