Last year I added UV-C bulbs to my air conditioner system. One bulb is located before my air filter as well as the minute bulb is located after my coils in area leading to the opening to the entire duct plan for the house. The bulbs utilize a special ultraviolet light frequency that is so bright that it kills essentially anything that it comes in contact with at close enough proximity. They’re so bright you’d go blind if you stared at one straight for an minute. But for someone love myself with respected seasonal flu symptoms as well as bad enough asthma as it is, they’re amazing. I use the highest allergen rated air filter that my hardware store carries as well as I am thorough as well as frequent with my Heating, Ventilation, as well as A/C repair as well as repair appointments. I even have my ductwork professionally cleaned every many years. Despite all of these attempts at better air quality, I was still noticing issues with shortness of breath, headaches, as well as occasional wheezing as well as sinus congestion. My Heating, Ventilation, as well as A/C specialist advocated the UV-C bulbs at that point as well as I promptly busy an replacement appointment for the following week. The first month with the bulbs was love a dream, no headaches of any kind as well as I felt love I could breathe easier with little to no nasal or sinus congestion. They have been particularly the best investment in my plan yet, but after 8 months of use I started to notice a drop in performance. I had occasional headaches again as well as my lungs weren’t feeling as wonderful as usual. I assumed that the bulbs would burn out completely when they had expelled all of the ozone gas inside, but I was wrong. You could have those bulbs in their creating light for years after they have been used up completely for their antimicrobial properties. My Heating, Ventilation, as well as A/C tech put in new bulbs Last month and I have been living better again as a result.
