NSF/ANSI 53 and 58 are the certifications that matter for PFAS — anything else is marketing. Reverse osmosis systems reliably hit non-detect levels; activated-carbon pitchers reduce but don't eliminate. Pick based on whether you rent (pitcher) or own (under-sink).
Independently tested to remove 99%+ of PFOA/PFOS without a plumber. Sits on the counter, runs off a wall outlet. The simplest serious answer for renters and condos.
Best for: Renters, condos, anyone who can't drill into cabinets
Check current price →The pitcher with the strongest independent PFAS removal data — claims 99%+ removal of PFOA/PFOS on third-party test reports. Slower pour than Brita, but the chemistry is real.
Best for: Single person or couple, budget option, no installation
Check current price →Five-stage reverse osmosis system that mounts under the sink with its own dedicated faucet. NSF-certified components. Plumber install or a competent weekend project.
Best for: Homeowners cooking and drinking from tap daily
Check current price →For severe contamination (well water, known plume, or a UCMR 5 utility exceeding MCL). Treats every tap, shower, and ice maker. Sized by household and water profile.
Best for: Whole-house, well water, documented contamination
Check current price →If you're on a small water system, a private well, or your utility didn't appear in UCMR 5, a lab test is the only way to know. NSF-certified labs cost $200–$500 and run the same gear EPA uses.
Mail-in kit analyzed in an EPA-method lab. Tests the same 29 PFAS compounds as UCMR 5 down to single-digit parts per trillion. The most credible consumer option.
Best for: Anyone serious about a baseline reading
Check current price →Cheaper general-purpose kit covering bacteria, lead, nitrates, and basic metals. Doesn't cover PFAS — pair with the Tap Score for full picture.
Best for: First-pass well-water screen
Check current price →Radon is the #1 leading cause of lung cancer in non-smokers and is invisible in every federal database we surface. EPA recommends testing every home below the third floor every 2 years.
Battery-powered digital monitor that gives 1-day, 7-day, and long-term averages on a screen. Reusable for life of the batteries. The standard non-pro option.
Best for: Anyone buying a house with a basement or crawl space
Check current price →$15 mail-in kit if you only need a single point-in-time reading. Mail the canister to the lab, get a PDF in ~10 days.
Best for: Pre-inspection screen on one address
Check current price →Outdoor AQI doesn't tell you what's actually in your living room. A monitor catches gas-stove NO₂, wildfire smoke infiltration, and VOC spikes from new furniture or paint.
Tracks PM2.5, CO₂, VOCs, humidity, temperature, and radon in one wall-mounted unit. App + web dashboard. Best all-rounder.
Best for: One device that covers everything except outdoor pollen
Check current price →Cheap PM2.5 + formaldehyde monitor for a single room. Useful for spot-checking a kid's bedroom or evaluating a stove or workshop area.
Best for: Add-on for specific rooms, low budget
Check current price →Run an address-level environmental report — it identifies your water utility, PFAS risk, flood zone, and Superfund proximity in one place for $9.99.
