We carry two brands, Austin Air and Airpura, because we believe they are the two best air purifier manufacturers in the world. Both use True HEPA filtration, substantial activated carbon, all-steel construction, and zero ionizers or ozone.
So how do you choose between them?
The Short Answer
Choose Austin Air if you want a proven, straightforward purifier with a long track record, clinical research backing, and a single filter that handles everything for 5 years.
Choose Airpura if you have specific contamination needs, chemical sensitivity, or want to select from a wide range of specialized filter configurations.
Austin Air: The Clinical Standard
Austin Air has been manufacturing air purifiers in Buffalo, New York since 1990. Their purifiers have been deployed by FEMA during disaster response, used in VA hospitals, studied in clinical research at Johns Hopkins University, and trusted by allergy and asthma specialists for over three decades.
Every Austin Air purifier uses the same core approach: a 360-degree intake that draws air through a pre-filter, then through a bed of activated enhanced carbon, and finally through a True HEPA filter. The entire system is sealed in a welded steel housing.
What sets Austin Air apart:
- 15 pounds of activated enhanced carbon per unit
- 5-year filter life rated at 8 hours per day of use
- 360-degree air intake for whole-room filtration
- Studied in peer-reviewed clinical research
- Simple single-filter system with no complicated maintenance
Austin Air lineup at a glance:
HealthMate: the original. True HEPA plus 15 lbs of activated carbon for particles, gases, and odors. Best all-around choice for most homes.
HealthMate Plus: same 15 lbs, but part of the carbon is chemically treated to target formaldehyde and other VOCs that plain carbon holds poorly. Best choice for wildfire smoke, chemical exposure, and off-gassing. The two are compared in detail in HealthMate vs. HealthMate Plus.
Bedroom Machine: a five-stage machine built for nighttime air quality, adding a medical-grade HEGA carbon cloth on top of the standard bed. This is the model Johns Hopkins researchers used in their home air quality studies.
Immunity Machine: built around allergen and pathogen reduction with a medical-grade HEPA and carbon combination.
HealthMate Junior: the same filtration approach scaled to rooms up to 700 sq ft, for bedrooms, nurseries, and offices.
Airpura: Built for Chemical Sensitivity
Airpura has been manufacturing air purifiers in Montreal, Quebec since 2004. Their focus has always been on the most demanding air quality needs, specifically people with Multiple Chemical Sensitivity (MCS), healthcare facilities, and laboratories where contamination tolerances are extremely low.
Every Airpura purifier is built with a powder-coated steel body, off-gas-free internal components, and a sealed system designed to prevent any secondary chemical exposure from the purifier itself.
What sets Airpura apart:
- 26+ filter configurations for targeted contamination control
- Powder-coated steel body, no plastic off-gassing
- Off-gas-free internals, safe even for the most chemically sensitive
- Covers up to 2,000 square feet in larger models
- 400, 600, and 700 series available
Airpura series at a glance:
R Series: heavy activated carbon for gases, VOCs, and wildfire smoke. The R600 is one of the most popular purifiers for wildfire protection, and we cover that use case in the best air purifier for wildfire smoke.
C Series: maximum carbon configuration for chemical sensitivity and VOC-heavy environments.
F Series: formaldehyde-specific filtration for new construction, renovations, and furniture off-gassing.
P Series: designed for healthcare environments, targeting airborne pathogens.
Airpura builds 58 machines across these letters and three size classes. If the model names are what is holding you up, we decode the whole system in Airpura 400 vs. 600 vs. 700.

Our Recommendation
If you are buying your first serious air purifier and want a proven all-around performer, start with the Austin Air HealthMate or HealthMate Plus. It is simple, effective, and backed by more clinical research than any other purifier on the market.
If you have Multiple Chemical Sensitivity, live in an area with heavy chemical exposure, or need a specialized filter configuration for a specific contaminant, Airpura is the right choice.
Both brands carry the full manufacturer warranty and ship free to all 50 states. Every order is covered by our 30-day home trial, and if the machine is not right we pay the return shipping.
