If you have a humidifier
All Honeywell whole house humidifiers can be used in a system with the Honeywell
Electronic Air Cleaner without any additional filters or system modification.
If your system includes an atomizing humidifier, you may want to install a standard
furnace filter between the humidifier and the air cleaner.This filter would keep the
humidifier spray mineral deposits from collecting on the air cleaner.This filter should be
checked regularly and changed when it shows signs of mineral or dirt buildup. If you do
not install a filter, you will probably need to wash the cell(s) and prefilter(s) more often
to remove the mineral buildup.
If an ultrasonic room humidifier is used often, especially if filled with tap (undistilled)
water, the cell(s) and prefilter(s) require more frequent washing. A white residue
accumulates on the cell(s) from the minerals in the water. This residue may also
contribute to "white dust.” See About lint or “white dust” section for more information.
