Find Your Perfect Water Filter
3 quick questions. We match you to the right filter type and technology based on your water source, your biggest concern, and your living situation — then show you the top certified options.
Any filter company can claim their product "removes 99% of contaminants." Certifications are what actually back that up. We only recommend filters with third-party certification — here is what each one means:
Tip: A box that says "NSF certified" without a standard number is not enough. Always match the certification to your specific concern — NSF 58 for RO/PFAS, NSF 53 for lead, NSF 401 or P473 for PFAS in pitcher filters.
What is your water source?

Not sure which filter type fits your life? Here is how they compare across the things that matter most.
| Filter Type | Removes PFAS | Removes Lead | Installation | Cost | Best For |
|---|---|---|---|---|---|
| Under-sink RO | ✅ 99%+ | ✅ 99%+ | 30–60 min DIY | $250–$800 | Homeowners, families, PFAS areas |
| Countertop RO | ✅ 99%+ | ✅ 99%+ | Zero — plug in | $150–$500 | Renters, apartments |
| Pitcher (certified) | ✅ if NSF P473 | ✅ if NSF 53 | Zero | $40–$90 | Budget, dorms, portability |
| Faucet mount | ❌ most do not | ⚠️ some NSF 53 | 5 min | $25–$60 | Taste/odor only |
| Whole-house | ⚠️ partial, use RO for drinking | ⚠️ carbon only | Pro recommended | $400–$2,500+ | Every tap + shower |
| Pitcher (basic Brita) | ❌ not certified | ❌ not NSF 53 | Zero | $25–$45 | Chlorine taste only |
* PFAS removal requires either RO (NSF 58) or a pitcher/filter specifically certified to NSF 401 or P473. Standard carbon block filters do not remove PFAS.
Only certified products, period
Every filter we recommend has third-party NSF or WQA certification for the claims on its label. We do not recommend filters based on marketing claims alone. If a company says their filter "removes 99% of PFAS" without NSF 58, NSF 401, or NSF P473 certification, we do not include it.
We check the specific standard, not just "NSF certified"
A filter can be NSF 42 certified (for chlorine taste) but not NSF 53 certified (for lead). These are meaningfully different. We match the certification to the concern — NSF 58 for RO/PFAS, NSF 53 for lead, NSF 401 or P473 for PFAS in pitchers.
