I already had a box fan in Little Sister’s bedroom (that we run mainly for white noise). So we thought we would give it a test run as a new air purifier. We had already purchased an air purifier last year for our son’s room that we have been happy with, but the filters alone are ridiculously expensive. I am THRILLED that we can now make our very own! 🙂
Here’s what you’ll need:
*Both the box fan and the air filters can be purchased at most grocery stores or hardware stores for much cheaper than the links above, I simply included them for your convenience. I bought my box fan for $5 on clearance at our local grocery store last year and my husband found the filter for about $7 at Lowes.
1. Unwrap your filter. This filter didn’t have a MERV rating on the package, but I would recommend finding one with a MERV rating of 13 or higher if you are using it for someone with allergies.
2. Secure filter to the back of your fan with rubberbands. You could also use duct tape if you would rather. The electrical plug was in the back of my box fan, so I just snipped a small hole in the filter so that I could plug in the cord.
3. Turn on the fan and enjoy cleaner air!
