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: Mostly plastic
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.

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.
Pros
- WQA-certified lead reduction; NSF-certified for chlorine and many contaminants
- Filters on demand at the tap - no plastic pitcher to refill
- Best-selling, widely available, inexpensive
Cons
- Marketed on contaminant reduction in a way that obscures the all-plastic path
- No plastic-free configuration exists for a faucet-mount filter
Notes
- Faucet-mount housing and spout: BPA-free polypropylene/ABS (brand states BPA-free plastics)
- For a plastic-free filtered-water path, a stainless gravity dispenser routes the water through steel instead
