We manufacture several series, which can be bought here - http://usfanco.com/index.php/residential-fans/bath-fans.html, each with different features and CFMs [cubic feet per minute ratings], which might make the decision on which model to install a little confusing.
The Contractor Fan series are the smallest and least expensive.
Then we have the MS series where the sones (sound level) are a little lower/quieter. This series also comes in lighted versions.
The SH series fans are even quieter, and are also energy efficient. This series also comes in lighted models.
Below are a few examples in each series.
*The NXSH50 and NXSH80 are Energy Star Rated.
