About TapChecked

TapChecked exists because buying home water treatment is harder than it should be. The products are technical, the claims are slippery — “certified” can mean the whole system, one cartridge, or nothing verifiable at all — and almost every review on the internet quietly earns more when it recommends the expensive option. We built the site we wanted to read before spending our own money.

What we do

We research home water filters, reverse osmosis systems and water softeners, and we check three things on every product we cover. First, the certification: we look up the exact model’s listing in the NSF and IAPMO databases, because a logo on a sales page is not a certification. Second, the evidence: we cite published independent lab data where it exists, and we never dress up a manufacturer’s own claims as test results. Third, the money: we publish the five-year cost of ownership — filters, salt, wasted water, electricity — next to the sticker price, because the cheapest system to buy is often the most expensive one to own.

What we don’t do

• We don’t accept payment for placement, rankings or reviews. No brand can buy a better verdict.
• We don’t publish health claims beyond what certifications and public health agencies support.
• We don’t present spec-sheet research as hands-on testing. When we haven’t tested something ourselves, the page says so.

How the site pays for itself

TapChecked earns money through affiliate links and, in the future, display advertising. If you buy through a link on this site, we may earn a commission at no additional cost to you. That model only works if you trust the recommendations enough to come back — which is exactly why the checking comes first. The full details are on our affiliate disclosure page, and our complete methodology is published at How We Test & Check.
