Understanding Your LG Air Purifier Filter Types
LG air purifiers utilize several types of filters, each requiring a slightly different cleaning approach. Knowing which filter type you have is crucial for effective maintenance.
- Pre-Filter: Catches large particles like dust, pet hair, and pollen. Typically washable.
- HEPA Filter: Captures 99.97% of particles 0.3 microns in size, including dust mites, mold spores, and bacteria. Usually not washable and requires replacement.
- Charcoal Filter (Deodorization Filter): Absorbs odors, gases, and VOCs. Generally not washable and needs replacement.
- UV-Nano Filter (Select Models): Uses UV light to kill bacteria and viruses. This isn’t a filter you clean, but it’s part of the overall system.
- Washable Dust Collector Filter (Select Models): Acts as a first line of defense, trapping larger particles. Designed for repeated washing.
How to Clean Your LG Air Purifier Filters: A Step-by-Step Guide
The cleaning process varies based on the filter type. Here’s a breakdown for each:
Method 1: Cleaning the Pre-Filter & Washable Dust Collector Filter
These filters are designed to be cleaned regularly.
Diagnosing the Issue
A clogged pre-filter will reduce airflow and potentially strain the fan. Visible dust buildup is a clear indicator it’s time for a cleaning.
Fix Steps
- Unplug the Air Purifier: Important: Always disconnect the power before cleaning.
- Remove the Filter: Refer to your LG air purifier’s user manual for specific instructions on filter removal. Usually, this involves opening a panel on the back or side of the unit.
- Vacuum the Filter: Use a brush attachment on your vacuum cleaner to gently remove loose dust and debris.
- Wash the Filter (if applicable – Washable Dust Collector Filter): Fill a sink or basin with lukewarm water and a mild detergent. Gently wash the filter, avoiding harsh scrubbing.
- Rinse Thoroughly: Rinse the filter under clean, running water until all soap residue is removed.
- Dry Completely: Allow the filter to completely air dry before reinstalling. Important: Never reinstall a damp filter. This can damage the unit and promote mold growth.
- Reinstall the Filter: Once dry, carefully reinstall the filter according to the user manual.
Testing
Turn on the air purifier and check for improved airflow and reduced noise levels.
Method 2: Maintaining the HEPA & Charcoal Filters
These filters are not washable and require replacement.
Diagnosing the Issue
Reduced airflow, noticeable odors (for charcoal filters), or a “Filter Replacement” indicator light on your air purifier signal the need for replacement.
Fix Steps
- Unplug the Air Purifier: Important: Always disconnect the power before handling filters.
- Remove the Filter: Follow the instructions in your user manual.
- Inspect the Filter: Examine the filter for visible dirt, debris, or discoloration.
- Replace the Filter: Purchase a genuine LG replacement filter compatible with your model. Installing a non-genuine filter can compromise performance and potentially damage the unit.
- Reset the Filter Indicator: Most LG air purifiers have a filter replacement indicator that needs to be reset after installing a new filter. Refer to your user manual for instructions.
Testing
Turn on the air purifier and confirm the “Filter Replacement” indicator is off. Observe for improved air quality and reduced odors.
Preventing Future Filter Issues & Maintenance Advice
Proactive maintenance can extend the life of your filters and ensure optimal air purifier performance.
- Regular Vacuuming: Vacuum the area around your air purifier frequently to reduce dust intake.
- Pre-Filter Cleaning Schedule: Clean the pre-filter every 2-4 weeks, depending on usage and air quality.
- HEPA/Charcoal Filter Replacement Schedule: Replace HEPA and charcoal filters every 6-12 months, or as indicated by the air purifier’s filter replacement indicator.
- Avoid Placing Near Sources of Dust: Don’t place the air purifier near dusty areas like uncarpeted floors or construction zones.
- Proper Ventilation: Ensure adequate ventilation in the room to prevent excessive dust buildup.
Pro Tips for LG Air Purifier Maintenance
- Use Genuine LG Filters: While aftermarket filters may be cheaper, they often don’t meet LG’s performance standards and can damage your unit.
- Check the Airflow Path: Regularly inspect the airflow path for obstructions, such as furniture or curtains.
- Don’t Use Harsh Chemicals: Avoid using harsh chemicals or abrasive cleaners on any of the filters.
- Washable Filters – Gentle is Key: When washing washable filters, avoid aggressive scrubbing which can damage the filter material.
- Filter Reset Reminder: Set a calendar reminder to check and replace filters on schedule.
- Consider Air Quality: If you live in an area with poor air quality, you may need to clean or replace filters more frequently.
- UV-Nano Filter Care: For models with UV-Nano, periodically wipe down the exterior of the unit with a damp cloth.
When to Call a Professional
While most LG air purifier maintenance can be done yourself, there are times when professional help is needed.
- Unusual Noises: Loud or persistent noises coming from the air purifier could indicate a mechanical issue.
- Burning Smell: A burning smell is a serious safety concern and requires immediate attention.
- Persistent Malfunctions: If you’ve tried troubleshooting and the air purifier still isn’t working correctly.
- Internal Damage: If you suspect internal damage to the unit.
Finding a qualified technician: Contact LG customer support for a list of authorized service providers in your area. Repair costs vary depending on the issue, but expect to pay between $50-$200 for a basic repair. Warranty considerations apply, so always check your warranty status first.
