Sorry that this did not work out. I was shocked to see the TDS reading was higher post filtration (approx250ppm) than the TDS of the source water (approx 200 TDS). I returned both units promptly and am still waiting for my refund.
Great solution for my husband and myself. We are on well water and were buying tons of on gallon water bottles in plastic and we go through so much every week that this is a great temporary solution for us until we can get our kitchen built and put a system under our sink. The water taste great from this RO countertop carafe.
Overall I really like this. Design is nice on the counter and water tastes good. The only 2 things I would point out are: the filtering process is quite loud and the tank is small therefor you’re refilling it often.
