The bulbs continue emitting the same amount of visible light even when they have lost their air purification potential
I think that weather conditions change is slowly affecting the habitat & natural environment in the section in which I live. I guess that we’ve typically had airborne flu symptom irritants in high volume, especially while I was in pollen season. My up-to-date home is in the south near the Gulf Coast, so the weather is boiling & humid for much of the year. Obviously mold has typically been a problem in this kind of weather conditions, but I’m starting to think bacterial colonies are growing in higher numbers outdoors with the warmer & wetter weather. In the middle of the night when humidity is at its highest, parts of our town odor horrible. Small ponds have turned into red cesspools of disgusting organic growth. I have developed lung irritations to all of this mold & bacteria & I felt care about nothing was laboring. Short of being on steroids all of the time, I wasn’t sure what I should do about the mold & bacteria exposure. My HVAC company told me about UV light whole-house air purifiers & how they destroy mold spores & bacteria on contact. You can even buy the UV bulbs & have them installed inside your air handler so it adds a layer of air purification and your HVAC filter. These UV bulbs also prevent microbial growth inside the a/c. However, they quit laboring after 10-12 weeks, but you won’t guess when it happens. The bulbs continue emitting the same amount of visible light even when they have lost their air purification potential. That’s why I have up-to-date bulbs installed every several to nine weeks to be safe. I don’t want to randomly lose the effects from our UV bulbs because I waited too long for substitutements.
