/diy/ - Do It Yourself

I don't usually post on this board. I saw this thing and made one using furnace filters and a box fan. I second the other folks who say wipe it all down- I'd vacuum first, then wait, then wipe it down.

Thanks. I feel this design generates almost no strain on the fan and allows for the air to be distributed evenly on a room.

One of the issues I saw with some of the designs posted here was that the output was very directional (to a side), while this design pushes the air upward and down, pushing dust, pollen, etc into the filters for cleaning.

The fan is not attached and it works great. Anothr big advantage is being able to tape the corner of a scented drier sheet inside (the center of) the bottom, and have clean and nice smelling air blowing out the top.

I actually ended up using 3 filters. One 20x20x1 and two 12x12x1 (measurements in inches). 3 large filters could have been an overkill.
They are all HEPA grade that filter pollen (the large one even filters odors).

On this picture, you can see a badly taped bottom. That's because is a second bottom just to provide structural integrity to this prototype (aka: make the box sturdy). The first bottom is completely sealed (duct tape of course).
