The AquaOx XL

Description

The AquaOx XL is the largest-capacity whole house water filtration system on the market, purpose-built for homes with 3 or more bathrooms. Engineered and assembled in the USA using NSF-certified parts and media, it delivers a peak flow rate of 37 GPM - enough to keep showers, sinks, laundry, and dishwashers running simultaneously without a drop in pressure. Its 9-layer media bed targets over 300 contaminants, including PFAS, chlorine, chloramines, heavy metals, pesticides, and microplastics, providing better-than-bottled water quality at every tap in your home.

Unlike conventional filter systems that rely on disposable cartridges, the AquaOx XL features an automatic electronic backwashing head that self-cleans every three days - keeping the media bed fresh and efficient for a rated life of 3 million+ gallons, or roughly 10 years of use. Available for both city municipal and private well water supplies, this is the system for homeowners who refuse to compromise on water quality, capacity, or longevity.

FAQ

How long does the filter media last?

The AquaOx XL media bed is rated for 3 million+ gallons of filtration - roughly 10 years for the average household. The automatic backwash cycle keeps the media clean and efficient throughout its life, so there are no annual cartridge replacements or service fees to worry about.

What does the warranty cover?

The AquaOx XL comes with a 10-year warranty covering both the tank and the control valve from the date of purchase. Filter media is consumable and not covered under warranty. Wear items such as seals and O-rings are also excluded. A 1-year money-back guarantee is included as well.

Do I need a plumber to install the AquaOx XL?

Due to the system's size, weight (~175 lbs), and higher flow capacity, AquaOx strongly recommends hiring a licensed professional plumber for installation. Most installs take 2 to 4 hours and cost between $300 and $800 depending on your location and plumbing setup. The unit connects after your main water shutoff and pressure regulator, with a 3/4" drain line for backwash.

Will the AquaOx XL reduce my water pressure?

Any whole-house filter adds some resistance to flow, but the AquaOx XL's 37 GPM peak flow rate is specifically designed to handle the simultaneous demand of homes with 3 or more bathrooms without noticeable pressure drops. For best results, confirm your incoming pressure and household demand with your plumber during installation.

Does it work with well water?

Yes. Well water setups include a heavy-duty 30 GPM backwashable stainless steel pre-sediment filter to protect the main media bed from sand and grit. For wells with a rotten-egg sulfur smell, AquaOx recommends pairing with their RE Edition upstream. For iron staining, pair with the FE Edition. For bacterial concerns, a UV sterilizer can be added.

How is the AquaOx XL different from a fridge filter or water pitcher?

A fridge filter or pitcher only treats a single tap. The AquaOx XL treats every tap, every shower, your washing machine, dishwasher, and ice maker - simultaneously. It also eliminates the ongoing cost of replacement cartridges every few months, making it a more economical and comprehensive long-term solution for whole-home water quality.

How often does the system backwash and how much water does it use?

The AquaOx XL automatically backwashes approximately every 3 days. Each cycle takes about 20 minutes and uses 40-50 gallons of water. No manual involvement is required - the electronic backwashing head handles the entire process on a set schedule to keep the media bed clean and performing at full efficiency.
