This filter is useless. My TDS from tap is about 290 ppm and with this filter it's about 240 ppm while my osmosis system is 15 ppm. I thought my old filter was getting dirty because it read similar reading before installing a new one I guess it's just the filter itself overall is useless. Returning and will connect my osmosis system to the frig instead....don't want to get myself killed.
