Molekule Budget-friendly

Another option for a more budget-friendly item from Molekule is this mini small room air purifier.

The auto protect function helps to detect the pollution rate and adjust the setting to handle the situation. But without this, you can still know the pollution rate shown on the app specification, but you have to do some self-adjustment.

How to Choose the Best Molekule Air Purifiers


Molekule purifier is rated by many users as the best design air purifier on the market. It has a cylinder shape with round edges and painted white, creating a clean look and easy to blend in room furniture.


The Dual-Filtration is the combo of the PECO filter and pre-filter. Pre-filter function is to block the large substances that the PECO filter cannot wholly oxidize, such as dust, sand, animal fur.

After the pre-filter, the particles at the molecular level that are contained in the air will be destroyed by the PECO filter.

Control Options

Molekule offers two methods of control: by app and by touch display. The machine has no button on its body. When you need to use it, just tap the functions on the touch display on the top.

Or else you can utilize the app, and it works based on wifi connection. The app shall display every function of the air purifier and is simple to adjust as well as understand. For resetting the Filter Status Indicator, it will be easier to use the app.

Noise Level

Molecule performs a great job with the noise feature. While operating, the machine keeps the noise of less than 65 dB (the highest speed). At this rate, the sound won’t catch your notice and is manageable for sleep.

About the Brand

Molekule Brand

The story of the Molekule brand originates from the story about the father and the son. Dr. Yogi Goswami (the chief scientist) has a son who suffers badly from asthma, which is deeply affected by polluted home air.

So he jumped to 20+ years of science and finally created a breakthrough purification technology: PECO (Photo Electrochemical Oxidation), which is the tech they apply to all the Molekule air purifiers nowadays.

In 2014, the family with 2 siblings and a father and a team of scientists from all around the world launched the Molekule industry. They want to share the PECO technology to the world with an envision of every house, school, hospital, office in the world will breathe in clean, pure indoor air.

PECO filter vs. HEPA filter

Molekule’s PECO filter and the HEPA filter are both made to block the bacteria from the air. But each one uses a different strategy and has its own benefits as well as drawbacks.

HEPA Air Purifier

HEPA stands for high efficiency particulate air. It can capture all particles and substances from 0.3 microns.

The filter is made of fabric fiber, it takes some physical terms to describe precisely the machine working process, but you can pretty much imagine that this filter is a net that holds very small pollutants. To American standards, the HEPA filter offers 99,97% clean air to the room.

HEPA air purifiers usually come in a bundle of filtrations, which usually includes the pre-filter, which captures large particles, fur, dust. Charcoal filter and carbon filter helps retain odor and germs.

HEPA filters only hold the bacteria, not eliminate them. Small air pollutants are tiny and very light such as VOCs. These chemicals may trap for a while, and later on, they can follow the air molecules to pass through the filter and be propelled out with the breeze.

After a time, you need to replace a new one since the used HEPA filters are full of toxins.

In conclusion, HEPA filters are effective in capturing large particles and smell, but there is still a chance for tiny pollutants to escape.

We also have a great candidate for HEPA air purifier, it works very effectively with 5 air filtration steps and is an economical choice.

PECO Air Purifier

PECO is the short form of Photoelectrochemical Oxidation. Purifiers with PECO technology don’t hold the pollutant, but destroy viruses. So there is no worry about later disposal.

PECO filter contains fiber with a nanocatalyst. When the bacteria trap in the filter, it starts the chemical reaction and destroys them, or for more precise, it transforms them into trace elements, water, and carbon dioxide.

PECO filters can handle bacteria that are smaller than PM1 (smoke), so it is ideal for rooms with smell, gas, VOCs, etc.

However, there is a big drawback of this process; if the particle is too large, they cannot be oxidized. However, the problem is solved when the manufacturer added a pre-filter to hole the large substances back, helping the PECO filter oxidation process.

So, in conclusion, PECO air purifier is a bright candidate on the air purifier market for any house to have.


How Does the Machine Work?

The Molekule operates based on the method that all the air purifiers use. But the key difference is the PECO technology, which is an innovation from the Molekule brand.

The machine takes the surrounding indoor air 360 degrees to its space. After that, the air comes through the pre-filter, which retains big particles, like sand, fur, and dust.

The air then keeps following the vent to the PECO filter. At this stage, it makes a chemical reaction and destroys pollutants, small bacteria and, at last, pushes out pure air. As a result, the device increases tremendously the air quality inside the house.

How Often Do I Need to Clean?

The recommended period to clean the machine or to change the PECO filter is after every 6 months, and 3 months for the pre-filter. But based on the pollution rate, the time can be extended or narrowed down.

The filter replacement step is really easy to implement. When the app tells it is time for filter changing, just simply take out the pre-filter and then the PECO filter. Next, install the new filters and plug in to let the machine work.

How Do I Reset the Filter Status Indicator after Changing Filter?

The Molekule Air Pro, Mini +, and the Mini version is automatically reset by itself.

For other devices, you can use the mobile app to reset the status as the step are as follow:

  1. From the Molekule homepage, tap to the Filter Status Indicator tag.
  2. When the screen changes, press the Reset Filter tag.
  3. As the Reset Filter pop-up, choose to reset the filter you have just replaced (pre-filter or PECO filter).

Is It Easy to Get a Replacement Filter?

Both pre-filter and PECO filters are non-washable, so you have to buy a brand new one. It is best to purchase from the manufacturer as other filters may not guarantee the same result as the brand’s ones.

How should I store my extra filter?

If you buy an extra filter for more convenience for the next replacement, make sure you put the filter in closed spaces with the least VOCs or least exposed to fumes from cooking and fire. The best is not to take it out from the box it comes in until the next use.
