Radon in your water is more than just an unseen contaminant—it emits radioactive gas that enters your home, posing a serious health risk. When radon gas is inhaled, it becomes one of the leading causes of lung cancer, second only to smoking. Many homeowners don’t realize that their water source, especially from granite-rich well regions, can be a hidden source of this dangerous gas. Addressing radon before it escapes into your living space is essential for protecting your family’s health.

The system that solves it

The radon-reduction system designed for whole-house protection is a robust and efficient solution engineered to reduce radon levels in your water before it off-gasses indoors. At the heart of the system is a catalytic carbon filter that utilizes a large granular-activated-carbon (GAC) bed, ensuring extensive contact time for radon adsorption. This system is built with convenience and reliability in mind, featuring a non-electric upflow or metered backwashing head that keeps the carbon media clean without the complexity of electricity. Unlike systems requiring frequent cartridge changes, this design eliminates the need for cartridge replacement by using a deep, high-capacity carbon bed. Additionally, it includes a bypass valve, allowing easy service without disrupting your water supply.

• Whole-house catalytic carbon filtration
• Non-electric upflow or metered backwashing head options
• Deep carbon bed for extended media life and performance
• No cartridges to replace, reducing maintenance effort
• Convenient bypass valve for uninterrupted service

What it does for your home

This radon-reduction system offers comprehensive protection by acting on your water supply before radon gas can escape into your home’s air. It’s an investment in the health of your household, particularly in areas prone to radon contamination from natural underground sources. Here are the key benefits you can expect:

• Significantly reduces radon concentrations in your water
• Prevents radon off-gassing, lowering indoor air contamination
• Protects your entire home, ensuring safe water from every tap
• Minimizes lung cancer risk associated with inhaled radon
• Operates with low maintenance thanks to long-lasting carbon media
• Especially critical for homes in granite well regions where radon levels tend to be higher

By reducing radon early in the water system, this system contributes to healthier indoor air quality and offers peace of mind for you and your family.

Why it works

The effectiveness of the radon-reduction system lies in its large granular-activated-carbon contact bed. Radon is a radioactive gas that can dissolve in water and then escape as gas when the water is used inside your home. The system forces water to flow through a deep bed of specialized activated carbon granules, which capture radon particles through adsorption. Because the carbon bed is sized to provide sufficient dwell time—meaning the water remains in contact with the media long enough—the radon is absorbed before it reaches your taps. This physical process reduces the concentration of radon in the water, significantly lowering the amount of gas released into your home’s air.

Sizing it right

Choosing the proper size for your radon-reduction system depends on your household water usage and flow rate. A system sized too small may not effectively reduce radon, while an oversized system can be an unnecessary expense. Typically, the system should match your average daily water flow to ensure optimal contact time with the carbon media. We offer free sizing assistance to help you determine the best fit based on your home’s water demand and radon levels. With the right sizing, you can maximize performance and enjoy efficient, reliable radon reduction.

Common questions

Q? How quickly can I expect to see radon levels drop after installing the system?
A Radon reduction begins as soon as water flows through the catalytic carbon filter. Most users notice a significant decrease in radon concentration immediately after installation, with ongoing effectiveness maintained as long as the carbon media is properly serviced.

Q? Does the system require electricity to operate?
A This system is designed to function without electricity by using non-electric upflow or metered backwashing heads. This ensures reliable operation even during power outages and reduces energy costs.

Q? How often do I need to maintain or replace parts of the system?
A The deep granular-activated-carbon bed significantly reduces maintenance frequency, and there are no cartridges to replace in the primary system. Periodic servicing is recommended to backwash and refresh the carbon bed, facilitated by the system’s bypass valve for easy access without interrupting your water supply.
