True Medical Grade HEPA filter (30 sq.ft. for Jr version) and a specific types of carbon filter depending on the models. HealthMate uses 15 lbs. Activated Carbon and Zeolite filter (6.5 lbs. for Jr), HealthMate+ uses 15 lbs. Activated Carbon Impregnated with Potassium Iodide and Zeolite (6.5 lbs. for Jr), Allergy Machine including Jr version and Baby's Breath uses HEGA Activated Military Carbon Cloth, Pet machine uses 15 lbs. Impregnated Activated Carbon and Zeolite and finally Bedroom Machine uses both 15 lbs. Activated Carbon and Zeolite plus HEGA Carbon Cloth. As mentioned earlier, Austin Air purifiers utilize an all-in-one cartridge filter that would cost between $165 - 440 however if you spread across the 5 years lifespan, annual filter replacement would only cost between $33 - 88.

Overall airflow performance

Purifying coverage, Airflow and Fanspeed Probably the easiest section to differentiate between Austin Air purifiers as everything is categorized into 2 category. Starting with the wide purifying coverage, standard version has a purifying coverage of 1500 sq. ft. while Junior version is less than half of that at 700 sq. ft. On to airflow distribution, standard version has an airflow delivery rate between 72-400 cfm while junior version falls between 48-200 cfm. All Austin Air purifiers comes with 3 fanspeed without Turbo, Auto or Sleep mode.
Noise level and Power consumption As there is no sleep mode or special option that would produced softer noise, by default both standard and junior model Austin Air purifiers noise level is louder than average at all speed between 40 - 65 dB. Power consumption is on course with the airflow delivery rate with standard model requires higher power usage at an average 135 W while junior version is at an average 80 W. Taking everything into account, Austin Air purifiers noise and power consumption level is not the most ideal in its class.

Complete list of Austin Air air purifier reviewed

In no particular order, here is our most recent list of Austin Air reviews: Austin Air Babys Breath,  Austin Air HealthMate Plus,  Austin Air Bedroom Machine,  Austin Air Pet Machine,  Austin Air HealthMate Jr HM200,  Austin Air HealthMate HM400,  Austin Air HealthMate Plus Jr HM250,  Austin Air Allergy Machine Jr,  Austin Air Allergy Machine, 

Which Austin Air air purifier to go for?

It might be designed to improve on your sleep, Austin Air Bedroom Machine is by far the most powerful unit in Austin Air purifier lineup. Thanks to the powerful airflow delivery rate and unique 5-stage filtration that combines highly effective dual pre-filters (standard pre-filter, medium pre-filter), 60 sq.ft. True Medical Grade HEPA filter, a 15 lbs. Activated Carbon and Zeolite filter and additional HEGA Carbon Cloth filter. You can be sure  all types of allergens, bacteria, smoke and odors will not be able to bypass the filters. Annual filter replacement cost is the highest in the group but nevertheless it remains cost efficient due to its 5 years filter lifespan.

With the additional filters, Austin Air is the most expensive air purifiers in its lineup yet it has no improvement on the airflow output or purifying coverage. Features wise also remains the same basic 3 fanspeed and thats about it. Unless you could splash out the extra dough. HealthMate+ version would be good enough.
  • 5-stage filtration with consistent airflow and wide purifying coverage.
  • Effective trio pre-filter that would also reduce workload of HEPA filter.
  • Durable and reliable 60 sq. ft. True HEPA filter.
  • Dual chemical flirtation with 15 lbs. Activated Carbon and Zeolite and HEGA Carbon Cloth filter.
  • Premium built with powdered coated steel housing.

  • 5 years manufacture warranty for Austin Air Bedroom Machine.
  • Louder than average fan noise.
  • Wide and heavy but casters is there to support its weight.
  • Hassle filter replacement that requires replacing the filter from bottom cover.
  • No auto fanspeed adjustment, air quality monitor and sensors, timer and remote control.

