Genuine Austin Air Permafilt Replacement Pre-Filter (F400) replaces the pre-filter that comes with Austin Air standard-size air purifiers. Long-life pre-filter captures large-sized particles, like dust, hair, soot and pet dander that can easily be seen with the eye during the first stage of Austin Air's multi-stage filtration process. In performing this role, the pre-filter helps to prolong the life of the inner filters, especially the HEPA filter. Pre-Filter lasts for years under normal operating conditions and with regular care.  Package contains one (1) Permafilt Pre-Filter.

Because it can be seen through the air cleaner's grille, choose the Black pre-filter for Black-Silver-Blue units or the White pre-filter for Sandstone-White units.

Austin Air Filter replacements are subject to Minimum Advertised Pricing (MAP).

Features:

  • Austin Air Permafilt Pre-Filter (F400) captures large particles, like dust, hair, soot and pet dander
  • Protects life of HEPA and other inner filters
  • Lasts for years with proper care, under normal conditions
  • Designed to be vacuumed from outside of unit to avoid costly 3-month filter changes
  • Fits all standard-size Austin Air purifiers:
    • Allergy Machine (HM405)
    • Bedroom Machine (HM402)
    • HealthMate (HM400)
    • HealthMate Plus (HM450)
    • Pet Machine (HM410)

Care Instructions:

  • Clean the pre-filter when dirty, simply by vacuuming the outside grille of the air purifier with the brush attachment of your vacuum on a monthly basis to reduce surface buildup and prolong the life of the pre-filter.

  • The pre-filter can last for years with regular cleaning, although replacing 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.

Changing the Pre-Filter:

  • Please see Owner's Manual tab for full instructions on filter changes, including a one‐page quick reference sheet.
