Inline fans move the air effectively and efficiently so that the heat in your grow space does not get above what is comfortable for weed plants, about 90 degrees. Increased heat can cause your plants to become dry and wilted, or to absorb more nutrient solution that they regularly would, causing nutrient burn. More heat also means increased relative humidity in most climates, which can create the perfect environment for mold and pests to infest your plants.
Another benefit of good ventilation is the ability to remove odors from your grow op. Most home growers do not like to advertise the fact that they grow cannabis. This is a personal choice and may not always have to do with the legality of marijuana in your state.
Cannabis plants have a very strong and very recognizable smell, and although home growers certainly love the finished product, you might not want to smell it all day every day and your neighbors most likely do not want to either.
Charcoal or carbon filters offer the most effective means of eliminating this odor. The outbound air from your grow room is passed through a thick pad filled with carbon or activated charcoal, which uses chemical absorption to remove odors from the ventilated air. The molecules carrying the cannabis odor are trapped inside of the pores of the carbon molecules. This is one of the most effective odor filtration methods available and has served weed farmers well for years.

Many filters are made of galvanized steel making them durable and better performance. Carbon filter made using premium material are pricier compared to other materials. Also, the maintenance of carbon filter made of premium material is easier.
- Pre-filters: Many quality carbon filters come with pre-filters. They play a major role in assisting in the elimination of dust particles in grow room. In addition, they make inline fan and carbon filter work more efficiently while increasing the carbon filter life span.

Compact carbon filters likewise have better smell and odor absorbent capabilities. On top of that, you can transport it easily from one position to another in the grow room.
- Thickness: Filters that have thicker carbon has better absorption abilities. Furthermore, Filters that has more carbon thickness will absorb more odor compared to those with less thick carbon. Nevertheless, they are worth every cent
