For people with asthma, allergies or other respiratory problems, keeping the air inside your house clean is a never-ending task. Dust mites, stray allergens and other irritants can make your home feel like a battleground. But having the right tools by your side can save you from hours of cleaning frustration. Enter the HEPA vacuum.
To understand the health benefits of a HEPA vacuum cleaner, you need to understand what HEPA stands for. HEPA is an acronym. It stands for high efficiency particulate air filter. A HEPA filter traps very small dust and allergen particles, whereas a vacuum without a HEPA ends up just recirculating those tiny particles in the air. The U.S. Department of Energy sets the standards for a filter to be considered a HEPA filter. According to those standards, a filter must remove from the air that passes through the filter 99.97 percent of all particles larger than .3 micrometres. To put that in perspective, the average human hair is 100 micrometers wide. Take a look at a HEPA filter. Look at all the layers and the curvy contours. The allergens end up trapped in the various layers of those fibers.
