The EcoFire Super-Grate's heated air jets burn wood nearly 800 degrees hotter than the average fire, which increases radiant heat and produces less smoke, says the maker. Woodside, Calif.-based Andiron Technologies claims its product reduces particulate matter and carbon monoxide emissions by 60 percent and 80 percent, respectively. Forcing more air to the base of the fire raises the temperature to 1,800 degrees Fahrenheit, resulting in a cleaner, slower burn. The unit comes in four sizes to fit fireplaces of various widths and depths and is available with a left- or right-mounted fan housing. Andiron Technologies, 650.330.1051