The standard version of Austin Air purifier that is anything but standard. Austin Air HealthMate is our best in value air purifier that has very similar setup to Bedroom Machine bar the HEGA filter. The first-stage Large and medium particle Pre-filter would trap large to medium particles with ease while the 60 sq.ft. True Medical Grade HEPA filter withe tackle smaller micron-size particles. On smoke and odor related pollutants, you'll have the 15 lbs. Activated Carbon and Zeolite filter standing by. Beside the impressive filters, Austin Air HealthMate is also easy to use and has an impressive airflow and wide purifying coverage that is great for bedroom, kitchen and living hall. Its annual filter replacement cost is also the lowest among the standard models thanks to the 5 years filter. Very important if you plan to keep the air purifier for long-run.

The downside? For start it lacks any innovative or practical features that would make life easier such as timer, remote control or Auto mode. It's also bulky and  heavy although HealthMate Jr version would fix some of that.
  • Great for all room sizes with its comprehensive purifying coverage.
  • Trio pre-filter (outer mesh, pre-filter, medium filter) that reduce the workload of the HEPA filter.
  • Highly effective 15 lbs. Activated carbon zeolite filter.
  • Comprehensive 60 sq. ft. HEPA filter.
  • Durable and sturdy powdered coated steel.
  • Up to 5 years filter lifespan.
  • 5 years manufacturer warranty.
  • Loud fan noise with no option of silent/ sleep mode.
  • Very bulky and heavy despite having a casters to support.
  • Hassle filter replacement that requires filter to be unscrew from the bottom.
  • Slight innovative features such as auto mode, digital screen, air quality indicator,/ sensor, timer.

Great for allergies and asthma sufferers, as the name clearly suggested Austin Air HealthMate Plus is the enhanced version of HealthMate with special focus on removing Formaldehyde, Ammonia and VOCs. Formal and Ammo what you might ask. In simple search you will know that these 2 colorless, strong smelling gas actually dispersed through off-gassing from common household product and building material such as carpets. wooden floor tiles, furniture and more.  HealthMate Plus 15 lbs. Activated carbon zeolite filter comes with additional additive of potassium iodide that would take care of those unwanted smell with ease. The air purifier would work particularly well in paint shop, salons or new/ remodeled home.

As HealthMate+ shares the same exact design and airflow efficiency as all Austin Air standard unit, it do suffers from the same lack of modern features and even more costly price tag. Again there is also Austin Air HealthMate+ Jr which is essential the "compressed" version of it.
  • Great for all room sizes with its comprehensive purifying coverage.
  • Trio pre-filter that reduce workload of the HEPA filter.
  • Highly effective 15 lbs. Activated carbon zeolite filter with impregnated potassium iodide.
  • Standard but proven 60 sq. ft. HEPA filter.
  • Durable powdered coated steel housing with zero off-gassing.
  • Super long filter lifespan of up to 5 years.
  • 5 years manufacturer warranty.
  • Undesirable noise level particularly on higher speed.
  • Bulky and heavy although there is a caster to support.
  • Hassle filter replacement that requires unscrewing the bottom part cover.
  • Very empty on spec- lacks auto mode, indicator, air quality sensor, timer and remote control.

For smokers and chemicals sensitive person like myself, Austin Air Allergy Machine is your best bet against allergens and odors irritants. Needless to say smoke and chemicals emitted from cigarettes, cigar and other products are hazardous and have adverse effect to your health. Activated Military Carbon Cloth HEGA filter will act as a last line of defense in Allergy Machine that captures them thus preventing  the allergens from reaching to you. So should I go with HealthMate + Allergy Machine? So beside the deodorization filter and Allergy overall lighter weight, you can see there is little differences between HealthMate+ and Allergy Machine so either one would do a great job against chemicals.

