How to: Simplest Air Filter Ever
This is a really simple trick I have come with to create a simple air filter for about $30. It does a great job of cleaning the air and moves a much greater volume of air than the $100-$200 fancy units you can buy in stores.
So here is how to do it, open everything up, place the filter on the intake side of the fan, and wrap the bungee cord across the filter and hook it into the outlet edge of the fan on the other side at the top and bottom of the fan to hold it in place. Place this new unit into whatever area you want to clean the air in and turn the fan on.
Voila, clean air, you’re welcome for the extra $100 you just saved.
