Not sure what’s in your water?

Two minutes here can save you buying the wrong filter.

City water

Read your water quality report

Well water

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.

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
