I'm debating between the Austin Air Immunity, Bedroom or Healthmate Plus. Can someone with any of them help me decide? Is it worth it to go with the Immunity or will I be fine with the Healthmate Plus? I realize this is subjective but would love to hear your own personal experiences.

Room is about 700 sq ft. Need to filter VOCs, car exhuast/pollution. I already have an IQAir Healthpro Plus but it doesn't seem to deal with VOCs/car exhaust as well. Also, it sucks air from the bottom and the Austin one sucks air from 360 degrees so I'm curious if that will work better for me. Open to your thoughts. THanks!
