Key Takeaways

• Clean or replace filters every 3-6 months
• Wipe down sensors and exterior weekly
• Check UV lights and ionizers annually
• Ensure proper airflow around the unit

1. Clean or Replace Filters Regularly

HEPA filters trap dust, pollen, and pet dander but lose efficiency when clogged. For optimal performance:

• Washable filters: Rinse with lukewarm water every 1-2 months and air-dry completely.
• Disposable filters: Replace every 3-6 months (or sooner if you have pets).
• Carbon filters: Refresh by baking at 200°F for 2 hours to reactivate odor absorption.

Pro tip: Mark replacement dates on your calendar—overdue filters can strain the motor.

2. Wipe Down the Exterior and Vents

Dust buildup on vents reduces airflow. Use a microfiber cloth dampened with a non-toxic cleaning solution to:

• Remove dust from intake and exhaust vents
• Clean the control panel with a dry cotton swab
• Vacuum around the base to prevent debris entry

3. Maintain UV-C Lights and Ionizers

If your purifier has germicidal UV-C lights or ionizers:

• Replace UV bulbs annually (even if they still glow)
• Clean ionizing wires monthly with isopropyl alcohol
• Check manufacturer guidelines for safe handling

4. Ensure Proper Airflow

Restricted airflow makes purifiers work harder. Follow these spacing rules:

5. Reset Filter Indicators

Most modern purifiers have filter-life indicators. After maintenance:

• Hold the reset button for 5 seconds
• Note the new filter installation date
• Download the brand’s app for reminders (if available)

6. Check for Air Leaks

Poorly sealed filters let dirty air bypass purification. Test by:

• Running a tissue along filter edges—if it flutters, reseat the filter
• Listening for whistling sounds during operation
• Applying foam tape to seal gaps (if permitted by warranty)

7. Seasonal Deep Cleaning

Every 6 months, perform a thorough cleaning:

• Disassemble removable parts per the manual
• Use compressed air on internal components
• Inspect fan blades for dust accumulation
