How to Clean Your Mini Split Air Filters

Modified on Wed, 2 Apr at 1:27 PM

Why Filter Cleaning Matters

Cleaning your Senville mini split’s air filters is essential for keeping your system running efficiently and maintaining healthy indoor air quality. Dirty filters can cause poor airflow, reduced cooling or heating performance, and even system errors or shutdowns.

How Often Should You Clean Them?

Every 30–60 days for most homes.
Every 2–4 weeks if you have pets, allergies, or live in a dusty environment.

What You'll Need

Soft brush or vacuum with brush attachment
Mild soap (optional)
Warm water
Clean, dry towel

Step-by-Step: Cleaning the Air Filters

Step 1: Power Off the Unit

Turn off the mini split using the remote, and switch off the circuit breaker for safety.

Step 2: Open the Front Panel

Gently lift the front cover of the indoor unit until it clicks into place in the open position.

Step 3: Remove the Filters

Slide out the mesh filters — usually located just behind the front panel. Take note of how they are positioned so you can reinstall them easily.

Step 4: Clean the Filters

Light cleaning: Use a vacuum cleaner with a soft brush attachment to remove dust and debris.
Deep cleaning: Wash the filters in warm water with a small amount of mild soap. Rinse thoroughly.

Step 5: Dry the Filters

Let the filters air dry completely before reinstalling. Do not use a hair dryer, heater, or place them in direct sunlight to speed up drying.

Step 6: Reinstall the Filters

Slide the filters back into place, close the front panel securely, and turn the power back on.

Helpful Tips

Don’t run the system without filters — this can damage internal components.
Set a recurring reminder to clean your filters monthly during heavy-use seasons.
Some models may include secondary filters (e.g., carbon or ion filters). Check your manual for specific instructions.
