Visit your city's water quality page on our site to see what contaminants are present in your tap water. This will help you choose a filter that targets your specific concerns.
Whole-house systems cost more upfront but provide comprehensive protection. Countertop and pitcher filters are more affordable but only filter water at one point.
NSF International independently tests and certifies water filters. Look for NSF/ANSI standards 42, 53, and 401 for removal of specific contaminants.
Consider filter replacement costs. Some systems have expensive annual filter replacements that can add up over time.
