Which Austin Air air purifier to go for?

It might be designed to improve on your sleep, Bedroom Machine is by far the most powerful unit in the lineup. All thanks to the powerful airflow delivery rate and unique 5-stage filtration. It combines highly effective dual pre-filters, 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. Filter cost is the highest in the group but remember, it will last up to 5 years with 12 hours of operation.

With the additional filters, Bedroom Machine is the most expensive in its lineup yet it has no improvement on the airflow performance. Features wise also remains the basic 3 fan speed with nothing to shout about. Unless you are willing to splash out the extra dough. HealthMate+ would be good enough for most.

  • Effective trio pre-filter that would also reduce workload of HEPA filter.
  • Durable and reliable 60 sq. ft. True HEPA filter.

The downside? For start, it lacks any innovative or practical features. A timer, remote control or Auto mode would really be helpful. It's also bulky and heavy although HealthMate Jr version would fix some of that.

For smokers and chemicals sensitive person like myself, Austin Air Allergy Machine is your best bet. It is designed specifically to fight against allergens and odors irritants. Let's skip the medical-grade HEPA filter that we all know what it is all about. Instead, focus on toxic fumes emitted from cigarettes and cigar. It is hazardous where prolong exposure will have an adverse effect on your health. Allergy Machine specially made Military Carbon Cloth will protect you from the smoke allergens without fail. Same applies to the Jr version if you want something identical but cheaper.

Beside the deodorization carbon filter, there is little differences between Austin Air purifiers. The lack of a timer, digital display, air quality sensor, Auto mode is still here. There is also no upper hand on Allergy machine airflow performance. Consider this if you are a hypersensitive person.
  • Activated military grade carbon HEGA filter that is great for people that are sensitive to allergens.

As the name suggested, Austin Air Pet Machine is a specifically made for pet owner with indoor dogs or cats. Designed to remove pet hair and odors via its trio filter and specially formulated 15 lbs. Impregnated Activated Carbon and Zeolite filter. If you are constantly harassed by pet allergens, this is the perfect go-to model. Other than that, it is pretty much the same HEPA air purifier which by no mean it's a bad thing.

Unless you have pets with unbearable stench, we reckon HealthMate Plus would do just fine. On paper, it is identical to other Austin Air purifiers with no modern purifying technology. Unlike other standard versions, 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.

What something less bulky, pricey yet still have the capacity in eliminating pesky allergens? Oh ya, it has to be in Pink too, then Austin Air Baby's Breath is your answer. A replica of Allergy Machine Jr, Baby's Breath has the same dimension, airflow performance, and filters setup. Its unique selling point is purely cosmetic with additional light Pink or Blue color option. Annual filter replacement is of course very cost-efficient across the 5 years lifespan.

If you dislike the lack of practicality functions from any other Austin Air purifiers, no exception with this baby. It's also not the cheapest compared with other Jr models. If you really want a pink or blue color option, this it the price you have to pay.

Not the most accurate method as the medium pre-filter, activated carbon and HEPA filter have different usage lifespan.
