Grant W –
This filter broke with a loud pop in my tent. I was using all Mr.Heater parts to run the Buddy off of a 20lb tank. I shut off the tank, shut off the heater, and left the tent, about 20 minutes later, I heard a loud pop and found the “filter” had blown itself apart. Unit will snap back together once re-assembled, but will blow apart as soon as pressure is re-applied.Filter is a giant baffle, there is no actual filter element, just a cavity for particulate to get caught in before feeding the buddy heater.
