In this article, we’ll delve into the world of HEPA filtration, explore the different levels of HEPA, and examine the HEPA level of Dyson air purifiers.
Understanding HEPA Filtration
Before we dive into the specifics of Dyson’s HEPA level, let’s first understand the concept of HEPA filtration. HEPA, short for High Efficiency Particulate Air, is a type of air filter designed to capture extremely small particles, including dust, pollen, smoke, and other airborne pollutants. The filters are composed of a mat of randomly arranged fibers, which trap particles as air passes through, allowing clean air to circulate back into the environment.
The HEPA standard was first developed in the 1950s by the United States Army, with the primary goal of capturing radioactive particles. Today, HEPA filters are used in a wide range of applications, from residential air purifiers to medical facilities, cars, and even spacecraft.
The Different Levels of HEPA
When it comes to HEPA filters, not all are created equal. The efficiency of a HEPA filter is measured by its ability to capture particles of a specific size. The most common types of HEPA filters are:
True HEPA
True HEPA filters are designed to capture 99.97% of particles as small as 0.3 microns. This means that only 0.03% of particles smaller than 0.3 microns can pass through the filter. True HEPA filters are the most effective at capturing allergens, bacteria, and viruses.
HEPA-type
HEPA-type filters, on the other hand, are designed to capture 95-99% of particles as small as 0.3 microns. While they are less effective than True HEPA filters, they are still capable of capturing a significant portion of airborne pollutants.
Super HEPA
Super HEPA filters are designed to capture 99.99% of particles as small as 0.1 microns. These filters are even more effective than True HEPA filters, making them ideal for applications that require the highest level of air purification.
