PUR PLUS Faucet Mount Filtration System
The #1 selling faucet-mount filter reduces lead and dozens of contaminants, but the entire housing the water flows through on its way to your glass is plastic - so it is not plastic-free.
The verdict: Significant plastic contact
PUR is the #1 selling brand in faucet filtration (Nielsen US sales), and the PLUS faucet mount (FM-3700B) does its headline job well: it is WQA-certified to reduce lead and NSF-certified to reduce dozens of other contaminants. But the housing itself is the problem here. From the tap, water enters a BPA-free plastic mount, passes through a plastic-encased filter cartridge, and exits a plastic spout - the water's entire contact path is plastic on the way to the glass. Included as a corrective: a faucet filter cleans your water of contaminants while routing every drop through plastic.
What it's made of
| Part | Material | Water contact |
|---|---|---|
| filter housing / mount body BPA-free molded plastic housing; filtered water flows through and exits here; specific resin not confirmed (notes mention polypropylene/ABS as an unconfirmed guess) | Plastic other / unspecified | Yes primary |
| diverter valve and spout BPA-free plastic diverter and output spout the filtered water pours from | Plastic other / unspecified | Yes primary |
| filter cartridge housing plastic-encased activated-carbon and ion-exchange filter media | Plastic other / unspecified | Yes primary |
| exterior shell chrome-finished plastic exterior (cosmetic) | Plastic other / unspecified | No |
PUR's PLUS faucet-mount system clamps onto a standard kitchen faucet and filters water on demand - no pitcher to refill. The 3-in-1 cartridge is certified to reduce lead, chlorine, and dozens of other contaminants, rated for about 100 gallons before replacement, and PUR is the category's best-selling brand. Inexpensive and widely available.
