Dirt! Ewwwww!!!

Due to some allergy problems we have been having…..  and to deal with that New England Catarrh…. which appears to be one of the costs of living here in New England…..  I put an air filter in the basement.

It looks like this:

FilterYep. That’s right, it’s just a cheap box fan from the Big Box Home Improvement Store (BBHIS) with a cheap Heat/AC filter stuck on the back of it. It looks like this from the other side.


When the fan is running, the filter sticks to the back of it. No mechanical connection is required. This setup cost me less than $30, and it replaces a HEPA system that sells for $800…. plus $200 for each replaceable filter insert.

I know it is working because after about a month and a half, the filter looks like this…..

ewwwww…. look at that old filter. I have put a new filter down next to it so you can see the difference. Gross! That filter is supposed to last for 90 days. This is what it looks like after half that time.

We’re breathing that?


Well, I guess we aren’t breathing it any more because it’s stuck in the filter.

Oh, and here are the construction instructions…..

Go to the HarDware store and get:

  • Cheap 20″ x 20″ Box Fan – $16.96
  • Cheap 20″ x 20″ FPR 4 (MERV 8) pleated paper filters – 3 for $8.97

Directions: Turn on fan; put filter on back of fan; take care for proper air flow direction; enjoy clean air.

Even an old Software Guy can do this.
