  • Filtration type: Choose carbon block or multi‑stage filters. They trap chlorine, lead, and rust. Simple filters are easy to replace.

  • Certification: Look for NSF or ANSI marks. Certified filters meet strict safety tests. This gives peace of mind.

  • Lifespan: Check how many gallons or months a filter lasts. Longer life means fewer trips to the store. Most home filters last 2–6 months.
