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.
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 pricy. 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.
