Replacement Pre-Filter for Austin Air's standard-size air purifiers, like the HealthMate (HM400), the
HealthMate Plus (HM450), the
Pet Machine (HM410), the
Allergy Machine (HM405), and the
Bedroom Machine (HM402) by Austin Air. Also called the
Permafilt Pre-Filter. This Pre-filter traps large and medium-sized particles in the first two stages of Austin Air's 4-stage filtration process:
- The pre-filter's first layer traps large particles, such as dust and hair
- The pre-filter's second layer captures molds, pollens and other medium-sized particles before air passes to the purifier's HEPA Filter
The Pre-Filter can last for years because it can be washed or vacuumed when dirty. It can be seen through the grill in the air purifier. Therefore, pre-filter replacement should correlate with the color of your Austin Air purifier. Select the White pre-filter for White or Sandstone models, and the Black pre-filter for Black, Blue or Silver models.
Package contains one (1) Permafilt Pre-Filter.

Wash or vacuum the pre-filter when dirty. Help keep the pre-filter clean by simply vacuuming the outside grill of the air purifier to reduce surface buildup and prolong the life of the pre-filter.
The pre-filter can last for years with regular cleaning, although replacing your pre-filter annually is an option for the cleanest air. Either way, this pre-filter avoids regular filter changes often required with other air purifiers, for cost savings and long-term value.
