CLEANING AND MAINTENANCE
• Use a clean, dry cloth to wipe the external surfaces of the air purifier. DO NOT USE WATER, GASOLINE,
POLISH, OR ANY CHEMICAL SOLUTION.
• The ifD filter and pre-filter should be cleaned at least once every three months, or sooner depending
™
on the air quality of the room (See "Removing/Cleaning the ifD
respectively).
NOTE: If you smoke, burn candles or oil lamps in your home, it is recommended that you wash your filter
more frequently. When burned in an enclosed space, candles and oil lamps have a tendency to introduce
soot into the air.

My filter bar says my filter is still relatively clean but when I checked my filter it was really dirty.
(HHT-215, HHT-217 or HHT-219 Only)
In conditions where smoke, pets or air with a lot of contaminants are present it is possible that the filter
could be dirty sooner than indicated on the filter clean monitor bar. The filter clean monitor on your
unit runs on a timer and if there are more particles in your air than in an average home, your filter could
capture airborne particles sooner than indicated on the display. The monitor is intended to be used as a
guideline and individual environmental conditions will vary.
Is my Air Purifier considered an ozone generator?
No. Ozone generators produce large amounts of ozone as the primary way to clean the air. The EPA
does not endorse these products because they can cause ozone related health problems. The air
purifier does not use ozone as the primary method to clean the air. It cleans the air by using ifD
technology (Intense Field Dielectric) which only generates trace amounts of ozone, substantially below
the limits established by the EPA and FDA.
