Washable oven filters are a great way to protect your heating system from dirt and debris. They are reusable and can last for long periods of time, but they do need regular cleaning. The frequency of cleaning depends on the environment and the MERV rating of the filter. When hot air from an oven is blocked, it can cause temperature buildup beyond the capacity of the system.
Air filters are especially important in areas with high levels of airborne irritants, such as smoke, dust, or pet dander. If the filter is not cleaned regularly, it can cause an increase in energy bills as the HVAC system works harder to avoid blockage. You can purchase disposable air filters for your home that only need to be changed periodically. However, if you want to save money and reduce waste, you can opt for a washable air filter.
These filters consist of a mesh fabric with a tightness that determines the MERV rating. Over time, they become clogged with smaller particles and their efficiency decreases. To keep your air filter working properly, you'll need to clean it regularly. If the filter is not cleaned, it can cause mechanical failure or even a complete breakdown of the HVAC system.
Households in areas with high levels of allergens, pollutants, dust mites, mold spores, and debris should consider using a washable air filter to capture these particles in the air.
