Low profile bathroom exhaust fans are the sleekest bathroom ventilation options on the market, with casings thinner than the traditional bathroom fan so that they are perfect for any project, from new construction to remodels. Here is what we found for the best low profile bathroom fans on the market.

1. Overall Best: Panasonic WhisperFit EZ

Panasonic FV-0811VF5 WhisperFit EZ Retrofit Ventilation Fan, 80 or 110 CFM

The best overall low profile bathroom exhaust fan on the market is the Panasonic WhisperFit EZ due to its combined features of affordability, quietness, and versatility. It boasts of a low-profile design fit for old-style 2″ by 6″ constructions.

This fan can adapt to different energy needs, allowing you to choose between the 80 or 110 CFM settings.

It also boasts of having a near-silent motor, having less than 0.5 sones at its 80 CFM setting, which is large enough for an 80 square foot bathroom. Bathroom ventilation fans are considered quiet below 1 sone and near-silent below 0.5 sones.

Pros

  • This fan is highly adaptable in its ability to switch between CFMs so that it can fit small or large spaces.
  • This fan is one of the most noiseless models available at just 0.3 sone at 80 CFM and 0.8 sone at 110 CFM.  
  • It has high value for its cost, which is lower than many competitors on the market.

Cons

  • This fan doesn’t come with a light. Panasonic makes a WhisperFit model with an LED light (amazon link), but we determined it to be a less cost effective option.
  • Installation may be difficult for some.
