    Frequently asked questions

    How do I choose the best water filter?
    Start with what you want to reduce: taste, chlorine, lead, PFAS, sediment, or other contaminants. Then compare certifications, filter life, flow rate, installation, and ongoing costs.
    Are water filter pitchers enough?
    Pitchers are convenient for taste and simple filtering, but they hold limited water and need frequent refills. Under-sink or faucet filters are better for higher daily use.
    What certifications should I look for?
    Look for filters tested to relevant NSF or ANSI standards for the contaminants you care about. A broad claim is less useful than a specific certified reduction.
    How often should I replace water filters?
    Replace filters on schedule or when flow slows, taste changes, or the indicator says so. Using a filter too long can reduce performance and convenience.
