H2KNOWN

Put your certified filters in front of people who need them

H2Known gives people a plain-English report on their water from their ZIP code or a lab test, then matches them with filters certified to fix what's actually in it, at a price that fits their budget.

Free to be listedEvery product is listed at no cost. We earn a commission on sales, through your affiliate program or ours.
Matched by real water dataYour products show up when they're certified for what's in someone's water, their budget, and whether they want drinking water, whole-home, or both.
You keep the customerYou ship every order yourself, and customers come to your brand for support and replacement filters.
Our standardWe show shoppers exactly what backs up each product: independent certification (NSF, WQA, or IAPMO), third-party lab testing, or manufacturer claims. Certified products are shown first. Brands can't pay to be listed or ranked.

The information above is accurate. I understand H2Known shows each product's certification or testing status honestly, lists certified products first, matches products to people by their water, and may earn commissions on sales.
