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.

TerraBloom Air Carbon Filter

The TerraBloom filter uses top-grade RC-48 charcoal from Australia packed into a 1.8-inch filter bed, resulting in more carbon and more effective airflow to prevent smell in your room. As there is more carbon in the filter bed, it also means that the unit has a longer lifespan that filters that have a thinner filter bed. In fact, the life span of this filter is what helped it to earn a spot on our list. TerraBloom promises two years of continuous usage from this unit.

The Phresh Carbon Filter is a very effective filter that will provide an environment that would be ideal for any grow room. If the reviews we’ve seen other users leave about this filter are anything to go by, you’ll certainly love the performance of this filter. The carbon filter setup in grow tent is also made easy by the shape of the filter.

ECO FARM Carbon Filter

Similar to other models, the ECO FARM 4″ Carbon filter also comes with a pre-filter unit. This pre-filter unit will make sure that the air passing through the filter gets thoroughly cleaned.

The carbon charcoal used in this filter is commonly used in most filters. A unique attribute of this device is that the company ECO FARM claims that its device will filter 100% of air flow at over 200 cfm.

Having a reversible flange means that there are two ways you can use this carbon filter. We also like this 4 inch carbon filter because it provides great value for the cost and a long two-year lifespan.

Final Notes On Carbon Filters
Although not necessary to grow big buds indoors, a carbon filter inside a grow tent is always a good thing to have. Not just for the smell but also for your plant’s health. Air circulation inside a tent is a must for healthy buds hands down.

A carbon filter for grow room is a perfect add on to venting systems because they do what they are supposed to do.
