Sustainable Living

Fire Optimizer

starting at $29.95
Fires burn longer, warmer, and cleaner when they’re built on top of a Firemizer. This reusable mat is made from a stainless steel mesh that distributes heat evenly so wood lasts up to one-third longer. Cut the mat to fit the bottom of your fireplace, wood pellet stove, or wood burning stove. It reduces even the smallest pieces of fuel into fine ash.
Sustainable Living


If you heat your home with a wood burning stove or insert—or even if you just enjoy your fireplace or fire pit from time to time—a Firemizer should be on the bottom of it. Your wood will last up to 33% percent longer. Firemizer is a reusable mat made of stainless steel mesh. It spreads heat more evenly and burns even the smallest pieces of fuel down to ash that you just brush away between fires. The amount of fuel you use—and the amount of creosote in your chimney—are reduced, and burn time is increased by up to one-third. Wherever you use the Firemizer, trim it to fit using a standard wire cutter. Wear gloves when you handle it, though, to avoid steel splinters. Then enjoy a more efficiently burning fire that won’t burn through your heating budget.
