Air filter replacement is a simple yet important part of regular home maintenance. Unfortunately, it’s also a task that many homeowners neglect or simply forget to do.
Why air filter replacement matters
Air filters play an important role in your home’s HVAC system and in improving your indoor air quality.
Air filters keep debris out of your HVAC equipment, keeping your air conditioner and duct system clean. A clean system runs more efficiently, saving you money on your utility bills and reducing the wear and tear that can cause your A/C or heat pump to break down.
As an air filter does its job, the dust and debris that it removes from the air remains trapped in its fibers. The filter eventually becomes clogged and allows less air to pass through. The reduction in airflow likewise cuts down on A/C efficiency, and can cost you more than a replacement air filter would.
Air filter replacement is also good for your health. An old or inefficient air filter contributes to poor indoor air quality, which is a problem that health experts have identified as being a major cause of respiratory illnesses and allergies. Higher-quality air filters can clear your air of many germs and allergens, improving your indoor comfort and reducing your number of sick days.
When to replace air filters
HVAC systems can contain different types of air filters, which are replaced on different schedules.
- The initial 1-inch-thick filter located at the air return register should be replaced every one to three months. If you have indoor pets (which shed fur), or if your HVAC system is working overtime, you’ll need to replace it more often.
- Some systems may have a washable metallic or electrostatic filter, which does not need to be replaced. However, it does need to be cleaned regularly – at least once a year, or whenever it gets dirty.
- High-efficiency air filters, such as HEPA filters, should be replaced at least once a year.
