It is interesting information. Due to the back draft pumping carbon monoxide and radon throughout your ventilation system, Energy Star says that it's essential to cover the filter slot after replacing the filter. The size of Filter for furnace should be an accurate size too. There's a brand new product called Filter Lock that's easy to use and saves energy. http://www.airsponge.com
