Sometimes it is not the difficulty of the journey but the rock in the shoe that makes the biggest difference. I like this saying as it shows that sometimes changing the small things can make life easier. While changing a bathroom fan is nothing to boast about, we did recently replace our old dusty fan from the 80's in our bathroom with Broan Ultra-Green Single Speed Fan.
We did a little before and after and found this one to be so much more quieter and more efficient, and of course much less dusty. This is one of the quieter fans you can buy and it performs very well, plus its more energy efficient and therefore not only better for the environment but also better for our pocket books. While no one will be able to tell we made this small change, to us its great since we wont feel like we are blasting off into space every time we enter the bathroom.
