Changing your filter is an important part of maintaining a healthy home. A clean filter will help to improve the air quality in your home, which can lead to a number of health benefits, including reduced allergies and asthma symptoms. It can also help to improve the efficiency of your HVAC system, which can save you money on your energy bills.
You should usually change your filter every 1-3 months, depending on the type of filter you have and how often you use your HVAC system. If you have pets or live in a dusty area, you may need to change your filter more often.
