Why are HEPA Filters Top-Rated?
HEPA (high-efficiency particulate air) describes filters designed to capture 99.7 percent of all particles 0.3 microns or smaller (too small to see, but the perfect size to penetrate your lungs). This size covers all common allergens, from mold and animal dander to dust mites and pollen, along with some small particles from smoke and pollution.
How Do Carbon Filters Work?
Carbon filters trap harmful particles and odors through a process called adsorption, which occurs when molecules attach to the outside of a surface, rather than being soaked into it. The more porous the activated carbon, the better, as this will increase the amount of surface space available for contaminants to latch onto when air passes through the filter.
What is UV-C?
UV-C air purifiers are designed to use short-wave ultraviolet light (UV-C light) to inactivate airborne pathogens and microorganisms like mold, bacteria and viruses. They have the same ultimate goal of all air purifiers: to reduce indoor air pollutants. The technology is also referred to as UV germicidal irradiation, or UVGI air purifiers. This is different from other air purifier technologies that contain UV light technology but do not use it directly against air pollutants.
