Furnace Filter Ratings

A good furnace filter should keep your furnace clean and working properly. Not only will your furnace run longer, but it will keep your home’s heating costs at a minimum. There are a few things to consider when buying a furnace filter. One of the most important is to find a furnace filter that offers the proper amount of air flow for your furnace. In order to ensure a good flow of air, the filter should be a good size to allow for proper ventilation and should contain an appropriate level of air permeability.

Another consideration when purchasing furnace filter is the material that it is made from. When looking at furnace filter ratings, make sure that the furnace filter you select is made of a material that has an air permeability rating higher than six. This means that the filter would be able to pass air quickly through and not be blocked or cut off. Another consideration is the size of the filter. You may want a larger size to allow more air to pass through. Some manufacturers offer multi-packs which contain multiple filters so that you can select which filter suits your needs the best. The amount of air flow is something else that should be considered when purchasing furnace filter ratings.

When purchasing furnace filter ratings, be sure to check the numbers. A high MERV number indicates a high quality filter. A low number indicates a poor quality filter. Be sure to buy your filters from reputable sources. You should also make sure that the furnace filter you are buying is certified by the American Society for Testing and Materials (ASTM). The ASTM can give you a detailed description of the specifications and materials used in the manufacture of the filter. Purchasing a furnace filter with these specifications will ensure that you purchase a filter that will last you a long time and keep your furnace in excellent condition.
