So I had an idea for a cheap air filter the other day that has worked out unbelievably great, really moves alot of (now fresher) air. Perhaps someone here could get some use out of it!

Ingredients:
A 20x20 Box Fan.
A 20x20 3M Furnace Filter (The activated charcoal filter one works great).
Some Duct Tape.

Altogether about $30 at Wal-Mart. Tape the filter on the back of the fan, (not the front) and voila! A cheap, DIY air filter that'll compete with high-end, several hundred dollar models.

We have one person in this house allergic to dust mites and wood smoke. It takes Filtrete Elite 2400 3m filters from Lowe's on the furnace, and a IQair HealthProPlus with annual purchase of all three filters (pre, charcoal, hepa) to deal with that and my issues with milo when it blooms and when they harvest.

That is a great and simple DIY if you are not at the near asthma end of air quality needed. Nice "Bodge".

I have one of these. I just tied the filter to the fan so it's easy to change, but blocked the spaces that the filter doesn't quite cover with tape.
