Air filters make a big difference and impact the world today. If the air filters were unavailable, air would be polluted all over our spaces, and HVAC systems would blow up everywhere. Thanks to technology, we can keep healthy air indoors and help prevent pollution. Check out some essential things you should know about air filters.

What is an Air Filter and its Functions?

An air filter involves a semi-permeable shield installed between the air inside your house and the HVAC system.

As the name suggests, the primary purpose of an air filter is to filter air. While your HVAC system pulls air from your space to warm or cool it, this filter seizes that air in your ductwork. Therefore, the filter acts as a barrier to prevent any foreign material carried by the air from invading your room. These foreign materials include mold spores, pet dander, bunch, dust, and pollen grains. All these materials are captured by the filter; thus, only clean air gets into the house. If you are allergic or asthmatic, air filters are an ideal solution for you.

Why do I Need an Air Filter?

Regardless of whether you have a respiratory medical condition, air filters are essential to install. Besides, indoor air quality is an increasingly significant issue affecting citizens in the United States. Research by EPA shows that the air inside your rooms is significantly more polluted than the air immediately outside the premises. This occurs due to the stagnated air and high concentration of pollutant sources trapped inside a sealed building. An air filter will help you eliminate harmful particles and pollutants that would otherwise be freely suspended in the air inside your house.

Additionally, air filters, such as furnace filters 20x20x4, will enable you to breathe safer and cleaner air, thus promoting your overall home wellness and health. Also, they will prevent gunk from accessing your HVAC systems installed on your premises. The gunks can cause HVAC breakdowns following particle build-up on the system’s coils, which can be expensive to fix.

Maintaining Your Air Filters

Maintenance is essential for any asset you own, regardless of its value. It is important to keep inspecting and changing your filter when need be. Besides, your filter can get filled up with gunk and become less effective in its work. It will become less permeable, restricting enough airflow and forcing the HVAC to work harder. If the HVAC is overworked, it can elevate the power bill while increasing the chances of motor burnout. It is advisable to use pleated air filters and change them at least after three months of use. Thus, you will be guaranteed that your HVAC system is not overworked or spoilt.

Appropriate air filters will also allow you to enjoy health benefits since they capture pathogens like bacteria which can cause infections. Therefore, this will reduce the risk of contracting airborne illnesses like tuberculosis, the common cold, and influenza. If you live in a place with high levels of airborne diseases, ensure you install MERV-13 air filters specifically designed to control airborne bacteria.
