How to Choose the Correct Fujitsu Mini-Split Healthy Air Filter

Avoid Look-Alikes. Get the Right Fit the First Time.

Fujitsu uses three different Healthy Air Filter sizes, and they are not interchangeable. The part numbers look similar, but the dimensions and holder frames are completely different. If the wrong size shows up, it simply will not install correctly.

Fujitsu Healthy Air Filter Size Guide

UTR-FA16 Series — 8-3/8"

• Part numbers: UTR-FA16, UTR-FA16-2
• Length: 8-3/8"
• Requires OEM holder frame: PN 9332911008
• Common mistake: buying a “similar-looking” generic that is the wrong length.

UTR-FC03 Series — 10-3/4"

• Part numbers: UTR-FC03-2, UTR-FC03-3
• Length: 10-3/4"
• Requires OEM holder frame: PN 9306602017
• Mid-size filter that looks similar to FA16 but will not clip into an FA16 frame
• Generic FC03 “equivalents” often have incorrect width and media tension.

UTR-FA13 Series — 15"

• Part numbers: UTR-FA13, UTR-FA13-2
• Length: 15"
• Includes new OEM filter frames in every set
• Largest option; most commonly counterfeited
• If it does not come with an OEM frame, it is not a genuine FA13 set.

Why These Filters Cannot Be Swapped

Even a small size difference makes the filter unusable. Each Fujitsu Healthy Air Filter series has:

• Different lengths (8-3/8", 10-3/4", 15")
• Different holder frame designs
• Different clip locations
• Model-specific fitment for certain indoor head part numbers

No aftermarket brand can “adapt” these differences without compromising your system.

Beware… Look-Alikes May Cause Breathing Problems!

Generic or “compatible” filters may look similar in photos, but in person they often have:

• Incorrect lengths or widths
• Loose mesh that collapses under airflow
• Weak plastic frames that crack or warp
• Poor-quality media that sheds fibers
• Lower filtration efficiency than genuine Fujitsu OEM filters

These issues lead to dust bypass, coil fouling, and poor indoor air quality — the opposite of what a Healthy Air Filter is supposed to deliver.

OEM Fujitsu filters use precision-cut media, exact frame geometry, and the proper airflow resistance your system was designed for. If clean air matters, look-alikes are not worth the risk.

Replacement Media vs. Frames

• UTR-FA16 & UTR-FC03: replacement media only → you must reuse the correct OEM frame.
• UTR-FA13: includes new OEM frames in every order → an easy way to confirm authenticity.

If your frame is missing or brittle, FA16/FC03 users will need to purchase the correct Fujitsu holder frame to complete the installation.
