Does a Dyson Fan Actually Cool the Air?

If you ask yourself whether a Dyson fan cools the air, the short answer is no. A Dyson fan won’t cool the air. Like regular fans, it makes you feel cool by causing the sweat on your body to evaporate faster. The evaporation of sweat is what makes you feel cool, and Dyson fans are excellent for that. But they don’t lower the air temperature like an air conditioner would.

Introduced into the market in October 2009 by James Dyson’s consumer electronics company, the Dyson fan has a unique characteristic: no exposed blades. They called it the Dyson Air Multiplier because it increases airflow in your room, creating the cooling effect you feel if you are in front of it.

The company has since expanded the range of Dyson fans and increased capabilities to include air purifying and heating. Air purification or filtration removes particulates from the air to make it cleaner and healthier to breathe.

Particulates include dust particles, allergens, car exhaust fumes, and combustion fumes. The fan’s heating function relies on the Dyson patented air multiplier technology to amplify the hot air the device creates.

If you are interested in the technology behind the Dyson fan, this article is for you. I will explore how the bladeless technology works, the durability of Dyson fans, and the pros and cons. I will also compare its performance against an air conditioner and a regular fan with blades. As usual, I will answer some common questions about Dyson fans at the end of this article.

How well does a Dyson fan perform?

Simply put, Dyson fans perform just as well as regular fans. Now that may not sound like a good pitch for a device that co

Despite being called a “bladeless” fan, the Dyson fan has rotating blades hidden inside the pedestal.

There’s an electronic element and a few scientific principles at play. The pedestal of the fan contains a brushless electric motor that takes in air and feeds it into the circular tube. The motor rotates nine asymmetrically aligned blades to pull air into the device. Air flows along the inside of the fan until it reaches a slit inside the tube. This provides the airflow that creates the breeze of cool air you feel in front of the fan.

Through a process known as “inducement,” air flows through the slits in the circular tube and out through the front of the fan, also pulling air from behind the fan.

Obeying the laws of physics, the air surrounding the periphery of the fan also begins to flow in the direction of the breeze. This process is called “entrainment.” 

According to Dyson, the newest iterations can project more than 77 gallons of air per second. Dyson fans increase airflow output up to 16 times the air drawn into the motor through these processes of inducement and entrainment.

As a consumer, you need to be mindful of a couple of things here. If all you want is a quick fix for the heat of the summer, you don’t have to get a Dyson fan. While these devices do a pretty good job keeping you cool, they don’t necessarily do it any better than regular fans would, one that comes at a fraction of the price.

Another thing worth exploring when you’re discussing any fan, is the noise it produces. Most fans produce a lot of annoying noise, especially at higher settings—the creators of this fan claim that it is quieter than your typical fan. And at the lower settings, the Dyson fan is pretty much silent, but as you speed it up, it gets louder. At its loudest, it is still quieter than your average fan, but it is no longer silent.

Dyson fans, however, aren’t just “cool looking” gizmos. Other than their “cool” features like WiFi connectivity, air filtration/purification, etc., they also come with a much sturdier build quality than regular fans. So a Dyson fan will probably last you much longer.

How Does A Dyson Fan Heat The Room?

Newer models of the Dyson fan, like the Dyson Pure Hot+Cool™ HP01, have heating and air purifying capabilities. The heating function uses air multiplier technology to ensure uniformity of temperature in the room.

Inspired by technologies found in turbochargers and jet engines, scientists at Dyson created a fan that utilizes positive temperature coefficient heating plates that heat up quickly and efficiently without disrupting airflow.

The material used – Acrylonitrile butadiene styrene – means the heater is also cool to the touch, while it will automatically switch off if knocked over.

Noise Reduction

A challenge that the Dyson engineers faced with the original Dyson air multiplier was noise. 

They solved the challenge by creating a feature called the Helmholtz cavity. It’s a little hole where the motor and impeller sit. By adding Helmholtz cavities into the base of the Air Multiplier, engineers increased air pressure, and ultimately these cavities began to work as silencers.

According to the fan’s manufacturer,  the breeze generated by these devices is more consistent and steadier than one from a standard fan with blades.

Some more expensive models also have a built-in air treatment system, acting as an air purifier. This can be a useful feature if you’re living with asthma and allergies. Dyson claims that its air purifiers can catch pollutants as tiny as 0.3 microns and remove up to 99.97% of allergens from the air.

Dyson fans come in three types: desk, tower, and pedestal. While most are designed for cooling, some, like the Dyson AM09 and the Dyson HP02, have both a cooling and a heating mode.

In addition to the unique design of Dyson fans, they also have modern, ‘nice-to-have’ extras like Wi-Fi connectivity and compatibility with your voice assistant. 

How Durable Is A Dyson Fan?

According to the engineers at Dyson, their fans are stronger than others. They come with a steadier build than your regular fan. Due to its unique design, the center of gravity is low, making tilt in any direction easier.

Dyson Fan Pros and Cons

Now that we have discussed the Dyson fan and its technology, here are its pros and cons.

The Pros

  • Sleek and unique design is appealing to the eye.
  • Provides a steady and consistent supply of cool air.
  • 60 percent quieter than conventional fans.
  • Use less power than an air conditioner.
  • Safer and easier to clean since there are no exposed blades.

The cons

  • It’s more expensive: if you just want to cool your room, you can buy a product that does the same job at a lower price.
  • Noisy when set on maximum power.
  • Does not cool the air- Dyson fans create the wind chill effect.
  •  It only works if you are directly in front of it.

Dyson Fan Vs. Rotation Blade Fans

What sets the Dyson fan apart from the regular fan? The Dyson fan doesn’t have the disadvantage of a fan blade that buffets air in irregular bursts toward you as the blades rotate. 

The airflow you will get from the Dyson is the same as that from a fan with blades. However, the airflow from the Dyson is a smooth breeze rather than the turbulent buffeting flow you get from the blades, which can be uncomfortable.

Dyson Fan Vs. Air Conditioning

The Dyson fan is much greener than air-conditioning. It uses 40 watts compared to 50 to 2500 watts. Unlike air-conditioning, the Dyson fan does not contribute to sick building syndrome since it increases airflow in the room.

However, when it comes to cooling your room, air conditioning does better than any Dyson fan.

The Dyson Fan Price

The Dyson fan might not be for you if you want a cool breeze in your home on a limited budget. Some of the Dyson fan models cost $500.The more features the fan has, the higher the price. 

In contrast, how much does a regular fan cost? A decent one will be yours for as little as $54.

So, if you’re looking to invest in a quick cooling fix, the Dyson fan is worth considering. Despite all its features and qualities, Dyson fans sell for their “cool” look.


There is no doubt the Dyson fan introduced new technology in the air cooling industry with its blade-less air multiplier. With a sleek design and lower power consumption, the Dyson fan is set to be among the top fan brands of the future.

Dyson has created a fan compatible with 21st-century technology like wifi and home voice assistant, making it easy to operate.

The added functions of air purifying and heating set the Dyson fan in a class of its own. For cooling, the Dyson fan performs just as well as a fan with blades.
