The Most Effective and Economical way to Prevent Powdery Mildew


For the prevention of Powdery Mildew, Botrytis, Penicillium and other fungus that pose a threat the indoor Cannabis growers. Uvairos proprietary custom real time sizing and performance utilizes CFM, duct dimensions, and cubic feet per space being treated. Performance objective is to disinfect the air of Powdery Mildew and Botrytis within the space at a rate of 95% or higher every hour the unit is operating. This disinfection rate is based on 8-12 air changes per hour.

Eliminates up to 99.9% of airborne powdery mildew every hour • Reduces fungicide use by up to 90% • Reduces labor costs related to the use of fungicides • Helps enrich terpenes and enhances aromas • Provides an environment for consistency, harvest after harvest • Improves microbiological state testing compliance



The power of the sun inside your hvac system

The GrowSaver™ system uses the power of the sun’s UV rays to disinfect the air and prevent crop contamination. A patented high-intensity UVC chamber, directly integrated with the cultivation facilities HVAC system, continuously kills up to 99.9% of airborne Powdery Mildew, Mould and Bacteria every hour.

The best technology on the market

Only Uvairos uses high-intensity T6 germicidal UVC lamps mounted parallel to airflow on anodized aluminum parabolic reflectors for a full 360-degree disinfection of passing airborne contaminants.

A chemical-free solution

The GrowSaver™ system virtually eliminates the need for fungicides. It is a non-invasive, non-toxic, completely green solution that leaves zero residue and no environmental footprint.

Proven effectiveness

Tested by the U.S. EPA and Homeland Security for Biological Inactivation Efficiency by HVAC In-Duct Ultraviolet Light Air Cleaners to achieve up to 99.9% disinfection on one pass inactivation.


Powdery Mildew is one of the most common and widespread distributed diseases of plants for indoor and outdoor production. This disease is responsible for significant economic losses in many floricultural and vegetable crops. More recently, powdery mildew has been found to be a serious threat to Cannabis production. Although infections usually do not result in plant death, they reduce the crop consistency, yield, aesthetics, and value. In many cases, infected plants will have to be destroyed. For an indoor Cannabis grower, powdery mildew tends to be more problematic in the spring and fall when day-night temperatures favor high relative humidity, but it can develop at any time during any production cycle. An understanding of the disease cycle, organisms involved, and factors that favor disease development will contribute to successful management of this disease. Experience has proven that adequate air filtration combined with high intensity UV-C germicidal air disinfection within the grow facility is a powerful new way to prevent Powdery Mildew outbreaks.
