I used a Brita Elite filter every day for my family. The water tasted fresh and crisp without any odd smells. It saved us money on store-bought bottles.
-
NSF Certification: Look for filters certified by NSF to ensure they remove contaminants reliably. This means independent testing for safety. Choose certified options for peace of mind.
-
Filtration Type: Pitcher filters like Brita or Waterdrop are easy to use and store in the fridge. Under-sink systems such as iSpring or Waterdrop 10UA connect directly for constant flow. Countertop models like SimPure or Bluevua need no plumbing but take up space.
