Should You Add a UV Air Sanitizer to Your Home?

Many people are currently looking for better ways to sanitize the air in their homes. There’s not much you can do about the air outside, but you can protect your family by making sure the air inside is clean and sanitized. So, do UV air sanitizers really work for indoor air quality? The answer is yes, they do.

However, in order to figure out if they’re right for you, you need to learn a little bit about them. You’ll discover where in the home they’re most effective, and how they work to sanitize the air you breathe. Plus, you’ll learn about the installation process and how to make sure you get the best air sanitizer possible.

What Is a UV Air Sanitizer?

what is

Simply put, a UV air sanitizer is an air purifier that uses UV light to eliminate airborne diseases, viruses, bacteria, fungus, and other microbiological organisms.

You can get a stand-alone UV air sanitizer to place in your home, or you can get one that attaches to your AC system in order to aid in making the air in your home as safe as possible.

Air sanitizers that use UV light are not replacements for your current AC system. In fact, they’re best used in conjunction with your system. Now that you know what they are, you may be wondering how they work.

How Does a UV Air Sanitizer Work?

When air passes through a UV air sanitizer, the lights in the machine emit UV-C light or ultraviolet germicidal radiation. This light is at a specific wavelength that serves to kill up to 99.9% of germs and harmful airborne particles. Some UV air sanitizers have been known to emit ozone, which is a health hazard. But, since the technology has advanced, it’s easy to find an air sanitizer that will not emit ozone.

how It works

UV-C light isn’t a new discovery. It has been used by humans for almost a century, and is naturally occurring but usually filtered out by the atmosphere. In fact, many hospitals use UV-C light to sanitize medical tools, operating rooms, and other sensitive equipment.

A quality UV air sanitizer, when installed properly, can do wonders for your air. They can be especially helpful to those with allergies, sensitive lungs, medical conditions, and people prone to sickness. When deciding on a UV air sanitizer, make sure to purchase one that has been tested by EPA-certified, third party labs. There are some sanitizers out there that claim to do the job but do not come close to getting 99.9% of germs out of the air.

Installation and Use


Finding the right UV air sanitizer can be more difficult than you may think. It’s best to consult an HVAC technician to determine which sanitizer will work best for your home.

Once you decide on one, it’s imperative that you have a professional install it. Since it works in conjunction with your HVAC system along with the air filter, it’s important that you have the proper setup in place.

After all, the air needs to be circulated through the UV air sanitizer to work properly. This is why they’re usually installed in the ductwork or directly in the air handler.
