The PUR Plus Faucet Filtration System finished first in four of our seven sources, including the hands-on rankings at WaterFilterGuru and Quality Water Lab and the Tap Score lab panel at TechGearLab. Across those tests it reduced more than 70 contaminants and dropped lead and PFNA to undetectable levels, all backed by NSF/ANSI 42, 53, and 401 certification. No other faucet-mount filter paired that breadth of verified removal with that depth of independent agreement.


What It Won't Do
Filtered water comes out slowly at roughly 0.54 gallons per minute, and both TechGearLab and Quality Water Lab singled out the sluggish flow and bulky plastic body.
The Brita Basic carries the same NSF/ANSI 42, 53, and 401 certification as filters costing more, reduces 60-plus contaminants including 99% of lead, and sells for about twenty dollars. Consumer Reports rated it very good across flow, clog resistance, and flavor, and Quality Water Lab confirmed its certification scope. For most kitchens it delivers the certified essentials at the lowest credible price.

What It Won't Do
The plastic housing feels flimsy and a few owners report leaks, and Consumer Reports noted that a year of replacement cartridges can cost more than the unit itself.
