Our reviews are based on in-depth research and product analysis. Let's dive in!

  • High CFM rating for a 4” model
  • Small enough to be attached with a carbon filter on the ceiling


  • The clamps that come with the inline fan are poor quality
  • Not as a quiet as advertised

IPOWER 4″ Inch Inline Duct Fan Product Review

For a smaller model, at 4”, the IPOWER 4″ Inch Inline Duct Fan from IPOWER comes with a high CFM rating, at 190 CFM.

It works efficiently and blows air powerfully, despite being compact. The ventilation system is high-quality and also uses an IPOWER carbon filter.

Although this fan does claim to be quiet, due to its composite fan blades and center hub, it is arguably not as quiet as advertised.

These features should reduce the noise level and vibration, but some users have claimed that there is a loud buzzing sound when the fan is on a low power setting.

Quietness should be a priority if you need to be discreet, so bear this in mind when choosing the right fan for you.
