For Best Performance We recommend that you operate your Honeywell air purifier 24 hours a day because indoor air can be quickly contaminated by activity in a room, infiltration of outside air, and from other sources of contamination. While all the air in a room will not be processed by the air purifier, the more air circulated through the filter, the more filtered air is returned to the room.
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.
