How Often Should I Change My Furnace Filters?

Indoor air quality is a concern to homeowners in the Baltimore area.  Given the amount of time your family spends indoors, due to seasonally cool fall, winter and early spring, the air you breathe needs to be free of dust and dirt particles, fresh and as allergen free as possible.  Good quality indoor air goes a long way in preventing asthma flare-ups, allergies, and even sinus issues.

You can ensure your indoor air quality is at its best by making sure that your home heating system has an excellent filtration capability.  And the best way to keep your system filtering out dust, dirt and debris from the air is by changing your furnace filter regularly, before dust and dirt invade your home.

Replacing your filter is essential in maintaining not only your indoor air quality, but also the performance of your heating system.  Filtering much of the debris out of the air keeps your furnace operating efficiently, placing no undue strain on your system due to clogged ducts, vents, and an overburdened motor.  By replacing your furnace filter regularly, you’ll keep your air clean, your family healthy, and your heating system operational for years to come.

Does Size Make A Difference In Efficiency?

In a word, yes.  The filter common a few decades ago were considerably smaller than those used in most homes today.  Although the 1” pleated filters are still available, many furnace manufacturers recommend  3” pleated filters.  The smaller pleated filters are adept at preventing large particles from disrupting your heating system, but not as efficient at preventing allergens and smaller particles from circulating throughout your home.

For the 3” filters, it’s recommended that you replace your furnace filter every three months on average.  If your filter is a HEPA, anti-allergen filter, replace every 1-2 months, depending on usage.

How Often Should I Clean Reusable Air Filters?

Although reusable filters are, as the name implies, reusable, they should be replaced when they become less easy to clean.   Clean your reusable filter once a month, using a hose to rinse and allowing it to dry completely before replacing.

Does Changing my Furnace Filters Improve Efficiency?

When wondering how often you should change your furnace filter, you really need to keep in mind your filter’s main job.  Your filter, while keeping the air in your home clean, also prevents particles of debris from entering your heating system and causing problems with furnace efficiency by clogging ducts, inhibiting output, and, possibly causing unnecessary wear and tear on your furnace’s components. Changing the filter every 1 to 3 months will keep your system operating at full efficiency.

How Often Should I Change Allergen Filters?

In order for your allergen, or HEPA filter, to work optimally, providing you continual protection from allergens and indoor pollutants, you need to change your filter regularly, meaning every 1 to 3 months depending on how often you run your system.  Obviously, in colder periods, you’ll need to change your filter more often.
