How to Install a Filter in a Honeywell Air Purifier?

Published in Air Purifier Maintenance 3 mins read

Unfortunately, the provided references only describe changing a filter in a Honeywell air purifier, not specifically installing one, which usually implies the very first setup. However, the process is very similar. Here's a general guide based on the available information and common air purifier designs:

Since the provided information mentions upright position, the instructions below will assume a tower-style Honeywell air purifier. However, the general principles apply to other models; consult your specific model's user manual for precise instructions.

  1. Unplug the Air Purifier: Before you begin, ensure the air purifier is unplugged from the electrical outlet for safety.

  2. Open the Filter Compartment:

    • Typically, the filter compartment is located at the back of the unit.
    • There is usually a panel or grill that needs to be removed. This panel might have clips, latches, or screws holding it in place. Refer to your user manual for the exact opening mechanism.
  3. Remove Existing Filters (if applicable): If this is a brand new unit, there shouldn't be any. However, if you're simply changing the filter, carefully remove the old filters (usually a pre-filter and a HEPA filter). Note their orientation for easy replacement.

  4. Install the New Filters:

    • Pre-Filter: The pre-filter is designed to capture larger particles like dust and pet hair. It's usually a thin, washable filter. Place it in the compartment according to the model-specific instructions (usually against the grill).

    • HEPA Filter: The HEPA filter captures finer particles like allergens, pollen, and smoke. Place the HEPA filter behind the pre-filter (further inside the unit). Make sure it fits snugly. HEPA filters often have an "air flow" direction; ensure it's facing the correct way (usually indicated by an arrow on the filter frame - point the arrow in the direction of the air being pulled into the machine).

  5. Close the Filter Compartment: Replace the panel or grill you removed in step 2. Make sure it is securely fastened.

  6. Plug in the Air Purifier: Plug the air purifier back into the wall outlet.

  7. Power On and Reset Filter Indicator (if applicable): Turn on the air purifier. Some models have a filter replacement indicator light. If yours does, you'll likely need to reset it after installing the new filter. Refer to your user manual for instructions on how to reset the filter indicator light.

Important Considerations:

  • Refer to your specific Honeywell air purifier model's user manual for detailed instructions and diagrams. Filter installation can vary slightly between different models.
  • Filter Types: Honeywell air purifiers often use a combination of filters: a pre-filter for larger particles and a HEPA filter for finer particles. Some may also have activated carbon filters for odor removal. Ensure you install the correct type of filter in the correct location.
