Improve Cannabis Crop Yield Substantially

Join the fight! Wipe out powdery mildew!

Airborne powdery mildew, fungal diseases, mold, blights and bacteria are ruining your cannabis plants and profits.

Airoclean 420 by Sterilumen dramatically improves your crop yield by purifying the air in your grow environment. With our Patented Photocatalytic Oxidation technology (PCO), Airoclean 420 traps and destroys all airborne powdery mildew and other fungal diseases.

Airoclean 420 is far more effective than HEPA filters, which use a “screen door” design circulating harmful pathogens and contaminants back into the air.



Eliminate Powdery Mildew Spores

Our state-of-the-art air purification system was used on NASA’s International Space Station!
No emissions. No ozone. Absolutely safe.
Just mount, plug in and use. Easy.

How Airoclean 420 Works

Airoclean 420 uses a patented Bio-Conversion Reactor to kill powdery mildew, bacteria and pathogens. As contaminated air enters the system, it passes through rings contained within a sealed reaction chamber. The rings surround an array of proprietary high-intensity Photocatalytic Oxidation (PCO) lamps, which serve as the unit’s primary energy source. As contaminated air passes over the lamps, they excite the catalyst and form millions of hydroxyl radicals, mineralizing powdery mildew, pollen, viruses, bacteria, allergens, and VOCs. No ozone. No emissions. No chemicals are used.



Customer Testimonials

The Airoclean 420 Photocatalytic Oxidation (PCO) scrubbers are the best plug-and-play units I have come across in my 20+ years in the business. I have successfully used them at scale in several remodels and operational turnarounds to combat severe, large-scale powdery mildew infestations. They eliminate the problem every time without fail, and with continued use, they offer insurance against re-infestation.

Cody Henderson, Head of facilities, Dragonfly

We have 300,000+ sq. ft. under roof. Our total flower canopy is expanded further because we utilize multi-tier racks in 75% of our flower rooms. This means that the complexity of maintaining consistent room environments becomes a greater challenge due to the micro-climates in rooms. The Airoclean420 max allowed us to purify our air in the larger grow rooms. After 1.5 years, we have had no issues with the units – and 100+ units installed.

David Lawson, Chief Operating Officer, TruFusion

At Perpetual Gardens we have Airclean420 units installed in all of our flowering and drying rooms. We have found this is the most useful tool available to prevent Powdery Mildew and decrease overall microbial loads in the dry space. We have not failed a microbial test since we installed the units. Thank you Airoclean420!

Andrew Patterson, Owner Perpetual Gardens
