Bosch Ductless Mini Split System Activated Carbon Freshness Filters

This freshness filter fits inside the pre-molded holder in your Bosch ductless mini split's main screen filter. Activated carbon media helps neutralize odors from tobacco, pets, and cooking. Check your existing screen filter for the built-in holder before ordering. Filter Dimensions: 8.4" x 2" Maintenance & Care Vacuum every two weeks using a soft-bristle brush attachment. Do not wash or rinse with water — this degrades the media and reduces performance. Reinstall only when dry and intact. Replacement Guidance Replace every 6 to 12 months depending on your environment and usage. Homes with pets, smoke, or cooking odors will see faster saturation and should replace closer to the 6-month mark.
