TL;DR
A HEPA vacuum is a vacuum cleaner whose entire airflow exits through a sealed high-efficiency filter capturing 99.97 percent of particles at 0.3 microns, so lead dust, mold spores, and asbestos fibers picked up at the nozzle cannot blow back into the room. The EPA RRP lead rule and abatement protocols specifically require this class of machine, not a shop vacuum with a HEPA-labeled bag, because leakage around an unsealed housing defeats the filter.
