Sitting in front of a fan you can’t help but notice the noise. Noise is generally made by the blades cutting through the air. Bladeless fans solve the problem of noise, and some even claim to create better air than your standard fan. The bladeless design also allows for a more evenly distributed airflow as it doesn’t have any blades that can trap air inside the unit, unlike conventional fans.

Why do fans make noise?
Let look a little deeper at how noise is created by a fan with blades. As the blades cut through the air, a small amount of air can be trapped inside the fan. The trapped air creates a low-frequency vibration that continues outside the unit. Though it may not seem like it, this vibration is actually a source of noise resonance that is always present in bladed fans.
You may also, depending on the fan, get a little noise from the fan blade motor as it turns. However, the majority of the noise is created by the blades cutting through the air.
Are bladeless fans quieter?
Bladeless fans are quieter than conventional bladed fans. Today’s generation of Dyson bladeless fans are reported to be 75% quieter than the previous generations which indicates a focus on making bladeless fans much more quiet moving forward.
So, let’s compare bladeless fans to conventional bladed fans and see if they really are quieter. On the surface, this sounds like a pretty objective topic, but it really depends on what you are comparing them with.
For starters, a typical bladeless fan is quieter than a standard bladed fan, but it is not entirely clear how much of that reduction in noise is from the lack of blades, and how much comes from other design features.
A typical bladed fan produces a noise ranging from around 60 dBA to 70 dBA depending on the fan.
A bladeless fan typically produces a noise of around 35 dBA which is significantly quieter than a typical bladed fan.
Since there is no sound produced by the blade, it is difficult to tell how much of the reduction in noise comes from the lack of blades and how much comes from other design features, and it remains to be seen if further developments will improve this understanding.
Being able to adjust the air speed/air flow on bladeless fans also can help with noise levels. When you want the fan to be quieter then set the speed to a lower setting. This makes bladeless fans an ideal bedroom fan.
Is the airflow better with fanless fans?
From my experience, I would say that the airflow from a bladeless fan is better than a regular fan. Doing some research you will generally find that it is said that air flowing from a regular fan feels a little choppy. This is because the fans chop the air as they turn. With a bladeless fan, air flows more smoothly.
Also, there are designs that give the air a better direction than fans do. These fans generally bring the air down on a point instead of chopping it up into many smaller streams of air that feed the room in a haphazard way. What this feels like from a bladeless fan is a consistent breeze.
Types of the bladeless fan
There are a few different types of fans available, but for this article let’s consider the bladeless desk fan and the bladeless tower fan.
The desk fan can be placed on your desktop. Some people don’t use the desks in their offices for anything but holding the computer. They decide to place the desk fan beside their computer for air circulation. This is a great way to keep your work area cool and comfortable and also helps prevent the heating up of your computer. The desk fan tends to have a hoop shape where the air flows from (though there can be variations on this).
Another option available is the tower fan bladeless which is used to create cooling at large distances from a standing position as opposed to one that can be placed on a table or desk. These fan units tend to be much bigger than the desk fan as they are designed to cool a much larger area.
The tower fan bladeless will usually have a base unit that houses the fan. Above this, there will be a column that is wider than the base unit. They tend to be oval in shape and larger in height giving more area for the air to blow from. These work well in a sitting room as the airflow will cover greater height – for example, all of the height of someone sitting on a sofa.
There are a number of advantages to using bladeless fans throughout your home or office environment. They create less noise disturbance than traditional electric or battery-powered appliances, typically last longer, provide lower operating costs and improve fuel efficiency.
Newer models have come to the market offering HEPA filters to clean the air that the fan blows out. Dyson also has a new model that both purifies and humidifies. These new generations of Dyson bladeless fans automatically sense and capture allergens and pollutants and display air quality in real-time.
Dyson fans in particular use the air multiplier design to improve and increase the airflow giving more air blown towards you. Ever since Dyson produced their bladeless fan, many other companies have produced fans similar in design. This shows that they are popular and people like the way they work.
If you are looking for a bladeless fan be sure to do your research. While it may seem all bladeless fans are alike, small differences can make a big difference in the quality of the product.
Airflow and noise levels variations, as well as design preferences all, play a role in determining which model is right for you. It’s not just about cooling air, it’s about purifying and ensuring the best quality air is used to cool you down.
