HEPA stands for High Efficiency Particulate Arrestance.
HEPA filters are the industry standard best filter to remove allergens from the air. Many background or outdoor allergies cannot be totally removed because the underlying cause; we cannot get rid of the outdoors. HEPA filters are 99.97% efficient at removing particles down to a .3 micron size. Almost all currently known allergens are larger than .3 microns. So a HEPA filter can remove nearly every allergen that passes though the HEPA filter. Outdoor allergens that enter a home or business are mold spores, pollen, dust, grasses, rag weed, danders, and a variety of random particulates.
HEPA filters have were first used in the 1940s at the Manhattan Nuclear site to keep radioactive particles from cross contaminating other areas. By the 1950s, HEPA filters were beginning to be used in the pharmacy and medical industries to reduce contamination. Now, HEPA filters are very common used in many homes and businesses. They are best used for improved air quality by removing the outdoor allergens that we cannot get rid of.
Many models of HEPA filters are available. There are HEPA filters that can be installed to work in conjunction with your HVAC unit so HEPA filtered air can be delivered to every room in your home or business. There are room models so if only one individual suffers from allergies then just their bedrooms can be continually cleaned. There are ceiling mounted HEPA filters that can be installed quickly and affordable into most businesses.
Many individual suffer from allergies specific to a region or location of the office. HEPA filters are needed when the home or building does not have a building problem but the occupant does have allergies or anywhere there is a need for low particulate airflow.
