Know before you buy
This pre-filter is specifically designed for the Austin Air Junior size units, including the HealthMate Junior, Allergy Machine Junior, and HealthMate Plus Junior models.
The pre-filter acts as the first line of defense by capturing large airborne particles like dust, hair, and pet dander. By trapping these larger contaminants, it prevents them from clogging the main HEPA filter, which helps maintain your purifier's overall efficiency and extends the life of the internal filter assembly.
No, this pre-filter is not washable. While you can gently vacuum the exterior of the unit to remove surface dust and prolong its performance, the filter itself should be replaced entirely every 12 months.
Austin Air recommends replacing the pre-filter annually. If you notice a significant buildup of dust or hair on the exterior of the unit that vacuuming no longer clears, it is a good indicator that the filter has reached the end of its functional lifespan.
No, the performance is identical regardless of the color. The black and white options are purely aesthetic, allowing you to choose the version that best matches the exterior finish of your specific Austin Air Junior unit.
