There are several criteria heating experts use to determine how often to change air filters.
Most importantly, how often to change air filters depends on:
Homeowners are encouraged to work with their HVAC contractors to determine exactly how often to change air filters. However, there are general guidelines that homeowners can follow for proper air filter care.
Air filters protect indoor air quality and the heating and air conditioning equipment. Air filters serve as the first line of defense against:
When homeowners know how often to change air filters, they choose to actively maintain home comfort and indoor air quality. Unfortunately, some homeowners do not want to know how often to change air filters. They don’t want to think about spending more money on heating and air conditioning. However, they are risking a lot over very little.
What happens to the home and the air conditioner if homeowners don’t know how often to change air filters? Plenty of things happen, and they cost homeowners big in more ways than one.
On a technical level:
Inside the home:
For the average home without pets, homeowners should change air filters every 90 days or three months. Heating experts have discovered this is the best way to maximize energy efficiency and indoor air quality while minimizing overall costs and maintenance.
If homeowners follow how often to change air filters for average homes, they have:
In addition to finding out how often to change air filters, homeowners can also consult their heating specialists to determine what type of air filter works best for their home needs.
The addition of indoor animals complicates the equation determining how often to change air filters. How?
Indoor animals contribute additional pathogens and particles into home air. The air filter fights against materials like:
If homeowners share the home with one indoor pet, heating contractors recommend changing air filters every 60 days.
If there is more than one indoor animal, change air filters every 20 to 45 days. HVAC contractors recommend the same for those with allergies or other respiratory sensitivities.
Keep in mind that air filters are very good at their jobs. The typical air filter captures up to 50 percent of all airborne particles when the air conditioner or heater runs. The addition of pets increases the amount of particles and pathogens in home air, which means that air filters work harder to remove more.
Owners of vacation homes or homes with only one occupant and no pets are advised to replace air filters every six to 12 months. Because these homes experience little activity and invite few contributors to indoor air quality, air filters do not need to be changed very often.
However, these homeowners run the risk of forgetting how often to change air filters because it is seldom that air filters actually need changing. In order to ensure that these homeowners keep up with how often to change air filters, schedule a reminder or an HVAC maintenance appointment.
Homeowners who are still unsure of how often to change air filters should consult their HVAC contractors.
