Phat Filter Carbon Filter

The 2-inch bed provides a deeper layer of carbon for air to pass through, which increases the contact time between the air and the filtration media. This results in more efficient odor adsorption and a longer lifespan compared to filters with thinner carbon beds.

This filter is rated for an airflow of 950 CFM. To ensure optimal performance and prevent backpressure, you should pair it with an inline fan that matches or is slightly lower than this CFM rating.

The filter measures 8 inches in diameter and 39 inches in length. Before purchasing, verify that your ventilation setup has enough clearance to accommodate these dimensions and that your fan's ducting matches the 8-inch intake.

These are industry metrics used to measure the quality and porosity of the carbon. A higher Butane Number indicates that the carbon is more effective at trapping volatile organic compounds, meaning the filter will handle stronger odors more effectively.

While the lifespan depends on the humidity levels and the concentration of pollutants in your environment, the 2-inch carbon bed is designed for extended use. In most residential or standard grow room setups, you can typically expect it to last between 12 to 18 months before the carbon becomes saturated.
