Austin Air Replacement PreFilter
PERMAFILT Pre-Filter replacement for Austin Air Purifiers.
The pre-filter traps large dust particles from entering the inner filter. They are designed to be vacuumed from outside and eliminate costly 3-month filter changes typical of other air filters. We recommend vacuuming the Pre-Filter once a month.
White Pre-Filters are for the following coloured units: Sandstone, White, Baby’s Breath Pink and Baby’s Breath Blue.
Black Pre-Filters are for the following coloured units: Midnight Blue and Black.
