What is a good air purifier? ?

Alright I’m looking for an air purifier that does a good job of removing smoke, food, and errant smells out of the air. I’d mainly like one that removes smoke particles seeing as I am a smoker. I’d also like one that isn’t really expensive, more then likely under 200$ and one without filters. Kinda like the grills you clean on the ionic pro ones…well thanks for the help!
