7. Press TIMER to have the air purifier run for a set amount of hours (either 4, 8,, or 12) before turning off.

How to Replace the Filter

2. Distinguish the front side from the back side of the filter. The front side has a foam-like Pre-Filter attached with Velcro®.
3. Place the used filter in a plastic bag to prevent dust from re-entering the air.

How To Clean The SmartSensor

The SmartSensor uses an infrared light to detect airborne particles. After prolonged periods of use, dust can accumulate on the glass lens and affect the sensitivity of the sensor. If this occurs, your unit will run on the highest speeds when set in Automatic mode and will not come down to the lower speeds even after cleaning the air. To clean the sensor lens, first turn your unit off. Wet the end of a cotton swab with water and wipe the lens with it. Dry the lens with the other end of the cotton swab. For best performance, clean the SmartSensor lens each time you replace your filter.

TROUBLESHOOTING TIPS

• How do I reset the filter indicator lights?  I put in a new filter, but the red or yellow lights are still illuminated.
  After changing the filter, RESET the filter indicator by holding down the FILTER LIFE button for 5 seconds while the unit is ON. The light above the FILTER LIFE button should reset to green.
• My BreatheSmart always runs at the highest speeds when in Automatic Mode.
  The BreatheSmart unit may not come down from the highest speeds when in Automatic Mode for two reasons: Your air is dirty and still needs to be cleaned, or the SmartSensor lens has dust on it and must be cleaned.  See “How To Clean The SmartSensor” on page 9. 
• How do I find out what electrical specifications my unit needs?
  Please refer to the rating label on the back of the unit.  Here you will find your unit’s voltage, hertz, amps, and outlet requirements.
• Can I clean the filter?
  The black foam layer of the filter, known as the Pre-Filter, captures large dust and hair.  This layer is held on with Velcro®.  Once removed, the Pre-Filter can be washed or vacuumed to maintain efficient operation of the unit.  No other layers or parts of the filter can be washed, cleaned, or otherwise reused.  Please replace the filter regularly to maintain optimal performance.
