Maintaining clean filters in your mini-split air conditioning system isn’t just about efficiency—it’s about safeguarding your health and extending the lifespan of your equipment. At Shenzhen Healthy Filters Co., Ltd, we specialize in advanced filtration solutions, and we’re here to guide you through the simple yet critical process of cleaning your mini-split filters. Follow these steps to ensure optimal performance and air quality.
Why Clean Your Mini-Split Filters?
Dirty filters can lead to:
Reduced airflow: Strains the system, increasing energy bills by up to 15%.
Poor indoor air quality: Trapped dust, pollen, and mold recirculate, triggering allergies.
System breakdowns: Clogged filters cause ice buildup or compressor failure.
Pro Tip: Pair regular cleaning with Healthy Filters’ High-Efficiency Mini-Split Replacement Filters (MERV 11-13) for superior particle capture and 2x longer lifespan.
Tools You’ll Need
Soft-bristle brush or vacuum cleaner
Mild detergent (non-abrasive)
Warm water
Microfiber cloth
Healthy Filters’ Filter Refresh Spray (optional, for antibacterial treatment)
Step-by-Step Cleaning Guide
Step 1: Turn Off the System
Safety first! Power down your mini-split unit to avoid electrical hazards.
Step 2: Remove the Filters
Gently open the front panel of the indoor unit.
Slide out the filters—most mini-splits have 1-2 reusable filters.
Step 3: Dry Cleaning
Use a soft-bristle brush or vacuum (low suction) to remove loose dust and debris.
Healthy Filters Hack: For stubborn particles, tap the filter gently over a trash bin.
Step 4: Deep Wash
Fill a basin with warm water and 1-2 drops of mild dish soap.
Submerge the filter for 10 minutes. Avoid harsh chemicals that degrade filter mesh.
Gently scrub with a soft cloth, then rinse thoroughly under running water.
Step 5: Disinfect (Optional)
Spray Healthy Filters’ Antimicrobial Filter Treatment to eliminate mold and bacteria.
Let air-dry completely in shade—never use direct heat or sunlight!
Step 6: Reinstall Filters
Ensure filters are 100% dry to prevent mildew.
Slide them back into the unit, aligning arrows with airflow directions.
When to Replace Instead of Clean
Even with meticulous care, filters wear out. Replace your mini-split filters if you notice:
Visible damage: Tears, warping, or collapsed pleats.
Persistent odors: Indicates embedded mold or organic buildup.
Short cycles: The system struggles to reach set temperatures.
Upgrade Tip: Healthy Filters’ Anti-Allergy HEPA Mini-Split Filters capture 99.97% of particles as small as 0.3μm—ideal for homes with pets or asthma sufferers.
