Query: loud fan

I bought one of these from the local Lowe's and returned it. The fan in it was loud even on the lowest setting. This would have been fine if it were moving a lot of air, but as the others on here have said it barely moves air.. so why all the noise? It was louder than my computer.Also, it doesn't need to move a lot of air through it to treat all of the air in a room over the course of 24hrs.I'll try another at some point.. and if it's loud then I'll swap the fan for a higher quality one.
