Austin Air HealthMate HM400 (B400)

Pros

  • About 15 lb of carbon and zeolite
  • Filter rated for up to 5 years
  • All-steel construction
  • No ionizer

Cons

  • Loud at its lowest speed
  • Low particle CADR for the price
  • High power draw
  • Very expensive, with no sleep mode or app

A niche choice for persistent, heavy odor in a living area. For most homes, a cheaper machine with an upgraded carbon filter is the more practical route.
