How can I identify and replace my filters?
To change your air cleaner or humidifier filter, you must first switch
your thermostat to the off position. If you have an electronic air
cleaner, it must be switched off too; there will be a second power
off switch on the air cleaner itself. To replace the humidifier
water panel, it is necessary to first identify the humidistat. The
humidistat controls the flow of water through the humidifier panel.
The humidistat is a small control attached to the return air duct;
some are positioned next to the heating/cooling thermostat. The humidistat
can be identified by a dial that should read either 10-20-30-40% or
hi-med-low on the front of the control. If are having trouble locating
the humidistat, find a thin wire attached to the humidifier and follow
it to the humidistat located at the other end!
Locate your furnace to identify the cold air return; it will be the
large duct that attaches to the side of the furnace, generally towards
the bottom. Where the return duct attaches to the furnace, you will
find a vertical slot that will vary in size and thickness ... that
ís your air cleaner! Follow the return duct a few feet and you will
see the humidifier! Please note that the humidifier can be mounted
on all sides of the return duct.
Makes & Models
The manufacturerís make and model should be clearly visible on the outer
door or casing of the humidifier or air cleaner. Many humidifiers have
the make on the front and the model on the side of the outer casing.
Electronic
Air Cleaners
The make is generally found on the front door. The model and serial number can
be found on the back of the front door.
Humidifier Water Panel Replacement (Non drum type)
The water panel inside your humidifier is a honeycomb-patterned cartridge
and there are generally two ways to access it:
Aprilaire Models: Remove the door and the filter should be
clearly visible in front of you.
Carrier, General, Honeywell Models: Identify the bottom of
the humidifier where the drain line attaches to the humidifier, and you
will notice that there are one or two screws, one on either side of the
drain spout. Loosen the screws and you should be able to unhinge the bottom
assembly. Carefully remove the bottom and the filter will fall out at the
same time. Occasionally it is necessary to disconnect the clamp connected
to the drain. Finally, refer to the back of our genuine replacement
water panel box and follow the easy ìHow to change your filterî steps.
For assistance with all other humidifier models, please refer to your
owner's manual or contact our Customer Care Department.
Air Cleaner Media Filter Replacement (Non-electronic)
Once you remove the door, the disposable filter should be clearly visible.
The replacement part number and the size of the filter are usually printed
on the outer edge of the filter. If your filter is labelled 20x25x5, you
require a filter 20" x 25" in size and 5" in thickness. The actual size of
the filter is slightly less. When replacing the filter pay particular
attention to the ìair flowî arrows printed on the filter. As a general
rule, the arrows point towards the furnace.
