Mr. Heater F273699 Universal Propane Fuel Filter for Portable Buddy and Big Buddy Heaters

The Mr. Heater Universal Fuel Filter (part number F273699) is a genuine OEM accessory for the Mr. Heater line of portable propane heaters. It installs inline between the heater and a 20 lb propane cylinder or bulk tank to trap oil, moisture, and debris before they reach the regulator and burner assembly.

This filter is intended for use with the Portable Buddy, Big Buddy, Hunting Buddy, and Tough Buddy portable heaters. Its cast aluminum body is built for the cold-weather and outdoor conditions these heaters are designed for - hunting blinds, ice fishing shelters, campers, workshops, and remote job sites.

Adding a fuel filter when running these heaters off a refillable propane tank helps protect the regulator and burner components from contaminants carried in the gas stream, supporting clean ignition and longer service life of the heater. Mr. Heater replacement filter, part number F273699.
