What Is An Ultraviolet Air Purifier? (And Do They Work?)

With the ongoing COVID-19 pandemic, many area homeowners and business owners are looking at more advanced ways of keeping their homes and businesses safe from airborne pathogens.

One of those advanced methods of air purification many are now researching are ultraviolet light (UV) air purification.

UV light air purifying technology has been around for some time now, but with the recent uptick in questions involving this technology below is a quick rundown of how it works, the pros and cons of using UV light air purification and a highly recommended model for Lowcountry residents.


How UV Air Purifiers Work

As the name suggests, ultraviolet air purifiers use ultraviolet light to damage the DNA of airborne pathogens like bacteria, viruses and mold — causing them to self-destruct, making them harmless.

This is a similar process that occurs when you get a sunburn at the beach. UV light from the sun damages the DNA in your skin cells, which causes redness and swelling.

When installed in your heating, ventilating and cooling system’s ductwork, air is forced through the UV air purifier before being pushed into your home or business, thus purifying nearly every cubic inch of air that passes through your system and helping reduce those airborne pathogens.


Pros & Cons Of UV Air Purifiers

The biggest advantage of installing a UV air purifier has to be the ability to reduce and/or help eliminate different airborne contaminants, simply by installing one in your home’s HVAC system. While your home’s built-in air filtration can help eliminate things like dust and other larger particles, working together with an ultraviolet purifier adds that extra layer of protection that many homeowners are now seeking.

One cause for concern with UV air purifiers is that they can produce ozone, which is harmful for humans when exposed to high levels.

Many UV air purifier manufacturers have accounted for this ozone production by improving technology using various methods to reduce — and as you’ll see below — nearly eliminate any ozone production.


What Is The Best UV Air Purifier?

A few weeks ago we reviewed some general air purifying basics, and included brief description of the HALO-LED Whole Home In-Duct Air Purifier, which still stands as one of the most requested air purifiers we currently install.

The biggest reason for this being the HALO-LED’s highly effective air purifying, UV technology — that is both mercury-free (many other UV light purifiers use mercury lamps to produce UV light) and is zero ozone compliant. This means that you can get some of the highest level of air purifying technology without any of the usual byproducts produced by many other air purifiers.

We sincerely hope that you stay safe and healthy for as long as this pandemic lasts, but if you have any questions about air purification for your home or business in Charleston, feel free to contact us today.
