arbon filters are used in conjunction with air purifiers to filter out particles, dust and odors from the air. Carbon has a high surface area which allows it to attract airborne particles.
This is why they are used in conjunction with air purifiers. The most common carbon filters that I have come across in my research are the carbon block filters. There are a couple of problems with using a carbon filter in a grow tent. The first is that the carbon needs to be maintained to keep its effectiveness. This means you need to clean it regularly. It’s not as hard as it sounds.
There are a few ways you can do this. You can use a vacuum cleaner and run it over the carbon or if you want to be more hands on you can wash it in water and soap. Either way, you need to get rid of the sooty build up that is inevitable when using a carbon filter. The second problem with using a carbon filter is that there is a limit to how much air can pass through them. You only need to look at the dimensions of the carbon to see how big of an issue this could be. If you have a 10 ft x 10 ft grow tent, then you need to use a carbon filter that is about 4 inches thick. This will allow for the air to flow through the carbon. If you are growing in a larger tent, then you will need a bigger carbon filter. A final issue with using a carbon filter is that it does not absorb odors. If you are growing in a tent and you are using an air purifier, then you won’t need to worry about this as the purifier will take care of it.
