All furnaces come with a standard air filter to keep particles from damaging the system. These filters are usually 1/2 to 1 inch thick, and replacing them regularly keeps your system running smoothly. Regular filter changes also bring health benefits by keeping dirt and debris out of the air in your home.
You can buy many levels of air filters. All of them are rated along the MERV scale, from 1 to 16. Their ability to filter the smallest particles of dust mites, pollen, mold spores, pet dander, bacteria, and smoke determine the rating.
How well does your air filter work?
The EPA has guidelines to help you choose the filtration protection best for your home. Match your current filter to the MERV levels below. Would you like more protection?
MERV 1-4: Basic protection. This level protects your furnace from damaging particles, but these filters are not designed to improve indoor air quality.
MERV 7-12: Higher Performance Protection. These filters remove smaller particles like bacteria, viruses, pet dander, and dust mites. The EPA says this type of filter effectively contains most airborne indoor particles. They are also less expensive than true HEPA with similar performance. In addition, they allow your system to have greater airflow and less noise than a true HEPA filter does.
MERV 13-16: Highest Protection. These filters are typically found in hospital and other sterile environments. They are so good at filtering air particles that they can hinder air flow unless they are in a specially-designed system.
What are Media Filters?
Media filters are thick, 5-inch filters with higher MERV ratings. Upgrading your standard filter increases your protection from pollutants and allergens. Our custom-made media filters capture dust, pollen, and virus-sized particles that are flowing through your air.
