Austin Air HealthMate HM400 Replacement Filter

Do you have an AustinAir HealthMate or HealthMate Plus? This is the replacement filter that retails for $650+. It's unused. I don't have to replace mine for another few years so don't need this one. The Austin Air HealthMate HM400 Filter is constructed using a true medical High Efficiency Particulate Arresting (HEPA) filter (rated MERV-17) surrounded by a carbon/zeolite mixture capable of removing the tiniest of particles and absorbing odors and gases. The Austin Air HealthMate HM400 Filter uses the HEPA to remove up to 99.97 percent of all particles down to 0.3 microns in size and 95 percent down to 0.1 micron. All replacement filter cartridges will also come with a replacement pre-filter.
