Austin Air Allergy Machine weight
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.

^ Austin Air Allergy Machine filters/ technologies/ lifespan
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.

Keep it down

Power consumption

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.

^ 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.

More on Austin Air HM405

Smooth in design with a focus on comprehensive filtration, Austin Air HM405 is similar to every other Austin Air air purifier with a standard dimension and weight. Built on powder lined finish steel exterior, the body consists of a 360° progressive filtering intake system supported by the non-fancy 3 dial fan speeds knob. Inside of Austin Air Allergy Machine is the powerful 4-stage filtration system that consists of 2 back to back pre-filters, medical-grade HEPA filter, and all new High-Efficiency Gas Absorption (HEGA) filter. The HEGA filter is an activated carbon cloth that is placed at the last stage of the 4-stage filtration and it has the same filtration quality used in military or hospital. It is extremely effective in handling chemicals, gases, and odors and the carbon cloth does not create any dust thus prevent the filter from being cluttered up with existing particles.

Applicable area, airflow, noise level and power consumption

As with most Austin Air air purifier, Austin Air HM405 has an applicable area of 87 m2 (938 sq. ft.) with 2 airflow charges released hourly. Placing the HEGA after HEPA filter enables Austin Air Allergy Machine to remove the most irritant allergens and odors (typically cigarette smoke) that could trigger serious respiratory allergies. At a consistent airflow delivery rate, you can expect a swift purifying speed within the air purifier surrounding. Noise level is at 39.8 dB minimum to 64.5 dB maximum; not great but acceptable, the power consumption level is standard at 115 watts.

Final thoughts on Austin Air HM405

Compare with HealthMate series, Austin Air HM405 is more efficient in gases, chemicals, and odors control all because of the inclusion High-Efficiency Gas Absorption (HEGA) activated military carbon cloth filter. The additional filter is extremely handy as an allergy or asthma relief typically for people that are sensitive to allergens. We would also recommend Austin Air Allergy Machine to people that are constantly surrounded by smokers so you can breathe more freely.
