Yes. Evaporative type humidifiers release water as pure vapor. Water vapor will not create any problems with an electronic air cleaner. Misting or spray type units mounted on the return air plenum could cause problems with an electronic air cleaner.
The model number of the flow-through humidifier is located at the bottom of the unit, near the water supply valve on a white sticker and begins with HE. The model number for TrueSTEAM Humidifiers is located on a sticker on the left side of the top of the unit and begins with HM.

Honeywell recommends replacing pads once every season.
Optimal Relative Humidity (RH) is defined by industry experts* as between 40-60% RH on an average annual basis, and 35% during the heating season in dry climates. An environment with too little humidity leaves the body vulnerable to viruses and bacteria, and can cause woodwork in the house to shrink and crack. On the other hand, too much humidity creates ideal conditions for mold and mildew growth. The recommended settings are based upon the outdoor temperature: -20F (-30C) or below 15% -10F (-24C) 20% 0F (-18C) 25% 10F (-12C) 30% 20F (-7C) 35% Higher temp 40% As with any recommended settings, these are general recommendations. Other factors in the application can affect the humidity level achieved in your home. If you notice condensation on your windows, please lower the setting on the humidistat.
Honeywell recommends a minimum distance of 3 feet between a UV light and plastic fabricated devices (such as humidifiers and non-fiberglass media filters)
The humidifier can be used on a hard water supply however; the pad may need to be replaced more frequently because of possible buildup of minerals diminishing its ability to operate normally. If there is access to a water softener, then it is recommended that the water coming to the humidifier passes through the softener first.
Please verify the model number of the humidifier pad. If the model number is HC26P, then these humidifier pads do not need to be orientated in a particular direction for proper operation. The model number for these pads would be available on the carton.
There are a variety of factors that can affect the level of humidification that can be achieved. The first consideration must be to proper sizing of the humidifier. Please verify that the Humidifier either the HE360 or the HE365 fits your home’s size and how tightly constructed your home is using the following guide. House construction maximum area the (HE360 / HE365) can adequately humidify: Loose - 1900 Square Feet Average - 2700 Square Feet Tight - 4200 Square Feet Please also verify that there are no mineral deposits on the humidifier pad. Accumulations of mineral deposits on the humidifier pad can affect the ability of the pad to hold water. Change the humidifier pad if necessary. Please be aware that colder outdoor temperatures limit the amount of humidity that can be added to your home without resulting in condensation on the windows. The more the heat runs the more that this will dry out the air passing through a furnace or a heat pump application. If after considering the above factors, you still feel that you are not achieving adequate humidity levels in your home, please consult your local heating and cooling contractor.
