carbon filter inside or outside tent Covert Carbon Filter 4 inch x 12 inch, 200 CFM

Activated carbon filters are the best way to eliminate most VOCs (Volatile Organic Compounds), gasses, and odors from the air. Combined with a fan in a ventilation system, 99.9% of noxious odors can be trapped inside the filter for good.

Through adsorption, activated carbon literally traps the carbon-based contaminants in the air that could harm you and keep them locked tight inside the filter. Using activated carbon ensures optimal pore structure and that the pathways the air travels through the filter are optimal, so that the maximum amount of contaminant becomes trapped in the filter and does not escape into the air.

• Machine packed activated virgin carbon allows for maximum air scrubbing
• Highly effective, low density virgin carbon
• 50mm carbon bed ensures all air is cleaned
• Inner and outer mesh provides 53% open area allowing increased air flow
• Built-in flange
• Includes pre-filter for prolonged filter life
• Lightweight construction allows for easy hanging
• No maintenance required
• Long life span (12-18 months)

All Covert Filters come with a reusable pre-filter that will filter out the large particles before they enter the carbon bed which significantly extends the life of the virgin activated carbon.

Covert Filters have a built-on flange that is easy to attach to ducting or an inline fan. The lightweight and compact design makes for easy hanging and saves space.

Once you have your Covert Filter, you still need to ensure that it gets set up properly for maximum efficiency.

We've done our best to provide all the learning resources you may require in our Learning Center on how to properly install your Covert Carbon Filter.

This article - Grow Tent Setup Guide - goes over the entire process of setting up your grow tent. At Step 4 & Step 5 in this article we highlight different ventilation setup methods and what we prefer as well as every step required to properly install your filter.

Air-Cooled Lighting

Air-cooled HID light fixtures have duct flanges you can easily connect a fan and ducting to. You can see an example setup in the diagram to the right. This setup pulls air through the carbon filter, then through the light fixture and finally out of the tent.

A great upgrade for air-cooled lighting is to use a separate in-line fan just for the lighting ventilation. This will make both your light cooling and your carbon filter work more efficiently.

Closed Loop CO2 Ventilation

When using CO2 producing equipment inside of a tent, you want to avoid allowing that CO2 to exhaust from the tent. Therefore you want a “closed loop” system which will filter the air of odors by recirculating the air in the tent through a fan and filter. It is recommended to utilize LED or aircooled lighting to avoid heat buildup in the tent. Air conditioning is recommended for larger tents using CO2

Using CO2 for a grow tent is a more advanced technique. If you want to leanrn more about CO2 for growing we have a great article here
