Whole House HEPA Filtration System
Air pollution doesn’t just happen outside. Indoor air pollution from dust mites and dirt from outdoors can irritate your lungs and contribute to allergies and asthma. HEPA filters can eliminate allergens from the air through a multi-layer filtration system.
First, there are one or more outer filters that work like sieves to stop the larger particles of dirt, dust, and hair. Inside those filters, there is a concertina of what looks like folded paper designed to trap the smaller particles. The paper is actually a mat of very dense glass fibers and, unlike the gauze, it doesn’t simply filter out small dust particles like a sieve. Instead, it uses three different mechanisms to catch dust particles as they pass through in the moving airstream. At high air speeds, some particles are caught and trapped as they smash directly into the fibers, while others snag on the fibers as they try to brush by. At lower air speeds, dust particles tend to wander about more randomly through the filter and may stick to its fibers as they do so.
Together, these three mechanisms allow HEPA filters to catch particles that are both larger and smaller than a certain target size.
