Steps to Make Your Air Purifier

Now, take your measuring tape. Measure the size of the fan. You need the filter to be the same size as the fan.
Step 3: Cut The Filter
Use your scissors to cut the filter. Make sure it matches the fan size. Be careful. Scissors can be sharp.
Step 4: Attach The Filter To The Fan
Use duct tape to attach the filter to the fan. The filter should cover the back of the fan. Tape all sides so no air escapes.
Step 5: Test Your Air Purifier
Plug in your fan. Turn it on. Feel the air. It should be cleaner now. You did it! You made an air purifier.
