Levoit air purifiers are popular choices for improving indoor air quality in American homes. Cleaning and maintaining filters properly helps maximize performance and extend the life of the unit. This guide covers how to clean Levoit filters, when to replace them, and best practices for different Levoit models.
Quick Answer
Most Levoit purifiers require washing a washable pre-filter regularly and replacing the HEPA or carbon filters on a schedule. Use a soft brush to remove dust, rinse the pre-filter under running water, and let it dry completely before reassembly. Always follow the model’s manual for replacement intervals.
What You’ll Need
- Levoit Core 300 washable pre-filter
- Levoit Core 300 replacement filter set
- Levoit LV-H132 replacement filter
- Levoit air purifier HEPA filter 3 pack
- Levoit filter cleaning brush
Before You Start
Before cleaning, unplug the purifier and remove it from any damp or humid areas. Check your model’s manual for exact filter parts and stepwise instructions. Never run water or cleaning solutions on a sealed motor or electronics. Allow any washed components to dry completely in a well-ventilated area before reinstalling. Expect 15–30 minutes for basic cleanup, and up to a few hours for thorough pre-filter drying.
Step-By-Step: How To Clean Levoit Filters
- Unplug the unit and remove the front grill to access the filters.
- Gently remove the washable pre-filter from the intake side.
- Use the Levoit filter cleaning brush to loosen dust on the pre-filter, then rinse under cool running water.
- Shake off excess water and let the pre-filter air-dry completely indoors away from direct sunlight.
- Inspect the HEPA/carbon filters. If they appear deeply soiled, damaged, or emit noticeable odors, plan for replacement rather than washing.
- Install the cleaned pre-filter back into place if the model supports reusing it; otherwise, replace it with the Levoit Core 300 washable pre-filter as needed.
- Insert a fresh HEPA filter (or a set from the Levoit air purifier HEPA filter 3 pack) according to the orientation marks on the filter and unit.
- Close the grill securely and power on the purifier to confirm proper airflow and no unusual noises.
- Reset any filter reminder indicators on the unit if your model includes this feature.
- Record the date of cleaning and replacement to track when the next maintenance is due.
- For environments with heavy dust or pet dander, repeat shallow cleanings of the pre-filter every 1–3 months and replace main filters on a 6–12 month cycle depending on usage.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Weak airflow after cleaning | Pre-filter not seated correctly or drying incomplete | Re-seat pre-filter, ensure it’s fully dry before use | Dry thoroughly; verify fit during reassembly |
| Unpleasant odor after replacement | Old carbon/HEPA filter still present or misfit | Replace with fresh filter pack; confirm orientation | Change filters at recommended intervals |
| Noise or vibrations | Grill misalignment or loose filter | Refit grill tightly and check for loose components | Handle parts gently during maintenance |
| Indicator shows filter needs replacement | Filter life exceeded | Install new Levoit replacement filter set | Monitor usage and replace as scheduled |
Common Mistakes
- Using hot water or cleaning agents on filters
- Plugging in the purifier with a damp pre-filter or wet interior
- Forgetting to dry the washable pre-filter before reassembly
- Using non-original or incompatible replacement filters
Tips For Best Results
- Place the purifier in an open area with at least a few inches of clearance on all sides for optimal airflow.
- Schedule regular pre-filter cleanings every 1–3 months, more often in dusty homes.
- Keep a simple log of cleaning and filter replacement dates to stay on track with maintenance.
- Use genuine Levoit replacement filter sets and the official Core 300 filters to ensure fit and performance.
Call A Professional
Stop and contact a professional if the purifier shows persistent abnormal noises, electrical smells, or if the unit fails to power on after maintenance. If the housing is damaged or the filters do not fit properly despite following instructions, seek service guidance from Levoit support or an authorized repair center.

Buying Guide
Choosing the right Levoit filter setup involves considering size, noise, energy use, controls, and placement. For most bedrooms and living spaces, a compact model with a quiet operation and easy filter access offers the best balance. Look for a filter set that includes both HEPA and carbon components to maximize particulate capture and odor reduction. If the device supports multiple filter stages, confirm compatibility with the Levoit Core 300 washable pre-filter and the replacement filters in the product lineup. In spaces with pet dander or heavy dust, a higher-capacity filter pack and simpler maintenance chores can simplify upkeep. Always compare the model’s filter life and replacement intervals to your environment, then select a kit that aligns with your cleaning goals and routine.
