UV Purifiers Make for Cleaner Air

Summers mean muggy air and lots of germs, with everything from mold spores to bacteria and germs floating around just waiting to make our lives miserable. Each unwelcome invader can enter a home extremely easily and remain trapped there for some time. We rarely open our doors and window during the hotter months, after all, which means that germs and mold spores can circulate throughout your home without any way to escape.

The best solution to such problems is a UV air purifier installed into the home’s HVAC system. It can help sterilize the air in the house and provides strong protection against germs and other biological contaminants. Here’s a quick breakdown of how it works.


Ultraviolet light, or UV light, is the secret weapon the purifier uses to kill germs. If you recall from science classes in school, UV light can’t be perceived by the human eye, but it can be found in copious amounts in sunlight. (It’s what causes our skin to tan and burn in the sun.) UV lights radiate the same light in reduced amounts, keeping it safe for human beings and pets. Indeed, you can see its effects at amusement parks and concerts: they make white clothes glow in the dark (an effect of the UV light interacting with the chemicals in your laundry detergent).

Those lights may be safe for us, but they’re lethal for germs and bacteria, either killing them instantly or fusing their DNA, which renders them unable to replicate. Either way, it spells bad news for them and good news for your home. The next question becomes where to place such a light in your house where it can do the most good.


When your air conditioner runs in the summer or your heater in the winter, it circulates the air in your home, cycling it through the system and into the ducts gradually. That makes it an excellent way to “scrub” the air in your home without having to use a lot of space. The UV lights are set up at the apex of the ducts: shining an impenetrable web across the width of the ducts so that all the air passes through the light as the system runs.

This means you help keep your air clean and free of germs every time you run the AC (or the heater in the winter). Not only does it make for a healthier household, but it helps improve your air conditioner’s efficiency since you don’t need to open the windows or air out the house in order to “air out” the home. UV air purifiers use few moving parts and require only the periodic replacement of the light bulbs: giving you good value for the money and ensuring that your family is happier and healthier for many years to come!
