What is a HEPA filter?
Definition of a HEPA filter
A HEPA (High-Efficiency Particulate Air) filter is a type of air filter that is commonly used to improve indoor air quality. HEPA filters are designed to capture and remove a wide range of particles from the air, including dust, pollen, pet dander, mold spores, and other airborne pollutants that can have negative effects on respiratory health. These filters are made up of a dense mat of randomly arranged fibers that trap airborne particles as they pass through, effectively purifying the air and making it safer to breathe.
How does a HEPA filter work?
HEPA filters work based on a few key principles. First, the filter is made up of a dense mat of fibers that create a maze-like structure. This structure allows the filter to capture and trap particles as air passes through, effectively removing them from the air. Second, the fibers used in HEPA filters are very fine, with a diameter of less than one micron. This small size allows the filter to capture even the smallest of particles, such as viruses and bacteria. Finally, the filter itself is designed to have a large surface area, ensuring that there is enough space for particles to be trapped and preventing the filter from clogging too quickly.
