EPA Certified Wood-Burning Stoves

The EPA has set a PM emission standard for woodstoves at 7.5 grams an hour. Since 1990, any manufactured woodstove must meet the EPA PM emission standards.
No Burn Days

No Burn Days are implemented by states and counties to minimize pollution for a particular time period. On a No Burn Day, it may be illegal to use any wood-burning devices such as fireplaces and woodstoves. These days are enforced under certain weather conditions or when pollution levels are high. Each county and state’s No Burn Day policies are unique and may have different requirements.

States have addressed toxic emissions from wood stoves and fireplaces by:

Restricting the use of fireplaces and wood burning stoves during No Burn Day periods.

Prohibiting the sale, installation, or construction of non-certified wood stoves and fireplaces.

Requiring that all new and used wood stoves and fireplaces meet emissions standards set by the EPA.
