Air filters on average needs to be changed monthly. Some factors that can make it where you need to change your air filter more often are as follows:
- Number of people living in the house
- Where you live
The more dust or debris in the air and in the house the more often the filter needs to be changed. Regular filter changing is important to ensure your unit runs efficiently. Another important reason is that it maintains better air quality in your home.
If you check your filter and it looks dirty or you can’t remember when the last time was that you changed it then it’s time to switch it out.
