Materials You’ll Need
- Box fan
- Furnace filter (MERV rating of 11 or higher)
- Cardboard
- Duct tape
- Scissors or utility knife

Step-by-Step Instructions
1. Prepare the Box Fan: Remove the front grill of the box fan.
2. Cut the Cardboard: Measure and cut a piece of cardboard to fit the size of the fan’s opening.
3. Attach the Filter: Place the furnace filter on top of the cardboard.
4. Secure the Filter: Tape the filter securely to the cardboard using duct tape.
