It's great to know that the bulbs work on the odour, this is a good testimonial, thanks for sharing it here with everyone. We have a problem in our house, that is the bathroom fan on the main floor does not suck out the bad air fast enough so quite a few times, we need to keep the fan on after we are "done" using the bathroom. Problem is, we quite a few times forgot to turn the fan off and went to bed and so the fan runs all night throwing out the heat of the house for nothing and so the furnace keeps working overtime to keep up with the temperature in the house and this means more gas being used = more money out of the window. Now with this testimonial, we can't wait to bring some bulbs like this into our house, unfortunately they are not available in Canada yet.
