Austin Air HM-250 Air Purifier Review

The Austin Air HM-250 is one of the most recommended air purifiers by medical professionals for patients who have problems with allergies. This model features the use of a medical grade True HEPA filter, which eliminates as much as 99.97% of airborne germs. In addition, it includes a secondary carbon and zeolite with potassium iodide filter which is extremely effective in removing odors and gasses. Probably the best feature that this model has is the 360-degree intake system which draws air from every side of the machine, allowing complete and maximum air cleaning.

4 Stage Filtration Technologies

Permafilt Pre-Filter

Stage 1: Large Particle Pre-filter

This is a reusable and cleanable pre-filter which removes particles which are large enough to be seen by the naked eyes, for example, human hair, dust, and pet dander. This Stage 1 pre-filter is easy to maintain by simply vacuuming it clean once a month to ensure quality filtration. Over time, you can also replace this filter as a set together with the HEPA filter.

Main HEPA Filter

Stage 2: Medium Particle Pre-filter

The medium filter removes medium size particles including mold, spores, and pollen.

Stage 3: 6.5 lbs of Carbon/Zeolite with Potassium Iodide

The Activated Carbon/Zeolite with Potassium Iodide is highly effective in absorbing unwanted odors, gasses, and dangerous chemicals (VOCs) in your home. The Potassium Iodide acts as an additional filter which kills any other odor that the Carbon is unable to remove. This super blend of Carbon and Potassium Iodide makes the HM-250 a perfect choice for those who have allergies to chemicals.

Stage 4: 30Sq ft Certified True HEPA Filter Media

This is a medical-grade true HEPA filter which takes out 99.97% of all particles that are any larger than 0.3 microns. This HEPA filter can last up to 5 years, making this machine one of the most cost-friendly air purification systems on the market.
