Alot of junk out there so thinking your cleaning the air effectively with a $100 unit is hilarious. You might filter more dust but not the particles you may really need. Products like Amaircare can be attached to your entire hvac and clean all the air multiple times an hour depending up on the size. Other room purifiers can target specific things like chemicals, dander, and dust but these units cost more because you get what you pay for. If you worked in a salon or paint store all day long, there is a lot of stuff floating around. Better units have very good filter(s) which is the difference.
