Do I need a special adapter or regulator?

Do I need a special regulator or filter to use my Gas Growler with my stove or heater?

Not usually. Most propane stoves and heaters come with a regulator that is either high or low pressure, and which is located either in-line or at the gas flow controller. We only know of one manufacturer who recommends adding a filter for their product, and they sell a filter for their devices.

When in doubt, consult your heater manufacturer for their recommendation (if you use our 2-in-1 heater/stove, you don't need anything else!).
