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.

Science has proven water has the potential to transform your world view. Crystals formed in frozen water reveal changes when specific, concentrated thoughts are directed toward them. Water that has been exposed to loving words shows brilliant, complex, and colorful snowflake patterns. The implications of this research create a new awareness of how we can positively impact the earth and our personal health.- Dr. Masaru Emoto The Hidden Messages in Water.
