Factors To Consider When Selecting A Furnace Filter

A furnace filter can last anywhere from one to six months. There are many factors that determine how long it will last such as the type of filter it is, how often you use your furnace, and whether you have pets. When it is time for you to replace your furnace filter, you have some decisions to make. Not all filters are the same. As such, you need to look at more than just the measurements to help you find the furnace filter that makes the most sense for you. Here are some factors to keep in mind as you shop for a furnace filter.

Your Budget

One of the factors that you should keep in mind as you should for a furnace filter is your budget. Filters can range in price based on the type of filter you are buying. A woven fiberglass filter is generally less expensive than pleated or electrostatic filters. However, they have to be replaced more often. If you are on a tight budget though, this may be the perfect type of filter for you.

Any Allergies or Breathing Conditions

An electrostatic furnace filter may be the most expensive type of filter. But it can effectively filter out smaller particles than pleated or woven fiberglass filters. If you have allergies or anyone in your home has a breathing condition, such as asthma, filtering out these particles can make life easier. It can help ensure that allergies or breathing issues are not exacerbated. Additionally, some furnace filters contain allergen filters that filter out specific types of allergens, such as pollen. Consider one of these types of filters for increased protection.

The MERV Rating

The last factor you should keep in mind as you shop for a new furnace filter is what the minimum efficiency reporting value, or MERV, rating of the filter is. A MERV rating can range anywhere from one to 16. A rating of one means the filter filters less than 10 percent of air pollutants that pass through it. A rating of 16 means the filter can remove up to 85 percent of air pollutants that pass through it. As such, the higher the rating, the more efficient the filter is. Paying attention to the MERV rating will help you find a filter that can efficiently remove air pollutants as air passes through your furnace.

There are many factors to consider as you shop for a furnace filter. Always consider your budget, whether anyone has breathing issues or allergies in your home, and the filter's MERV rating to find the filter that will best meet your needs.
