Box Fan Air Filter Woodworking. I thought i would post a couple pictures of my inexpensive box fan air filter. I have been running this fan continuously for about two months now and i am shocked at how much dust it has actually collected. If you are only concerned about large particles generated from.
Like a lot of woodworkers, i made a cheap air cleaner for dust in my shop by attaching a furnace filter to a box fan.
In this video i build a box fan air filter for the shop. If your air quality is bad and you don't have an air purifier, an hvac filter taped to a box fan is better than nothing. You won't find a cheaper air filter on the market that moves as much air as this one, and the only maintenance it requires is changing the filters. The filter will restrict air flow which will put a higher strain on the motor causing it to use more electricity the nice thing about this box fan filter setup is you can use any filters you want. I just set the fan on my workbench whenever i am sanding. I thought i would post a couple pictures of my inexpensive box fan air filter. Altogether it'll cost you less than $50 in materials. It's a low resistance, high velocity air filter, so there is no drag on the fan.
