Filtered Positive Pressure To Keep Dust Level Down

Jeezo, every drawer, toothbrush, dishes, even a bar of soap gets polluted. When it gets bad, the dust goes into the refrigerator. Bedding has to be taken outside, hung then whacked. I keep clothes in doubled lawn & leaf bags with two ties. A pail of water used with a rag soon turns to mud :(

I was thinking of something like a giant K&N filter to stop a lot of the dust covering a large HEPA 2 type filter. The foam can be washed and re-oiled, and the HEPA can have high pressure air blown in reverse to recover a few times. A gigantic big rig filter would work but they have an obnoxious chemical smell.
