UV vs Negative Ion For Air Purifiers? - What's The Difference?

Sterra Admin

According to a study of the World Health Organization, 9 out of 10 people breathe polluted air. What is more alarming is that 7 million people every year die because of the harmful effects of ambient and household air pollution. 

Even if your home looks clean, it is most likely filled with smoke and smog coming from cars and toxic factories. The air in your homes is not safe. From harmful chemicals to airborne viruses and bacteria, these air pollutants are present in almost every household. This is why many people are buying air purifiers. Today, the latest and most powerful air purifiers are equipped with either UV and Negative Ion features, but which one is better? 

 

What is the difference between UV and Negative ION on air purifiers?

UV or Ultraviolet is a feature in the better air purifiers along with the HEPA or High-Efficiency Particulate Absorbing filters. The UV-C light wavelength used in most air purifiers range from 100 to 280 nm, which has the shortest wavelength and transmits the most energy. This is what makes it so powerful that it fully eradicates airborne pathogens and microorganisms like mold, bacteria, viruses and other tiny harmful microbes in the air. UV is also used for germicidal use in hospitals to improve indoor air quality for residential HVAC systems.

Negative Ion on the other hand work by creating negative ions using electricity and then releasing them into the air. These negative ions attract particles in the room, such as dust, bacteria, pollen, smoke, and other allergens. This creates a charged particle that is eventually cycled back to the ionizer where it is filtered.

 

Which is better - UV or Negative Ion? 

The UV light purifier is by far the superior solution. UV Light is a newer and cleaner technology. It works to eliminate harmful air particles, rather than just contain them. UV also eliminates harmful particles at a much faster rate, generally in seconds, as compared to over an hour for Negative Ion. This is also why UV is the first choice in eliminating viruses in the pandemic.
