A Necessary Evil
I wish it weren't necessary to purchase these filters, because they are expensive and don't last particularly long. However, they are absolutely necessary. I learned the hard way with my first Mr. Buddy, which I ran with standard unfiltered propane canisters, which the Mr. Buddy is designed for. In a season, the heater was hopelessly clogged and useless. These filters will prevent that from happening. The problem, unfortunately, is that, with the filters installed, standard canisters don't fit into the heater compartments that are designed to hold them. The central promise of the Mr. Buddy—portability—is thus dead on arrival.
