These clips mount under your fan's own rear frame screws and gently pin the filter in place. Slide the filter in behind the arm and it stays put, even with just one clip on each side of the fan. The arm has a little built-in flex, so it holds the filter snug without crushing the frame.

WHAT YOU GET

6 clips in your choice of 11 colors (one color per pack). CLIPS ONLY, the fan and filter are NOT included. Two are enough for one fan (one on each side), so the pack covers three fans, or you can add more clips on one fan for extra hold. Your fan's existing screws are reused, nothing else to buy.

FITS

Lasko style 20 inch box fans with the round screw recess on the rear frame, and standard 20x20x1 filters (about 3/4 inch actual thickness).

CHECK BEFORE YOU ORDER

On the fan we tested, each rear frame screw sits in a round recess about 7 mm deep and 11.5 mm wide. If your fan looks different, message us before ordering.

INSTALL IN A MINUTE

Unplug the fan. Remove one rear frame screw, set the clip into the recess, and put the screw back through the clip. Repeat on the opposite side. Slide the filter in behind the arms. The screw is easy to reach with a Phillips screwdriver straight from the front.
