Have you ever used a UV light filter before? If you haven’t you should really give them a try. They are as good as HEPA filters. The differences between his head and how a UV light filter works compared to a HEPA filter. For example, a HEPA filter is designed with many tight fibers that can catch the smallest pieces of debris and bacteria. This is how a HEPA filter keeps the indoor air clean, for comparison a UV light filter works to keep the indoor air quality in good condition by killing all germs and bacteria on contact. The only thing you have to worry about with a UV light filter is that with a UV light filter you have to worry about changing the bulbs so you’re going to want to check your bulb to make sure that it hasn’t burned out every now and then. The UV light filter is very simple and effective. The way UV light filter works is by simply attaching to your heating and air conditioning system, and once it successfully attached to your heating and cooling system it should be helping to give you good indoor air quality for quite some time. I used to use HEPA filters but recently I’ve switched to UV light filters because in my opinion I have found them to be superior. As long as I check on the bulb every now and then to make sure that it’s still is working correctly then there isn’t it isn’t much for me to worry about, and I haven’t found that I have to change out the ball this way less frequently than I was having to change out the HEPA filters.
