How Often Should You Change Your HVAC Filter?

Regular Replacements is Essential to Clean Air

Many people may overlook air filters as a seemingly insignificant HVAC part. However, air filters are one of the most important components of your HVAC system. Not only do they help keep your air clean, but they also help increase the efficiency of your system. Without air filters, it would be hard to achieve the healthy, comfortable home you desire.

Keeping dust, allergens, and other particles at bay is essential for protecting the most important parts of your HVAC system from getting clogged. If you don’t replace your air filter regularly, not only are you allowing dangerous particles to circulate in your home, but you’re also letting them settle on the delicate fins and coils of your system. To avoid this, you need to replace your air filter on a regular basis, taking into account several factors that determine how often you should do this.

How Do Air Filters Works?

Air filter materials are varied, but their primary purpose is always the same. Air filters prevent dirt, dust, pollen, and other debris from entering your HVAC system. Depending on your system and filter’s rating, your filter may even capture bacteria and viruses. Make sure to check your unit’s requirements when choosing new filters to ensure they are made of adequate material and have sufficient filtering capacity.

When Should Air Filter Be Replaced?

The air filter should be replaced at least once every six months, but most filters will need to be replaced much sooner. The regularity with which you should replace your air filter depends on several factors, including:

  • How often do you use your HVAC system
  • Whether or not you have pets
  • The air quality in your neighborhood
  • The size of your home
  • Allergies in your home

If you have a fiberglass filter, then you may need to replace it as often as every month. On the other hand, air filters made from higher quality materials usually last longer.

Clean Filters Improve Efficiency

A dirty air filter significantly increases the workload of your HVAC system, and if left unchecked, can even release the debris it has collected. HEPA filters may also put a strain on your system due to their superior filtration capabilities. When selecting a new air filter, it is important to consider the level of filtration that best meets your home and budget needs.

Picking and Replacing Filters

The easiest way to replace your air filter will be to have a professional do it for you. Most HVAC companies will clean or replace your air filter as a regular part of their HVAC maintenance services. They will know what filter is best for your system and when its next cleaning or replacement should occur. Of course, you may not need a full maintenance service performed on your HVAC every single month. Still, an occasional check-in with a local HVAC company like Swan Plumbing, Heating, & Air of Denver will set you up for continued performance from your HVAC system.
