To determine what size you need to order you will need to do one or all of the following.
1. If you have central air conditioning, go out and read the Model Number on the out door unit. Call an HVAC company in your area and find out what size you have. Then using our chart, below check the "Tons of Air Conditioning" area follow that line to the left and order that Model Number air cleaner.

2. If you can't determine your air conditioning size, or if you don't have central air conditioning, read the Model Number of your furnace, call an HVAC company in your area and find out how many tons of air conditioning your furnace is capable of. Again go to our chart and follow the same guidelines as in step # 1.

3. If neither of these first (2) options can be used, then shut the main power off to your furnace and open the blower door of your furnace. Measure the existing return air opening that is already cut out on your furnace. Using this information, compare it to the closest return cut out opening in our chart. Follow that line to the left and order that air cleaner.

* CFM = Cubic Feet of Air Per Minute. If you have central air conditioning this figure represents how much air can flow through the air cleaner. Each ton of air conditioning needs 400 C.F.M.

** Internal Pressure switch = Honeywell has a built in switch to NOT let the air cleaner work unless the furnace blower is running. This feature keeps from making Ozone which has an odor and can make a person irritable. You can also run the furnace blower continuously by selecting the "ON" position on your thermostat if you have central air conditioning, therefore cleaning your air all the time.
