Eliminate Odors And Fresh The Air: The filter’s internal core is made of 1050+ activated charcoal imported from Australia to bring 100%-fresh air and eliminate unwanted odors, pungent smells, and particulates out of growing tents and rooms. The double-sided galvanized steel mesh provides 53% of the open area for airflow to pass through so that the odor absorption and elimination process can be carried out thoroughly. (The carbon filter was covered by a prefilter cloth; do not remove it when using.)

Durable Flexible Ducting & Connecting Accessories: This ventilation kit is paired with a 33-ft-long PVC thermoplastic flexible duct tube to direct the air in and out properly, durable and easy to use.

Knowledge Base

Can you attach a carbon filter directly to a fan?

One other option is to directly connect your carbon filter to your inline fan if you’re not using a grow light hood. The idea is any amount of air leaving your grow build must pass through your carbon filter so that odor does not spread.

Do inline fans push or pull air better?

Inline fans are generally more effective at pushing air through ducting, as opposed to pulling air. Therefore, especially for long sections of ducting, position the fan at the inlet end, not the outlet

How safe are carbon filters?

Are Activated Carbon Filters Safe? Yes. Activated carbon filters and air purifiers that use a PM 2.5 activated carbon filter are safe for use in commercial and residential spaces. Moreover, activated carbon filters are effective at removing volatile organic compounds commonly found in most households.

Is it better to push or pull air through a carbon filter?

Bottom Line: Controlled tests found no benefit of putting the air filter on the back (pulling) compared to the front (pushing).

How much does a carbon filter reduce airflow?

It is wise to factor in a 10% -25% drop in airflow due to the resistance of pulling through the carbon filter. Just remember, if you are running an exhaust system, DO NOT choose a fan that will exceed the exhaust rating of your filter.
