Determining the Model and Quantity of Air Cleaners for Your Application
-
-
- 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?The size of the area to be cleaned - length x width x ceiling height
- 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).
For a faxed or mailed quotation, please send us the measurements of the area you wish to clean and the number of air changes/hour (see chart below) you wish to accomplish. We'll do the work for you...just send us an e-mail!

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 LakeAir brand air cleaner provides a 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 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
If you have any difficulty determining the required unit(s), please call LakeAir at 1-800-558-9436 and request a faxed quotation or send us an e-mail with the size of the area and the number of air changes/hour you wish to achieve.
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
(Model LA-2000): 13,328 cfm ÷ 2,100 cfm = 6.34 or 6-7 units
(Model LA-1400): 13,333 cfm ÷ 1,100 cfm = 12.09 or 12-13 units
