Molekule vs Dyson: Which Air Purifier To Buy?

Updated: Mar 28, 2024

Both manufacturers produce premium purifiers that not only perform well but also look good. The Dyson models tend to be bladeless while the Molekule purifiers look kind of like the other purifiers but much more modern. The Moleko also uses a different filtration technology which we will talk more about later.

Molekule has fewer models available to buy than Dyson. It currently offers one model while Dyson has a wide variety of models and we talked about the differences between them earlier.

The Molekule is built with aluminum and has a sleek and stylish look. It is well built and has an average size. On top of it, there is a touch screen that allows choosing between modes, monitoring filters, and putting the purifier on stand-by.

With Dyson, you can see that there are four different designs: a portable one, a medium size, a tall one, and a smaller one. The medium (HP04) can create cool and hot air and also purify. The TP (a tall one) can create cool air and also purify, it has a tall tower design. The DP is a portable purifier, it also creates cool air and purifies, can be used on a desk, or for small areas. The cheapest and smallest one BP, it also creates cool air and purifies, and can be used for small areas.

All of them use a HEPA filter and some models also include a carbon filter. Other features may vary from model to model, you can learn more in our Dyson purifier comparison chart

Let's focus on the TP04 which is the tallest one. All of Dyson's purifiers have a bladeless design.

Dyson purifiers are bladeless and safe for kids and pets

Molekule vs. Dyson: size comparison

  Tall Wide Pounds
Molekule (in) 23 8.25 18
Dyson (in) 41.5 8.8 10.9

The Molekule is heavier but the Dyson is taller.

The Molekule has 4 modes: auto, dark, silent, boost.

  1. The auto mode is the most efficient. It automatically adjusts aiflow when air quality is bad.
  2. Dark mode is good for nights, it disables lights and dims screens.
  3. Boost mode is great for large areas, it cleans the air faster than any other mode.
  4. In silent mode, the machine is on low settings and makes around 30 dB.

The Dyson has a number of different adjustable settings. It includes airflow level, acceleration, auto mode, airflow direction, and night mode. 

Airflow changes the level push to the filter. There are 10 levels. Acceleration can be on or off and tend to go to 360 degrees if needed. 

Airflow direction can be either forward or backward which is a nice option if you want a purification on but don't want the fan blowing on you. 


Setup on both of them is easy. The Molekule starts by plugging it in, then you select a room size, and which mode needs to be on. The machine will take about 15 minutes to clean to understand which mode it needs to clean to purify the air the most efficiently. (calibration) When it's done calibrating, you can choose the mode. You can also connect the unit to your phone and choose the mode from there.

With the Dyson you need to plug it in, press the power button, and choose the settings you want by using the remote or your phone.

Both devices can be connected to the app but the Dyson also comes with a magnetic remote controller that can be attached to the machine.

Air purifier technology

The biggest differences in air purifiers technology: PECO (Photo Electrochemical Oxidation) vs. HEPA (+carbon) filtration. 

PECO uses light filtration to destroy particulars and allergens. It also has a pre-filter on the base of the unit.

Dyson filters work by passing air into the filters which trap the debris within the filters.

Maintainance & Cost per year

The Molekule has two main filters that should be changed in about 3-6 months and it will cost you around $130 a year.

Dyson has two filters: carbon and HEPA. Some models have only HEPA. The Carbon filter should be changed once per year. Dyson does not mention how often you should change a HEPA filter, we would recommend doing it once in six months. Changing the filters would cost 70 dollars a year but if you have a Dyson with HEPA only, it will save you some money.
