Re: [Rant] Greenlife Water filtration sales

Found the website for these guys, they are rather light on providing technical information, however they do have NSF 42 (National Sanitation Foundation) certified for taste and odour reduction (BDF as does a Brita filter and just about every other filter on the market). They claim lead reduction but don't sight the standard or certification listed for it, elsewhere the only relevant thing I can find for other "Brass alloy filters" is for ANSI/NSF Standard 61 which means the materials used in the filter can't leach out into the water above certain limits. This last point is important as the brass alloy filter (one they dub “KDF”) does emit zinc and copper salts into the water.

They also claim the reduction and elimination of other chemicals however have not (by their own admission) bothered to actually test what that reduction was (if any). They also claim their product makes calcium salts "less sticky" and (key word here) “could” reduce lime build-up.
