This comprehensive guide will walk you through everything you need to know about cleaning your Honeywell tower air purifier filter, covering different filter types, step-by-step cleaning instructions, preventative maintenance, and when it’s time to replace the filter altogether. By the end of this article, you’ll be equipped to keep your air purifier running optimally and breathing easier.

Understanding Your Honeywell Air Purifier Filter

Honeywell tower air purifiers use different types of filters, each requiring slightly different cleaning or replacement procedures. Knowing your filter type is crucial for effective maintenance.

Common Honeywell Filter Types

• Pre-Filter: Typically a washable foam or mesh filter designed to capture large particles like dust, pet hair, and pollen. These extend the life of other filters.
• Activated Carbon Filter: Often combined with a pre-filter, these filters absorb odors, gases, and volatile organic compounds (VOCs). These are not washable and must be replaced.
• True HEPA Filter: The core of most Honeywell purifiers, HEPA filters capture 99.97% of airborne particles as small as 0.3 microns, including dust mites, mold spores, and bacteria. These are generally not washable, but some models have washable pre-filters attached.
• Permanent Washable Filter: Some newer Honeywell models utilize a permanent washable filter which combines the functions of a pre-filter and HEPA filter.

How to Clean Your Honeywell Tower Air Purifier Filter

The cleaning process depends on the type of filter you have. Here’s a breakdown for each:

Method 1: Cleaning a Washable Pre-Filter (Most Common)

This method applies to the foam or mesh pre-filter found on many Honeywell models.

Diagnosing the Issue

A visible buildup of dust and debris on the pre-filter indicates it needs cleaning. Reduced airflow is another sign.

Fix Steps

1. Power Off & Unplug: Always disconnect the air purifier from the power outlet before beginning any maintenance.
2. Access the Filter: Locate the filter compartment (usually on the back or side of the unit). Refer to your owner’s manual for specific instructions.
3. Remove the Filter: Carefully remove the pre-filter.
4. Vacuum (Optional): Gently vacuum the filter with a brush attachment to remove loose debris.
5. Wash the Filter: Rinse the filter under lukewarm running water. Do not use soap or detergents. Gently rub to remove dirt.
6. Rinse Thoroughly: Ensure all traces of dirt are removed.
7. Dry Completely: Allow the filter to air dry completely – typically 24-48 hours – before reinstalling. Never reinstall a damp filter.
8. Reinstall: Place the dry filter back into the compartment.

Testing

Turn on the air purifier and observe if airflow has improved. Check for any unusual noises.

Method 2: Cleaning a Permanent Washable Filter

These filters require a more thorough cleaning process.

Diagnosing the Issue

Reduced airflow, visible dirt buildup, or a noticeable odor indicate the filter needs cleaning.

Fix Steps

1. Power Off & Unplug: As always, disconnect the power.
2. Access & Remove: Access and remove the filter as described in Method 1.
3. Rinse Loosely: Gently rinse the filter under lukewarm water to remove loose dust.
4. Soak (Optional): For heavily soiled filters, soak in lukewarm water for 15-30 minutes.
5. Gentle Cleaning: Use a soft brush (like an old toothbrush) and lukewarm water to gently scrub the filter. Avoid harsh chemicals or abrasive cleaners.
6. Thorough Rinse: Rinse thoroughly until the water runs clear.
7. Dry Completely: Allow to air dry completely (24-48 hours) before reinstalling.
8. Reinstall: Place the dry filter back into the compartment.

Testing

Turn on the air purifier and check for improved airflow and reduced odor.

Method 3: Replacing Non-Washable Filters (Activated Carbon & True HEPA)

Activated carbon and most True HEPA filters cannot be washed. Attempting to do so will damage the filter and reduce its effectiveness.

Diagnosing the Issue

Reduced airflow, persistent odors (for carbon filters), or the manufacturer’s recommended replacement timeframe have passed.

Fix Steps

1. Power Off & Unplug: Disconnect the power.
2. Access & Remove: Access and remove the old filter.
3. Install New Filter: Insert the new, appropriately sized filter. Ensure it’s seated correctly.
4. Reset Filter Indicator (If Applicable): Some Honeywell models have a filter replacement indicator light. Consult your owner’s manual for reset instructions.

Testing

Turn on the air purifier and confirm it’s operating correctly.

Preventing Future Filter Issues & Maintenance Advice

Regular maintenance can significantly extend the life of your Honeywell air purifier and maintain optimal performance.

• Regular Vacuuming: Vacuum the exterior of the air purifier weekly to remove dust buildup.
• Pre-Filter Cleaning Schedule: Wash washable pre-filters every 2-4 weeks, depending on your environment.
• Filter Replacement Schedule: Replace activated carbon filters every 3-6 months. Replace True HEPA filters every 6-12 months, or as recommended by the manufacturer.
• Air Quality Monitoring: Be mindful of your indoor air quality. If you notice increased dust or odors, check and clean/replace the filter sooner.
• Avoid Harsh Chemicals: Never use harsh chemicals or abrasive cleaners on any part of the air purifier.

Pro Tips for Honeywell Air Purifier Filter Maintenance

• Filter Life Extension: Running the purifier at a lower fan speed can help extend filter life.
• Consider Air Quality: If you have pets, allergies, or live in a dusty environment, you may need to clean or replace filters more frequently.
• Check for Damage: Inspect filters for tears or damage during cleaning. Replace if damaged.
• Original Filters: Always use genuine Honeywell replacement filters to ensure optimal performance and compatibility.
• Filter Indicator Lights: Pay attention to the filter indicator lights on your purifier. They provide a helpful reminder for maintenance.
