What you should know about Air Filters & Allergies.

The importance of changing air filters in your home is something that many people tend to underestimate. Air filters are either disposable or reusable, and you’ll need to replace or clean them every one to three months. They’ll aid in improving the efficiency of your heating and cooling system as well as your indoor air quality. If someone in your household suffers from allergies or asthma, you want to be sure to replace or clean them regularly. 

You Need Special Air Filters to Prevent Allergies

It’s a common misconception that regular HVAC filters can protect you against allergies. In actuality, to avoid allergy attacks you’ll need special air filters. The purpose of standard HVAC air filters is to prevent dust from entering the equipment and keep it performing efficiently. These filters help remove dust from the air when replaced or cleaned regularly, but they do little to capture the microscopic particles that trigger allergy symptoms. 

Standard Paper Filters Can’t Catch Allergens

You typically use paper filters in furnaces and air conditioners. These filters are made to trap larger particles, such as dust that can settle on the motor and fans. If you don’t replace the filters, dust can accumulate, reducing the efficiency of your equipment. The contaminants will also get circulated through the ducts and blown back into your home. 

High-energy particulate air filters, or HEPA filters, are designed to trap very small particles and allergens, helping to keep your indoor air clean. These filters are made from densely-packed layers of glass fibers. High-quality filters can trap at least 99 percent of dust, pollen and dust particles in your living spaces. 

You Need to Replace the Filter More Frequently

It’s essential to understand the importance of changing air filters in the home and when it’s best to do so. Compared to ordinary paper HVAC filters, a HEPA air filter requires more frequent replacement, especially during allergy season. You may need to change it at least every other month or sometimes even sooner, depending on your area. Your HVAC technician can help you determine the best replacement schedule based on your equipment and location.
