1. Upgrade Your Air Filters.
You can easily integrate both air filtration and odor mitigation into your current HVAC system by replacing the standard air filters with activated carbon filters. These filters specifically target odors and more effectively filter out dust, debris and other impurities.
If you are serious about a medical-grade environment for your facility, one of the best options available is using polarized media filters with activated carbon insert pads. Polarized media filters utilize electromagnetic polarization to maximize the collection of dust and pollutants in the air, which increases the effectiveness of air filtration and odor control. The carbon pads provide an additional layer of odor removal, providing maximum efficiency and benefit.
Upgrading filters is relatively inexpensive, and the costs are heavily offset by the reduced labor and cost of replacing those filters less frequently. These technologies are utilized by hospitals, laboratories and other clean facilities around the world and are a great option for cannabis cultivation facilities.
2. Use Carbon Scrubbers.
Cultivators wanting to create the cleanest environment possible can consider using activated carbon scrubbers in certain areas. These types of filters use pelletized granule carbon to remove odor, dust and pollutants from the air, and can be used as a standing unit in a space or as an exhaust filter. Just like the carbon in the air filters mentioned previously, these pellets remove dust, odor and other pollutants through the air as it passes through the filter. These are particularly helpful in areas where dust is created from grow media or the manicuring of dry plant material, and they have replaceable pre-filters that work well for this application. Carbon scrubbers also work great in smaller cultivation rooms or any product storage areas where odors might be an issue.
3. Use Ozone Generators for Maximum Odor Control.
Ozone generators use ultraviolet bulbs or corona discharge (an electrical discharge) to produce ozone gas that works on a molecular level to eliminate virtually all odor, molds, mildews and bacteria. Ozone can be used safely and easily by utilizing generators that fit directly into your exhaust lines.
This is one of the most effective methods for removing odors in the exhaust system. Using ozone indoors or in any cultivation area (and not in exhaust systems) is not recommended, as it can be harmful to plants and humans at concentrated levels, and some generators will not work under extremely humid conditions.
