Filter Dimensions: 8.4" x 2"

Quantity: 2 filters per order

Compatibility: Fits any Bosch ductless or mini split indoor unit with a pre-molded freshness filter holder in the main screen filter. Check your existing screen filter for the built-in holder before ordering.

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.
