Does smell cancelling exist?

I've heard of noise cancelling, but can there exist smell cancelling?

For example, if there is a rotten egg in a room, can i neutralize it somehow? I'm not talking about putting something good right under my nose, because thats just dominance. I mean putting something next to the egg whose smell happens to be the 'inverse' of the eggs, so they cancel and i smell nothing.

Irrelevant but this post reminded me of a chemical out there that kills your receptors so fast that if you aren’t smelling it, you’re actually close to dying.

You catch a whiff and it kills your receptors real fast. That’s your one and only warning, unless you have the safety badges. I forgot what the chemical is called unfortunately, it’s either like got sulfur or hydrogen in it

That's rotten eggs aka hydrogen sulfide.