Again we are highlighting the same problems, the lack of timer, digital display, air quality sensor, Auto mode could be Allergy Machine biggest setback. If you do not need the high airflow performance, go with Allergen Jr as it is cheaper and more compact.
  • Activated military grade carbon HEGA filter that is great for people that are sensitive to allergens.
  • Consistent airflow with wide purifying coverage.
  • Comprehensive filtration thanks to the trio pre-filter and reliable 60 sq. ft. certified HEPA filter.
  • No off-gassing as the exterior is made entirely from powdered coated steel.
  • Long-life (up to 5 years), low maintenance cost filter.
  • 5 years warranty.
  • Clearly audible noise level that is not great for night use.
  • Lighter but overall still bulky that requires casters support.
  • Hassle filter change from bottom rather than pop out cover.
  • Empty on features. Lacks auto/ sleep mode, air quality sensors, digital screen indicator and timer.

Excellent for pet owners, Austin Air Pet Machine is another alternative to HealthMate+ and Allergy Machine that shares the same design, airflow output and purifying coverage. Designed to remove pet hair and odors via its pre-filter, medium filter, HEPA filter and specially formulated 15 lbs. Impregnated Activated Carbon and Zeolite filter. Other than that, Pet Machine is pretty much the same 4-stage filtration air purifier which by no mean it's a bad thing. Unless you have indoor pets with unbearable stench, we reckon HealthMate Plus would do just fine.

Instead of us repeating again, refer to the previous list on the common downsides in Austin Air purifier or go to the product review page. Unlike most standard air purifier, there is no Pet Machine Jr version to opt for.
  • Extensive purifying coverage for pet and non-pets owner.
  • Dual first-stage filtration (Outer mesh filter and large particle pre-filter) in trapping pet hair.
  • 15 lbs. carbon filter with zeolite and special additive ammonia designed to absorb ammonia and pet odors.
  • Double filtration (medium filter + 60 sq. ft. HEPA filter) for medium to smaller size particles.
  • Durable coated steel housing with zero off-gassing.
  • Super long filter lifespan of up to 5 years.
  • 5 years manufacturer warranty.
  • Undesirable background noise level on all speed.
  • Bulky and heavy although there is built-in casters.
  • Hassle filter replacement that requires flipping over the machine to remove bottom cover.

What something less bulky, pricey yet still have the capacity in eliminating those pesky allergen? Oh ya it has to be in Pink too, then Austin Air Baby's Breath is your answer. Technically a replica of Allergy Machine Jr, Baby's Breath has the same dimension, airflow performance, controls, filtration and filters setup with the exception of its light Pink or Blue color option. Annual filter replacement cost is very cost-efficient across 5 years lifespan as with every other junior models.

If you dislike the lack of practicality functions and controls from Allergy Machine Jr or in fact any other Austin Air purifiers, Baby's Breath unfortunately replica the same downside as well. It's also not the cheapest so do compare with other Jr model first before purchasing one.
  • Wide purifying range despite the smaller size.
  • Dual side-by-side pre-filters that prolong HEPA filter lifespan.
  • Effective and often underrated medium filter plus 30 sq.ft. HEPA filter.
  • Activated military carbon HEGA filter that is great against bacteria and tobacco smoke.
  • Quality powder coated steel housing with no plastic off-gassing.
  • Long-lasting Austin Air filter that could last up to 5 years.
  • 5 years manufacturer warranty.
  • Noise level is relatively high especially on the third fan speed.
  • Heavy yet without casters support (requires additional purchase).
  • Hassle filter change that requires unscrewing the cover.
  • Empty on features - lacks auto mode, digital screen, air quality sensor, timer and remote control.

Why Austin Air’s purifier does not have a filter indicator light to aler you when filter requires replacing?

Because of the inaccurate filter usage measurement does not justify the cost of the addon on Austin Air’s purifier. There are 3 options of calculating the filter lifespan. First and the most common option is a simple timer to keep track of the length of time the filter is used. Highly inaccurate as the medium particle pre-filter, activated carbon and medical grade HEPA filter have different purpose so their usage lifespan would vary too. The second option is to measure the pressure drop across the filter until certain pressure of drop is reached. Again, this method is inaccurate as the filter is often more dirtier to the point it is unusable then the pressure drop suggested. Third option is to monitor the vapor pollution level of the air until it exceeded a certain level. This method is the most accurate and unfortunately it is the costlier that if implemented, it will push the selling price much higher and is no good news to the purchaser.
