Troubleshooting for your Filterqueen Defender
Defender is loud and noisy:
This means your filters are colgged and need to be replaced.

To replace old filters:

  • Unplug the Defender from the wall.
  • Brig it outside and harmful contaminants are held in these filters.
  • Turn the Defender over.d
  • Unscrew the bottom nut that holds the machine together.
  • Take off the base of the Defender (sometimes the filters and the casing will stick, that's ok. That means you have proper airflow though the machine).
  • Remove the outside casing from the filters (this should just slide off).
  • Then remove the black charcoal filter (it is wrapped around the white medical filter and is held together by velcro).
  • This filter should be dirty and look almost white on the outside, meaning it is clogged and needs to be replaced with a new black charcoal filter).
  • Check the white medical filter (should be changed once [1] every year). If it is darker on the outside than the inside it should be replaced as well.
  • Replace the charcoal filter with a new one (should be replaced every 6 months).
  • Wrap it around the white medical filter and secure it tightly by the velcro strips.
  • Put it unit back together just has you took it apart.
  • Screw it all together by the nut on the bottom. Simply screw it back on until the nut stops.
  • Plug it back into the wall, turn it on and it will run like brand new.
