About the lab
A five-figure decision deserves a second opinion.
Most people meet water treatment the same way: a dealer walks through the house, tests the water, and leaves a quote somewhere between $5,000 and $10,000. The Home Water Lab exists for the week that follows, the week you spend trying to work out what any of it is worth.
The Home Water Lab started as a YouTube channel with one rule: no hype, just the numbers that decide whether a softener or filter is worth the money. This site is that channel’s written lab notebook, the spec sheets, the dated prices and the 10-year math behind every video, in a form you can search, print and take to a dealer.
We cover residential water treatment in the United States, and nothing else: water softeners, salt-free conditioners, whole-house filters, well water systems and reverse osmosis. That narrow scope is deliberate. It is what lets us read the manuals in full rather than skim a retail listing.
Rankings come out of the spreadsheet, not out of a deal: the specs, the dated prices and the ten-year math decide, and plenty of the systems we recommend bring the lab nothing at all.
Who does what
Two jobs, two names, kept separate on purpose, the way specialist publications have always done it.
Home Water Lab Team
Research and writing
The team reads the manufacturer documentation, records prices with the date they were seen, checks certification listings and builds the cost-of-ownership models. Every article on this site is written here.
How the team worksRay Calloway
Water treatment expert · Technical review
Ray Calloway is a water treatment expert. He does not write the articles, he reviews the technical analysis published here: sizing math, spec interpretation, certification claims and whether an installation described on the page is realistic in a real house.
What Ray reviewsAn article says “Reviewed by Ray Calloway” only when that review has actually taken place. Where it is absent, the piece stands on the team’s research alone, and says so by staying silent.
What we hold ourselves to
Numbers over adjectives
Every claim traces back to a manufacturer spec sheet or a certification listing. If we can't source a number, we don't print it.
Prices with a date on them
Water treatment prices move constantly. Every price on this site carries the date we last checked it, so you know exactly how fresh it is.
The 10-year view
The sticker price is half the story. We project salt, filters, membranes and power over a decade, because that's what you'll actually pay.
The limits matter as much as the method: we do not run a testing laboratory, and we do not accept free equipment in exchange for coverage. Our methodology page sets out exactly what we verify, how, and what we deliberately don’t claim.
Found an error? Tell us.
Specs get revised, models get discontinued and prices move. If a number on this site is wrong or out of date, the fastest way to reach us today is a comment on the Home Water Lab channel, we read them all. Corrections are made on the page and the update date is stamped, so you can see what changed and when.
