Premium powder-coated steel housing that stands out from most plasticky air purifier, Austin Air Allergy Machine Jr 11 x 16.5 x 11 in dimension is no different from other Austin Air Junior air purifier. On the other hand, 24 lb weight is lighter in its Jr group due to the different set of filter although it’s still far from light compare with other competitors model. Moving around the air purifier has to be done without the casters support as casters is an additional purchase. Austin Air Allergy Machine Jr is dead easy to use as there is only one front rotary dial knob up-front to control the fan speed. Other notable spec includes 60° progressive Intake System, 4-stage filtration, long-life all-in-one filter, NRTL (Nationally Recognized Testing Laboratory) recognized, CSA (Canadian Standards Association) and CE (Conformité Européenne) approved, ozone-free emission, 30 days money-back guarantee and 5 years warranty on residential use. Fancy features such as auto mode, sleep mode, air quality status, digital indicator, and timer are all excluded.

Filters And Performance

Austin Air Allergy Machine Jr 4-stage filtration is no doubt great against airborne particles, chemical vapors, odors, and allergens. First off the combined effort between outer mesh grille and inner pre-filter would trap large particles while the medium particulate filter would follow up the job on medium-sized particles; unique HEGA filter that traps any vapors, gases, and odors related chemicals. Finishing up with the filtration is Austin Air Allergy Machine Jr HEPA filter that would deal with micron-size particles e.g. bacteria that were not captured by the previous filter.

As mentioned in the previous Junior series, Austin Air Allergy Machine Jr is a relatively noisy air purifier at 40 - 65 dB particularly at third speed. Placing the air purifier further back from the bed would help mitigate the noise which is possible thanks to the wide purifying coverage. Power consumption is market standard at an average of 80 W and there is no sleep mode/ night mode to further improve on the figures.

^ Replacement filters/ estimated cost
While Austin Air Allergy Machine Jr is far from cheap given the lack of modern features, the filter is and should be the main reason to go for this air purifier. As most air purifiers would last you for at least a couple of years, the estimated 5 years filter lifespan would greatly bring down the filter replacement cost and annual mandatory effort in replacing the filter. One little downside to Austin Air Allergy Machine Jr is replacing the filter is not as straightforward as a most air purifier with front pop-out cover. You would need to unscrew and pop out the cover, remove the exhausted filter and replace it with the new filter before closing it up.
