The right water filter
for your water.
Not all water filters remove the same things. Most people buy a Brita and hope for the best. Pollution Profile analyzes the actual violation history and contaminant levels of your specific water system and tells you exactly what filter — if any — you need.
How it works
From your address to the right filter in four steps.
We look up your water system
Enter your address and we pull your public water system's full violation and contaminant history from EPA data.
We identify your specific risks
Not all water is the same. We flag the contaminants that are actually elevated in your supply, not just generic concerns.
We recommend the right filter
Different filters remove different contaminants. We match you to options that address your actual risk profile, at every price point.
You track your protection
Log your filter installation and replacement schedule so your water protection stays up to date.
What we check for
PFAS / Forever Chemicals

Lead
No safe level exists. Enters water through old pipes and fixtures in millions of homes.
Nitrates
Common near agricultural land. Especially dangerous for infants and pregnant women.
Arsenic
A natural contaminant elevated in many regions. A known carcinogen at chronic low doses.
Disinfection Byproducts
Formed when chlorine reacts with organic matter. Associated with bladder cancer and birth defects.
