How many components to buy for your window:

Follow this instruction to order the complete set of Air-thru-window Filter to fit in your window.

Requirement:  Window track Width must be 1.25″ or more.

Step 1

Measure from Top of the window track (left image), to Lower Edge of the window opening (lower left image).

Write the measurement in “Feet” (Ft) and “Inches” (In). 

 

Example:

38 In = 3 Ft + 2 In

Step 2

The number of “Ft” in the measurement is the quantity of Cases and Cartridges you need.  The number of “In” in the measurement is the quantity of Spacers you need.

 

Example:

The image on the left shows measurement of 3 Ft + 2 In, so you need to buy 3 Cases, 3 Cartridges, and 2 Spacers.

 

Note:

If the number of “In” is 6 or more, then you need 1 more extra Spacer.

Example:  For measurement of 5 Ft + 6 In, you need 5 Cases, 5 Cartridges, and 7 Spacers.
