Look up your water utility’s record first, then pick a filter for what’s actually in it.
Read your water quality report
Your utility must publish one every year. What it lists, how to find yours, and why “legal” isn’t always the same as safe.
Test your well before you buy
Bacteria, metals, nitrate and PFAS can all turn up in well water. What to test for, and where.
Lead from your own pipes
Lead rarely comes from the source water. It leaches from service lines, solder and fixtures. How to check, and which filters are certified for it.
Or browse by filter type
Each ranked on certified reduction, running cost and ease of use.
No brand can pay for a ranking.
We earn a commission when you buy through our links, but a filter’s place comes only from our published scoring: certifications, lab data, running cost, ease of use and flow. If a $40 pitcher beats a $400 system on the data, the pitcher wins. How we rank
