Air Purification Cartridge Filter Particles or Rattling Sound

Topics:

  • Is the air purification cartridge damaged if it is covered in a fine white powder when shipped?
  • Should the air purification filter come coated with white particles on the outside of it?
  • Is air filter broken if it makes a rattling noise when shaken?

Answer:

Air purification cartridges may make a rattling sound, which is normal. Cartridges contain small glass tubes that are part of the air filtration system.

  • If there is a problem with the air filter, the filter icon will flash on the control panel.
  • If there is no issue with the air purification cartridge, the filter icon will be steady.
  • White powder produced during the manufacturing process may be present. It is not harmful. If present, wipe the cartridge with a dry cloth prior to installation.
