Frequently Asked Questions
How were these filters selected?
Filter information for this ZIP is informed by EPA SDWIS compliance records from the past 5 years; test your tap water or consult your utility for contaminant results. Filter types may vary by location; verify a product's certification for each contaminant of concern.
Do I need a whole-house or under-sink filter?
It depends on the contaminant type and your budget. Under-sink reverse osmosis systems can reduce drinking water contaminants such as lead, nitrates, and some PFAS when certified for those reductions; prices vary by model. Whole-house systems ($800–$2,000+) treat water where it enters your home, including water for showers and appliances; check each product's certification for the sediment, chlorine, or hardness issue you want to address.
How often should I replace filter cartridges?
Replace filter cartridges according to the manufacturer's schedule, which varies with water use and water quality. Check your filter manufacturer's guidelines and replace on schedule to maintain effectiveness.
