Application Considerations

The Resideo F300 Electronic Air Cleaner is designed to work with gas, oil, and electric forced warm air
furnaces and with compressor cooling. It can also be used with heat pumps if the filter is changed regularly to
prevent excessive pressure drop. The F300 Electronic Air Cleaner is not recommended for applications where
pressure drop may be critical.

Models

F300E: Includes cabinet, access door, solid state power supply, two electronic cells, two metal mesh prefilters,
and two media postfilters.
F300A, B: Includes cabinet, access door, solid state power supply, two electronic cells and two metal mesh
prefilters.

Air Conditioning

Mount the Electronic Air Cleaner upstream of the evaporator coil in a cooling system. The filter will help to
keep the coil clean and reduce maintenance.

Humidifiers

An evaporative humidifier can be mounted upstream from the air cleaner. An atomizing humidifier should be
mounted downstream from the air cleaner, even though hard water salts will be blown into the living space
and deposited as dust. If an atomizing humidifier must be mounted upstream from the air cleaner:
1. Mount it as far as possible upstream from the air cleaner.
2. Install a standard disposable furnace filter between the humidifier and the air cleaner to trap water
droplets and hard water salts.
3. Frequently clean the air cleaner to prevent a hard water salt buildup.
NOTE: The volume of water that is discharged from an atomizing humidifier can overload the air cleaner,
resulting in hard water salts being deposited as dust in the living space.
