Technology Born in Healthcare
Made for Every Industry

Whether you’re looking to add an extra layer of protection to your home or place of business, we have a solution for you. Our primary solution, CASPR In-Duct, is installed in the supply of your HVAC duct where it is able to provide building-wide coverage.

Like all CASPR Group solutions, the CASPR In-Duct units are easily installed, require no operator or chemicals, are low maintenance, and run continuously.

Easy Installation

Continuous Coverage

No Chemicals

Low Maintenance


CASPR In-Duct units are installed in your HVAC supply where they utilize ambient air to create active molecules, including hydrogen peroxide. These molecules then exit your HVAC ducts, circulate the targeted area, and land on all surfaces providing continuous micro-burden reductions. CASPR is up to 99.96% effective against molds, bacteria, and viruses, and has the added benefit of reducing odors and VOCs. Once these bad pathogens are neutralized at the cellular level, the oxidizing molecules created by CASPR then revert back to their original state (hydrogen and oxygen).

CASPR In-Duct solutions come in a variety of sizes; each is designed to target a specific amount of square footage with the appropriate Parts Per Million (PPM) of active molecules. The levels generated are effective against harmful pathogens but safe for people, pets, and plants. Depending on the solution, the device will cover 400, 1000, 2500, or 5000 square feet. To learn what size is best for you, our team of experts review your HVAC plans and develop an installation plan. Installation can be completed by any licensed HVAC professional, and is a quick and easy process.

CASPR Pro: In-Duct Unit

How It Works

CASPR Group utilizes a proprietary Natural Catalytic Converter (NCC). The NCC includes a multi-wavelength bulb and coated mixed metal matrix which work together with your ambient air to turn hydrogen and oxygen molecules into low but stable levels of Hydrogen Peroxide. CASPR requires a minimum of 5% humidity and air flow to generate these molecules. CASPR Group’s solutions do not produce any ozone. If you turn off your HVAC, the CASPR In-Duct units will remain on but unable to produce any molecules. We recommend turning it back on a few hours before the space is occupied again to ensure the molecules have enough time to be generated and circulated.

Hear From Our Customers

Mark Baranowski, owner of the Northpark Lounge, installed the CASPR In-Duct into all of his restaurants in a concerted effort to go above and beyond providing clean air for his customers. Hear about the reason why he made this investment in the following video.

“It is going to eliminate over 99% of all bacteria, mold and viruses that are within this building.”
