Odor and Pathogen Control is a must in any grow room. Nutrient solutions don't always smell as good as they work and harmful pathogens, such as mold, can take hold in a higher humidity environment such as that of an operating grow room. By "scrubbing" your outgoing air these options help keep the air smelling fresh and healthy.  Breathe clean! Breathe healthy. There are several reliable ways to do this: Air Fresheners These come in many shapes and sizes. They are effective in masking odors, but not eliminating them. They also have no effect on pathogen control. There are aerosols that claim and are effective odor neutralizers. Check your labels.

Carbon Filters
Carbon filters are used for many applications involving filtration, including water filters and odor and pathogen control. The use of special manufacturing techniques results in highly porous charcoals that have surface areas of 300-2,000 square meters per gram. These so-called active, or activated, charcoals are widely used to adsorb odorous or colored substances from gases or liquids. The word adsorb is important here. When a material adsorbs something, it attaches to it by chemical attraction. The huge surface area of activated charcoal gives it countless bonding sites. When certain chemicals pass next to the carbon surface, they attach to the surface and are trapped. The surface area of activated carbon is significant, but finite. Your carbon should be replaced every 12-18 months for optimal performance.

Ozone Generators
Most ozone generators take oxygen from the air, transform some of that oxygen into ozone, and then release the ozone back into the air. Interestingly ozone occurs quite readily in nature, most often as a result of lightning strikes that occur during thunderstorms. That fresh, clean, spring rain smell that we notice after a storm results from nature's creation of ozone. Waterfalls also create ozone. However, we are probably most familiar with ozone from reading about the "ozone layer" that circles the planet above the Earth's atmosphere. Here, the ozone is created by the sun's ultraviolet rays and then serves to protect us from the ultraviolet radiation. Because an ozone molecule is made up of three oxygen atoms, ozone is naturally unstable; each ozone molecule works to release its extra atom to become oxygen again. The atoms released combine with organic compounds in the air changing their chemical makeup and, thus, neutralizing their odorous and pathogenic properties. When it comes to ozone generators, it's important to note that the popular notion "more is better" doesn't apply. The FDA has set a limit of 0.05 parts per million of ozone in indoor air, and, because too much ozone can be harmful to your plants and you, ozone generators should be used with caution. However, with proper use ozone is an extremely effective means of controlling pathogens and odors in the growroom. Ozone generators can also be utilized for situations outside of the growing environment, such as vacation homes, pet situations, indoor smoking situations, and many others.
