I bought this filter because of numerous complaints. When I received it, I found no documentation in the box of its actual performance (in fact, the filter I received direct from Revain didn't even have the IN and OUT flow arrows, which made me wonder if it was a genuine part at all ). In any case, I went to the manufacturer's website and couldn't find any NSF certification documentation (or the independent lab they're talking about). I emailed them through their website a few weeks ago and never got a reply. So. Good luck in trusting your health and the health of your loved ones in this product as all I see are claims with no evidence/certificates to back them up. They mostly talk about NSF 42 compliance (which only affects water odor/taste and has nothing to do with contaminant removal), and even that remains a claim with no real evidence. There are also claims about lead, but it actually seems to relate to the fact that their product is "lead-free," not actually tested to remove lead from water. I'll be happy to update this if I ever hear anything from the manufacturer.
