Purifiers are all about the filters, anything else is pretty much just marketing BS. On that note, Ikea has some air purifiers[0] that aren't very expensive and use HEPA filters with optional carbon filter to remove smells. They have basic ones and 'smart' ones in different form factors (even one that is a table!). We have cats and it really helped removed the cat smell from out house.
