Austin Air Allergy Machine review

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.

The starters

Dimension

14.5 x 23 x 14.5 in

(36.8 x 58.4 x 36.8 cm)

Weight

33.1 lb (15 kg)

Austin Air Allergy Machine boxy exterior has the exact same dimension with every other Austin Air air purifier at 14.5 x 23 x 14.5 in. Weight is slightly lighter at 33.1 lb, you would still need to rely on the 4 casters to move the air purifier around. Usability is a bit of mix bag; front dial knob fan speed is super easy to use however, the lack of any practical features such as air quality sensor, auto mode, filter indicator hinder the air purifier overall usability. On to the specification, what’s included in the package is a 4-stage filtration, 5 years all-in-one filter lifespan, 360° progressive Intake System, NRTL (Nationally Recognized Testing Laboratory) recognized, CSA (Canadian Standards Association) and CE (Conformité Européenne) approved, no ozone emitted and 5 years warranty.

Airflow, speed, and CADR

Purifying coverage

1500 sq. ft. (139 m²)

Airflow speed

72 - 400 cfm (122 - 680 m³/h)

Fanspeed

Powered by the excellent all-round 360° progressive system with 72-400 cfm airflow delivery rate, Austin Air Allergy Machine has an impressive purifying applicable area up to 1500 sq. ft. that can cover almost any sizes of room including the living hall. Compare with other standard Austin Air purifiers, expect equivalent airflow performance and purifying coverage.

What’s inside count

Austin Air Allergy Machine 4-stage filtration is excellent for people suffering from asthma and allergies. The first stage filtration consists of outer mesh filter and inner pre-filter that would trap large particles such as pet hair. The 2-stage medium filter would, of course, capture medium size particles while the 3-stage HEPA filter would trap even smaller airborne particles. Finally, Allergy Machine High-Efficiency Gas Absorption (HEGA) filter would trap odor and gas-based allergens that often linked to household contaminants.

Without a doubt Austin Air Allergy Machine 4-stage filtration is highly efficient when take on common and micron size contaminants, allergens, viruses and bacteria. Made possible by ultra-powerful airflow distribution and wide purifying coverage, Austin Air Allergy Machine combined filtration is exceptional in eradicating hair, dust, pet dander, dust mites, fungi, pollen, mildew, mold, spores and germs. On handling odors and smokes, Austin Air Allergy Machine is also exceptional against cooking odors, radon, ammonia chemicals, VOCs, tobacco and cigarette smokes.

Keep it down

Noise level

40 - 65 dB

Power consumption

115 W

Austin Air Allergy Machine 40 - 65 dB noise is far from subtle and generally not suitable for night use. Without sleep mode or silent mode, the only way to prevent the air purifier from making too much noise is to place it as far as possible so long it's within its purifying range. On another note, 132 W power consumption is average for this segment air purifier.

At what cost

MRSP/ RSP**

+- 575

Annual Filter Cost

+- 50

^ Replacement filters/ estimated cost

Austin Air Allergy Machine is not cheap to begin with, the lack of any practical features is a further blow on the air purifier overall value. Filter replacement is another story as Austin Air Allergy Machine offer one of the lowest filter replacement cost in its class thanks to the extra-long filter lifespan. Not only you will save tons of money on the filter replacement, but you would also only have to deal with the hassle filter replacement every couple of years.

Austin Air Allergy Machine VS the challengers

Austin Air HealthMate HM400

At a much lower cost, the standard set offers decent enough filtration strength against most common allergens.

Austin Air Bedroom Machine

The ultimate version that comes with 5-stage filtration including 15 lbs. Activated Carbon and Zeolite and HEGA filter. It's also the most expensive unit in Austin Air lineup.
