If you’re looking for a heavy-duty air purifier, look no further than the Healthmate HM-400 from Austin Air. Weighing in at 45 lbs, it comes fully equipped with a 4-stage filtration system which includes a large particle pre-filter, medium pre-filter, activated carbon filter, and a True HEPA filter. These filters are guaranteed long life and only need to be changed every 5 years which effectively cuts maintenance costs for the HM-400.

Judging from how much activated carbon this air purifier has, you can immediately tell it was designed to target all kinds of airborne pollutants, as well as harmful odors, gases, and chemicals. If you live with several smokers and need a powerful air purifier to minimize the spread of secondhand smoke, then the HM-400 would be your best bet. In addition to its excellent performance with odors and VOCs, the HM-400 is capable of covering spaces of 1,500 sq. ft. at 1 complete air change per hour with 3 different fan speeds.

Unfortunately, such high performance and power comes with a high price as well, therefore, the HM-400 is definitely one of the more expensive air purifiers available in the market. What’s more, even at this price point, it lacks several features such as air quality and filter change indicators, as well as smart modes which are present in many air purifiers half its price. It’s also extremely large and heavy, with a design that isn’t very aesthetically pleasing; although, it does have casters for easier mobility.

However, despite these flaws, no one can deny that the HM-400 is on a whole other level when it comes to removing airborne pollutants at home. If you’re looking to cover a large area and don’t mind the hefty price tag, then go ahead and treat yourself to an HM-400.
