I decided to switch to UV light filters recently. Even though UV light filters are not as enjoyable in my opinion as HEPA filters are, I got tired of typically having to change out the HEPA filters all the time. What I liked about the UV light filters was that they were out of sight and out of mind. With the UV light filter I never had to see them they just worked, the way they work is pretty amazing as well, you see a UV light filter works by killing all the germs on contact. If you are worried about having bad air quality you are never going to have to worry as long as you have a UV light filter, UV light filter will not let anything bad begin floating around in your air. No germs for bacteria, because the moment they come in contact with the UV light filter they are annihilated. Now the one drawback to having any UV light filter is you do not know when the bulb burns out. That was something that I liked about to keep the filters that you can certainly see what needs to be changed. With the UV light filter, you need to check on it sometimes to make sure that it hasn’t burned out. If you do not check on it often enough it can begin causing bad indoor air quality because the UV light filter is not working as it’s supposed to. Other than that you feel like a filter is a great option if you are looking for something other than a traditional air filter to keep your indoor air quality nice as well as clean.
