### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Price is good for the CFM
  

*by O***E on Reviewed in the United States on September 8, 2024*

The inlet and outlet was described as 4 inches, but the size was actually only 3 1/2" which created excessive misfit with a 4" flexible coupling when mounting.This size difference could cause leaking of the radon gases on the outlet side.
