AiroClean420 AIRO-50XL - Grow Room Air Purifier

No Emissions Air Sanitation System With The AiroClean420XL AIRO-50XL

Completely safe unlike some other air sanitation systems that propel potential hazardous gases or chemicals back into the room thus risking your valuable plants. Powdery mildew removal has been a difficult task for commercial growers and producers for a long time, until now!

AiroClean 420

Developed by NASA engineers, The AiroClean420 works by continuously processing your contaminated air through a patented Bio-Conversion Reactor. This product is a safe alternative for pesticides! and effectively removes naturally occurring pest such as - Powdery Mildew, Gray Mold/Botrytis, Downey Mildew, Blight, Bacteria, Viruses, Allergens, and VOC's. They are mineralized through the AiroClean 420, in result leaving exit air 99.999987% contaminant free! No chemicals or toxic gases, are used or created with this product. The elimination all airborne pathogenic micro-organism and VOC's takes place within the AiroClean420 PCO chamber!


How It Works

Spore and Pathogen-filled air enters through the fan and gets pushed in to reactor bed. The Spores at that point are then immobilized onto Photocatalyst Surfaces (as well as other interior surfaces), are exposed to surface bound radicals and UVGI. For many years, this made in America NASA Developed Air Sanitation Technology has been a significant Preventive Control in helping the Food & Beverage Industries protect their perishable products from costly and harmful contamination. Since then thousands of global companies, across a variety of agricultural markets, have shared positive performance feedback.

Photocatalytic Oxidation (PCO) Process

AiroClean420 AIRO-50XL - Grow Room Air PurifierThe AiroClean420 Air Sanitation System utilizes a patented Bio-Conversion reactor currently used in units around the world. As contaminated air enters the AiroClean420 system, it passes through thousands of rings contained within a sealed reaction chamber. These rings surround an array of proprietary high-intensity PCO lamps, which serve as the unit’s primary source of energy.

As the contaminated air passes over the lamps, they excite the catalyst and form millions of hydroxyl radicals that mineralize mold and fungi such as powdery mildew, pollen, viruses, bacteria, allergens, and VOC’s. Instead of being released as a harmful gas, they are transformed into harmless and green carbon dioxide and water vapor. The result is clean air distributed throughout your facility. There is no ozone produced. No peroxides or oxygen derivatives generated. Only AiroClean420 sanitized air.

Operation cost of the AiroClean420 is minimal and affordable. This system in energy efficient, requiring less than 2 amps and consumes less energy than (2) 100 watt light bulbs, and only requires a yearly replacement for Proprietary High Intensity Energy PCO lamps. AiroClean420 can be quickly and easily retrofitted into most all facilities.


What makes this Photocatalytic Oxidation technology different than others on the market?

Other attempts at using Titanium Dioxide (TiO2) coated materials that claim oxidation or pathogen destruction have proven ineffective because of slow oxidation efficiency. The intended catalysts in these cases are either not photocatalytically active and/or delaminate (or split into thin layers) easily. The patented AiroClean420 technology utilizes a nano particle science to make a titanium oxide membrane that is photocatalytically active, which also binds to the applied surface(s) without delaminating. Nanotechnology comprises technological developments on the nanometer scale, usually 0.1 to 100 nm, or ten thousand times smaller than the width of a human hair.



The new XL model is equipped with a protective filter on the inlet side of the system that helps to keep the unit's catalyst cleaner which results in the unit being even more effective. This protective filter needs to be changed approximately every 6 months.

Size Matters to Stop Powdery Mildew

Powdery mildew and airborne threats thrive in closed grow facilities. In the last couple of years, we’ve helped thousands of growers remove airborne pathogens. Keeping their air and plants clean. Plus, free of emissions, ozone, and environmental worries. Your time and effort are valuable when cultivating high-quality product. We are here to support you and make growing easier. Size doesn’t matter to mold, but size does matter to stop powdery mildew effectively.

Thousands of our AiroClean420 commercial growers have successfully stopped powdery mildew from wiping out their crops with our air purification system.

For commercial growers, our AiroClean420 unit is tried and true when it comes to eliminating powdery mildew and keeping commercial growers compliant. Commercial air purification is important because airborne threats can spread quickly and devastate your product and profits.

Medical patients rely on growers to keep mold and mildew out of their products for health and safety. Organic providers can benefit from AiroClean420 air purification because it eliminates the need for harsh chemicals. Product grown for edibles must also stop the slightest signs of powdery mildew or mold for ingestion safety.
