How to Calculate the Required CFM for Air Scrubbers

Posted by Mathilda Gustavsson on

Until recently, air scrubbers were mostly used by construction & restoration workers to clear the air of harmful airborne particles during demolition, drywalling and other renovation projects. 
But a lot has changed this pandemic year, and now people everywhere are buzzing about HEPA air scrubbers and their potential to help preventing the spread of the coronavirus.
The capacity of an air scrubber is measured in Cubic Feet per Minute (CFM). If you're considering an air scrubber or air filtration system for your business, you will have to consider the CFM needed for the size of your space.

Follow these steps to calculate how many CFM you will need

One cubic foot is the equivalent measure of 12” x 12” x 12”, which means that one CFM would dry an area of that size in one minute.


1. Calculate Your Room's Volume in Cubic Feet

To do this, multiply the square footage by the ceiling height. 
For example, if the floor has an area of 700 square feet (multiply the room's length by its width) and 8-foot ceilings. 
700 x 8 = 5,600 cubic feet of volume


2. Calculate the Total Cubic Feet per Hour

Multiply the room's volume (in cubic feet) by 6 to find the total cubic feet of filtration needed per hours. 
Example: 5,600 cubic feet x 6 = 33,600 cubic feet per hour


3. Convert to Cubic Feet per Minute

Divide the total cubic feet per hour by 60 to convert to cubic feet per minute (CFM)
Example: 33,600 cubic feet per hour / 60 minutes = 560 CFM.
