To encourage operation on higher speeds, the Honeywell 18150 series air cleaner 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 Monitors…
This air cleaner is equipped with Intelli-Check Filter Monitors to serve as a convenient guideline for replacement of the pre-filter and HEPA filter based on the air cleaner’s hours of use and operating speed. This is beneficial because a filter’s life depends on the amount of air and contaminants drawn through it. The monitors have the ability to indicate the amount of expected filter life used. Once a filter has reached the end of its expected life, its light will remain on until it is RESET. You may unplug the air cleaner without interrupting the filter monitors.
The Intelli-Check™ Filter Monitors count the expected filter life based on an assumed average operating time of 12 hours a day on medium speed. Therefore, it will indicate replacement of the Pre-filter in about 3 months, and the HEPA filter in about 1 year and 9 months. Depending upon your individual usage (environment, hours and speed of operation), you may need to check and replace the filters more or less frequently.
To CHECK Expected Filter Life Usage When the unit is turned on, quickly press the filter monitor button. The pre-filter light will flash up to 3 times and the HEPA filter light will flash up to 4 times, depending upon how much expected filter life has been used.
Remains on =
from new, up to 1/3 expected life used up between 1/3 and 2/3 expected life used up between 2/3 and all of expected life used up time to replace pre-filter
Remains on =
from new, up to 1/4 expected life used up between 1/4 and 1/2 expected life used up between 1/2 and 3/4 expected life used up between 3/4 and all of expected life used up time to replace HEPA filter
To RESET Filter Monitor When the filter monitor light remains on, it is time to replace the filter and reset the filter monitor. With the unit powered on, press and hold the filter monitor button down for approximately 5 seconds until the light turns off.
