Common questions about manuals, registration, and support for this brand.
On models like the mod+ and AirMend, press and hold the filter reset icon or button for approximately 4 seconds until the red light turns off.
The serial number is typically printed on the rating label located on the back, bottom, or near the power cord entry of the machine.
Filters should generally be replaced every 6 to 12 months depending on usage and air quality. The unit will display a red indicator light when it is time to check or replace the filter.
The mesh pre-filter (available on some models) can be vacuumed or rinsed, but the main HEPA and carbon filters are not washable and must be replaced.
Ensure the improved safety features are engaged: check that the front or rear cover is securely snapped into place and that the filter is properly seated, as the unit will not power on if these are loose.
