The Holmes Twin Window Fan is a powerful fan that operates quietly and amounts to nothing more than pleasant background noise if customer reviews are to be believed. And you’ll have to believe them, because there’s no dB rating to tell you otherwise. Check out our best window fan list for more great fans!

Why We Like It – Holmes Window Fan

Unlike the Holmes Lil Blizzard Oscillating table fan, the Holmes Window Fan is a two-speed setting fan that fits most double-hung and slider windows as long as those windows are 25 inches wide and 12 inches high at minimum. And though it’s recommended to use a screen, the motor is water-resistant as an extra layer of protection.

  • Lightweight
  • Excellent Customer Reviews for Quietness
  • One Touch Adjustable Thermostat
  • Only Two Speeds
  • No dB Ratings


The Holmes Window Fan has two speed settings, unlike the Bionaire Window Fan. It has dual blade operation, and independently electronically reversible motors to allow for air intake, exhaust, and air exchange. We appreciate the motors for their ability to pull out hot air and push in cool air, but the two speeds are a little unfortunate. Check out our other recommendations including our reviews of the SailFlo LFW-25, Comfort Zone CZ310R, and the Lasko Fan.


The Holmes Window Fan is designed to fit most double-hung and slider windows. It’s recommended to fit windows 25 inches wide and 12 inches high minimum. This Holmes fan comes with an adjustable extender screen and an adjustable panel for a better, more secure fit on your window. And like the Genesis A1, the Holmes Window Fan is relatively lightweight, coming in at just short of eight pounds.

Noise/Sound Level

The Holmes Window Fan claims to operate quietly, and we really have no reason to doubt them. Still, we wish they would have provided some dB levels, like with portable fans and some great desk fans, just as proof and for accurate measurements. But going off customer reviews, the fan is indeed quiet, amounting to not much more than pleasing background noise.

Versatility/Modern Features

The Holmes Window Fan is built with a water-resistant motor so your fan won’t fail on you if there’s some rain outside. It also comes equipped with a one-touch thermostat. This allows you to set and control your fan speed and temperature throughout the day so you’re always achieving optimal airflow


The Holmes Window Fan is energy-efficient and uses up to 60% less energy. So not only will you be saving on energy costs, you’ll be helping to reduce your carbon footprint too. There’s no assembly required, the same as its cousin the Holmes Fan, so all you have to do is take it out of the box and set it up in your window!

Holmes Window Fan Wrap Up

The Holmes Window Fan is a lightweight and assembly-free fan that still manages to both be powerful and quiet. It only has two speeds, unfortunately, but this is negated when you factor in the fan’s energy efficiency. Finally, the thermostat allows for control over fan speed and temperature at all times throughout the day!
