Easy to use smoke eater calculator

     Below you will find the necessary smoke eater calculator to determine which machines will best suit your needs and how many you will need.  Each set of circumstances will dictate the layout and number of smoke eaters necessary per room or area.  For instance, you may require fewer office smoke eaters than restaurant smoke eaters.  That is why there are different sizes and types of machines.  This information is for reference only, in determining how many smoke removal air purifiers are necessary for your conditions.  We are happy to talk to you by phone so you get the perfect fit for your specific situation.

How do I know which machine  and how many I will need?

     The simple smoke eater calculator below will help you determine which machine you may want and how many are needed for each room.  Unit of measurement is BLACK for feet and BLUE for metric.  Start by finding out the amount of cubic feet per minute (CFM) required.  Metric conversions of cubic meters per hour (CMH) are shown in BLUE  in the Air Cleaner CFM Capacity table below to help our international customers determine how many machines you may need.

CFM required = Length of room x Width x Height x ACH (air changes per hour) / 60 min

Enter - L - Length of your room measured in feet L =
Enter - W - Width of your room measured in feet W =
Enter - H - Height of your room measured in feetH =
Enter - ACH - Air Changes per Hour - from table ACH =
Amount of CFM required - CFM =

 Air Changes per Hour (ACH)

  6    Light           General Offices, Computer Rooms
  8   Average     Conference Rooms, Break Rooms, Designated Smoking Areas
12   Heavy         Bingo Halls, Extra Smokey Areas

CMH required = Length of room x Width x Height x ACH (air changes per hour) / 60 min

Enter - L - Length of your room measured in meters L =
Enter - W - Width of your room measured in meters W =
Enter - H - Height of your room measured in metersH =
Enter - ACH - Air Changes per Hour - from table ACH =
Amount of CMH required - CMH =

Quantity of Air Cleaners = Amount of CFM (CMH) required / Air Cleaner CFM (CMH) Capacity

It is our recommendation that you use the values for Medium capacity for two reasons.

  1. The machines are more efficient at slower speeds and less noisy.
  2. If you need to run them at high speed to keep up with normal conditions, you will not be able to keep up during special events where you would have larger crowds.  Many of our customers report increased customer count just by adding smoke air cleaners to their businesses.
