  • What is ultraviolet light?

    Ultraviolet, or UV light is invisible to the human eye, but can be found just to the right of visible light on the light spectrum. UV light is measured in nanometers, a unit of measure representing a billionth of a meter, and its wavelength typically lies between 100 and 400 nanometers.

    Scientists divide UV light into three spectrums: UVA, which many of us know as "black light", UVB, which is used in tanning beds, and UV-C, the germ-killing light employed by Halo in its cleaning appliances. Learn more on our Technology page.

  • How long does it take for the Halo™ Ultraviolet Vacuum to kill germs?

    In most cases, less than one second! Engage the Halo™ Ultraviolet Vacuum's UV-C activation switch as you vacuum and you're issuing an almost immediate "death sentence" for the unseen and unwanted germs that have been hiding on your home's floors.

  • How does ultraviolet light kill dust mites, bacteria, MRSA, mold and viruses?

    Ultraviolet light kills potentially dangerous germs in your home by disrupting the DNA structure of their cells - or simply breaking down the germs' make-up. The Ohio State University and University of Arizona researchers have made sure that our vacuums produce the exact amount of "irradiance" (or rays) to kill germs instantly, safely and effectively with no more effort than regular vacuuming.

  • Is ultraviolet light safe for use in the home?

    Absolutely. Germicidal ultraviolet light is an accepted, safe and reliable way to kill unseen organisms, including the dust mites, bacteria, germs and viruses that live and thrive in carpet. Hospitals have safely employed germicidal UV light to sterilize surgical instruments, and many municipalities employ UV light to sterilize their water.

    Halo is the first electrical appliance maker to harness this environmentally safe, chemical-free technology for use in the home - but many rural dwellers that rely upon a well as their primary source of drinking water are already familiar with the pathogen-destroying power of UV water-disinfection solutions.

  • Can using Halo UV products ever harm me or my family?

    We've designed Halo™ UV products with safe operation and maintenance in mind. Use your Halo as directed, and dust mites, viruses, mold and bacteria will be the only things harmed in the vacuuming of your home.

    ETL requires that the amount of UV light coming outside of the 4 walls of the base of the unit not be harmful to a user or anybody else in the room. The way they tested that was to place a UV light sensor 1-2 inches away from the side of the base and measure how much UV light was coming out of the unit. Keep in mind that they took the measurements on a hard surface where you would have maximum reflection of UV light off the floor, as opposed to on carpet where likely 99+% of the UV light would be absorbed by the carpet. The test that Halo passed was that a person could hold their face 1-2 inches from the unit for 8 hours and still have no harmful effects.

  • Will the use of ultraviolet light hurt my eyes?

    There are various safety mechanisms employed in our vacuums that prevent the end-user's inadvertent exposure to any ultraviolet light. There is no need to wear any special eyewear or be concerned of damage to your eyes, even though you may see it glowing out from under the powerhead.

  • How do I know it works?

    See more proof in our Science and Technology section.

  • Are your products considered green?

    Green products can fall under a large umbrella, but the common thread is that they all have a very low negative impact on the environment. Halo products are green products. Our vacuums use no chemicals, run efficiently and are registered with the EPA. The ultraviolet light we employ to kill micro-organisms in your home is simply harnessed sunlight.
