Not all vacuums are created equal. Just because a vacuum cleaner has a HEPA filter does not mean it is “true HEPA.”
All vacuum cleaners are motorized and produce air flow that conveys soils into a collection receptacle, filtering the air before it is exhausted back into the room. Mold and mold spores, human and animal dander, dust mite feces, insect parts, lead dust, carbon and cooking residues are captured and filtered out by high quality vacuum cleaners featuring “true HEPA” filtration. HEPA (High Efficiency Particulate Air Filter) are certified to trap 99.97% of all particles down to 0.3 microns. The smallest particle that the human eye can see is about 25 microns in diameter. A true HEPA vacuum cleaner actually cleans the air while it cleans the carpet.
