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.
Austin Air Filter replacements are subject to Minimum Advertised Pricing (MAP).
Changing the Pre-Filter:
I've had my Austin Air for years. It's a quiet running air cleaner compared to other HEPA cleaners, and it's easy to maintain. High quality. If it broke, I would go buy another one. I've had mine for over 10 years now, I think, and still running fine. (Posted on 7/18/10)
The Austin Air Filter is the best room air cleaner I've ever found. Maintenance is so easy. The pre-filter needs to be changed every 6 months, and then I vacuum the main filter. I have 4 of these around the house (I have severe allergies) and 2 of them have already gone over their 5 year estimated lifetime. All other air filters make you change the pre-filter every 3 months and the main filters yearly - they are too expensive and it's too dirty a job, plus they don't work near as well as the Austin Air Filter.
