Search for a reverse osmosis company and most of what you find is selling a box. This site was built for the other half of the question: who comes to the house, looks at the water and the sink, fits a system that suits both, and can come back for upkeep.

What this site is
Reverse Osmosis Company is an independent referral service, not an installer or plumber. When you send the form, your details go to an independent local water treatment pro who can contact you and prepare a quote. The site does not install, service or repair anything, sells no systems, filters or membranes, and recommends no brand.
Requests come from anywhere in the United States. The ZIP code you give is how your request is passed to a pro who works in your area. No pro is named on this site, and the pro who can contact you is independent of it.
What it costs you
Nothing. Sending the form is free, and you never have to buy. Any price is in the quote a pro gives you, and that quote is yours to accept or turn down.
What the guides are built on
The guides on this site use public sources and name them where they are used:
- The EPA’s WaterSense program, for how reverse osmosis works and how much water RO systems send to the drain.
- The EPA’s secondary drinking water standards, for taste, color and staining guidelines.
- The EPA’s PFAS and private well pages, and the CDC’s well testing guidance.
- The EPA’s pages on certified water filters, for the standards to look for, such as NSF/ANSI 58 for reverse osmosis systems.
- The Texas Commission on Environmental Quality, for advice on choosing home water treatment and an example of state licensing.
Rules and guidance change. Where a page relies on a dated rule, such as the EPA’s PFAS proposals, it gives the date.
What it will not tell you
This site makes no health claims and does not say whether your water is safe. For health questions, ask your doctor. For what is in your water, read your utility’s yearly report or test your well with a certified laboratory. It makes no promise about any pro’s work, price or timing, which is why the pages on RO installation and reverse osmosis near me set out how to check a pro yourself.
Who the pros are
The pros your request goes to are independent water treatment pros and plumbers who work in their own areas. They are not employed by this site, and this site does not vouch for their work. Check any pro yourself: ask what license your state requires for water treatment work, whether your city needs a permit, and for the quote in writing.


How to use it
