About NSF-44 Certification

All filters listed on this page have been independently tested and certified by NSF International or WQA to meet the requirements of NSF/ANSI Standard 44. This certification ensures that these filters have been rigorously tested for their ability to reduce specific contaminants as claimed by manufacturers.

We recommend choosing filters based on your specific water quality concerns. You can check your local water quality report or test results to identify which contaminants are present in your water supply, then select filters certified to remove those specific contaminants.
