Input:
I have been sleeping with a box fan in my bedroom  year round for many, many years and have owned several different models but this one tops them all. I can turn up my thermostat in the summer and still stay cool and comfy, in the winter it helps  circulate the warm air in the house. I have a teenage son at home and when he has friends who sleep over they can be a bit noisy sometimes. However, with my Lasko fan turned on the number 2 setting I don't hear them and my son's bedroom is right across the hall from mine. This being said, if you are looking for a quiet fan then I suggest you buy another brand. However, if you want to lower your electric bill and block out noise then this is the one to buy. You can't go wrong with this Lesko!! I reccomend it highly!
