What is HEPA Filtration and why is it the best?

HEPA was invented by the U.S. government’s Department of Energy and was developed for use in nuclear facilities in the 1940s. Today, it is one of the most powerful vacuum filters available, removing 99.97% of air particles that are at least 0.3 microns in size. 


This article will explore HEPA filtration in detail, how it’s made and why it works so well. 

What is a HEPA filter?

HEPA stands for high-efficiency particulate air (filter). It was invented back in the 1940s when scientists were working on developing the atomic bomb. It consists of randomly aligned fibers that are made from glass or synthetic materials, similar to the material used in quick-dry t-shirts. 


The most important characteristic of HEPA filters is that they are very effective at capturing virtually every size of particle. They are able to capture pollen, pet dander, allergens, bacteria, and even air-born viruses. They can trap particles that have a diameter of less than 2.5 micrometers, known as PM2.5. These particles are 100 times thinner than human hair. 

When is a filter considered a HEPA filter?

Even though these filters were created a long time ago, the term “HEPA” can only be used under a strict set of requirements. They must be able to remove 99.97% of particles and contaminants from the air. Any less than that and they can only be categorized as “EPA filters” or “efficient particulate air filters”.
