If you’ve been vacuum shopping recently, it’s likely that you ran into a vacuum model or two being advertised as having a “HEPA filter,” or High Efficiency Particulate Air filter.
By overlapping breathable materials with randomly-arranged fibers, HEPA filters capture much smaller particles than conventional air filters. A filter must be able to catch particles of 0.3 micrometers or smaller to be considered a HEPA filter in the industry, effectively immobilizing 99.97% of all airborne particles.
The great benefit to HEPA filters is that they are able to trap many of the microorganisms that spread disease, like bacteria and viruses. Interestingly, they were invented to filter irradiated particles during The Manhattan Project. Since then, they’ve seen wide use on commercial airliners, in hospitals, and now, in vacuums.
Although first developed in the 1940′s, they have only grown in popularity in recent decades as awareness about household cleanliness and disease prevention have risen. HEPA vacuum filters are also recommended for trapping extra fine dust and pollens that contribute to allergies and asthma.
Okay, and now for the industry insider tips on HEPA filters: First, a HEPA filter can only be as good as the vacuum filtration system of which it is a part. For a HEPA vacuum filter to truly work, all the air leaving the vacuum must pass through the filter. That means that the seal around the HEPA filter must be air tight. Learn as much about a vacuums HEPA filter system before purchase if health issues are a primary purchasing concern.
Also, not all HEPA filters are alike. Some filters have even better collection ratings for medical applications. Spend a little extra time finding out the details to get the best HEPA filter available for your vacuum model.
HEPA filters might be the new big thing when it comes to vacuum cleaners and air filtration, but the history of the vacuum cleaner is actually rooted in addressing health concerns.
The man pictured above is James Murray Spangler–inventor of the first upright vacuum cleaner–and the prototype which he originally adapted from a soap box, a broom handle, and an old pillow case. Spangler suspected a carpet sweeper as the cause of his asthma woes and set out to find a suction-oriented solution. The iconic design of the upright household vacuum became the result of his efforts, a design he later sold to the Hoover vacuum company.
