Water feels, smells, and even tastes better (no we aren't drinking it on purpose, but whenever a little bit of shower water trickles in, it taste much much better than before). I am so happy we found PureEffect as I trust the legitimacy of the product 100% and the proof is in the water! I would recommend to anyone looking for a legit filter. Also I put the filter cartridge in incorrectly when installing the product but got help immediately upon messaging their site chat.
