News: UV Sanitizing Light Kills Viruses and Bacteria


The world is in a panic with the Covid-19 virus killing hundreds of thousands of people world-wide. So it’s with keen interest to find research showing how UV light can kill them to a certain degree.

Raycop’s been around for years with a product that does just this – kill bacteria and viruses with UV rays. And no, you can’t use it in your body (as some world leader has suggested – without thinking) to disinfect yourself.

Kitasato Research Center Finds UVC Wavelength Light Effective to Kill Viruses

SAN RAMON, CALIF. (March 19, 2020) – According to the Kitasato Research Center for Environmental Science, using an Ultraviolet C (UVC) sanitizing light can help kill viruses such as influenza. Commissioned by RAYCOP, a maker of UV allergen vacuums, the research [pdf] noted that UVC wavelength light, as opposed to UVA or UVB, is the most effective against viruses*.

Immunologist Dr. Michael Lee founded RAYCOP to help people make their homes healthier and to mitigate allergies. He sought products he could recommend to his patients with the goal of preventing the onset of allergies and avoiding the need to take medications. To that end, Dr. Lee invented RayClean Technology©, which captures 99.9% of potentially harmful microorganisms that you can’t see such as viruses, bacteria and dust mites.

The RN utilizes RayClean Technology to remove 99.9% of bacteria and viruses from fabrics within a few seconds.

“My goal was to help my patients by creating a safe and effective UV light sanitizing vacuum for the home,” says Dr. Lee. “Keeping homes healthier is of the utmost importance – especially now – and our RayClean Technology has been in use since 2005. This technology also greatly reduces allergens in the home, lessening symptoms year-round for allergy sufferers.”

“Our mission is to clean the unseen,” explains Hirobumi Suzuki, CEO, RAYCOP North America. “We want to make your home a safer and cleaner place to live.”

RAYCOP’s hand-held UV allergen vacuum, the RN, includes a four-stage filtration system. This system incorporates a high-efficiency particulate air filter, UVC ultraviolet light, optimized suction and a dual-motor brush head. The RN utilizes RayClean Technology to remove 99.9% of bacteria and viruses from fabrics within a few seconds. According to a study by the National Center for Biotechnology Information, UVC light also reduces the hatchability of dust mite eggs. This in turn reduces future allergy-causing dust mite populations.

Founded by a medical doctor in 2005, RAYCOP is a leading consumer health product manufacturer focused on improving the quality of life for allergy sufferers. Headquartered in Tokyo, Japan, RAYCOP is the pioneer in ultraviolet light allergen vacuums with more than six million units sold to date. RAYCOP products are currently sold in many countries around the world. In 2016, RAYCOP strengthened its global presence with the addition of a North American headquarters in the San Francisco Bay Area. To learn more, please visit
