Honeywell Electronic Air Cleaner F300B 20x20

To assure optimum performance from the air cleaner, the cells and prefilters must be cleaned regularly and the postfilters replaced regularly—twice a year with normal use or more frequently with heavy use.

Washing frequency varies, depending on the number of family members, pets, activities (such as cooking or woodworking) and smoking habits.

NOTE: To let the heating or air conditioning system operate normally while the cells are being washed, simply turn off the air cleaner switch.

1. The quickest and easiest way to clean your prefilter is to use the brush attachment of your vacuum cleaner to vacuum the lint off the dirty side of the prefilter.

Greasy dirt may require soaking the prefilter in a tub or rinsing with the garden hose. Do not wash the prefilter in the dishwasher or car wash.

2. The prefilter should be cleaned every 6 months or more frequently with heavy use. This will keep the prefilter clean of air choking lint that can make your system work harder.

Cleaning your Cells • A quick cleaning of the cells can be done by simply wiping down the ionizer wires with a damp cloth. This will help boost the efficiency of the air cleaner between full cleaning cycles. This quick clean can be done every time the prefilters are cleaned.

• A full cleaning of the cells will return the air cleaner to its peak efficiency. An easy way to wash the cells is in a tub of hot, soapy water. Just soak the cells until the water cools, agitate and rinse.

Warning: This cleaning procedure requires trained personnel with PPE!

Pressure drop across the air cleaner

Pressure drop is less than 0.5 in. w.c. (0.1 kPa)?

If pressure drop is more than 0.5 in. w.c. (0.1 kPa), clean the air cleaner immediately.

Is the air cleaner installed downstream from an atomizing humidifier or does the installation include both heating and cooling?

If yes, more frequent replacement may be necessary.

If yes, clean the prefilters promptly to avoid restricting airflow and reducing efficiency of the heating-cooling system.

Warning: Ensure to follow the correct procedure for replacing the media postfilters

Old filter removed successfully?

New filter available for replacement?

If new filter is not available, contact your local Honeywell distributor to purchase replacement filters

New filter installed correctly?

Always disconnect power and open access door before opening power supply cover.

The electronic air cleaner generates a small amount of ozone in normal operation.

During the first week or two of operation, the amount may be higher because of sharp edges on some of the new high voltage metal parts.

Normal use quickly dulls these edges.

If desired, the ozone generated by the air cleaner can be reduced in one of two ways:

1. Install an activated carbon filter downstream from the air cleaner. Make sure particles from the air filter cannot fall into the air cleaner.
