I have a small ozone generator that I use in the house to neutralize odors, and it does a wonderful job at that. For those of you who are not familiar with ozone, it is a molecule with an extra oxygen atom (O3), making it very reactive and consequently useful in a variety of antimicrobial tasks ranging from air purification to water purification and even certain medical treatments (I have another, medical-grade ozone machine that I have used on myself for treating Lyme disease - but that's another story).
So I got to thinking about my still air box and my desire to make certain that there are no stray germs or mold spores present when I use it, and I decided to utilize my ozone generator. I bought a small air filter from Ace Hardware that is rated for filtering mold spores, cut it out of its frame, carefully removed the metal reinforcing mesh, and placed a piece over the air intake on the ozone generator.
Then I traced the outline of the front of the generator onto the side of my plastic tub SAB and cut it out using a hot knife blade. I taped over the edges of the exterior of the opening with a 1/8 inch overlap so that when I put the front of the generator through it, the tape would provide a good seal.
I cleaned the interior of the SAB using IPA as usual and put the lid on, then ran the ozone generator for about a minute so it could fill the SAB with ozone. I turned off the generator (while leaving it in place) and covered the arm openings on the front of the SAB to seal it from outside air. After a few minutes to let the ozone in the SAB do its' anti-microbe thing I uncovered the arm openings and used the SAB in normal fashion, with greater confidence that the air inside of it was free of unwanted microscopic critters.
Ozone gets a bad rap as a deadly gas but that is only in very high concentrations, which is not what a home ozone generator can create. Still, if you breathe the ozone from directly in front of the generator it can irritate the lungs, so one must use common sense. The little bit of ozone that would come out of the arm holes while using the SAB would not likely be an issue. Here is the unit that I use for air purification: https://www.amazon.c...e?ie=UTF8&psc=1
So for whatever it may be worth...
