How Long Does a Furnace Filter Last?

Changing Furnace Filter

The easiest way to clean the air in your home is to utilize a high quality furnace filter. HVAC professionals say that furnace filters can remove dust, mold, pollen, allergens and dander.

Despite these recommendations, home owners tend to forget about the importance of changing their furnace filter. Those who remember to change their furnace filter are tasked with some very important questions:

  • What type of furnace filter to do I need?
  • How often should I change my filter?
  • Are some filters better than others?

Let's take a closer look at what all homeowners should consider before changing their furnace filters.

Winter Weather Air Quality

In the summer, many homeowners prefer to open their windows to allow fresh air to fill their home. During the winter, your windows will stay closed and you probably aren't willing to let brisk, freezing air into your home. Using a furnace filter will you treat the air quality in your home when you are unable to introduce fresh air during the winter months. For this reason alone, utilizing a new air filter is the best way to increase the air quality in your home.

Evaluating Your Furnace Filter Needs

Your furnace is a costly investment and using a filter can help increase the performance and longevity of your unit. Consumers must evaluate their own personal needs as well as their budget thresholds in order to decide the best filter for their home.

Many furnaces use disposable filters which must be changed between every one and three months. The general rule of thumb is the thicker the filter, the more longevity you gain out of the filter.

Furnace Filters Explained

Many home furnaces will allow you to implement washable or reusable furnace filters. If you use these, you should wash them at least once per month. Be sure to read the documentation included with your new reusable filter.

Most homeowners generally opt for the disposable variation of furnace filters. You typically get what you pay for when it comes to disposable furnace filters. The thinner variation should be discarded every month while the thicker variations are good up to three months.

Measuring Your Furnace Filter

After you determine which filter is best, you may want to note the measurements found on the filter you are replacing and find a furnace filter that is the same length by width size. You may need to make a judgement call on the thickness of filter that will fit in your specific HVAC unit.
