  • Performance: While the unit may state it is NSF certified, what is the size of the smallest particles removed from your water? We evaluate this in our brand comparison review.
  • Satisfaction: Learn which brands are favorites with consumers just like you.
  • Reliability: Before deciding on which water filter to purchase, it is critical to understand the manufacturer's warranty. Not only the length of the warranty, but what it includes.
