I am building an air filter box frame which will mount a total of 4 20x20x1 filters. Each filter will be mounted on one of the 4 sides of the box; the top and bottom of the box will have supporting plywood plates. One side will also have a box fan mounted on it. Right behind the fan, the filter will be of a lower Merv rating in order to allow sufficient air passage.
The frame was cut with a cnc router, and the pieces fit together really well. They are 3/8 MDF to keep it light.
I am not sure how to square it, given that it's such a big box. The pieces all snap together tightly, so clamping the box is not necessary.
This is a prototype for a large room almost hepa air cleaner, featuring 3 Merv 13 filters, one Merv 8 with an easy to attach box fan in front. It will also have casters on the bottom.
Where I live, we can get a month of smoke from forest fires. If this works well, I may want to build them for the community. The assembly method, therefore, should be almost foolproof.
Once it's built and tested, I'll be happy to send anyone interested my dxf files.
Given the cost of air filters, if this design works, the total cost will be 1/5 of a commercial unit.
I now need some advice on squaring it.
thanks
tony
