Genuine Austin Air Permafilt Pre-Filter (F200) replaces the pre-filter that comes with Austin Air junior-size air purifiers. Long-life pre-filter traps large-sized particles 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 or for Baby's Breath Pink-Blue units.
