Best Carbon Filter for Weed 2020
Why use carbon filters?
Is the use of carbon filters the only way to reduce the spread of the pungent smell that comes from a grow room? The answer is no however, carbon filters are the most effective and highly preferred way to absorb smells that go beyond the grow room. The use of gel and air purifiers only masks the smell.
What to Look For In a Carbon Filter?
Grow Room Size
What size carbon filter do you need for your grow room? This is the very first question that you have to ask yourself.
Start by calculating the volume of air used in your grow room. For example, if your grow room is 10 by 12 feet, and your ceiling is 8.5 feet high. The volume is 1020 cubic feet.
Similarly, if you are growing in a tent, it is the air volume of the grow tent itself that you need to take into as far as your calculations go.
How to Know the Time to Change a Carbon Filter?
When the activated carbon inside the filter saturates, it stops absorbing odor. Hence, an indication of the time to change the carbon filter is that it stops trapping smell from the environment.
Your grow room will have the bad smell back when the carbon filter gets out of order. However, being in the same environment might make your nose receptors accustomed to the smell. It is always a good idea to make someone else smell the marijuana grow tent.
You can also smell the carbon inside the filter and look for a strong carbon smell to see how alive the activated charcoal is. This can be done every 3 to 4 months to ensure proper functioning.
