Kills Coronavirus...

Particle’s Gentle UV (a low dose blend of UV-A light) is proven to eliminate 99.9% of SARS-CoV-2, the coronavirus that causes COVID-19.

...and other germs

Particle also kills many other germs like E.Coli, Salmonella, and Staphylococcus.

Safe for You

Particle’s smart sensor turns off Gentle UV whenever you’re nearby, so you should never be exposed to UV light.

Even if you were somehow exposed, Particle’s Gentle UV is 9,000x safer than traditional UV-C disinfecting products, according to the ICNIRP* guidelines. A full 8-hour day under Gentle UV light is the equivalent of 2 minutes in sunlight.

*International Commission on Non-Ionizing Radiation Protection is the world’s authority on UV safety.

Independently verified

Texas Biomedical Research Institute recently performed rigorous testing of Particle and its efficacy to combat SARS-CoV-2, the virus that causes COVID-19.

Texas Biomed is an independent, non-profit biomedical research institute specializing in infectious diseases. Home to a CDC-regulated biosafety level-4 laboratory, Texas Biomed develops vaccines and therapies to successfully treat some of the world’s deadliest diseases, including COVID-19. Texas Biomed performs both independent, grant-funded research and contract research for several national agencies and is supported by philanthropic organizations, including the Bill & Melinda Gates Foundation.

The Department of Biology at Central Washington University recently tested Particle’s effectiveness against several strains of bacteria, such as Escherichia coli O157:H7, Staphylococcus aureus (MRSA), Salmonella enterica, and Bacillus cereus.

CWU is a distinguished public university in Ellensburg, Washington, whose Department of Biology focuses on all elements of biology relevant to the individual and to our society. The team of scientists responsible for testing Particle has deep expertise in microbial ecology and physiology, which are crucial for the control of infectious diseases.

Smart sensing technology

Two modes to control the white light

Standard Mode

Switch Particle on to illuminate and disinfect your space. When you’re nearby, Gentle UV turns off. When you leave, Gentle UV turns back on and continues disinfecting.

Lifestyle Mode

The white light turns on when you’re nearby. When you leave, the white light turns off after 5 minutes. Gentle UV operates the same as Standard Mode.
