    Alright, I just finished building it. Here is a video of the finished product. I did take it apart and took several pictures, but I am going to try to post those up later. If there are any questions then ask away.

    This is the inside of the filter housing. I used my Dremel to make channels in the wood to help direct the air flow.

    The AER1 filter had 2 tabs that had to be cut off. This is a used filter, hence its color. Not all AER1 filters are true HEPA filters, but they do make an allergen filter that is a true HEPA filter.

    This is the AER1 filter in place. It is right at 1 1/2 thick which is the same thickness of a standard 2X board.

    This is the backside of the fan. The wood has been shaped here again to help provide better air flow.


    Total cost of this was not much. Once again, like most of my projects, a large majority of the parts I already had laying around. The only things I needed to buy was the fan, and that was only $5.
