• Midnight Blue machines use Black pre-filters.
• The FR460 is a special order filter that is not returnable. It is a HEPA and Zeolite filter without any Carbon.

There are two indications that your filter needs to be replaced:

• An unpleasant odor coming from the unit means that the carbon in the filter is full, and the filter needs to be replaced, and
• Significantly reduced airflow coming from the unit means that the HEPA filter is full, and the filter needs to be replaced.
