What is a HEPA Vacuum?
A vacuum cleaner can only be called a HEPA Vacuum if it has a true HEPA filter in it. HEPA filtration is specifically used in vacuum cleaners, air filters, negative air machines and respirator filter cartridges. A HEPA filter can trap a large number of very small particles that other vacuum cleaners would simply recirculate back into the air of your home.
According to NIOSH (National Institute for Occupational Safety and Health), a true HEPA filter is one that can trap 99.97 percent of dust particles that are 0.3 microns in diameter. This does not mean that HEPA filters cannot trap particles smaller than 0.3 microns, because they do! A HEPA filter is comprised of a mat of interlaced dense fibers arranged in many folds and layers to create a fibrous maze to trap particles. An air flow source, typically a blower fan, pushes the particles through this dense web of filter media and traps particles smaller than 0.3 microns by a combination of three different mechanisms; direct impaction, interception and diffusion.
What scenarios require a HEPA Vacuum?
HEPA vacuums and HEPA air filtration are used in many places, including:
- Medical settings
- Remediation jobsites for mold, asbestos or lead
- Pharmaceutical settings
- Electrical and manufacturing plants
- Offices and waiting rooms
- Residential homes
What are the health benefits of using a HEPA Vacuum?
One of the biggest benefits of a HEPA filter vacuum is its ability to improve the air quality. The HEPA vacuum not only removes large particles, but also removes potentially harmful micro-particles that are floating around in the air. Removing these pollutants improves the overall air quality. For those with allergies or conditions like asthma, removing these particulates from the air over time can make a huge difference.
HEPA filtration is mandatory for asbestos and lead abatement or mold remediation projects. Our best selling abatement HEPA vacuum is the GD-930 vacuum by Nilfisk – shop today!
