HEPA filters are an effective way to reduce airborne particles, including allergens and asthma triggers. In this section, we will explore what HEPA filters are, how they work, and the different types available.
What Is a HEPA Filter?
HEPA stands for High-Efficiency Particulate Air filter. HEPA filters are designed to capture particles as small as 0.3 microns in diameter. This includes common allergens such as pollen, pet dander, and dust mites, as well as larger particles like mold spores and bacteria. HEPA filters are commonly used in air purifiers, vacuum cleaners, and HVAC systems.
How HEPA Filters Work
HEPA filters work by forcing air through a dense mesh of fibers. As the air passes through the filter, particles become trapped in the fibers. HEPA filters use three mechanisms to capture particles: interception, impaction, and diffusion. Interception occurs when a particle comes into contact with a fiber and sticks to it. Impaction occurs when a particle is too large to follow the air stream and collides with a fiber. Diffusion occurs when small particles move erratically and collide with fibers.
Types of HEPA Filters
There are three types of HEPA filters: True HEPA, HEPA-like, and HEPA-style. True HEPA filters are the most efficient type, capturing 99.97% of particles as small as 0.3 microns. HEPA-like filters are less efficient, capturing only a portion of particles. HEPA-style filters are the least efficient, capturing only larger particles.
