Juvenile question: if underwear were made from HEPA filters, could you fart and have it not smell?

You'd need an airtight seal. It could still leak out of the leg holes and the crotch. It would also stain easily.

So, basically your underwear would either inflate or have to be tight enough to force the gas through the filter if it were sealed at the waist, legs, and crotch?

HEPA filters are not efficient at filtering molecule sizes typical of VOCs (volatile organic compounds). For gaseous odors you would need a chemical ad/ab/sorption process (i.e. activated charcoal).

I was JUST going to post that.

What he says is correct. HEPA filters are no good at removing smells. For that you need an activated charcaol filter. That's why many air cleaners have both.

HEPA filters are measured in microns, molecules like methane are measured in angstroms. That 6 orders of magnitude smaller (base 10). But I like the way you think:) Good imagination.
