The Mitsubishi Mr. Slim MSZ-FX Series is the premium cold climate wall mount indoor unit for Mitsubishi multi-zone heat pump systems. Featuring Mitsubishi's advanced 3D i-see Sensor®, Dual Barrier Fusion anti-contaminant coating, triple-action filtration, and built-in Wi-Fi with the Mitsubishi Comfort App — the FX Series delivers a superior level of comfort and air quality that the standard GX Series does not offer. Available in 6,000 to 18,000 BTU. Compatible with Mitsubishi MXZ standard multi-zone and PUMY commercial multi-zone outdoor units. Price includes installation of the indoor unit and up to 20 ft of lineset per head. Outdoor unit sold separately.

⚠️ Indoor Unit Only — Outdoor Unit Not Included. This page is for the MSZ-FX indoor unit only. To build a complete multi-zone system, purchase one compatible MXZ or PUMY outdoor unit separately and add one indoor unit per zone. Contact Bison Air to confirm compatibility and total system design before ordering.
💡 FX Series vs GX Series — How They Compare
Feature FX Series (This Page — Premium) GX Series (Standard)
BTU Range 6K–18K BTU 6K–24K BTU
Built-in Wi-Fi ✅ Yes — Comfort App ✅ Yes — Comfort App
3D i-see Sensor® ✅ Yes — occupancy & comfort sensing ❌ Not included
Dual Barrier Fusion ✅ Anti-contaminant coating — stays cleaner longer ❌ Not included
Filtration Nano Platinum + deodorizing + anti-allergy enzyme Standard filter
Best For Rooms where air quality, allergen control & occupancy sensing matter Standard comfort zones — great value with built-in Wi-Fi up to 24K
Price Higher — reflects premium features Lower

If budget matters more than advanced sensors and filtration, the GX Series is the right choice. If you want the best comfort and air quality Mitsubishi offers in a wall mount, the FX is worth the premium. Contact Bison Air if you are unsure.
