UV light is used in hospitals, in refrigeration, and you can even find it in a vacuum cleaner. 


If you didn’t already know, ultraviolet light is trending as a sanitizer in hospitals. The technology is used to keep bacteria, mold and mildew from collecting in holy places like hospital beds and food storage refrigerators. I remember working in the kitchen at my camp as a camp counselor and telling all kids, especially teenagers, to not play with the big box in our freezer that kept it from growing mold when it wasn’t being used for the other eight months of the year.

This technology becomes smaller and more accessible and consumers are finding innovative new uses for ultraviolet technology. Some are for your phone and then some are like our vacuums, which combines traditional cleaning methods with this feature. 

An aside about ozone: Understand that any UV light that says it is ‘far-UVC’ produces ozone, which is an environmental pollutant and a respiratory irritant. That’s why the UV light on our vacuum cleaner’s is 254 nm, strong enough to remove bacteria and viruses without causing irritation. If you have a UV light with no protective covering, be sure to cover your skin and eyes while you use it, or step away from the room; even far UV light. All of our vacuums do not produce ozone and have safety sensors to keep you from exposing yourself to this light. That being said, please don’t point it at people or pets. 

But what makes UV light good? And why should you add it to your home cleaning regiment?

Firstly, the average consumer cares about the planet because they live on it and maybe want to keep it nice. After half a century, single use plastics are falling out of fashion. People want alternative methods to disinfecting surfaces and innovative ways to disinfect soft surfaces. Ultraviolet light is one of those alternative disinfecting sources. It doesn’t require spray bottles or sprays and it is a quicker solution than steam cleaning.


Our company, RAYCOP believes in giving people healthier homes and lead healthier lives. Part of that mission is reducing respiratory irritants and avoiding complications when someone is exposed to a virus or bacteria. Most sprays to sanitize fabrics are respiratory irritants, which is a medical way to say they can irritate your respiratory system including your sinuses and lungs. This is the same with pesticides to remove dust mites.  When you’re sick, irritants cause sinusitis, bronchitis and other complications that don’t really help you breathe better in your home.


Ultraviolet light with wavelengths longer than 200nm do not produce ozone and the best wavelength for germicidal exposure is between 250-270nm, with the shorter wavelength being more effective. The longer the exposure, the more effective the UV light is but please, don’t point it at anyone’s skin or eyes.


Hopefully, this answers any questions about the ultraviolet light used in our UV vacuum cleaners to disinfect and remove allergens. If you have more questions you can always contact us to learn more.
