Having an HVAC system in your home allows you to heat and cool the air in your home as necessary. Besides the system heating and cooling your home, all most homeowners know about these systems is that they have a pesky filter that needs to be changed regularly. But why? What does an air filter do, and why is it important? Let’s break down these questions and give you some insight into why those are important in your HVAC system.
Air filters are square sheets containing a mix of fiberglass, polyester, and cotton. When your HVAC system pulls in air it often contains pollutants, allergens, dust, grime, and dirt. The purpose of the filter is to catch those substances to ensure your home’s air is safe to breathe. This is especially important, and makes changing the air filter regularly vital, if you live in a busy city or near working farmland where the air outside your home contains more of the particles that you don’t want to breathe in.
Not only is the outside air dirty, but people and pets produce a lot of dust, dander, and hair with them wherever they go. Your HVAC filter takes that “dirty” air inside your home and filters it to remove all the impurities that people and pets bring.
So why is it important that these filters be in place? Anyone with seasonal allergies can tell you that it makes a world of difference. Your home is your sanctuary and where you should be safe to breathe freely without concern for your health. Modern homes are so well sealed that they trap pollutants. Without a filter to remove these from the air your home would just get dirtier and dirtier and you would see dust and pet hair on every flat surface. Not only would this make your home look dirtier, but it would also provide a health hazard especially for anyone with allergies or breathing difficulties.
So now that you know what an air filter does, we recommend changing your filter 2 to 4 times a year to ensure your HVAC system is always working properly and doing its job.
