Austin Air FR400 HealthMate Air Purifier (HM400) Filter Replacement

The filter is fine, but required some aggressive work with a hammer to make it fit my antique model. Compared to the previous replacement filter, this one had metal where the old one had fiberboard. I suppose this would be an upgrade, except that the designer apparently didn''t consider the placement of some bolts on my 15 year old Healthmate; hence the need to put some serious dents into the filter. The previous replacement filter had the same problem, but the fiberboard had more give to it. It is my unscientific impression that the new filter is not as quiet out of the box as the previous replacement filter was (based on my 5 year old memory), but maybe it''s just my machine getting older; or different room acoustics. Perhaps another owner can offer a second opinion.

How can you tell if your Austin Air System needs a new filter? If even the lowest fan speed can be heard around the house, it''s time to replace the filter. After putting this filter in my Austin, it is so much quieter. I guess that means these filters do their job and cleans that nasty stuff out of the air.
