Determining the Quantity of Air
Cleaners for Your Application
-
The
size of the area to be cleaned - length x width x ceiling height
-
Is this
for the purpose of removing dust mites and other allergens, or are there
smokers in this area? Is there a high level of pollutants in the area?
-
What is
the main goal of treating the air in this area? Removal of a specific
pollutant such as smoke or pollen, overall cleaning and freshening of the
environment or perhaps saving energy by re-circulating cleaned air rather
than exhausting dirty air are among many reasons.
-
What is
the current airflow of the space to be treated? Existing heating and air
conditioning duct placement, unitary heaters, exhaust fans and where they
are placed are of importance when setting up your air cleaner(s).
Use the following table to estimate the
number of
air changes required for your application:
| Pollutant
Concentration |
Suggested
Number of Air Change/Hour |
Typical Application
for Suggested Number of Air Changes per Hour |
|
Low |
4-8 |
Household-(allergies/dust),
Office areas, Etc. |
| Medium |
9-12 |
Beauty Salons, Photo
Labs, Etc. |
|
High |
13-16 |
Restaurants, Night
Clubs, Bingo Halls, Bowling Alleys, Casinos, Cigar Bars, Etc. |
Each
commercial air cleaner provides an level of air cleaning capacity which is measured
in cubic feet per minute (CFM). Every model listed on these pages has a
cfm rating which will help you in determine which model you would need to
effectively clean the area which is polluted.
STEP 1
- Calculate the volume of the area to be cleaned in cubic feet.
Length x Width x
Height of area = Cubic Volume
STEP 2
- Divide the volume by 60 which represents minutes/hour.
Volume of Area ÷
60 minutes in an hour = Cubic Feet Per Minute Required for
ONE AIR CHANGE/HOUR
STEP 3
- Multiply the number of cfm's required in step #2 by the number of air
changes desired from the chart above.
Cubic Feet per
Minute (#2) x #of Air Changes/hour (from chart above) =
Cubic Feet per Minute (CFM) required for this application
STEP 4
- Compare the Cubic Feet per Minute (CFM) required with the cfm rating of
the units you are considering. If the cfm required is more than any of the
cfm ratings on an individual unit, you will need more than one unit for that
application.
CFM required for One Air
Change/Hour x Air Changes/Hour Needed =
CFM's Needed for Your Application
EXAMPLE SPACE CALCULATION
Room dimensions: 50' x 100'
x 10' ceiling
Type of area: Restaurant or
Lounge
Air Changes Desired: 16 Air
Changes/Hour (heavy pollution level)
Step 1 - Volume
50' x 100' x 10' = 50,000
cubic feet
Step 2 - Find Out CFM Required
for One Air Change/Hour
50,000 Cu. Ft.÷
60 Minutes in an Hour = 833 cubic feet/Minute = ONE Air Change in an
Hour
Step 3 - Total Volume Per Minute
To Be Cleaned
833cfm x 16 air changes =
13,328 cfm
Step 4 - Number of Units Needed
13,328 cfm ÷ cfm of chosen
unit = Number of Units Needed
