What size carbon filter for 4×4 grow tent?

The size of the carbon filter for 4×4 grow tents depends on the volume of the grow tent and the CFM.

For example, if one uses lights worth more pressure and watts, the heat flow will be high accordingly. Considering the high amount of pressure and watts, one has to install a filter that is 20% more CFM value than the overall calculation.

Carbon filters last almost 18-24 months or a minimum of two years. In most cases, carbon filters seem to work fine if the pressure is less, providing service up to 4 years.

There is a specific timeline for most carbon filters because they get saturated over time. The saturation of a carbon filter blocks it to cleanse the air of the grow room. Furthermore, plant types, usage, humidity, and carbon quality are responsible factors for the lifeline of carbon filters too.

Where to put a carbon filter in 4×4 grow tent?

Installation of the carbon filter is rather easy. After you’re done assembling the filters on the floor, set the best exhaust fan for 4×4 grow tent on the top of the carbon filter. The tapered side of the filter has to be pointed down.

Wraps of duct tape in 1-2 amounts are enough to connect the fan with the filter. A duct clamp allows firm attachment of the fan.

Will a carbon filter eliminate all smells?

The feasibility of activated carbon is much higher than any other mechanical purifier. Hence, a carbon filter does a great job of removing foul odor.

Being an absorbent, carbon filters are a powerful source of purifier that traps the odor inside the filter and ultimately retains it.

However, carbon filters get saturated over time, so they’ve to be frequently cleaned. Most carbon filters have a capacity of trapping 99.97% of particles. The excellent retention efficiency makes people choose carbon filters over any other purifiers.
