Way too expensive. We bought mesh paint roller grids at $3 each, straightened the legs before putting them in the bottom of our wood stove, and got better results. They last longer, too.More > < Less

It only lasted for maybe 20 hours worth of fires before it started to fall apart. Nice concept; terrible quality. Very disappointed. First grommet purchase turns out to be a dud.More > < Less

I gave this to my cousin for his birthday to use in his wood stove that he uses for heat. The weather is now cold enough for him to try it out. He said when he uses it, the fire goes out because it just doesn't get enough air to keep it going. I'm embarrassed because I don't like to give someone a gift that doesn't work.More > < Less

About Firemizer

Fires Burn Better

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.
