I am not sure what these filters do exactly. I assume they help to filter to some extent, but the gadget that checks the water seems to give regular tap water the same score as water that has been filtered through your product. Strange right? So who really knows for sure it it is actually doing anything. I am stuck with way too many filters now, so I will continue to use them and just change them once a month or so, since there is no way to tell how long they are "effective". You do not need to keep emailing me asking me to rate you product, or I will take the time to go rate your product with ALL the websites. Enough is enough.
No, I would not recommend this to a friend.

Zero water line of water filtration is awesome. Testing your tap water gives a TDS reading indicating something you don’t want to drink! Even bottled water has excessive readings. Using zero water has a reading of just that - zero TDS. Great tasting water, water as it should be, as it is meant to be.
