This is how you know you need a new UV3 Bulb
The Bulb finally went from Blue to Orange 3 weeks ago (Dec. 2018). Meaning that its time to replace the bulb and the longevity of the bulb surprised us both. We initially bought our GG1000 over 4 years ago to to reduce the odor from our cat litter 6 years ago when we had a 1 story 1300 sq ft home and to reduce the car exhaust fumes since we used to live on a very corner property that is a main thorough fair boulevard . 2 years ago We moved to a larger 3400 sq ft. and placed this in the hallway also to control the cat litter odor (and to use a night light as well). Believe it or not this has helped tremendously. This is a great product. IF you buy this product put in areas that is prone to germs where it can travel. Near staircases, in between hallways connecting bedrooms, bathrooms or family/living rooms.<br /><br />There is minimal maintenance so long you do an occasional dusting of the air vents top and bottom maybe 3-6 months but that is it. You'd forget it's there
