The AquaOx difference
One system. Every tap. Done right.
AquaOx began with a single goal: protect families from what's really in their water — without the upsells, the rented tanks, or the maintenance treadmill. One whole-house system, built to last, backed for a decade.
300+
contaminants reduced
Chlorine, lead, PFAS, sediment, hardness, taste & odor — at every tap.
6
media layers
Built from NSF-certified parts & media in a single auto-backwashing tank.
10-yr
warranty
End-to-end coverage on the tank and head. Veteran-founded, made in the USA.
5,000+
homes protected
Trusted across the USA since the company began with one discolored-water problem.
Why AquaOx
Ultimate purity. Ultimate protection.
The difference is inside. AquaOx packs more premium filtration media into a single tank than any other system on the market, so it filters more contaminants and lasts longer.
Ultimate purity
6 layers of premium filtration media
KDF 85 · Garnet · Centaur Catalytic Carbon · Activated Coconut Shell Carbon · Filter-AG. 3× the surface contact time of competitor systems.
Patented technology
Vortech distribution plates
Double-Vortech design eliminates gravel beds, increases media efficiency, and significantly reduces water use during regeneration cycles.
Built to last
Lasts 2× longer than carbon competitors
Filter media rated for 10+ years vs. the ~5-year carbon-only systems most competitors sell. In practice, many AquaOx systems we installed 15+ years ago are still running strong.
How the AquaOx compares
Side by side with two of the most-searched whole-house systems, using each manufacturer's own published numbers.

Common questions
What does AquaOx filter from my water?
Chlorine, chloramines, lead, mercury, arsenic, iron, sediment, herbicides, pesticides, VOCs, industrial byproducts. Over 300 contaminants in total. It also reduces fluoride — up to about 40% in independent lab testing — though for fully fluoride-free drinking water we recommend pairing it with our under-sink RO at the kitchen tap.
Do I still need an under-sink RO for drinking water?
It depends on what you want at the kitchen tap. The AquaOx filters 300+ contaminants whole-house, great for showering, laundry, dishes, and drinking. It also reduces fluoride (up to about 40% in independent lab testing), but if you want it fully removed, we recommend pairing AquaOx with our under-sink reverse osmosis at the kitchen tap — RO is the best at-home way to take fluoride all the way down.
What size do I need: Regular or XL?
The standard AquaOx is great for most homes up to 4 bathrooms. For larger homes, choose the XL. That said, the XL has the most filter media of any system on the market. If you want maximum protection and the longest possible service life regardless of home size, the XL is the move.
Do I also need a water softener?
AquaOx is a purifier. It filters contaminants but leaves healthy minerals like calcium and magnesium in your water. If you have hard water (common with well water and in much of the Southwest), you may still want a softener to prevent scale on fixtures, water heaters, and tankless heaters. The AquaOx goes first, the softener after. Not sure if your water is hard? Send us your water report and we will tell you.
Where do I install it?
Wherever your main water line enters your home, most commonly the garage. It can also go in a basement, utility room, or even buried in a crawl space (your plumber digs out a level pad). In warm, non-freezing climates like Florida, outside is fine too. Do not install outside in any climate where water can freeze.
How long does installation take?
A licensed plumber typically installs The AquaOx in 2–4 hours. AquaOx is direct-to-consumer: any licensed plumber can do it. There is no proprietary tooling or certified installer required. The install is three connections: inlet, outlet, and a small drain line.
Will this work for well water?
Yes. AquaOx is built for both city and well water. If you have specific concerns (heavy iron, hydrogen sulfide / rotten egg smell, bacteria), we offer specialty systems and add-ons. Take the quiz or call us at (803) 369-6956.
Will it protect my tankless water heater?
Yes, and we recommend it. Chlorine and chloramines degrade tankless heat exchangers over time; AquaOx filters them. If your water is also hard, pair AquaOx with a softener: tankless manufacturers will void warranties on units that scale up from hard water.
How long does the filter media last?
AquaOx filter media is rated for 10+ years. In practice, many AquaOx systems we installed 15+ years ago are still running strong. The system self-backwashes every 3 days to keep media performing, no manual maintenance required.
What's the warranty?
10-year parts & labor warranty on every AquaOx system. We stand behind every system we ship.
Do you offer financing?
Yes. Affirm offers 0% APR financing on AquaOx systems. The flagship works out to about $104/month over 24 months. Apply at checkout in seconds.
