What is the opinion of Reddit about the
Zmenaren Air Purifier for Home,Pluggable Mini Smoke Purifier Odor Eliminator to Pet Smell,Dust and Cigarette Smoke for Home & Office, Green+Pink?

There are some plug in scent devices that will cancel the smell of cigarette smell.

Here’s an example:

But there are different brands as well.

Here’s another one:

I think there’s two types, one uses small perfume bottles that need replacing once every few weeks, the other uses Ozone. And you can also get both and then combine their functions.
