Materials You’ll Need

• Box fan
• 20×20-inch furnace filter
• Cardboard
• Duct tape
• Scissors
• Ruler or measuring tape

Step-by-Step Instructions

1. Prepare the Box Fan

Remove the front grille of the box fan. This will allow you to access the inside of the fan.

2. Cut the Cardboard

Measure the inside of the box fan and cut two pieces of cardboard to fit. These cardboard pieces will act as the frame for the air filter.

3. Attach the Cardboard to the Fan

Place one piece of cardboard on the inside of the fan, behind the front grille. Use duct tape to secure it in place. Repeat this step with the second piece of cardboard, placing it on the opposite side of the fan.

4. Cut the Furnace Filter

Measure the opening of the cardboard frame and cut the furnace filter to fit. The filter should fit snugly inside the frame.

5. Insert the Furnace Filter

Place the furnace filter inside the cardboard frame. Make sure that the filter is facing the correct direction (typically with the arrows pointing towards the fan).

6. Secure the Filter

Use duct tape to secure the furnace filter to the cardboard frame. Wrap the duct tape around the edges of the filter to ensure a tight seal.

7. Reattach the Front Grille

Reattach the front grille to the box fan. The DIY air filter box fan is now complete.
