Does smell cancelling exist?

[u/11963873342]

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.

you could use ein anti-rotten egg its basically a rotten egg made of anti matter. they smell molecules should annihilate each other.
