Great Product!!

The firemizer REALLY works. Not only does the fire burn longer, there is little to clean up. I use firestarters NOT newspaper so all that's left is a fine ash. I always keep one in the fireplace and one in stock. A MUST have for those who use their fireplaces on a regular basis.More > < Less

We were given a firemizer last year for Christmas. We liked it so much, found out where our friend bought it and again are enjoying wood saving with our Firemizer.More > < Less

I have to say had VERY LOW expectations.... I was pleasantly surprised. It definitely made our fire last longer. So far so so good


This is my second time purchase

I was so impressed the first time I bought this that when the old one was ready to be replaced I purchased it again. I have an old 1830's coal parlor stove. With this in the bottom I can burn wood and it lasts twice as long. Great product.More > < Less

Same amount of wood. Longer-lasting fire.

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.
