The PUR Horizontal Faucet Mount Water Filter is a plastic, tool-free filter that clamps onto a standard kitchen or bathroom faucet and switches between filtered and unfiltered water with an on/off lever. PUR says it is the only faucet filter brand certified by WQA and NSF to reduce 70 chemical and physical substances, including lead, and it is NSF certified to cut microplastics. Each filter is rated for up to 100 gallons, or about three months of regular use, and a change light signals when to swap it. It suits renters and anyone who wants filtered tap water without a plumbed-in system, though it will not fit pull-out faucets or faucets with internal aerators.
