UV is a powerful and proven way to destroy pathogens
Air cleaners, or also known as air purifiers do help protect indoor air. However, to be effective they must be able to remove or filter viruses from the air. Viruses are extremely small ranging in the size of 0.1-1 um. The EPA says it’s important to know that air purifiers can’t remove all the contaminants from the air but this also depends upon the type of filtration system being used. Almost every single air purifier on the market today is designed a little different so the ‘devil is in the details’ when evaluating an indoor air purifier or cleaner.
Commercial-grade air purifiers, which is what we consider our system to be, combines a medial grade synthetic filter, ultraviolent light (UV) and a catalyst to scrub the air of particulates and microorganisms in a continuous basis.
Most air purifiers work by drawing in the air and then passing the air through one or more filters to capture contaminants. Some of the best and most efficient air purifiers use a combination of ion technology, UV light, titanium dioxide (Ti02) in addition to filters. Filters can greatly vary; some are designed to capture larger particulates like the ones you’ll see (usually green) in most home air system returns. Another type of filter incorporates charcoal carbon and are most effective at removing chlorine, sediment, volatile organic compounds (VOCs) and odors. HEPA filters (high efficiency particulate filter) are considered particularly good and are about 99.7% effective at capturing small particles as small as .3 microns. They can filter out dust, mold, pollen and even some bacteria before the air gets returned back into the room.
Some air purifiers are movable (mobile) and used to filter an individual space. Some can be fitted to your HVAC system, but we consider these not effective as air moves around and some viruses like COVID can remain airborne for as long as 2 hours. Our system, which uses a combination of various sterilization technologies is ceiling mounted and consider an “upper air” type of system. Infectious diseases which are airborne are easily spread not low to the floor—but high up closer to the ceiling which is exactly why we designed up to be installed in a ceiling.
Whether you choose our air purifier or another type you should consider the type of filters being used and technology to maintain a safe working environment. UV light along with our filtration system provide a powerful extra layer of protection to defend against infectious airborne pathogens like COVID.
