With spring just around the corner, it’s a smart time to replace one of the most essential components of your HVAC system – the air filter. An HVAC filters most basic function is to remove impurities from the air within your home and protect your HVAC system from damage. But there is more than one option when it comes to choosing a filter.
Fiberglass
These are the most common and inexpensive filters. Fiberglass air filters are effective in trapping large air particles, but they’re not the best choice for catching dust and other pollutants like pet dander from indoor air. If you have allergies or other common respiratory problems, you should consider using a higher-grade filter.
Pleated
Pleated filters are remarkably effective at trapping small particles and provide better filtration than fiberglass, as they’re made from dense screens of cotton or polyester. The pleats provide more surface area for filtration and allow for more air contaminates to be trapped. Both fiberglass and pleated filters should be changed out at least once every three months.
Washable (Reusable)
Washable, reusable air filters can save you money in the long run even though they cost more than disposable fiberglass or pleated filters. They can be easily cleaned by hosing them down or vacuumed to remove particle buildup. In other words, you don’t need to replace them. But, it’s important to clean them according to the recommended schedule provided by the manufacturer. You’ll want to ensure the filter is completely dry before using it to prevent mold and bacteria growth.
Electrostatic
Electrostatic air filters trap more particles, including smoke, dust, and pollen particulates through electrostatic charge. This type of filter prevents these particulates from entering your home. Electrostatic filters can be one-time disposable use or washable. The washable electrostatic air filters are eco-friendly but can lose their electrostatic charge over time resulting in decreased ability to catch small particles.
HEPA
High efficiency particulate air (HEPA) filters are a great choice for homeowners with allergies, respiratory issues, or compromised immune systems. They consistently remove up to 99.97% of household contaminants 0.3 microns or larger in size. The US Department of Energy recommends this type of filter in homes and businesses.
UV
UV filters eliminate microscopic elements by using ultraviolet light to kill viruses, bacteria, or mold that can be harmful. This type of filter has become more popular during COVID-19 and can kill microorganisms that other filters cannot. However, it’s important to note that UV filters will not remove dust or most allergens. The best way to clean your home air is a system using both a UV filter and a standard air filter.
