The F500B1009 HEPA Air Cleaner model has been discontinued.
The recommended replacement is an F500A1000.
Unlike the F500B1009, the F500A1000 has no insulation in the cabinet and therefore is used in conditioned spaces only. The F500A can be used in unconditioned space as long as external insulation is used around the product. We do not sell external insulation for the F500A.
