Maintenance & Care

Use a soft-bristle vacuum attachment to clean your screen filters every two weeks. In homes with pets, tobacco use, or high dust loads, gently wash filters with warm soapy water as needed. Always let them dry completely in the shade before reinstalling.

⚠️ Note: Never operate your mini split system without filters installed. Keep an extra set on hand to rotate during cleaning cycles.

Replacement Guidance

These filters are reusable but not permanent. For best airflow and performance, ComfortStar recommends replacing the screen filters every 12 to 24 months, depending on environmental factors and cleaning frequency.

Optional Activated Carbon Freshness Filter

This kit also includes an optional carbon freshness filter designed to install directly into your filter frame. It helps reduce household odors and VOCs, improving indoor air quality between wash cycles.
