AllerAir vs Austin Air

A good air purifier needs to address the indoor air pollutants that you are most concerned about and have a filtration system that will eliminate those pollutants. 

Two of the best on the market to take aim at pollutants are Austin Air and AllerAir. Both provide you with robust air purification systems that have HEPA and carbon filtration. These will get rid of pollutants in your home ranging from smoke to VOCs to allergies and more. 

Why are Austin Air and AllerAir to be trusted you may ask? 

Both companies have over 25 years in the air purification industry.

Austin Air has been manufacturing medical-grade HEPA air purifiers since 1990 and has worked with FEMA and the American Red Cross. Austin's air purifiers have also been proven to remove pollutants in independent clinical trials done

AllerAir, in business since 1996, was started by Sam Teitelbaum who developed an air purifier to help a family member suffering from MCS (Multiple Chemical Sensitivity). He developed air purifiers not only to remove particles but also airborne chemicals and odors. 

Both have become industry leaders and experts in the field of air purification. 

If both are such great air purifiers, what are the differences between them? 

Wellness Junction wants to show those differences so you can make the best decision when making your purchase of an air purifier.

AllerAir Air Purifiers vs. Austin Air Purifiers — What's the Difference?


The price range between the two are very similar. Both are top brands with great results for over 25 years.

AllerAir ranges from $599.98 - $1,199.98 and Austin Air range from $714.99 - $994.99

The upgrades for the AirMedic Pro 5 and 6 Series are: UV light adds another $150.00 and the VOCARB carbon filter adds another $50.00. 


AllerAir — With a regular 3-stage filtration system and the option to upgrade to a 4th filter (UV light), AllerAir has one of the best carbon filters on the market. 

The first line of defense is the pre-filter that removes larger particles.

The carbon filters, ranging from  2.5" - 5" deep, are industry leaders for the deepest carbon filters on the market. The normal carbon filter blend is EXEC which is for standard air cleaning. The option to upgrade to the VOCARB blend is for higher pollution levels, VOCs, chemicals, fumes, and odors.

It also comes with a medical-grade HEPA filter that removes 99.97% of all airborne particles 0.3 microns in size.

The upgrade to a UV light (+$150) is an option that Austin Air doesn't have. UV light can neutralize airborne germs, larger viruses, and mold spores.

Austin Air — The HealthMate has 4 levels of filtrations with 2 pre-filters (medium and large particles), a medical-grade HEPA, and an activated carbon filter that has 15 lbs. of activated carbon and Zeolite. 

The carbon filter mix of activated carbon and Zeolite gives you great protection from gases, odors, and chemicals. Zeolite, a natural mineral, is particularly effective in adsorbing formaldehyde, ammonia, and carbon monoxide.

The HEPA filter, at 60 sq. ft., is an industry leader that removes 99.97% of all particles larger than 0.3 microns and 95% of all particles larger than 0.1 microns.

Overall, you cannot go wrong with either brand's filtration system. Both are very similar but the one thing that differentiates is how long the filters last. For AllerAir, you will have to replace each one separately and at different times. Austin Air's whole filtration system has a 5-year life expectancy. No one can beat that. 

Aller Air Filter Life Expectancy Austin Air Filter Life Expectancy
Carbon Filter — Every 2 - 5 years
HEPA or Super HEPA — Every 2 years
Pre-filter — Every 3 months
UV light — Annually
Carbon Filter — 5 years
HEPA Filter — 5 years
Pre-filters — 5 years

Housing Material

AllerAir — The metal housing is designed with powder-coated paint to prevent any off-gassing which is very important. Some air purifiers made of plastic can off-gas which emits harmful chemicals. One of the only plastic parts on the unit is the caster wheels that allow you to easily move it around your home. 

Austin Air — The housing is made of solid steel and welded together to prevent any rattling. The powder-coated paint will prevent any off-gassing and odors like AllerAir. Similar to AllerAir, one of the only plastic parts on the Austin Air unit is the plastic caster wheels. The only other plastic parts are the fan blade and control knob. 

Noise Level

Nobody wants a loud air purifier that overbears them when it is running 24/7. Both AllerAir and Austin Air have units that can be a bit loud on the highest setting but not unbearable. 

Austin Air says that depending on the fan setting used, the noise level ranges from less than 50 to around 62 dB (decibels). This is the sound of a whisper to the sound of a normal conversation.

AllerAir has units that range from 45-62 dB depending on what speed the air purifier is set to so this is very similar to Austin Air. 


The warranties for both brands are very good and you will be covered for 5 years and more.

Austin Air — The air purifiers are warranted to be free from defects in material and workmanship for five (5) years from the date of purchase and a five (5) year pro-rated filter warranty, by far the most comprehensive in the industry. If the filter lasts less than five years, Austin Air will discount the cost of a new filter based on the number of years the filter has been in use.

AllerAir — The air purifiers are covered by a 5-year warranty on labor as well as a 10-year warranty on parts (motor, cord, switch, wheels, etc).
