Key Differences Between AirDoctor and Austin Air

While AirDoctor and Austin Air both use proven HEPA filtration to capture airborne particles, they differ in their approach to air purification:

AirDoctor Air Purifier
  • UV-C Sterilization – The AirDoctor’s key differentiating feature is its patented SterilRayTM UV-C light technology. The ultraviolet light works to sterilize and deactivate airborne viruses, bacteria, and mold spores as air passes through the purifier. Austin Air relies solely on mechanical HEPA filtration without UV sterilization.
  • Activated Carbon – Both air purifiers use activated carbon filters to adsorb odors, gases, and VOCs. However, the Austin Air has around 60% more activated carbon than the AirDoctor.
  • Coverage Area – The Austin Air HealthMate Standard can handle larger rooms up to 1500 sq ft while the AirDoctor is rated for spaces up to 1100 sq ft.
  • Noise Level – The Austin Air operates more quietly with noise levels as low as 20 dB on the lowest fan speed. The AirDoctor generates more audible white noise ranging from 32 – 55 dB on different fan speeds.
  • Design – The AirDoctor has a more compact, cylindrical design suited to blend into room decor. The larger Austin Air unit has a square-shaped industrial look.
  • Warranty – Austin Air provides a longer 5 year limited warranty compared to AirDoctor’s 1 year warranty.

Air Purifier Reviews: AirDoctor Pros and Cons

AirDoctor air purifiers are designed and engineered in Israel, home to some of the world’s leading UV technology experts. Here are the key pros and cons of the AirDoctor’s features and performance.


  • Medical-Grade Filtration – The 4-stage filtration uses an H13 HEPA filter that removes 99.97% of particles larger than 0.1 microns such as dust, pet dander, smoke, and mold.
  • UV-C Sterilization – The SterilRayTM technology kills up to 99.9% of viruses, bacteria, fungi, and more according to lab testing. UV-C light destroys microorganisms and prevents them from replicating.
  • Odor Reduction – Activated carbon filter adsorbs VOCs, smoke, and stubborn pet, cooking, and chemical smells.
  • Auto Mode – AirDoctor automatically monitors air quality and adjusts fan speed accordingly to filter and circulate air.
  • Compact Size – At 16.5 inches tall, the AirDoctor can fit in corners and smaller spaces while still handling rooms up to 1100 square feet.
  • Quiet Operation – AirDoctor runs as low as 32 dB on the lowest fan speed so you can comfortably sleep or work.


  • No Timer – Lacks on-board timer to schedule when the purifier turns on/off.
  • MediocreCADR Rating – Clean air delivery rate of 240 cubic feet per minute is decent but lower than other brands.
  • Limited Air Changes per Hour – Can exchange air in a 889 sq ft room 2.5 times per hour on highest speed. Other models offer higher air changes.
  • Minimalist Controls – Has a simple on/off button and fan speed dial rather than advanced LCD displays offered by competitors.

Austin Air HealthMate Pros and Cons

Engineered in America, Austin Air purifiers have been around for over 25 years. Here are the notable pros and cons of the Austin HealthMate model:


Austin Air Purifier
  • Large Carbon Filter – It contains over 15 lbs of activated carbon, more than most other brands, allowing for superior gas and odor removal.
  • Extremely Quiet – The large activated carbon filter diffuses airflow to produce quiet operation as low as 20 dB even on high speed.
  • High CADR Rating – With a clean air delivery rate of 350 cfm, it can filter high volumes of air quickly.
  • Medical-Grade Filtration – True HEPA filter removes 99.97% of particles down to 0.3 microns in size.
  • 5 Year Warranty – Backed by one of the longest warranties among major air purifier brands demonstrating durability.


  • No UV or Ionization – Lacks UV sanitization or ionizer found in other air purifiers for reducing viruses/bacteria.
  • Big and Bulky – Large square design takes up more floorspace. Dimensions are 23 x 14.5 x 14.5 inches and 18 pounds.
  • Manual-Only Operation – No smart sensors or auto mode. Fan speed must be adjusted manually.
  • Higher Maintenance – Large HEPA filters plus 15+ pounds of activated carbon means higher ongoing filter replacement costs.
  • Airflow Direction – Air enters and exits from the side rather than the top, which is less effective for air purification throughout a room.
