When you choose a new vacuum for your job, do you know the one you get is a Class H certified vacuum or just a vacuum with HEPA filter inside? Do you know that many vacuum clears with HEPA filters offer very poor filtration?
You may notice that there are leaking dust from some areas of your vacuum and make your machine is always dusty, that’s because these vacuums don’t have a completely sealed system. The fine dust blow out of the vacuum and into the air, never make it to the dustbin or bag. These are not real HEPA vacuum.
A HEPA vacuum is DOP tested and certified to meet the HEPA standard EN 60335-2-69 as a whole vacuum. According to the standard, a HEPA filter is only one requirement for a HEPA certified vacuum. Class H refers to the classification of both extraction systems and filters. In other words, it’s not the filter that makes a vacuum HEPA. It’s also important to understand that simply using a HEPA-type bag—or adding a HEPA filter—in a standard vacuum does not mean you’ll get true HEPA performance. HEPA vacuums are sealed and have special filters that clean all of the air drawn into the machine is expelled through the filter, with none of the air leaking past it.
1.What is HEPA filter?
HEPA is an acronym for “high-efficiency particulate air.” Filters meeting the HEPA standard must satisfy certain levels of efficiency. This type of air filter can theoretically remove at least 99.5% or 99.97% of dust, pollen, dirt, mold, bacteria, and any airborne particles with a diameter of 0.3 microns (µm)
2.What is Class H vacuum?
Class ‘H’ – Dust represents a high risk to the operators– H-Class (H13) vacuum / dust extraction pass the 0.3µm DOP test that certifies they capture no less than 99.995% of dust. Type H Industrial Vacuums are designed and tested to meet international standards IEC 60335.2.69. Type H or H Class Industrial Vacuums are used to pick up highest level of Hazardous dust like Asbestos, Silica, Carcinogens, Toxic Chemicals and Pharmaceutical Products.
3.Why you need a HEPA certified vacuum?
The key benefits of H class vacuum cleaners are designed to eliminate highly hazardous material such as asbestos and silica dust on construction in-sites clean.
Concrete cutting, grinding and drilling will release dangerous crystalline silica dust into the air. These dust particles are tiny and you can’t see them, but they are very harmful when inhaled into your lungs. it will causes serious lung disease and lung cancer.
