In-duct Air Purifier

Restore by Stanley Steemer®™, the solution for indoor air pollution

Harmful chemicals, mold, germs, allergens, and other contaminants can be present in our air whether we know it or not. Sadly, air filters aren’t enough to remove the majority of pollutants that circulate in your home. Restore is an in-duct air purifier that is proven to detoxify air and get rid of common sources of indoor air pollution within hours. Using a unique combination of UV-C light and activated carbon cells, our in-duct air purifier reduces air pollutants throughout the entire home. The UV-C light also keeps AC coils and blowers free of efficiency-robbing biological growth such as mold and bacteria.

Indoor Air Pollution & Your Home

Indoor air pollution is often two to five times worse than outdoor air pollution. Regular filters only remove particulates which make up a mere one-third of indoor airborne contaminants. Our in-duct air purifier addresses the other two-thirds of contaminants, both biological and chemical, for complete whole-home air treatment. Restore is especially effective against Volatile Organic Compounds (VOCs), which are the source of nearly all bad smells and can even be toxic, such as formaldehyde. This leaves you with cleaner, healthier and safer indoor air.

How Restore™ Works

Restore is designed to sterilize and inactivate mold, fungi, viruses and other microorganisms in the airstream and on internal surfaces of HVAC air handlers. It’s installed in the ductwork of the central air system and the technology is based on a process called photocatalytic oxidation. Germicidal UV-C light reacts with titanium dioxide-infused carbon cells to neutralize contaminants. In other words, these cells attract and hold odors and microbes which are then eliminated by exposure to UV light. The only thing left behind is harmless water vapor and CO2. This process also keeps the carbon cells clean so the system is virtually maintenance-free. The final result is safer, cleaner, odor-free air.

Proven Safe and Effective

In multiple laboratory tests, Restore has proven to be safe and effective. It has been validated as ozone-free by UL Labs, certified by CARB & ETL, and has won the prestigious AHR Innovation Award for indoor air quality.

Test results from Airmid Healthgroup, an accredited IAQ testing laboratory, have proven the effectiveness of this technology. The tests verified that the air purifier has the capability to both sterilize microorganisms and reduce volatile organic compounds (VOCs). Restore titanium-dioxide infused activated carbon cells were shown to be “capable of reducing high concentrations” of VOCs commonly found in homes and commercial buildings, including hospitals, hotels, offices and schools.
