When you are growing indoors, managing the odor of your grow is something you must do. You may like how your grow smells, but your neighbors might not. In either case, if you don’t take any measures to reduce the odor, it may become a problem for you and others. This is where an exhaust filter comes in.

What is an exhaust filter?

An exhaust filter is an essential part of your ventilation system. The other parts include intake fans and filters. The ventilation system in any grow room should exchange the air every 1-3 minutes. The intake system lets clean, fresh air in while the exhaust system gets rid of the stinky, hot air. This is important because stagnant air can become excessively humid and conducive for pests.

You can place the exhaust filter behind or in front of your exhaust fan. In both cases, the dirty air heavy with strong odor is forced to pass through the filter before it leaves the grow space.

Why use a carbon filter in a grow room?

The main purpose of a carbon filter is to eliminate the unpleasant odor from a grow space. When the exhaust fan pulls out the stinky, hot air, the activated carbon in the filter traps the molecules that are causing the smell. This activated carbon functions like a sponge, trapping anything that is not air. In this way, the air gets purified of emissions and odor as it leaves your grow room.

Odor elimination is important for indoor grows in grow tents and grow rooms, so if you are an indoor grower, you should consider using a carbon filter. Carbon filters also allow you to have discretion and privacy because they hide the smell of your grow, preventing your neighbors to detect it.

When should you replace carbon filters?

Since carbon filters keep trapping the odor molecules, a point will come when they cannot absorb any more of them. This is when they become saturated, and there is no set life span as to when they will reach this stage. When this happens, the filters lose their effectiveness and need to be replaced.

One way to identify if it is time to replace them or not is to see when you begin to detect the smell of your grow again. The carbon pre-filter also needs to be replaced regularly.

What are the types of exhaust filters?

There are several types of exhaust filters available at Groindoor.com. The one you should choose depends on your growing space’s size and where you would like to position it.

Some types include:

The carbon exhaust filter is the most common and versatile option because it is highly efficient at odor removal.
