Performance
So let’s talk about performance. As mentioned above, the Molekule air purifiers are designed differently than traditional HEPA air purifiers.
HEPA vs. PECO: What’s the difference?
HEPA filters are paper based and use intricate folds to trap particles down to 0.3 microns. Once the filter is full, you simply throw it away and replace with a new one.
PECO filters rely on Photo Electrochemical Oxidation, which is a technology proprietary to Molekule. This technology uses a special filter that is activated by light shining onto the filter membrane.
The light destroys the particles instead of capturing them, which some claim is a more effective technique for air purification.
Do they actually clean the air?
The short answer is yes.
When we tested all three of these purifiers in our testing lab, we noticed significant improvements in overall air quality with and without the purifier.
Here is our data below. Here’s how we did it:
- Take a baseline measurement in the room to evaluate air quality before testing.
- Run each purifier for 1 hour.
- Take another air quality measurement to gauge performance
And here’s the results from each Molekule air purifier.

The Design
The design of the Molekule air purifier has quite a few similarities between all three models.
Design Similarities
The Molekule Air, Air Pro and Mini all have round bodies with air intake at the bottom and outlet at the top.
Molekule uses a blend of machined parts with natural or simple materials for a sleeker look.
They also all have a carrying handle, although the exact material of the handle varies.
Design Differences
The Handle
- The Air and Air Pro use a natural leather handle that spans across the entire width of the purifier.
- The Mini has a smaller felt loop handle that starts and stops at the same spot
The Shell
- The Air and Air Pro have a metal machined shell with a brushed aluminum finish.
- The Mini has a matte white body with simple light gray accents.
Size & Coverage
Aside from design, size / area coverage is one of the biggest differences between these three Molekule purifiers.
Best Balanced: Molekule Air
- Width: 8.25″ diameter
- Height: 23” tall
- Weight: 18 lbs.
Max Coverage: Molekule Air Pro
- Width: 11″ diameter
- Height: 23″ tall
- Weight: 22.9 lbs.
Most Compact: Molekule Mini
- Width: 8″ diameter
- Height: 12″ tall
- Weight: 7.3 lbs.
While all three of these purifiers use similar technology, the larger sized units do translate to greater area coverage.
Here’s a quick look at the max area coverage of each purifier.
Air
600 sf.
Air Pro
1,000 sf.
Mini
250 sf.
The Controls
The controls for all of these Molekule air purifiers are located at top of the purifier. All models are touch screen displays with LED lights to signal different features or settings.
The Molekule Air has the central controls in the middle of the purifier as well as an LED light ring that circles the perimeter of the purifier.
The Molekule Air Pro redesigns the center control, which shows a brighter display and has a more subtle LED outer ring.
The Molekule Mini has the simplest center controls. In fact, may users may not even realize that they’re there.
Instead of having a central display with colored LEDs and text, the Mini just uses small LED dots to simulate varying fan speeds. It’s simple, straightforward, and quite clean.
Is there remote control?
While there is no physical remote control with any of the Molekule air purifiers, two out of the three can be controlled via a smartphone
Air
Yes
Air Pro
Yes
Mini
No
The Molekule Mini does not have wifi connectivity so it can only be controlled on the top of the unit itself.
The Molekule Air and Air Pro can be synced up to your smartphone via app for remote control.
Using the app, you can remotely:
- Turn the purifier on / off
- Check the current air quality
- Send notifications to your phone
- Configure the space / how much to clean
- Changes modes
- Monitor filter replacement schedules
How does it work?
The Molekule air purifier has four different modes it can run in:
- Auto Mode: allows users to input information about your room to help determine optimal purification settings
- Boost Mode: runs the purifier at full power until you change the mode; good for maximum purification
- Silent Mode: runs the purifier at minimum power with the lowest possible sound output (approx. 40 dBa)
- Dark Mode: dims all lights for night time or purification while sleeping, but keep in mind that PECO technology requires light to destroy particles. Without light, the purifier will simply store the bacteria until you turn Dark Mode off when it will turn the light on and destroy the particles
The Molekule Air Pro air purifier has 6 different fan speeds and two specialty modes.
