How Often Should You Change Your Air Filter?

When it comes to keeping your home's air clean and free of allergens, the air filter plays an important role. But how often should you replace your air filter? This depends on several factors, including the type of filter you use and the environment in which you live.

Different Types of Air Filters

There are two main types of air filters: disposable and reusable. Disposable filters are made from paper or fiberglass and need to be changed every 30-90 days. Reusable filters, on the other hand, are made from metal mesh or synthetic material and can last up to a year or longer depending on their type and where they're used.

Factors That Affect Replacement Frequency

The frequency with which you need to replace your air filter is affected by several things, such as:

  • Type of filter: Disposable filters require more frequent replacement than reusable ones.
  • Environment: If you live in an area with a lot of dust or have pets, then you may need to change your air filter more often.
  • Usage: If you run your AC frequently, then it's likely that your air filter will need replacing sooner.
  • Quality: Higher quality filters tend to last longer than lower quality ones.

Signs That It Is Time To Replace Your Air Filter

If any of these signs appear then it may be time for a new air filter:

  • Clogged Filter: If there is a lot of dirt or dust clogging up the filter then it needs replacing.
  • Decreased airflow: If there is less airflow coming out from the vents then this could indicate a clogged or dirty air filter.
  • High energy bills: A dirty air filter can cause your HVAC system to work harder resulting in higher energy bills.
  • Unpleasant odors: If there are unpleasant odors coming from inside your home then this could mean that it's time for a new air filter.
