Great Purchase

3/4/2018 by Patricia L

I bought this for our son who is moving to a new place that has a wood burning fireplace. My husband and I have been using the Firemizer for at least five years at our home in our fireplace. It does what it says it does...keeps embers up where the wood is burning and our fires burn longer and more efficiently. It lasts a couple of seasons for us. Truly worth buying!More > < Less

I bought this for a gift for my son in law who loves his fireplace. I saw how much work he puts into getting the wood, chopping, stacking, carrying it in to the house etc. And thought this would be the perfect gift. He LOVES it!! It works exactly as advertised!More > < Less

This works great for my cabin fireplace in North Carolina. It helps the wood burn better and longer and it helps give off more heat.


Very practical

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.
