Step 1: Place the Extraction Kit onto your fan to determine the fit and the best location for the Velcro Strips so they align correctly (on each corner) before applying.

Step 2: Remove the protective film from the Velcro Strips and attach them to each corner of the box fan. The Velcro Strips should slightly wrap around each corner area to provide the best fit.

Step 3: Start at the bottom, place the filter onto the fan, ad adjust the filter to fit the fan feet as needed. Align the center of the filter to the fan and then the top. Secure the filter in place by removing the protective film from the other side of the Velcro and press tightly to attach.

*We recommend purchasing a black colored 20×20 box fan to conceal overspray better
