High Efficiency Particulate Air (HEPA) filtration dates back to the 1940s, when this specific filter was used to prevent airborne contaminates from spreading during the Manhattan Project. The system, which traps microscopic particles and eliminates 99.97% of gas particulates with a diameter greater than 0.3 micron, evolved to suit consumers’ needs.
The efficiency of HEPA filters only improves with use, and they are essential for places that require clean-air—such as hospital operating rooms, scientific laboratory’s, clean rooms and NASA. Consumer’s typically associate air filters with cars, vacuums, and vents, but there’s one major industry where filters are essential to production: food.
Without this high-efficiency filter system, consumers would be subjected to a slew of bacteria and other debris. Take yogurt, for example. Whether the product ends up in bottles, cups, or big tubs, it must travel through a yogurt-dispensing machine that has a closed-cell system made up of stainless steel and glass chambers. This positive air system pumps filtered air into the chamber where the yogurt is dispensed then subsequently vacuums it out, which removes all contaminants from the air. Because yogurt contains live cultures, it’s essential to have contaminate-free air to further culture the product.
But HEPA Filtration doesn’t solely apply to dairy products. Industrial, commercial and household equipment use HEPA filters to perform many functions. HEPA filters are used in Cabin Air Filters for off-road vehicles, Laminar Flow Air Hoods for laboratory equipment manufacturers and household air filtration HVAC equipment, and standalone air cleaner appliances.
