The Ultimate Guide to Air Sterilization in Cannabis Cultivation

In the world of cannabis cultivation, the purity of the air and the cleanliness of surfaces in your grow room can significantly impact the health and yield of your plants. While traditional air sterilization methods have provided various levels of protection, none compares to the innovative efficiency and safety offered by the AirROS surface & air sterilizer solution. This guide will explore why air sterilization is crucial in cannabis cultivation and how the AirROS system stands above traditional methods as the best alternative for growers.

Why Sterilize Your Grow Room Air and Surfaces?

Creating a sterile environment in your cannabis grow room is essential for several key reasons:

  • Prevents mold, mildew, and other pathogens, which can drastically affect plant health and yield.
  • Reduces the spread of airborne diseases, safeguarding your crop from being compromised.
  • Ensures overall hygiene of the grow environment, benefiting both the plants and the cultivators.

Traditional Air Sterilization Methods

While the AirROS surface & air sterilization in cannabis solution represents the cutting edge in grow room sterilization technology, understanding traditional methods is crucial for appreciating the advancements AirROS offers. Below, we delve deeper into each method, outlining their mechanisms, benefits, and limitations.

1. HEPA Filters

What They Are

High-Efficiency Particulate Air (HEPA) filters are a standard in air purification, capable of trapping 99.97% of particles that are 0.3 microns in diameter. Their dense fiber mesh filters particles like pollen, dust, mold spores, and bacteria from the air.


  • High efficiency in collection particulate matter.
  • Widely available and easy to integrate into existing ventilation systems.


  • Does not neutralize or kill pathogens; merely traps them.
  • Requires regular replacement to maintain effectiveness.

2. UV-C Light Sterilization

What It Is

UV-C light, a category of ultraviolet light, has germicidal properties capable of inactivating microorganisms by damaging their DNA. It’s used in various settings, including hospitals, to sterilize air, water, and surfaces.


  • Effective at killing bacteria, viruses, and fungi.
  • Chemical-free and environmentally friendly.


  • Only sterillizes the air in short distance from the UV light. Requires multiple of UV bubls and electrical cost can incrase dramatically.
  • Less effective if pathogens are not directly exposed to the UV-C light for an adequate duration.

3. Ozone Generators

What They Are

Ozone generators produce ozone (O3), a molecule that oxidizes and thus destroys many types of pathogens and odors. While effective for sterilization, ozone is a powerful oxidant that must be used with caution.


  • Broad-spectrum effectiveness against pathogens and odors.
  • Does not leave chemical residues.


  • High concentrations can be harmful to plants, humans, and pets.
  • Can only be used as a shock treatment.

4. Activated Carbon Filters

What They Are

Activated carbon filters use a bed of activated carbon to remove contaminants and odors from the air through adsorption. While they do not directly sterilize the air, they significantly improve air quality.


  • Highly effective at odor removal, which is beneficial for controlling the strong odors associated with cannabis cultivation.
  • Can adsorb some volatile organic compounds (VOCs) and other pollutants.


  • Does not kill or inactivate microorganisms.
  • Carbon filters become saturated over time and need to be replaced.

5. Electrostatic Air Purifiers

What They Are

Electrostatic air purifiers use an electrical charge to attract and capture airborne particles. These devices can remove dust, pollen, and some microorganisms from the air.


  • Can remove smaller particles than HEPA filters.
  • Often washable and reusable, offering a cost-effective solution.


  • Varied effectiveness against microorganisms; does not neutralize them but merely traps them.
  • Requires regular cleaning to maintain efficiency.

6. Photocatalytic Oxidation (PCO) Technology

What It Is

Photocatalytic Oxidation (PCO) is an advanced air purification technology develped by NASA that utilizes UV light in combination with a photocatalyst, typically titanium dioxide (TiO2), to oxidize pollutants in the air. When airborne contaminants like bacteria, viruses, VOCs (Volatile Organic Compounds), and molds come into contact with the catalyst, they are broken down into harmless substances such as water and carbon dioxide.


  • Effective at reducing a wide range of airborne contaminants, including those that are too small for filters to capture.
  • Produces no harmful byproducts, making it safe for use around humans and plants.
  • Helps in reducing odors and volatile organic compounds, improving air quality significantly.


  • The effectiveness of PCO technology depends on the amount of time pollutants are in contact with the catalyst, which can vary based on air flow and the design of the purifier.
  • Not all PCO units are created equal; efficiency can vary significantly depending on the specific design and quality of the unit.
  • While it can reduce a large number of contaminants, it may not be as effective against certain types of particles or microorganisms without sufficient contact time or UV intensity.
  • It relies the air going through the PCO system. As a result it can NOT prevent & reduce cross-contamination.
  • It does not sanitize surfaces including hard to reach areas due to only be effective in short range within few feet from the device.

Introducing AirROS: The Future of Air Sterilization in Cannabis Cultivation

AirROS utilizes advanced Reactive Oxygen Species (ROS) technology to offer a superior air sterilization solution. Here’s why AirROS is the game-changer for cannabis cultivators:

  • Advanced ROS Technology: Uses low levels of ozone and hydrogen peroxide gas phase to safely sterilize air and surfaces continuously.
