Air Scrubber Plus incorporates NASA ethylene-scrubbing technology. The device is installed into home ventilation systems, which disseminate the product’s “friendly cleaners” that kill pathogens in the air and on surfaces.

In addition to converting ethylene into harmless byproducts, the scrubber was also found to kill pathogens. As a result, a line of air purification systems utilizing the technology is now on the market that not only keeps food fresh in warehouses and markets but also helps decontaminate the air (Spinoff 2002, 2009). Consumer versions of the system for the home also followed (Spinoff 2013).

Another company, Electrolux (now Dallas-based Aerus Holdings), of vacuum cleaner fame, also furthered the technology but took it in a slightly different direction. Rather than cleaning passing air, the company’s family of air purification products does something unique: it takes the circulated air generated by a building’s heating and cooling ventilation (HVAC) system and produces molecules that disseminate into the environment, killing pathogens in the air and on surfaces.

Called ActivePure Technology, and commercially available since 2013 as the Air Scrubber Plus, the key to its function is a proprietary blend of reactive metals added to the original titanium dioxide coating. When exposed to ultraviolet light, these metals mix with the surrounding air and humidity to produce charged clusters of hydrogen and oxygen such as hydrogen peroxide, hydroxyls, and superoxide ions, which are antimicrobial agents also found in nature. “We call them friendly cleaners,” says Air Scrubber Plus executive director Tom Lozano. “They go out and reduce contaminants throughout an entire home.”

What’s more, these “friendly cleaners” are also mostly negatively charged ions. The majority of particles around the house are positive, so these ions pull these particles from the air, greatly reducing loose dust and pollen. The Air Scrubber Plus is also available in models equipped with ozone, which greatly enhances the device’s ability to combat strong odors from pets and cigarette smoke.
