Green and clean. After Wednesday's Good Question on plug-in air fresheners, we thought we'd revisit this post on a light bulb that also cleans the air. Our friends over at Treehugger, pointed us to some compact fluorescent lightbulbs that are not only earth-friendly, but also smell-friendly. Fresh2 lightbulbs not only save energy, but are coated with titanium dioxide that helps remove odors when the lightbulb is turned on. We'll spare you a science lesson, but when light hits the coating it sends ions out into the air that attach to the odors floating around. posted originally from: AT:Hometech The manufacturer touts this as a great alternative to chemically-based air fresheners. At the cost of $10 per bulb, it may seem a bit pricey. However, after you consider you're getting two products in one, it softens the blow. We think using these in our homes would please both our moms and mother earth. Available here.
