Compatibility: This prefilter is compatible with Honeywell F50 and F300 series electronic air cleaners. It can also be used with metal risers.

3. Installation

1. Power Off: Before attempting any installation or maintenance, ensure your electronic air cleaner unit is powered off and disconnected from its power source to prevent electrical hazards.
2. Locate Prefilter Guides: Open the access panel of your air cleaner and locate the upstream prefilter guides. These are typically slots or channels designed to hold the prefilter in place.
3. Insert Prefilter: Carefully slide the Honeywell Washable Prefilter (Model 203372) into the designated upstream prefilter guides. Ensure it is seated securely and correctly.
4. Close Access Panel: Close and secure the air cleaner's access panel.
5. Restore Power: Reconnect the power source and turn on your electronic air cleaner.

Important: Always ensure the prefilter is completely dry before installation. Installing a wet prefilter can lead to operational issues or damage.

4. Operation

Once installed, the washable prefilter operates continuously as part of your electronic air cleaner system. It works by trapping larger particles such as dust, lint, and pet dander, preventing them from clogging the finer filtration stages. Regular cleaning of the prefilter is crucial for maintaining the efficiency and performance of your air cleaner.

5. Maintenance and Cleaning

Regular cleaning of your washable prefilter is essential for optimal air cleaner performance. The frequency of cleaning depends on usage and environmental conditions, but it is generally recommended to inspect and clean the prefilter every 1-3 months.

Cleaning Procedure:

1. Power Off and Remove: Turn off and unplug the air cleaner. Carefully remove the prefilter from its guides.
2. Initial Cleaning Options:
   • Vacuuming: Use a vacuum cleaner with a brush attachment to remove loose dust and debris from both sides of the prefilter.
   • Brushing: Use a soft brush to gently dislodge accumulated particles.
3. Washing (Optional, for deeper cleaning):
   • Soaking: For stubborn dirt, soak the prefilter in a tub of warm, soapy water. Use a mild detergent if necessary.
   • Rinsing: Rinse thoroughly with clean water until all soap residue is removed.
4. Drying: After cleaning, allow the prefilter to air dry completely. This is critical. Do not reinstall a wet prefilter. Ensure all moisture has evaporated before placing it back into the air cleaner.
5. Reinstallation: Once completely dry, slide the prefilter back into the upstream prefilter guides as described in the Installation section.

DO NOT wash the prefilter in a dishwasher or car wash, as this can damage the filter material or frame.

6. Troubleshooting

If your electronic air cleaner's performance seems diminished, consider the following:

• Reduced Airflow: A clogged prefilter can restrict airflow. Perform the cleaning procedure outlined in Section 5.
• Ineffective Filtration: Ensure the prefilter is correctly installed and fully dry. A misaligned or wet prefilter may not function optimally.
• Unusual Noises: Check that the prefilter is securely seated in its guides. A loose prefilter might vibrate.

For issues beyond prefilter maintenance, refer to the main instruction manual for your Honeywell F50 or F300 series electronic air cleaner.
