Troubleshooting Guide
The following section provides the solutions to many common problems and
questions. If your air purifier is not working correctly, review these solutions
first. If your problem is still not solved after reviewing this guide, call our toll-free
customer service number, listed on the front cover of this manual, for assistance.
Reduced Air Flow or Poor Filtering
• The intake or outlet grille may be
blocked. Make sure nothing is in
front of or directly behind the air
purifier.
• The HEPA filter may be clogged.
Replace if necessary.
The Air Purifier Will Not Turn On
• Is the air purifier plugged into a
powered outlet?
• Is the fan speed knob turned on?
The Air Purifier Changes Speed
• Air Quality Sensor models are
designed to sense the level of conta-
minants in the air and adjust the fan
speed to provide the most effective
air purification possible. If the Air
Quality Sensor control is set to Auto,
it will automatically change fan
speeds to adjust for changing air
quality.
