The majority of the unit is built out of 3/4 birch plywood with poplar “trim” and doors. The fan is plugged into a switched outlet on the interior of the unit. The decora switch is located on the bottom center, within easy reach with a push stick. I put felt insulation around each of the filters, the fan exhaust port and the hole for the romex. The filters are tilted at a 32.5 degree angle to reduce the height of the unit (by a bit) and help with air intake. Lowes started to carry 10×20 filters (merv 6) which also helped keep down the size.
The squirrel cage blower only moves 180 CFM (cubic feet per minute). The basement is 22’ by 22’ and is just over 8’ to the floor boards which puts the “full clean” at about 20 minutes. A laundry room is going to be carved out in the corner (sealed as best as we can), taking out about 450 cubic feet. Plus the main work area in located around the filter, so most of the dust will be right near the filter. My hope is that is will clear the air in more like 10 minutes. I did have it on while I was sweeping up and the pre-filter was visibly dirty. We will see.
I have not done anything to finish it yet. Not sure if I will stain or just poly it. I am more than happy to put it to a vote.
