Review on GermGuardian AC4100 Sanitizer Allergens Guardian by Leandro Gray

My bedroom feels and smells better since I installed it. I run day and night I have to buy a few more. I have another air purifier in my room but it didn't do the job as well as this one. Update June 2017: I've been using this air purifier in my bedroom for about a year. At first the blue light only lasted about a month, then it went out. I bought a new light that never worked, very weak wiring and very complicated installation. A few days ago I was sleeping when I heard this weird high pitched noise waking me up. Then he started smelling smoke. It was an air purifier, it smelled of burning. Thank God I was home, or who knows, my whole house could have burned down. I must say that I have had many other less expensive air purifiers that have been in daily use for many years. This one took about 1 and cost 2 times more than the others. It worked well with UV light for the first month, but then it was just a regular air purifier. I will never buy one of these again. Back to the cheaper and much more efficient air purifiers I have at home. Unfortunately I recently bought a larger version of GermGuardian, I hope it doesn't burn through either. I guess I'll have to make sure it's off when I leave the house. I don't want my furry babies to die in a fire.
