Air Purification Resources

Essential Air Quality Control for Professional Growers

In controlled environment agriculture (CEA), managing air quality is as critical as lighting and nutrition. Stagnant air and uncontrolled odors can lead to pest issues, mold growth, and complaints from neighboring properties. Hydrofarm provides the equipment needed to scrub air of contaminants and effectively neutralize strong organic odors.

What is the Difference Between a Carbon Filter and an Inline Filter?

A standard carbon filter is typically placed at the beginning of an exhaust system to scrub air as it leaves the grow space. An inline filter is designed to be installed within the ducting run, allowing for a more flexible configuration in complex ventilation systems. Both utilize activated carbon to remove odors and volatile organic compounds (VOCs), while pre-filters capture particulates.

How Often Should Pre-filters Be Replaced?

Pre-filters are the first line of defense, trapping dust and large particulates before they reach the carbon bed. To maintain airflow efficiency and extend the life of the main carbon filter, pre-filters should generally be inspected monthly and replaced or washed when they become visibly dirty or discolored.

Can Ona Products Be Used Directly Inside the Grow Room?

Ona products are powerful odor neutralizers. While they are safe to use around plants, it is generally recommended to use them in exhaust ducts or areas outside the direct grow space (such as hallways or reception areas) to avoid altering the plants' natural scent profile.

How Do I Size a Carbon Filter for My Ventilation System?

To ensure effective purification, the CFM (Cubic Feet per Minute) rating of your carbon filter should match or slightly exceed that of your exhaust fan. This ensures that the air passes through the carbon bed at the correct speed for optimal adsorption.
