NSF/ANSI standards are the benchmark for water filtration. Products are tested and certified against them by accredited independent laboratories.
Certifies that the filter reduces chlorine, taste, odor, and other aesthetic contaminants that affect how your drinking water looks, smells, and tastes. Every sip, fresher.
The most critical certification — certifies reduction of health-threatening contaminants including lead, volatile organic compounds (VOCs), chromium, and cysts like Cryptosporidium and Giardia.
Certifies that every part of the filter touching your water is lead-free by law — weighted lead content at or below 0.25%. Safety built into the hardware itself, not just the filtration media.
Certifies reduction of trace pharmaceuticals, herbicides, pesticides, BPA, and flame retardants — 15 modern contaminants that older certification standards didn't even test for. Critical for modern water safety.
Certifies reduction of PFOA and PFOS — two of the most persistent "forever chemicals" in the PFAS family, linked to serious health concerns and found in water supplies nationwide.
Canada's national standard for drinking water treatment systems — independently verified for contaminant reduction, material safety, and structural integrity.
