The threats of viruses and harmful particles are always in the air we breathe, even when we are in our rooms. Many brands came up with air purifiers to our rescue. But the most prominent name that we can think of is Molekule. Here I will review several models of air purifiers offered by this brand, and I will also share my personal experience that will throw some extra light on the products.

Molekule is a reputed brand that does not need any separate introduction. The brand is deeply committed to only one motto: providing fresh and clean air to breathe. They introduced PECO or Photoelectrochemical Oxidation technology which added a new definition to the purification of air. This technology has been implemented in all their air purifying machines.

Molekule offers an array of models based on PECO technology. The models include Molekule Air Mini/Mini+, Molekule Air Purifier and Molekule Air Pro. They are available in different price ranges with various features.

Molekule Air Mini+ is perfect for small rooms of about 250 sq. ft. On the other hand, if the room is larger, then Molekule Air Purifier and PECO Filter Bundle will be a suitable option. Apart from home, the brand also has a model that guarantees freshness in your professional area. Molekule Air Pro is based on PECO technology.

The models come along with different features and price ranges. Molekule Air Mini+ costs $499.00 without discount, Molekule Air Purifier costs around $700, and Molekule Air Pro price is way above $1000.

Molekule Air Pro Review

What’s in the box

  • Molekule Air Pro unit w/ 1 PECO filter
  • User Manual

I am an owner of Molekule Air Pro, which I purchased about a couple of months back. Out of so many options in the market, I was pretty confused initially as to which brand would be perfect and suitable as per my requirement. I also had to stick to my budget.

After a lot of research, I finally purchased Molekule Air Pro, which I needed for my large room. I want to share my experience, including all the features and the design and looks in detail. But to be very honest, the product did not dishearten me completely.


The product looks fantastic but is a bit heavy. The weight of the device is approximately 10 kilograms. It is 23 inches tall and 11 inches in diameter. It is perfect for my 900 sq ft area as the device can treat about 100 sq ft area. The design is quite trendy and is very easy to set up. It is a bit larger than the original Molekule model.

Molekule Air PRO

It has a brushed aluminum finish that adds to the aesthetic look of the room. The white base enhances the look of the device. The device is portable despite its weight. Thanks to the vegan leather handle! The power cord can be wrapped around the base when not in use, giving it a clean look.

There is a touch screen at the top of the device from where I can operate it. This touch screen displays the modes and also the quality of the air. Though there is no physical remote available for this device, an app is available, which I have installed on my phone and use it to operate the device instead of walking to the machine. Needless to say, that the app pairs seamlessly with the device, making it exceptionally comfortable for me to use.

The device consists of three pieces; the upper part of the device includes the touch screen panel; the other part is the filter, which consists of the pre-filter and the PECO filter. The third part is the shell in which the filters are placed. The setup is easy without any complications.


After setting up the device once, I switched it on; I was surprised by the very low sound that it emits. The sound did not interfere with the serenity of the room at all.

It did surprise me the way it changes the speed after it detects the air of poor quality. Even if I light a candle or the fireplace, the device senses an abnormality in the air quality, and the motor speeds up to high gear automatically!

When I turn on the device at full speed, it covers more air. The quality of the air is displayed on the screen. The device works in two modes which are quiet mode and standard mode. The first one is definitely quit and don’t bother me at all.

Initially, I was a bit concerned about the power consumption despite the company’s promise that the device uses less energy. But I was happy to see that even it runs the entire day and night, the power the device consumes is less.


Molekule Air PRO PECO replacement filter

Molekule uses the PECO or Photo Electrochemical Oxidation nanotechnology. This fantastic technology is beneficial, which I can say from my own experiences. It helped me get rid of the allergies that I used to suffer from before purchasing this product. This technology destroys harmful airborne viruses, bacteria, molds, and allergens.

The filter even does not fail to capture the dust particles and other large unwanted particles which float in the air. However, I can’t deny that the price is a bit too high, but it was a good investment. Surprisingly I even found the furniture in my room dust-free.


Before purchasing, I went through some reviews that complained that the device emits a distracting sound and disturbs sleep. However, after the purchase, I was again proved wrong as the sound it emits can merely be heard.

The device is quiet in the normal mode but emits a sound of the fan speed when it detects something to combat in the air. But this sound is also that loud that it will disturb my sleep. The sound is even not as loud as the refrigerator.

The sound level changes from 61 to 63 decibel, too, when the fan speed is high. So it is not that noisy! I have seen other conventional air purifiers at my friends’ place. But Molekule Air Pro is almost soundless in comparison to those. Thanks to its unique technology!


The price of this device is $1199.99 approximately which is quite higher than any other conventional air purifier available in the market. But to be very honest, I did not give it a second thought to invest this amount.

The way it functions and its usefulness is quite adequate, and I became an admirer of this brand from the day it freed me from my allergy-related complications!

