Firemizer is a special mesh of stainless steel alloy fibers designed to optimize the performance of fireplaces. Several independent university tests have demonstrated that Firemizer reduces fuel usage up to 33% and minimizes creosote in the chimney by up to 57%. This patented product is not catalytic and does not contain chemicals, but it slows the air flow to reduce the burn rate, and it conducts heat evenly across the fire to ensure all fuel is burnt and that small pieces of fuel do not fall through the grate. Firemizer is simply placed on the grate, under a wood or coal fuel. It is easily dusted off and it works for about 500 hours.
