My kitchen was being remodeled and the air was dusty while being remodeled so I made this. It may sound stupid but the reason I used a box is so I get more airflow versus just sticking tissues to the front of the fan.
Things you'll need:
A fan (it will be better if it was a tower fan or a centrifugal fan)
Some tape (okay maybe a lot)
And a cutting tool of any kind
Step 1: Step 1: Cut a Hole for the Fan
Cut a hole for the fan slightly smaller than the fan itself.
