Operation

INSTALL PRE-FILTER BEFORE INITIAL OPERATION.

Refer to “Removing/Changing the Filters” section for proper installation.

To encourage operation on higher speeds, the Honeywell

18155 air purifier has been designed to operate very quietly and effectively without a cool exhaust draft. To operate, press the POWER button to HIGH speed for a few seconds, and then leave it on high for faster, more powerful air circulation, or move it to a lower setting as desired.

Intelli-Check™Filter Indicators

The Intelli-Check™Filter Indicators serve as a convenient guideline for when to clean the LifeTime HEPA™ Permanent Filter and when to replace the carbon pre-filter. Depending upon your individual usage (environment and hours used), you may need to clean/replace the filters more or less frequently.

When the HEPA Filter Indicator Light turns on, it’s time to clean your HEPA filter. The Intelli-Check™reminder for when to clean the HEPA filter is intended as a guideline only as the performance of the filter media is dependent on the concentration of the contaminants to which the system is exposed. If there are sources of large amounts of contaminant generation (such as dust from woodworking or heavy smoking) the HEPA filter in your air purifier may need to be cleaned more often. For instructions on how to clean your HEPA filter, refer to section “Cleaning the LifeTime HEPA™ Permanent Filter” in this manual.

When your Pre-filter Indicator Light turns on, it’s time to replace your pre-filter. It should be replaced at least every 3 months. If there are heavy concentrations of odors, smoke, or large particles in the home, you may need to change the carbon pre-filter more often. For instructions on how to replace your pre-filter, refer to section “Removing/Changing the Filters” in this manual.

Note: We do not recommend operating the air purifier without the carbon pre-filter.
