Quick Answer: What is a true HEPA vacuum?

What is the difference between HEPA and true HEPA?

The main differences between HEPA-type and True HEPA filter are the filtration efficiency. In general, HEPA-type filter has a 99% efficiency rate of capturing particles as small as 2 microns. True HEPA filter up the game with a better 99.97% efficiency rate at particles as small as 0.3 microns.

What makes a vacuum HEPA certified?

HEPA (High-Efficiency Particulate Air) vacuums differ from conventional vacuums in that they contain filters that are capable of trapping extremely small, micron-sized particles. A true HEPA filter can trap 99.97 percent of all airborne particles larger than 0.3 microns.

Is True HEPA the same as HEPA 13?

True HEPA generally ranges from H10-H12. … Whereas H10-H12 filters only trap 85-99.5% of all particles that are 0.1 microns in diameter, HEPA H13 and H14 trap 99.95% and 99.995% of such particles, respectively.

Are HEPA filter viruses true?

Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes. … It falls squarely within the particle-size range that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above.

What is a true HEPA filter made of?

The True HEPA filter is mostly made of the highly dense paper, which is composed of very thin fibers with distances between 0.3 and 2.0 microns. The fibers are distributed randomly and oriented in all directions.

Is Miele a true HEPA?

Miele Filtration System Uses Higher Standards than HEPA Filtration Standards! On top of 12-Stage Filtration, Miele has what is called a true Sealed System™.

How do I know if my vacuum is HEPA?

Look for the serial number and test results printed on true or absolute HEPA filters. Make sure that the test results at 0.3 microns are 99.97 percent or above. The size of 0.3 microns is the testing standard because most filters will perform better with both smaller and larger particles.

Are Miele Vacuums HEPA certified?

The combination of a sealed system, HEPA filter and AirClean dust bag create the Miele AirClean system, which has been independently certified to exceed U.S. and European HEPA filtration standards. Simply put, Miele vacuums are the most hygienic vacuum cleaners available on the market today.

Do all HEPA filters have fiberglass?

It’s all in the mat and the weave of fibers in the filter itself. HEPA filters use hundreds of thousands of fiberglass fibers—incredibly small and sticky for particles that try to pass through them. This tight weave of fibers then captures particles larger than 0.3 microns in size.
