What are HEPA Vacuums?

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. To illustrate how small this is, a human red blood cell is usually between 6 and 8 microns wide.

For Mold Remediation, these vacuums are a vital tool in removing loose particulate prior to any application of chemicals or demolition, as to minimize spread contamination.  HEPA vacuums are also recommended for cleanup of dust that may have settled on surfaces outside the remediation area.  Care must be taken to assure that the filter is properly seated in the vacuum so that all the air must pass through the filter. When changing the vacuum filter, remediators should wear PPE to prevent exposure to the mold that has been captured. The filter and contents of the HEPA vacuum must be disposed of in well-sealed plastic bags.
