HOW TO FIGURE OUT WHICH CAN FILTER & FAN YOU NEED:
The general idea is to change the air in your room / tent in a certain period of time (most people say every 3 or 5 minutes).
So, you calculate the size of your room in cubic feet: Length x Width x Height – eg. 4’ x 4’ x 7’ = 112 cubic feet
Then divide that by the amount of minutes you want the room cleared in – eg. 112 / 3
This gives you the minimum recommended fan CFM (cubic feet per minute) – eg. 37 cfm
Then match that established fan size to the appropriate sized CAN filter.
