An Air Purifier for a Breathe of Fresh Air
An air purifier works by drawing in dirty air through an inlet vent. Air then passes through a prefilter which traps large particles, then passes through a carbon filter which captures particles and reduces gases and odors. The air then passes through a filter made of tightly woven fibers to capture the smaller particles. This filter is known as a HEPA filter, which is an acronym for high efficiency particulate absorbing. These filters can absorb particles as small as 0.3 micrometers. Some units have electronic ionizers which further capture smaller particles, and particles that have escaped the previous other filters. A fan then recirculates the filtered air back into the room.
