Wood smoke is one of the main sources of air pollution in Washington. Wood stoves, fireplaces, and other wood burning devices put out hundreds of times more air pollution than other sources of heat such as natural gas or electricity.
To protect health, Washington has strict laws about wood stoves and other wood burning devices. Most states use federal Environmental Protection Agency (EPA) emission standards for fine particles to determine which wood burning devices can be sold. To be sold in Washington, all wood burning devices must meet both EPAs standards and Washingtons stricter standards.
