Quick Take
Score: 7.6/10 | Faucet mount filters offer unmatched convenience - filtered water on demand without waiting for pitchers to fill. The PUR PLUS is the best mainstream option, though it lacks the comprehensive contaminant removal of pitcher alternatives.
The Research
PUR PLUS is certified to NSF/ANSI Standards 42 and 53 for:
- Lead reduction
- Mercury reduction
- Certain pesticides and industrial chemicals
- Chlorine (taste and odor)
Notably absent: NSF P473 certification for PFAS. If forever chemicals are your primary concern, faucet mounts generally lag behind premium pitchers.
The filter lasts approximately 100 gallons or 3 months - whichever comes first. A built-in indicator light tells you when replacement is needed.
Real-World Testing
Installation genuinely takes 5 minutes with no tools. The adapter system fits most standard faucets, though you'll need to check compatibility with pull-out or spray models.
The filtered/unfiltered switch is convenient - use unfiltered for dishes and cleaning, filtered for drinking and cooking. Flow rate is reasonable at about 0.5 GPM.
The Honest Assessment
What I Love: Instant filtered water without waiting. No pitcher to refill or refrigerator space consumed. The price point is accessible. Installation is truly easy.
What Could Be Better: No PFAS certification limits its usefulness for families with those concerns. The plastic construction feels less premium than stainless competitors. Filter replacement costs add up over time.
The Bottom Line
PUR PLUS is the best choice for renters or families prioritizing convenience over maximum filtration. If PFAS is your main concern, consider a pitcher with P473 certification instead.
