Buyer's Guide
Planning to buy a furnace filter?
When considering which furnace filter to buy, it is important to think about the size of your furnace, the type of filter you need, and the frequency with which you will need to replace the filter. The size of your furnace will dictate the size of the filter you need. Be sure to measure your furnace before purchasing a filter so that you get the right size. The type of filter you need will depend on the type of furnace you have. If you have a standard furnace, you will need a standard pleated filter. If you have a high-efficiency furnace, you will need a special high-efficiency filter. The frequency with which you will need to replace your furnace filter will depend on how often you use your furnace and the type of filter you have. Standard pleated filters should be replaced every 3 months. High-efficiency filters may need to be replaced more or less frequently, depending on the manufacturer's recommendations.Rankings
