How to Use an Air Scrubber Calculator

When it comes to removing mold spores, bacteria, chemical fumes, or other pollutants from a contaminated space, getting the airflow right is crucial. Too much or too little filtration can lead to poor results. That’s why using an air scrubber calculator to help you find the right size is so important.

An air scrubber calculator is a negative air machine that exhausts the contaminated environment into a clean space, then recycles the clean air back into the contaminant area. Whether you’re using a portable air scrubber or installing a permanent system, the same principles apply. You’ll need to know the volume of the contaminant space and the number of air changes per hour required. From there, you’ll need to determine the air scrubber CFM and ACH.

The first step is to calculate the cubic volume of the contaminated space. This can be done by multiplying the room’s square footage and ceiling height. Once you have this information, it’s time to determine the ideal ACH. ASHRAE (The American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends 4 ACH for patient rooms in hospitals and 6 ACH for general use spaces.

Once you’ve determined the air scrubber CFM and ACH, it’s time to calculate how many units are needed for the project. To do this, you’ll need to know the air scrubber’s CFM rating, which can usually be found in the product specifications. Next, you’ll need to divide the CFM rating by the ACH to get the treatment volume in cubic feet needed.
