Austin Air F400A Features

Standard Pre-Filter

Keep your Austin Air purifier running like new with a genuine standard large particle prefilter replacement, available in black or white to match your unit. This essential first-stage filter captures visible airborne particles like dust, hair, pet dander, and other debris — preventing them from clogging your main filter and compromising performance.


Swapping out your prefilter regularly not only boosts airflow and energy efficiency, but also extends the life of your main filter, saving you money in the long run.


  • White filter is designed for White and Sandstone units
  • Black filter is designed for Black and Midnight Blue units


What does this prefilter actually do?

The prefilter captures visible airborne debris like dust, pet hair, lint, and dander before it reaches your main filter. This protects your unit and helps it run more efficiently.
