Vaporizing H202 for container, chamber, glove box sterilization?

I don't know how stable H202 is when vaporized by a humidifier, maybe a chemist who knows can chime in?
I thought it would be a good idea to fill a humidifier with hydrogen peroxide solution and pipe the vapor into the container, glove box, or fruiting chamber effectively sterilizing every nook and cranny.
I know that H202 is not very stable and might decompose in the ultra sonic vaporizer?

no, we dont'need the sab to be sterile we need it to be still, pumping air in would ruin that just get your sab wet and sanitize your jars and what not

 As long as you have proper sterile techniques, like spraying down the entire box with soap water and letting it sit for a few minutes, not touching the rim of any exposed jars, not having your hands hover over any exposed plates, flame sterilizing, etc., your jars will be okay and you'll have a very low rate of contams.
Here's a good writeup on sterile techniques http://www.shroomery.org/forums/showflat.php/Number/21889950/fpart/all/vc/1

Ok, but I still really want to know because it has more uses than just the glove box.
Will the hydrogen peroxide remain intact after vaporization. Can the vapor produced from hydrogen peroxide be used to sterilize a surface or air?

i'm going on a hunch here but no, it breaks down fast in the presence of oxygen and light which is why it's in a dark bottle but wait fro someone else i guess

You don't even need the hydrogen peroxide, and definitely don't vaporize it, that's just silly. Use isopropyl alcohol to sanitize the surfaces of your jar lids. That's it. The rest is just making sure your tools are flame sterilized before using. Oh, and your SAB should be wet inside, you want contams to stick to the sides of the box.
Here's mine:

I doubt you can even get it to boiling without exponentially speeding up the rate at which it turns to water.

H2O2 is unstable with light, heat, exposure to air and time - just like ozone.
Follow standardized procedures. No need to reinvent the wheel.

This is a common technique utilized in clean rooms and other applications. It poses serious risks and requires proper engineering to ensure safety.

Wiki article suggests that it does work.
This application might be able to be used to help sterilize an occupied fruiting chamber if early signs of pathogens are present, or just routine prevention of pathogens. I'm not looking to just sterilize a glove box.

Its not boiling, its passing the h2o2 solution over a sonic vaporizer to produce a fine mist fog

Chemicals sanitize, heat and filtration sterilize.
There is no need for peroxide in this hobby outside of treating cobweb mold.

Wouldn't it be easier to just boil some water and pipe the steam in to sterilize it if you wanted to do that? Hydrogen peroxide vapor can be dangerous. I also think all the moisture has to be removed from the air first to even produce it.

Hospitals use peroxide vapor to "sterilize" rooms. Though it's chemical it achieves near sterilization on already mechanically clean surfaces. It's not peroxide in any concentration you can buy and if you could you don't have the special fogger and if you did you would probably kill yourself. Peroxyacetic acid sanitizer achieves near sterilization on cleaned stainless steel surfaces but its also nasty shit.
Rely on technique not chemical bullshit. Quit trying to cut corners OP
In Japan back in the day they put a beaker of formaldehyde on a hot plate to fumigate a whole room to sanitize/sterilize it.
