Specs & the full story

Introducing our flagship whole house filter—The AquaOx. Engineered to transform your water into a pristine, bottle-quality supply at every tap, this advanced backwashing system handles everything from industrial byproducts and volatile organic compounds (VOCs) to heavy metals and treatment byproducts. Whether you rely on city water or a private well, you can trust AquaOx to provide consistently pure, great-tasting water for 10+ years, with minimal maintenance and a 10-year warranty.

Built in the USA with premium NSF certified components and cutting-edge technology, the AquaOx is designed to serve up to 4 bathrooms (or 15 GPM) without any loss in pressure. It automatically backwashes every few days via an AquaOx Electronic Backwashing Head, so your filter media always stays fresh and effective. One purchase, one installation, one system—for a lifetime of worry-free water.

Filter Media Overview

  • Catalytic Carbon: Targets chlorine, chloramines, and VOCs. Excellent against pesticides, herbicides, and certain pharmaceuticals.

Installation & Maintenance

Setting up your AquaOx is straightforward, but we strongly recommend always hiring a licensed professional plumber to ensure proper connections. The system is installed after your main water shutoff and pressure regulator, then the backwash drain is connected, and the unit is plugged into a 110V outlet. Once filled, the AquaOx automatically flushes out trapped air and media fines during its initial backwash cycle. You MUST manually backwash the unit after install. From there, the system backwashes every few days—no manual intervention required.

For well water, a pre-sediment filter is included to capture large particles before entering the main filter. Simply clean this sediment filter periodically based on water quality. City water customers can just relax and enjoy thorough, worry-free filtration.

Experience The AquaOx—our best-in-class whole house filter that guarantees bottle-quality water from every tap. Breathe easier knowing you’re protected from a wide spectrum of contaminants while enjoying better-tasting, pure water for decades.

Questions

The AquaOx, specifically

The questions we hear most about this exact product.

How long does the media last?

The AquaOx is rated for 2 million+ gallons of filtration, roughly 10 years for the average household. The system self-cleans on a backwash cycle so no annual cartridge swaps.

What does the warranty cover?

10 years, end to end. Both the tank and the control valve are covered for 10 years from the date of purchase. Media is consumable and not covered, and wear items (seals, O-rings, etc.) are excluded.

Do I need a plumber to install it?

Most customers hire a licensed plumber. It takes 2 to 4 hours and runs roughly $300 to $800 depending on your area. You can DIY if you are comfortable cutting into your main water line and routing a drain line.

Will it slow my water pressure?

No. The AquaOx is rated for 15 GPM peak flow, enough for up to 4 bathrooms running at once with no noticeable pressure drop.

Does it work on well water?

Yes. Well installs add a 7th phase, a pre-sediment filter ahead of the tank, so sand and grit do not load up the media bed. For wells with rotten-egg sulfur smell, pair with the RE Edition upstream. For wells with iron staining, pair with the FE Edition upstream. For bacteria, add the UV sterilizer.

How does it compare to a fridge filter or pitcher?

A fridge filter or pitcher treats one tap. The AquaOx treats every tap, every shower, your washing machine, dishwasher, and ice maker. Plus you stop buying replacement cartridges every six months.

Ready to stop drinking your tap water?

The AquaOx. Ships within 10 business days. 0% APR financing available.
