How Do UV Air Purifiers Work?

What are UV Air Purifiers

What is a UV Air Purifier?  

The Environmental Protection Agency (EPA) found that even the tiniest difference in indoor air quality can, in fact, affect your health. That’s why it’s no surprise when the Air Quality Life Index (AQLI) shows that countries where air pollution is worsened, such as China and India tend to trend towards shorter life expectancies on average. And this makes UV air purifiers that much more important, especially considering the threat poised by a viral pandemic.

The good news is that numerous studies have shown that air purifiers with UV-C light are capable of killing mold, mildew, bacteria and viruses

A UV air sanitizer can improve your indoor quality resulting in better respiratory health, especially for people with preexisting conditions. For instance, air purifiers claim to be able to reduce asthma reactions by destroying airborne triggers. 

Can UV Air Purifiers Make a Significant Difference in Your Health? 

Is the air quality in your home or office bad enough to merit active prevention? 

According to the EPA, the top five air pollution problems are found inside residential and commercial buildings. In fact, the EPA also reported that 90% of people spend most of their time indoors, where air pollutants are 2 – 5 times higher than they are outside. But what are the specific air quality problems? 

Excessive moisture, volatile organic compounds (VOCs), combustion products, radon, pesticides, dust particles, viruses, and bacteria have all been proven to affect human health. Moreover, the associated symptoms such as odors, dampness, and stale air will make wherever you work and live considerably less comfortable. 

Most of the time these symptoms are undetectable. But with an ultraviolet air purifier as a solution, you won’t have to worry about these common and potentially dangerous air pollutants. To understand why, let’s take a deeper look at how a UV air filtration system works. 

How Does A UV Air Cleaner Work?

Imagine a vacuum that sucks in airborne pathogens instead of dust on the floor. When operational, it sits casually in the corner of your living room or office, constantly replacing stale air with fresh air. When air passes through it, the UV lights instantly kill the pathogens floating in the air. 

Its effectiveness depends on four factors: 

  • Exposure time to UV-Light
  • Proximity to UV-Light
  • CFM or Air Changes Per Hour (how fast it replaces air in your room)
  • Specifically fine-tuned air purifier UV light wavelength (see further below for a deeper explanation)

What Is a Germicidal UV Light System?

UV air purifiers function based on a technology called Ultra Violet Germicidal Irradiation (UVGI). 

For decades, UVGI has been deployed in factories and hospitals where thorough sanitization is a necessity. 

As a matter of fact, the Center for Disease Control and Prevention (CDC), recommended UV light as a hospital infectious control method. The only difference between the UVGI products used in the hospital vs. the UV-light air purifier sitting in your home is the minimized size, and it is optimized for portability, easy use, and safety. 

This shows that a UV air purifier works if it is manufactured appropriately for both commercial and residential use.

How Does a UV Air Cleaner Work

Dr. Bryan Stone, MD, Internal Medicine and Nephrology, Chief of Medicine Emeritus for Desert Regional Medical Center, and a member of Vystar Corporation’s Board of Directors has said:

“It’s time to look more seriously at UV-C light air purification to help protect against airborne pathogens such as COVID-19, influenza, and pneumonia.” 

With a slew of medical authorities, such as Dr. Stone, stepping out to display their vote of confidence, putting their reputation on the line, we can trust that the viability of UV-light air purifiers leans significantly in a positive direction.

How Can You Differentiate Between Air Purifications Systems?

How do you differentiate between air purifiers with UV light like HEPA and ozone air purifiers? 

HEPA air purifiers can only filter particles that are as small as 0.3 microns in diameter. As a point of reference, your eyes can only detect particles as small as roughly 50 microns.  

In contrast, UV lamps in UV-C light air sanitizers are able to mitigate smaller pollutants.

Therefore, adding a UV purification system to a HEPA air filter (like the CleanAir Tower does) offers occupants a dual layer of protection. The purifier can filter small particles using the mechanical filter and destroy pathogens with UV light. 

What About Ozone Air Purifiers? 

The last thing you want is for your air purifiers to produce any side effect for health that outweighs any health benefits they may bring. This is the risk you run when you select ozone air purifiers that rely solely on ionization technology. 

This is because the chemical process of ionization tends to release ozone, which is a colorless toxic gas with a pungent odor. Once it’s inhaled, it may worsen respiratory health, especially in people with pre-existing respiratory conditions. 

CleanAir Tower: The Top UV-C Air Purifier

CleanAir Tower is unique in its own right because it does not rely solely on any particular air filtering process. Using a multi-pronged filtration system, which combines UV lamps, HEPA filters, MERV and bi-polar ionization, it comprehensively destroys airborne pathogens efficiently.

Moreover, the best part about it is that, following its approval by authorities, it is officially stamped “Certified Ozone-Free Technology” (UL 2998), indicating no adverse effects on human health. 

The device has been constructed with durability in mind, incorporating a steel frame with a powder-coated finish and several safety features, including a tip-over sensor. 

Finishing touches include soft rubber rolling casters that offer portability while protecting the most delicate flooring surface. You may also choose from a range of colors to match your interior design.