But of course, the filters are pretty expensive if it needs to be replaced every six months. The cost of the Molekule PECO air filter is $79.00, which is not quite pocket-friendly.


Every Molekule device comes along with a detailed user manual, making it easier for the user to install it. The manual starts with Best Practices’ which help in the long run.

The manual includes diagrams that make it easier to get the device installed all by you within minutes. It also provides vivid details about the Controls and interface, Modes and states, fan speed selector, which includes the instruction on how to swap between Auto protect and Manual modes.

It also states about the Settings and teaches you about how the device works, which is also helpful. The manual even guides you with detailed diagrams on how to replace the filter. So if you follow the manual, setting up this device is very simple!

How to use

Once you unbox the device, you will find the power cord wrapped around the base. You can pull it out as per the length you need to reach the power socket. There is a filter inside, and once we put the top lid-like structure, we can switch it on. It might take some minutes to boot.

After the booting is done, you can install the app on your phone. You can follow the instruction that is being shown like connecting it to the device or the WiFi. The app is the perfect way for you to communicate with the device. It will guide you through the status of the device and let you know when to replace your filter.

After the device is paired with the app, you can select the auto mode or the manual mode. You can also change it to standard or quiet. If you are not quite comfortable using the app, do not worry because there is a touch screen at the top of the device to find all the instructions. The screen will display the status of the air in your room, whether it is good or bad.

Suitable Room Size for Molekule Air Pro

Molekule Air Pro is advertised for rooms 1000 square feet in size, but unfortunately the company does not provide any details on the amount of air moved per hour (CFM). It does not provide the data even in their manual.

It is possible to figure out CADR using the calculator, but to do that the company has to specify air changes per hour for the specified room size. But Molekule doesn’t provide that!

I can only speculate that if the advertised space coverage means 4 air changes per hour then CFM could be around 530. If this is the case, then the Molekule Air Pro definitely worth the price since it can definitely clean air continuously in large spaces and be very effective in eliminating odors, gases and harmful bacteria. Good option for asthma sufferers too.

If the manufacturer puts 2 ACH as their target for air cleaning, then the airflow is about 270 CFM. Let alone 1 ACH with 130 cubic feet per minute airflow. If that is correct, Molekule Air Pro is overpriced and you better look for some alternatives. Some of them I listed below (and they are cheaper too!).

But again, it’s all speculation and thus I cannot say whether it’s really does it job for large spaces or is it only effective for small and medium rooms.

Molekule Air Pro Maintenance Costs

Replacement Filters: ~$150 per 1 PECO filter that has to be replaced every 6th month. Check price & availability.

Electricity Costs: ~$8 per month running 12 hours per day on Maximum speed. Use our Energy Consumption Calculator to estimate electricity usage and costs of the Molekule Air Pro air purifier based on your local electricity rates.

Total Costs Per Year: 2 PECO Filters (~$300) + Electricity (~$100) = $400.

Maintenance Tips

Regardless of the fact how expensive your air purifier is, proper maintenance is a must. It will increase the life of the device and save you high repairing cost in the long run, as the better you maintain the device, the more it lessens the chances of taking professional help if needed.

The first thing you need to keep in mind regarding maintenance is that you should change the filter whenever required depending on how frequently you use it.

The maintenance of the Molekule Air purifier involves only a few steps. You just need to wash the plates (depending on the model) of the filter regularly.


Here is a list of some common questions which a customer may ask.

Are PECO filter auto refills available?

The device, when purchased, comes along with one PECO filter. Once the device alerts you that it is time to refill, you need to place an order for a new filter, and it will be delivered to your doorstep within a given timeframe.

When the device is in manufacturing, it comes across some volatile organic compounds or VOC. It might take 24-48 hours for the odor to dissipate. The bag of activated carbon that is provided along with the device helps in absorbing the odor.

Why doesn’t the device switch on at times?

If the device does not turn on, then ensure the following and follow these simple steps:

There is no problem with the power socket.

The PECO filter is not wrapped.

Once the PECO filter is inserted into the device, wait till the status light indicator turns green.

Yes, Molekule Air Pro supports WiFi signals.

IQAir has similar price to Molekule Air Pro air purifier, but it does things a bit different. First off, the manufacturer does specify CADR, so you can decide whether the unit suits for your room or not.

Secondly, the manufacturer focused on reducing allergens and helping asthma sufferers whilst designing IQAir HealthPro Plus. It is very efficient in eliminating viruses and bacteria that cause negative effects on people’s health.

We go into more details in our IQAir HealthPro review, the link is below.

IQAir HealthPro Plus Air Purifier Review


Molekule is definitely quite controversial air purifier that become known due to the aggressive marketing strategy. On one hand it does good at eliminating VOCs from the air and improving air quality, on the other hand it’s pricey, the manufacturer hides crucial information about purifiers CADR capabilities and the highest-priced model aren’t capable of covering large rooms.

Overall, you should probably at least take a look at other available air purifiers before buying any Molekule air purifier.
