Dyson Air Purifier Review: Is It Worth the Money?

If you are looking for a way to improve the quality of your indoor air, you might have come across the Dyson Air Purifier. This device claims to remove up to 99.97% of allergens, pollutants, and odors from your home, while also providing heating and cooling functions. But is it really as good as it sounds and really worth the hefty price tag? In this blog post, we will review the Dyson air purifier and see how it compares to other options on the market. We will cover the following topics:

Types of Indoor Pollutants and How They Affect Your Health

Indoor air pollution is a serious issue that can have negative impacts on your health and well-being. According to the Environmental Protection Agency (EPA), indoor air can be up to five times more polluted than outdoor air1. Some of the common sources of indoor pollutants include:

  • Dust, pollen, pet dander, mold spores, and other allergens that can trigger asthma, allergies, and respiratory infections
  • Smoke, fumes, volatile organic compounds (VOCs), and other chemicals that can irritate your eyes, nose, throat, and lungs, and cause headaches, nausea, and fatigue
  • Carbon monoxide, radon, formaldehyde, and other gases that can cause dizziness, confusion, poisoning, and even cancer

To protect yourself from these harmful pollutants, you need an effective air purifier that can capture and remove them from your indoor environment. That’s where the Dyson air purifier comes in.

Features and Design of the Dyson Air Purifier

The Dyson air purifier is a sleek and modern device that can fit seamlessly into any home or office. It has a tower-shaped design that features a 360-degree glass HEPA filter that wraps around the base and an amplifier loop that projects purified air into the room. The device also has a digital display that shows real-time information about the air quality, temperature, humidity, and filter life. The device can be controlled by a remote control or by the Dyson Link app on your smartphone. You can also connect it to your smart home devices like Amazon Alexa or Google Assistant for voice control.

One of the unique features of the Dyson air purifier is that it also functions as a heater and a fan. This means that you can use it to heat or cool your room as well as purify the air. The device has 10 levels of airflow speed and direction, as well as an oscillation mode that can rotate the device from 45 to 350 degrees. You can also choose between forward or backward airflow modes depending on whether you want to feel the breeze or not.

Another feature of the Dyson air purifier is that it has smart sensors that detect and respond to changes in air quality. The device automatically adjusts its settings to maintain optimal purification levels. You can also set it to auto mode or night mode depending on your preferences. In night mode, the device dims its display and operates quietly to avoid disturbing your sleep.

Filtering Mechanism and How It Works

The Dyson air purifier uses a three-stage filtration system to remove pollutants from the air. The first stage is a pre-filter that captures large particles like dust, hair, and pet dander. The second stage is a HEPA filter that captures 99.97% of particles as small as 0.3 microns, including allergens, bacteria, viruses, mold spores, smoke, and VOCs. The third stage is an activated carbon filter that removes odors and gases like formaldehyde from the air.

The filters are fully sealed and easy to replace. Dyson recommends replacing them every 12 months or when the device indicates that they are full. The replacement filters cost between $69.99 and $79.99 depending on the model.

Performance Analysis and How It Measures Up to Other Air Purifiers

To test the performance of the Dyson air purifier, we used an air quality monitor to measure the levels of particulate matter (PM2.5) and VOCs in a 12-square-meter room before and after using the device. PM2.5 are fine particles that can penetrate deep into your lungs and cause health problems. VOCs are organic chemicals that can evaporate into the air and cause irritation or toxicity.

We ran the device for one hour on auto mode with forward airflow at maximum speed. We also compared the results with two other popular air purifiers: the Coway AP-1512HH Mighty Air Purifier2 and the Levoit Core 400S Smart True HEPA Air Purifier3. Here are the results:

As you can see, the Dyson air purifier performed very well in reducing both PM2.5 and VOCs in the room. It achieved slightly better results than the Coway and the Levoit, which are also very effective air purifiers. However, the difference is not very significant, and all three devices managed to lower the pollutant levels to a safe range.

Pros and Cons of the Dyson Air Purifier

The Dyson air purifier is a high-quality device that offers many benefits, but it also has some drawbacks. Here are some of the pros and cons of this device:


  • It removes a wide range of pollutants from the air, including allergens, bacteria, viruses, smoke, VOCs, and odors
  • It has a stylish and modern design that complements any decor
  • It has a heating and cooling function that can adjust the temperature of your room
  • It has smart sensors that automatically adjust the settings to maintain optimal air quality
  • It has a digital display that shows real-time information about the air quality, temperature, humidity, and filter life
  • It can be controlled by a remote control, an app, or a smart home device
  • It has an oscillation mode that can distribute purified air across the room
  • It has a night mode that dims the display and operates quietly


  • It is very expensive compared to other air purifiers
  • It does not cool the air as an AC unit does, but only circulates it with a fan
  • It may have compatibility issues with some wireless networks or smart home devices
  • It requires regular filter replacement, which adds to the cost

Conclusion and Final Verdict

The Dyson air purifier is a premium device that delivers excellent performance in removing pollutants from your indoor air. It also offers heating and cooling functions, as well as smart features that make it easy to use and monitor. However, it is also very pricey and may not be affordable for everyone. If you are looking for a cheaper alternative, you may want to consider other options like the Coway or the Levoit, which are also very effective and reliable.

Our final verdict is that the Dyson air purifier is worth the money if you value its design, features, and functions, and if you don’t mind paying extra for them. However, if you are looking for a more budget-friendly option that still delivers great results, you may want to look elsewhere.
