How To Choose The Delta Bath Fan CFM?

Delta has a wide range of bathroom exhaust fans on the markets for small to large sized bathrooms with fan speeds ranging from 50-cfm and all the way up to 130-cfm.

CFM stands for cubic feet per minute and it is a measurement of how strong the bathroom fan will exhaust air.

The recommended method to picking the right CFM for your bathroom is to have the CFM at least match your bathroom square footage if it is 100-sf or less.  For example, if your bathroom is 75 square feet --- then you want a CFM that is at least 75-CFM.

However, if you have a larger bathroom that is more than 100-sf, the best method is to add up the number of plumbing fixtures. You can read my full guide on choosing the right CFM for your bathroom fan here.

DC Brushless Motors

Virtually all of the Delta bathroom fans have DC brushless motors which makes them very energy efficient.

Many of these Delta fans are also Energy Star qualified. And since they run so efficiently, they also tend to be much quieter than the competition.

My top picks for Delta bathroom fans have sone ratings (measurement of loudness) from less then 0.3 to 2 sones. Anything less than 1 sone is virtually silent.

Humidity Sensors

Delta Electronics has bathroom fans with a wide variety of features such humidity sensors. A humidity sensor will detect rising moisture in your bathroom and automatically turn it on.

And when the moisture level drops below its target, it will automatically turn the bath fan off. You can also manually turn the bath fan on or off by toggling the wall switch.

This humidity control feature is great for home occupants who neglect to use the bathroom fan, or if you just don't want to fuss with turning the fan on.

Bath Fan Heaters

Delta also makes bathroom fans that have heaters.

The 1000+ watt heating element will blow warm air throughout your bathroom which is nice on those cold winter mornings. With these bathroom fans and heaters, a dedicated circuit back to the panel box is usually required.
