Is UVC light safe in Air Purifier

What are UV light air purifiers?

On the electromagnetic spectrum the UV light will fall between visible light and x-rays, this will ultimately be split into different UV light classifications – UVA, UVB, or UVC. These different UV light classifications have most recently been popularly deployed in air purification systems as a means to effectively kill and remove microorganisms like bacteria, viruses, and mold spores from the air of an indoor environment.

Most natural UV light that people encounter in their everyday life comes from the sun. However, according to Live Science, only about 10 percent of sunlight is UV, and only about one-third of this light penetrates the atmosphere reaching the ground. The Environmental Protection Agency (EPA) has developed an Ultraviolet Index (UVI), which is a rating scale with numbers from 1 to 11 that indicate the amount of skin-damaging UV rays reaching the Earth’s surface during the day. The higher the UVI number, the more intense the UV rays you will be exposed to from the sun. There has also been the creation of artificial sources for producing UV radiation, such as tanning booths, black lights, curing lamps, germicidal lamps, mercury vapor lamps, halogen lights, and fluorescent.


How does UV light work

The germicidal properties of sunlight were discovered decades ago, showing the significant capabilities of ultraviolet (UV) light technology for cleaning and sanitizing a broad array of environments. Thus, the addition of UV lights in many different products has been incorporated to give these specific things the ability to kill germs and other microorganisms in the environment. In comparison to other lights that we can visibly see with the human eye, UV lights have a high frequency that affects organisms such as bacteria and mold.

An artificially created UV lamp that is used in a variety of products such as tanning beds, germicidal and curing lamps, and used in air purifiers are used to assist in sterilizing and purifying. These UV lamps come in a variety of sizes and shapes that allow them to be integrated into a wide range of products like air purifiers. When it comes to how these UV lights work when integrated into an air purifier will mostly depend on the type of UV light that is used (UVA, UVB, or UVC) and if these different UV light classifications produce ozone as a byproduct into the environment.


Difference Between UVA UVB and UVC

A major factor to take into account when deciding on an air purifier for your home is to determine if it has UV lights within this device and what kind of UV light it is that it utilized, between UVA, UVB, and UVC. These three types of UV radiation are characterized according to their wavelengths, as well as their different activity when it comes to penetrating the skin. When it comes to determining which type of UV light to have inside of your home’s air purifier, it is best to understand the different effects of each UV light in the environment.


Difference Between UVA UVB and UVCUVA light: UVA is the long-wave light that accounts for about 95% of the UV radiation that reaches the earth. This type of light is often used in tanning beds, as this light can penetrate the skin’s second layer. When it comes to the human skin, UVA light plays a major role in skin aging and wrinkling and contributing to some types of sun damage.

UVB light: UVB light is the major cause behind skin reddening and sunburns that can occur on the human body after sun exposure. This light often leads to damage to the skin’s top layers and is strongly linked to some skin cancers. Additionally, UVB can damage the skin’s DNA and will burn the unprotected skin in as quickly as 15 minutes.

UVC light: The shortest of all UV rays, UVC light never reaches the earth because the ozone absorbs it. This type of light is not usually considered a risk for skin cancer and can be found in many man-made sources like mercury lamps and welding torches.

UVC light technology has been a trusted technology for air purification from hospitals to airports for decades


Is UV C light safe in air purifier?

UV air purifiers, as we discussed earlier, are specifically designed to serve as a layer of protection from potentially harmful pathogens and microorganisms in the air such as bacteria, viruses, and mold spores. In most cases, UV air purifiers will typically utilize UV C lights within their housing, due to the functions that this form of UV light provides when used within this type of an air filtration system.

Is UV C safe in air purifier? UV C lights placed in air purifiers today work through a specific mechanism to act as germicidal irradiation for the air. When air passes through the UV lamps it will disinfect certain microorganisms in the air to aid in the improvement of the indoor air quality. One concern, however, of UV  lights in air purifier is the potential for this light to produce ozone, when produced within certain wavelength ranges.


Selecting a UV-C Air Purifier That Does Not Produce Ozone

When it comes to selecting an air purifier for your home, nobody wants to place an air device into their home that can potentially release or emit a harmful substance into their air, such as ozone. UVC lights or germicidal UV are at a much more specific wavelength than what is termed “UV” broadly, which encompasses the wavelength of 100-380 nm. UVC are low-pressure lamps, more like a fluorescent lamp, with a specific wavelength of 253.7 nm (1182.5 THz). The production of ozone from UV lights, the light wavelength would need to be at a specific range of 160 to 240 nm. Some air purifiers will fall between this range where ozone will eventually be produced into the airspace of the environment, this can be a potential hazard to both your indoor environment and the health of those who are exposed to this byproduct in the air, particularly in higher levels.

The MagComb UV Air Purifier, on the other hand, is an air purification system that utilizes ultraviolet germicidal radiation (UV C) but this light has been tested to determine that this specific UV C light does not produce ozone into the air. The MagCombUV Air Purifier has a wavelength of 254 nm, which is outside the ozone producing range. Additionally, the UV C lights contained in this air purifier is effectively able to shine on the collection of microorganisms such as mold spores, bacteria, and viruses, that are collected on top of the hospital-grade HEPA filter, situated below the UV C lamps within this air purifier.


Selecting a UV-C Air Purifier That Does Not Release UV light

MagComb UVC air purifier use a ReflectTech mirror coating to protect the people from UVC light, and the UVC light is “0” leaking, in the same time , when applied to stainless steel increases the reflectiveness by 30%. This means that the UV-C light is magnified inside of the sterilizing chamber. The widened chamber slows down the air flow while exposing particles to maximum UV dosage . The coating also prevents particles from attaching to the sides of the chamber.
