Wood burning stoves are a timeless source of heat and ambiance, but they often produce smoke and particulate matter. To mitigate these emissions and improve indoor air quality, filters for wood burning stoves can be a valuable addition. In this article, we’ll provide a concise and clear overview of wood stove filters, explaining their purpose, types, installation, and maintenance.
- Purpose of Wood Stove Filters
Wood stove filters, commonly referred to as stovepipe filters or flue filters, serve a crucial purpose. They are designed to reduce the emission of fine particulate matter and smoke into the atmosphere and, by extension, your living space. This not only enhances air quality but also minimizes the impact of your wood burning stove on the environment.
- Types of Wood Stove Filters
There are primarily two types of filters used in conjunction with wood burning stoves:
a. Catalytic Combustor Filters: These filters employ a catalytic process to promote more complete combustion. They are typically installed inside the stove and require periodic replacement (usually every 2-5 years). Catalytic combustor filters can significantly reduce emissions but may necessitate a higher upfront investment.
b. Particle Filters: Particle filters, also known as stovepipe filters, are installed in the stovepipe or flue system. They capture particulate matter and smoke as they exit the stove. These filters are generally more affordable and require occasional cleaning or replacement.
- Installation
Installing a filter for your wood burning stove is a straightforward process, but it’s crucial to follow manufacturer instructions carefully. Here’s a general installation procedure for both catalytic combustor and particle filters:
a. Catalytic Combustor Filters: These are typically positioned inside the stove. To install, remove the old combustor (if present) and replace it with the new one according to the manufacturer’s guidelines. Make sure to seal any gaps to prevent smoke leakage.
b. Particle Filters (Stovepipe Filters): These filters are installed in the stovepipe or flue. Ensure your stovepipe is clean and in good condition. Insert the filter into the stovepipe, securing it according to the filter’s specific installation instructions. Regularly inspect and clean or replace as necessary.
- Maintenance
Proper maintenance of wood stove filters is essential for their effectiveness. Here’s a brief overview of maintenance for both filter types:
a. Catalytic Combustor Filters: Monitor the condition of the combustor regularly. Clean it as recommended by the manufacturer, usually when you notice a significant reduction in stove efficiency. Replacement will be necessary every few years, depending on usage.
b. Particle Filters (Stovepipe Filters): Routinely check for creosote buildup on particle filters. Clean them or replace them when you notice reduced airflow. It’s recommended to inspect and clean these filters during your regular wood stove maintenance routine.
Conclusion
Filters for wood burning stoves are a valuable addition for enhancing indoor air quality and minimizing environmental impact. Understanding the purpose, types, proper installation, and maintenance of these filters is key to reaping their benefits. Whether you opt for catalytic combustor filters or particle filters, ensure you follow manufacturer instructions diligently to make the most of your wood stove and keep the air in your home clean and safe.
