The Shadiness of UV Light: UV Tech in Air Purifiers 

An air purifier is a simple machine. Its basic function is to maintain healthy indoor air quality by taking in dirty air and pushing out clean air into your home. All an air purifier really needs in order to do this is a quality motor and a reliable high efficiency air filter. 

Don’t get fooled by trendy new technology that air purifier brands are trying to push onto customers, including UV light. An air purifier will clean your indoor air efficiently and safely with a high quality motor and a high efficiency air filter. 

The best way to research if an air purifier will successfully clean your area is by looking at the independent CADR rating that measures air flow created by the motor and the filter efficiency. 

Air Purifier Technology

At Oransi, we’re always working to bring you the best value for performance. We've also seen others pursue innovation for innovation’s sake. That is, it doesn’t really seem to benefit you, the customer. 

HEPA filter based media is one of those things that’s tried and true. It works extraordinarily well at filtering out even the finest of particles. And it’s been a proven safe technology since the 1940s when it was invented.

At best, unproven technologies don’t work — at worst, they can do more damage than good. Patented air purifier technology is trying to make an unnecessary, more expensive, and potentially unsafe solution happen. 

UV light is one of those filtration technologies to consider cautiously. It can be a hazardous technology when not properly installed or implemented. 

Several schools, businesses, and customers invested in UV light air purifiers to “kill” COVID bacteria, but unfortunately, there’s no independent conclusive evidence that ultraviolet light can kill virus particles. 

It's suspect technology because in order to properly disinfect the air of airborne virus particles, it would need much longer exposure time to the UV light than is feasible. 

In fact, there have been reports of this technology malfunctioning in schools, and some schools have decided to remove these devices for the safety of their staff and students. Exposure to UV light itself is dangerous, so it's best to avoid this technology for general use and go with the one proven safe filtration method: a  high efficiency air filter and a strong quality motor. 

Best For Mold Remediation, Not General Air Cleaning

One reason to consider UV disinfection is if you need to destroy mold spores. UV light requires a long exposure time to destroy particles so using UV light technology for issues like dust, pollen, and virus particles, which move very quickly, isn’t effective. But it can be effective for mold spores. 

For general air cleaning and purification, that's not solely for mold problems, you'll want to go with a  high efficiency air filter to feel a real difference in your indoor air quality. 

Trust HEPA Filter Based Media for Indoor Air Quality

Experts like the CDC, EPA, and Harvard School of Public Health recommend HEPA based media filtration over any other “air purifier tech” out there. It’s the only proven technology to clean your indoor air. 

In fact, we were honored to be seen inside the U.S. National Institute of Health (NIH) and the National Institute of Allergy and Infectious Diseases (NIAID) offices in the 2023 PBS documentary about Dr. Anthony Fauci. And very grateful for the customer who spotted us while watching and let us know! 

When it comes to cleaning your air, you can trust a  high efficiency air filter and strong motor to get the job done well. To avoid potential safety issues, UV light technology is best left for the professionals doing mold remediation.