- Manual Mode: allows users to specify 1 of 6 different fan speeds
- Auto Mode: uses real-time air quality to select fan speed, automatically adjusts as air quality changes
- Quiet Mode: runs fans at lowest possible decibel setting for more discreet usage
The Molekule Mini is the smallest and simplest purifier in this lineup. It lacks Auto Modes or Quiet Mode, but has simple controls to manually adjust the fan speed.
- Manual Mode: allows users to specify 1 of 5 different fan speeds
Parts & Accessories
The parts and accessories included with each Molekule is similar between these three models.
Similarities
All three Molekules come with the purifier base, filter, and the shell that installs into the base and twists to lock it on.
They are all corded units and have a cord wrap designed into the bottom of the purifier base.
Differences
The main difference is the filters.
The Molekule Air uses two different filters, while the Air Pro and the Mini use a hybrid filter that combines the two separate filters into a single filter.
The Molekule Air comes with a prefilter and a PECO filter.
PECO Filter
Pre-Filter
The Molekule Mini and Air Pro come with:
- Base
- Hybrid PECO Filter
- Outer Shell
Setup & Usability
Setup between all Molekule models is also pretty similar.
For the shortest setup, the winner is the Molekule Mini and this is primarily because there’s no WiFi so you don’t need to link your phone or local internet with the purifier.
The original Molekule Air or Air Pro will take a little extra time to set up the app, but the time you spend on the initial setup will come back two-fold in time saved during regular use, but being able to control the purifier with your phone.
RELATED: Molekule vs. Dyson air purifiers
Here’s the rundown of how to set up the Molekule.
- Push down and twist off shell counter-clockwise, pull out the PECO filter.
- Unwrap PECO-filter and place on base.
- Align logo on shell with arrow on base. Close shell and twist to lock.
- Unwind cord and plug in.
- Use the controls on the top of the unit to manually select fan speed.
If you opt for the Molekule Mini you’re done here.
If you have the Molekule Air or Air Pro, you can continue on the next two steps.
- Download the Molekule app onto your smartphone.
- Follow in-app prompts to pair it with your device.
NOTE: If you have the original Molekule Air, you will also need to follow the setup guide to make sure the pre-filter is properly installed prior to running for the first time.
What is “Initial Clean Up”?
The Molekule Air and also has a required setting called, Initial Clean-Up.
This is basically an initial assessment of the room, where the air purifier can customize its settings based on the exact size and location of your room, to ensure proper fan speeds and modes are used.
NOTE: The Initial Clean Up cycle could take as long as 50 minutes.
Maintenance
Maintenance between all three of these models is about the same. The two main tasks for proper maintenance includes:
- Use a dry cloth to keep the air intake and outlet free of dust or particulates.
- Replace the filter as needed.
They all use a PECO filter, which is a little different compared to traditional HEPA filters.
The Molekule Air uses two filters, while the Molekule Air Pro and Molekule mini use a single hybrid filter for purification.
FYI: The Molekule Mini hybrid filter is slightly less expensive to replace compared to the Molekule filters ($99 for the Mini filters vs. $130 for the full-size Molekule filters)
Molekule filters are designed to last about 6 months.
With the Molekule Air or Molekule Air Pro, you can opt-in for the Auto-Refill program. This is done via the app which then monitors the remaining filter life remotely and orders a new filter when it’s time to replace.
Since the Molekule Mini lacks wifi connectivity, this program is not available with that purifier.
Which Molekule is the best value?
If you’re most concerned with value, the best value Molekule would be to get the unit which has a max coverage closest to the size of your area. In other words, don’t pay for coverage that you can’t use.
If you have a small space, the best value would likely be the Molekule Mini, with max coverage around 250 sf.
For a larger space or if you plan on moving the purifier back and forth between a small and larger space, the best value would likely be the original Molekule Air purifier.
Lastly, if you’ve got an open space or want the most opinions in terms of coverage area as well as operating modes, check out the Molekule Air Pro.
