I can’t drink the water directly from our faucet so was really excited about this filter. It is really simple to install, just unscrewed the cap and screw the water filter into place. Then screw it onto the faucet, 3 different sized connectors are included, only took a couple of minutes to install everything. Flip the leaver down for filtered waster and be sure to run water through for 5 minutes before using. Our water is much more palatable now. Easy to flip the leaver for filtered water or not, when washing dishes etc. The CleanSensor Monitor indicates when the filter life is over, which is approximately 90 days.
