What Does It Do?


The Dust Free® Active Air Purifier’s unique combination of technologies target air quality problems at the source, such as dust, dander, volatile organic compounds, allergens, and odors. Installed into the supply plenum of your HVAC system, the Dust Free® Active in-duct air purifier’s environmentally-friendly oxidizers and ionization system safely clean the air in your home.

  • Unique technologies, utilizing UV light and ionization, provide a comprehensive IAQ solution.

  • Reduces particulate matter such as dust and dander by improving the performance of your existing filtration system.The Dust Free® Active's high-output ion brushes charge particles and assist your air filter in capturing particulates.

  • Innovative carbon fiber brushes increase ion production. 

  • Reduces odors and VOC's using the proprietary UV photocatalyst.

How Hydroxyl Ultraviolet Air and Surface Purifiers Work.


Hydroxyl cleaners use UV energy to generate a sanitizing molecule called the hydroxyl radical (or just “hydroxyl”) and other resulting oxidants, which are also sanitizing agents. These chemicals are in the vapor phase and are similar in concentration to the hydroxyls and oxidants which are produced outdoors. Hydroxyls can be formed at different wavelengths beginning with photolysis of water vapor or ozone, but the dominant pathway in hydroxyl cleaners is via the generation of UV light with sufficient energy to break the H-O bond in ambient water molecules:


Hydroxyls are also formed in nature in our lower atmosphere, predominantly by the photolytic decomposition of ozone by UV radiation.  These initiate a series of fast, free radical chain reactions that decompose VOCs and their by-products, keeping air safe to breathe. Hydroxyls and the secondary organic oxidants that are formed by them can also kill bacteria, viruses and mold by causing the thin, delicate cell walls to rupture through reaction with the lipids and proteins in them.

Atmospheric hydroxyls do not exist naturally indoors at levels high enough to sanitize. Hydroxyls formed outdoors react so fast following their creation (within a fraction of a second) that they do not have an opportunity to be transported indoors. Hydroxyl cleansing systems work by irradiating the water vapor and other gases in air as it is circulated through chambers equipped with UV lamps, generating hydroxyls and other oxidants. The hydroxyls, and the resulting organic oxygenated species they form, react with and decompose mid to high ppb levels of VOCs and kill a broad range of bacteria, viruses and mold in air and on surfaces. The organic oxidants are themselves very powerful sanitizing and deodorizing chemicals. They are more stable and react less quickly than hydroxyls, so they can circulate throughout the treatment area to complete the purification process.
