Q: What is a HEPA filter?
A: Start with what is the filter in a vacuum cleaner? A filter is a device that traps and blocks small particles from going back into the air. A HEPA filter traps and blocks very small particles from getting back into the air. A certified HEPA filter is required and tested to trap particles as small as .3 microns with 99.97 % efficiency.

Q: What are the sizes and types of particles a true HEPA filter will trap?
A: Human Hair – 70 to 100 microns; Human Sneeze – 10 to 100 microns; Pet Dander - 0.5 to 100 micron; Pollen – 5 to 100 microns; Spores from plants – 6 to 100 microns; Mold – 20 to 200 microns; Smoke - .01 to 1 micron; Dust Mite Debris – 0.5 to 50 microns; Household Dust - .05 to 100 microns; Skin Flakes – 0.4 to 10 microns; Bacteria - .35 to 10 microns.

Q: What is a micron?
A: A micron is a measure of length, one micron equals one-millionth of a meter.

Q: Why is a HEPA filter needed?
A: A HEPA filter is used in a vacuum cleaner to protect the user and the environment when picking up hazardous material. The HEPA filter traps and prevents particles as small as 0.3 microns from being exhausted from the vacuum back out into the air.

Q: Where is a HEPA filter used?
A: In medical research centers, Atomic research centers, nuclear power plants, hospitals, pharmaceutical manufacturing, HAZMAT service contractor (lead paint, asbestos, Anthrax, mold clean up).

Q: What is the difference between a standard filter and a HEPA filter?
A: A standard filter will prevent particles from getting into the air. The HEPA filter will trap particles as small as .3 microns. The standard filter is not a certified HEPA filter. In order for a filter to be rated as type A certified HEPA filter, it must pass very strict government standards to be qualified as a true HEPA filter. Type A HEPA Filters are individually tested according to U.S. Military Standard 282 (MIL-STD-282) and individually certified and labeled with specific test results. Each filter exceeds a minimum efficiency of 99.97% at a particle size of 0.3 microns, with less than 1 inch drop of air pressure. Testing is conducted at 100 CFM for 16” filters and 75 CFM 14” filters.

Q: Are all vacuums that claim to be HEPA really a true HEPA filtered vacuum?
A: If the filter does not contain a certified label with a written efficiency test result measurement, it is not a true HEPA filter.

Q: Are HEPA type filters the same as a true HEPA filter?
A: No, the HEPA type filter might contain similar external qualities to a true HEPA but are not the same. If the filter is not certified and tested according to the requirements of a true HEPA filter it is not a true HEPA filter.

Q: What is a ULPA filter?
A: An UPLA filter is rated at 99.99% efficient in removal of particles to 0.12 microns. Each filter must be labeled with the model number, serial number, efficiency and resistance at tested airflow.

Q: What is the difference between a HEPA filter and a ULPA filter? When living organisms such as bacteria and viruses are trapped in a true HEPA filter, are they killed?
A: No filter media can kill bacteria trapped in the HEPA.

Q: Will a true type A HEPA trap and capture viruses?
A: No, most viruses are smaller than 0.3 microns and the HEPA filter can not trap and capture them.

Q: How many sizes Hepa filters are there?
A: 15 but with modifications
