Description
The Austin Air Replacement Pre-Filter (F400) replaces the pre-filter that comes with Austin Air standard-size air purifiers. This pre-filter traps particles over ~10 microns that can easily be seen with the eye during the first stage of Austin Air's multi-stage filtration process. The pre-filter thus helps to prolong the life of the inner filters, especially the HEPA filter. The F400 pre-Filter lasts for years under normal operating conditions and with regular care. 

Because it can be seen through the air cleaner's grille, choose the Black F400 pre-filter for Black-Silver-Blue units or the White F400 pre-filter for Sandstone-White units. 

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.
