PUR vs Brita Faucet Filter: Certified Breadth vs Simple Taste
PUR and Brita faucet filters look identical but optimize for different buyers: PUR for the broadest certified reduction including lead, Brita for the simplest taste upgrade. Here's how to choose.

PUR and Brita dominate the faucet-filter aisle, and they look nearly identical: a clip-on housing, a filtered/unfiltered switch, a status indicator, a price around $35. But they're optimized for two different buyers, and the difference comes down to one word — certifications.
The core difference
PUR PLUS is the certification-forward choice. Its faucet filters are certified to NSF/ANSI 42 and 53, and PUR's faucet line carries certification for a notably broad list of contaminants — including lead. If you want the widest certified reduction in a clip-on, PUR is the stronger pick.
Brita is the taste-forward choice. Its faucet filter is certified for chlorine taste and odor and common contaminants, with a narrower certified scope than PUR. It's compact, simple, and renter-friendly — optimized for "make my water taste better," not "reduce the longest possible contaminant list." The NSF 42 vs 53 guide explains exactly what that scope difference means.
They agree on the basics
Both give you the things that make a faucet filter livable:
- Tool-free install on a standard faucet
- A switch to toggle filtered/unfiltered (which preserves filter life — see the replacement cost guide)
- A filter-life indicator
- Roughly 100-gallon / ~3-month cartridges
- Neither fits a pull-down or specialty faucet — for those, you need a countertop or under-sink option
Choose PUR if...
- Lead or old pipes is your concern. PUR's NSF/ANSI 53 lead certification is the deciding factor; the lead guide covers why this matters.
- You want the broadest certified contaminant reduction in a simple clip-on.
- You're fine with a slightly bulkier housing.
Choose Brita if...
- Taste is the whole point. Chlorine taste and odor is what bothers you, and you don't need certified lead reduction.
- You want the most compact, renter-friendly unit that comes off in seconds.
- You already use Brita pitchers and want one cartridge ecosystem.
And the alternatives worth knowing
If neither fits your priorities: the Culligan FM-25 matches PUR's lead certification at a lower price (with shorter cartridge life), and the Waterdrop wins on filter life and flow if certified scope matters less to you.
The bottom line
Same shape, different mission: PUR for certified breadth including lead, Brita for the simplest taste upgrade. Match it to your actual water concern — and if you're not sure what that is, the faucet filter quiz starts there and narrows to a certified pick. Browse all options on the faucet water filters hub.
