Molekule vs. Dyson: Air Purifier Review & Comparison (2019)

Molekule and Dyson are well known high-end air purifiers. They perform excellently well, are easy to use, and are well built. 

Molekule uses the PECO filtration system which stands for Photo-Electrochemical Oxidation. This means that Molekule uses a light-based chemical reaction to destroy allergens such as dust particles, pollen, and spores. The smaller ones enter the PECO filter where it uses light to shine on a specially designed nano-particle filter and destroy the particles.

Dyson relies on HEPA filtration which stands for High Efficiency Particulate Air. This means that it uses a high-efficiency mesh filter to capture and hold airborne pollutants until the filter is replaced. HEPA filtration has been in existence since the 1940’s. It made its way into residential home filters in the 1950’s. It’s still the most widely used type of air purification on the market.

Dyson uses a large HEPA filter in addition to an activated carbon filter. The HEPA filter removes fine particulates while the activated carbon filter helps to remove the smells and gases.

PECO filtration destroys the particles instead of just trapping them which prevents them from growing more inside a dirty filter out otherwise contaminating the air as it passes through. However, it requires light to work correctly which could be a problem for people who are sensitive to light or prefer the looks of a dark air purifier

HEPA filtration is extremely reliable and still one of the most popular and effective methods of air filtration. It, however, cannot capture particles smaller than 0.3 microns which may include harmful allergens or airborne illnesses.

Both Molekule’s PECO and Dyson’s HEPA filters need proper maintenance to work effectively and both need to be replaced regularly. 

Both come with fairly basic parts and limited accessories. They focus their efforts on a great performing air purifier and leave out the rest. Molekule possesses a power cord, pre-filter, and PECO filter while Dyson possesses a power cord, HEPA filter, and activated carbon filter. All features of both easy to install and simple to replace.

The Operating Modes of Molekule include:

  • Auto Mode: You can input information about your room like the size to help the purifier determine the optimal fan speed and airflow for best results. This is a nice feature if you are not sure of the quality of your air and you want adjustment.
  • Boost Mode: The Molekule runs at the highest possible airflow setting. This mode is great for purifying spaces right after you dust or other cleaning cycles.
  • Silent Mode: When the purifier is in Silent Mode, the fans are running at the lowest possible sound outputs level of around 30 decibels
  • Dark Mode: It is mainly a reserve for purification while you sleep or other light-sensitive times. Keep in mind when the Molekule is in dark mode, it won’t be able to use PECO filter properly. Once the light is turned back on, it will treat the particles that were gathered when in dark mode.

The operating Modes on Dyson Air Purifier include;

  • Auto Mode: Dyson will detect current air quality and automatically adjust as needed to most effectively treat the air turning up or down as needed.
  • Custom Mode: It allows you to select a custom fan speed ranging whether or not you want the air blowing towards you out away from you which is good for varying reasons. Oscillation can be customized ranging from 0 to 350 degrees.
  • Night Mode the sleep timer can be set ranging from 0 to 8 hours automatically shut off when the timer is complete.

App Control

Both Dyson and Molekule can connect to a smartphone-based app. With functions such as:

  • Turn the purifier on or off
  • Check the current air quality
  • Send notifications to your smartphone
  • Configure the space and how much to clean
  • Change models
  • Monitor filter replacement schedules
  • Go into a dark and quiet setting for nighttime use.

The app gives you control of the purifier with your phone even if you’re not nearby. The Molekule app has problems connecting with the device while the Dyson app connects easily within 6 to 7 minutes.

Air Quality Assessment

Both of them have technology that can detect air quality conditions and adjust the purifier accordingly.

In Molekule, this process is called Initial Clean Up and it’s the first step that takes place when the purifier is on. During the Initial Clean Up, the Molekule will gauge the current air to good standings. This process can take up to 50 minutes.

With Dyson, the air quality assessment is more of on-going thing. The digital screen at the base of Dyson has a little graph that shows the current air quality and it will let you know when the quality drops to poor conditions. When in Auto Mode, both Molekule and Dyson can self adjust fans speed and duration to work until the air is clean turning up or down as necessary.


One feature the Molekule lacks but is found in most Dyson purifiers is oscillation. The exact range of oscillation varies by model but spans from 0° to 350°. Molekule purifiers don’t have the ability to oscillate.


Within 1 hour, Molekule removes 88% of air particles from a medium-sized room and improves air quality by 90% Dyson removes 98% of air particles from a medium-sized room


Molekule Noise: 39-65 decibels

Dyson Noise: 40-56 decibels

The ambient noise which is the soft hum of noise that occurs in most environment.  Molekule shows that ambient noise can have an effect on overall noise output.

Setup and Usability

Getting started with purifiers is a painless process. 

Both models come fully assembled. 

They just need to be plugged to get started.

Once you plug in Molekule air purifier, you simply select room size and mode (silent, auto or boost). Next, it will begin the Initial Clean Up can take up to 50 minutes. You can then change mode/adjust fan speed (Auto, Boost, Silent, or Dark Mode), Turn on/off and Turn on standby.

Setting up Dyson

Dyson’s setup is also easy. It requires no Initial Clean-Up or waiting period.


This boils down to the filters which are the most critical parts of each air purifier. Molekule maintenance requires replacement of its pre-filter once every 6 months while Dyson’s requirement is to follow digital app-based prompts on replacement frequency for the HEPA filters as well as the activated carbon filter. You will need to replace the filters every 6-18 months depending on use.

Replacement filters for Molekule and Dyson are directly available from the manufacturer’s website or 3rd party retailers like 


This depends on customer preference. Both manufacturers offer high-end good quality purifiers with detailed design.

They are both recommended for medium-sized rooms and have a similar price.

Want the best performance: Between the Molekule vs. Dyson, the Dyson TP04 outperformed the Molekule during our tests. It is even more impressive considering the initial baseline measurement showed poorer air quality than the quality of air that the Molekule tested in.

Want more options: Dyson has a much wider selection of purifier models on the market than the Molekule. If you’re looking for different sizes, styles or features, you may be pleased with some of the other models that Dyson has available.
