PŪR Water Filtration Systems makes tapwater taste gooder cuz' it's cleaner, selling point "removes unwanted contaminants". Like odor and reducing some of the chlorine (which is the bad taste by the way). It won't remove that US government added flouride you guys have in your tap water which counts as an "unwanted contaminant" in my book. Nor will it remove bacteria and viruses. To remove Cryptosporidium, try just boiling the water instead. Ooops, did I just unsell this thing? Sorry. TBWA\Chiat\Day, Los Angeles might hate me now. I think I'll have a tall glass of pure fresh nice tasting Swedish no flouride tap water right now.
