All the air you breathe in your home passes through your furnace’s air filters first. No matter how clean you keep your house, it is impossible to vacuum and dust every speck of debris – especially if you have small ones and pets. Over time, this pet dander, dust, mould spores, soot, and pollen get trapped in your air filters making it difficult for air to flow through freely. This filter also helps keep your furnace running smoothly by preventing clogs. There are plenty of other benefits to changing your furnace filter regularly.
A clogged filter prevents air from passing through the furnace system, which means it has to work harder. An overworked system is prone to more breakdowns and shortens its life. The furnace’s motor can burn out from overheating. Succumbing to emergency maintenance is costly, and you do not want to be without heat in the winter months.
Family members who suffer from allergies or asthma will feel the brunt of the misery from a dirty air filter. When a filter gets too full of irritants like pet dander and pollen, it does not get filtered adequately and stays in the air in your house. You may notice your family experiencing more congestion or even getting colds more often.
The air inside your home can be worse than the air outside of it. According to American College of Allergists, up to 50% of illnesses are caused or made worse from poor indoor air quality. Portable air units in a room can help that particular space, but you likely spend time at home in more than one room. Your cooling and heating system is designed to move air through millions of cubic square feet. There are furnace filters explicitly designed to target allergens in the air.
Better Air Quality
Improving the cleanliness of the air in your home is especially important if you have infants or seniors with you. These cohorts of people are sensitive to airborne bacteria and irritants. Changing air filters frequently will keep the number of contaminants in your home at a minimum.
How often should you change furnace air filters?
Everyone agrees that changing your air filter is essential, but there is no clear consensus for often it should be changed. The frequency you change your furnace air filters will depend on a few factors.
Occupants with asthma or allergies will need new filters put in more often to ensure the air is free of as many irritants as can be.
Pet owners, smokers, and people living in high traffic/high construction areas will also need to change their filters more often. These variables will increase the amount of debris in your home by tenfold.
The type of filter you purchase will also affect how often you change it. High-efficiency filters collect more particles so they will need to be replaced more often as they get clogged quicker. You can check the guidelines on the packaging for recommendations and adjust accordingly depending on if you also meet the above criteria.
