Frequently asked questions

Yes. The water report and membership are both free. Products you choose to buy are priced by each company.

On the home page you enter your ZIP code, where your water comes from (city or well), whether you own or rent, and what you drink. Your report uses public records for your water system, like EWG's Tap Water Database and U.S. EPA records, and explains what was found in plain English.

Your report is emailed to you, usually within a minute. If your water company's full data is still being loaded, your complete breakdown follows by email within 24 hours. Check your spam or promotions folder too.

Public records describe your water system, not the water at your specific tap. A home water test is the most accurate way to know your own water. Your report recommends a test that fits your water.

Private wells aren't covered by public records, so a home water test matters even more. Choose "Well water" and we'll point you to a test that fits.

Your full water report by email, a saved account with your reports and picks, a profile, and badges like Know my water, Tested my tap, Filtered my water, and Hydrogen water.

Products are matched to your water. Independently certified products (NSF, WQA, or IAPMO) are shown first, and only products that ship to your country are shown.

• Proof: independent certification for what the product claims.
• Fit for your water: how well it covers what's in your water.
• Budget: how it fits what you said you'd spend.

We may earn from partner links. Our recommendations are based on your water, never on commissions.

Some products show a Financing badge. Multipure offers PayPal and Sezzle at checkout. For the Enagic K8, any financing options are shown on Enagic's page.

Tap Shop on the product and we'll email you step-by-step ordering instructions. Filter auto-ship is set up after checkout.

The Enagic K8 is a countertop water ionizer. It isn't a contaminant filter. It makes hydrogen-rich water from the water it's fed, so a good drinking-water filter before it is recommended.

K8 buttons open a short H2Known page first. In the United States, tap Proceed on Enagic's page to get to the K8 and order. Outside the United States, choose your country on Enagic's page and follow its steps. You'll see the price and any financing options there.

Apply free at h2known.com/affiliates. We review every application, usually within a few business days, and you'll get an email when you're approved. Every affiliate also has a free member account with the same email.

Totally fine. Add your company IDs and order links in your back office under Company links, so the people you send buy through you. You can also earn from other options that fit different people better.

You earn a share of each commission. Sales levels: Bronze (1st sale), Silver (5), Gold (10), Platinum (20 sales, earns 75%), and Black (50 sales, earns 80%).

New member 2 points, new affiliate 3, installer 4, water company 5. Each person counts once, and your own accounts don't count. Open My points breakdown in your back office to see exactly who counts.

Your badges for members, affiliates, water companies, and installers you bring in level up: Drop (1–4), Ripple (5–9), Stream (10–14), River (15–19), and Ocean (20+). There's also a fifth, golden White Lion Ocean: $100 given to the White Lion Sanctuary through you, your members, and your affiliates. Each Ocean earns a gift, and Ocean on all five earns our major gift.

Give any amount at h2known.com/whitelions. Every dollar is passed on to the Global White Lion Protection Trust, and you'll earn the White Lion badge. Gifts through H2Known aren't tax-deductible for you; for a tax receipt, give directly through CoreLight or whitelions.org.

In your back office under Marketing: a launch post and 6 story slides, with your photo, without a photo, or with a blank circle.

Apply free at h2known.com/partners. You'll list your products with price, link, and proof (certificates or spec sheets), or mark "no certificates yet." You'll also add your business registration, insurance, main contact, hours, and where you ship.

Yes. You can use H2Known Checkout with a commission you choose.

Installers and plumbers can join free at h2known.com/installers. Proof of insurance is required. You set your service ZIP and radius to get local install jobs.

If an affiliate referred you, they see only your name, photo, and badges, never your email, your answers, or your water results.

Only if you opt in, and we hope you will: every opted-in result helps build a real picture of water in homes around the world, so each area can be served better. Anonymized results (no name, email, or street address; your ZIP code is kept so results match the right water system) may be included in H2Known water research. Change your choice anytime in your account. Read more.
