FAQ Section
1. How often should I replace a water filter?
Replacement depends on filter type. Pitchers and faucet-mounted filters last 2–3 months, while countertop or under-sink systems last 6–12 months.
2. Are discounted water filters reliable?
Yes, as long as the filter is NSF/ANSI certified and purchased from reputable retailers, discounted filters can still provide reliable water purification.
3. Can one filter supply water for an entire house?
Most single filters are designed for drinking water points only, not whole-house use. Whole-house filters require specialized systems.
