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.
