Best Carbon Filter For Grow Room

Indoor grow rooms have many advantages, but it has some drawbacks as well. You don’t want your house to smell like a hotbox all the time. An odor-neutralizer or air purifier will not completely get rid of the smell. A carbon filter is the best option as it provides an air extraction solution that eliminates the odor and prevents it from being stuck somewhere in the house. When the carbon is treated with oxygen, it will have a porous surface. Air will pass through the carbon filter, but undesirable odors will bind to the carbon. The filters have to be replaced, but you’re assured that it will last for a long time.

How Carbon Filters Help

Carbon filters are large, durable tubes that contain a lot of carbon. It can be connected to the exhaust fan to force the extracted air from the grow room to pass through the carbon filter. A granular carbon filer is enough for a small room. A block filter is ideal for more massive operations. Check the fan’s cubic feet per minute or CFM to know what filter you should get. Make sure that the fan can handle the filter. Get a filter with a lower CFM value than the fan. A filter with the same CFM value as the fan is also a good option.

It is also essential that you set up everything correctly. Failure to do so increases the risk of possible air leak. Make sure that all the air that is being pulled from the room is going through the filter. The best way to do this is to integrate the filter in the exhaust system. You can place it after or before the exhaust fan. The air will either be pushed or pulled through the filter and neutralize all odors. The best way is to put the carbon filter as the air’s first passage. The fan must be the last component. You also need to make sure that everything is properly sealed.

How to Maximize the Carbon Filter

Air should only enter the exhaust system through the carbon filter, and it should go straight outside. The exhaust fan must be strong enough to produce a vacuum in the grow space. This way, the pungent odor is vented out of the room so quickly that the vacuum prevents any air from leaking into the room. If there is good suction, you will not smell anything outside the room.

Once there’s suction in the room, and you are directing foul air outside, you need to scrub odors out of that air before it escapes the house and this is where a carbon filter can help. If there are leaks around the grow light or in the ducting, the smelly odor can leave that way instead of going through the filter first. Air is scrubbed of smells as it is pulled in through the sides of the filter. That air has no smell when it’s vented outside.

Conclusion

When appropriately installed as part of your exhaust system, a carbon filter will prevent the odor of weed from leaking outside. It will not change the smell of your weed. When purchasing a carbon filter, you have to consider the size of the grow tent. Different sizes have different prices. The right carbon filter will keep the odor of the grow room is neutral and prevent the strong smell of weed from traveling outdoors quickly.
