How to choose a water filter

A good filter choice starts with four things: your water, your goal, your space, and the amount of maintenance you are comfortable doing.

Know what you want to change

Taste and odor, a specific test result, scale, and broad dissolved solids are different problems. They may call for different treatment.

Choose a practical format

Consider pitchers, faucet filters, countertop systems, under sink filters, and whole home equipment based on the job you need done.

Verify product claims

Look for model specific performance data and certification. Broad marketing language is less useful than a named standard tied to a named reduction claim.

Plan for ownership

Check filter prices, replacement intervals, installation requirements, power needs, and available space.
