Types of Filters Available for your Furnace

furnace_filters.jpgReusable filters often have a metal or fiberglass frame with fibrous filters that can withstand repeated washings. Disposable filters typically have thick cardboard frames with manmade or natural fibers for the filters. While reusable filters are more cost effective, they are more labor intensive due to the washings you may have to do every month. When choosing a furnace filter, look for the Minimum Efficiency Report Value (MERV) rating. This tells you the effectiveness of the filter in blocking dust and other allergens. The higher the MERV rating, the better the filtration is for the product.
 
You will find four basic types of filters: electrostatic, HEPA (high efficiency particle absorber), mechanical and electronic. Mechanical filters are cheaper and allow smaller particles to escape through and require frequent changing. Electrostatic filters are made from polyester fibers which are charged electrically when air passes through. This static created traps allergens and can go longer between cleaning and replacement. Electronic filters do not have fibers but rather electrically charged mesh which attracts allergens and requires weekly cleaning. HEPA filters are perhaps the best on the market because it exceeds minimum MERV ratings by filtering out 99% of the allergens and particles in the air that passes through it. It is excellent for sick or clinical environments.
