Molekule Review

Last Updated on

This sleek, cylindrical air purifier has created quite a buzz of late, and rightly so. It’s advertised to destroy viruses, bacteria, molds, and gaseous chemicals lurking in the air you breathe. The manufacturer has also made revolutionary claims about the Molekule air purifier, sensationally pegged on its proprietary PECO technology. But what exactly does it do, and does it really work?

What Is PECO?

PECO is an acronym for Photoelectrochemical oxidation. This technology is relatively new and borrows heavily from photocatalytic oxidation, commonly referred to as PCO, which has been in use for decades to clean contaminated water and air.

Conventional mesh filters only capture airborne particles, whereas PECO and PCO take it further than that. The latter technologies filters have catalysts, like titanium oxide in PCO, which reacts with UV light, oxidizing gaseous pollutants, and breaking them down to harmless molecules. However, the Environmental Protection Agency places a red flag on PCO, observing that it can also react with many pollutants not typically found in a home, generating hazardous byproducts like carbon monoxide, formaldehyde, nitrogen dioxide, and ozone.

PECO claims to have all the advantages you can get with PCO while doing away with the shortcomings. When compared to PCO, Molekule’s proprietary PECO innovations have a different coating, filter, and UV lighting, all geared towards improved speed and efficiency. In other words, mold spores, viruses, bacteria, and harmful gasses are destroyed, without emitting any toxic by-products, thanks to the molecule air purifier.

How It Works

This air purifier has a pre-filter that captures large particles like pet hair and dust. Air that passes the outside filter must go through the patented PECO filter, which even destroys particles volatile organic compounds (VOCs). VOCs are organic chemicals that have high vapor pressure at average room temperatures. This system works differently from traditional carbon filter or HEPA filter, both of which trap the pollutants, rather than obliterating them.


The Molekule home air purifier has a futuristic and minimalistic design that adds to the décor of any room. The outer surface is 23 inches (0.58 m) tall, with a diameter of 8.25 inches (0.21 m), and is made of machined aluminum for a sleek look. Its size is not small, neither is it obtrusive. It comes in at a measly 18 lbs. There’s also a carrying handle made of leather, which completes the look while you move it between rooms. The nano-filter is lit with UV, which catalyzes the chemical reactions taking place, as well as add to the aesthetics.

The user interface is simple to use once you get the hang of it. First-time users find the touchscreen display challenging to operate as they swipe left or right to get all manner of settings. Some go-to controls are simple, auto, silent, and boost modes. You can also control it using the Molekule app, available on Android and iOS devices. It also has wi-fi connectivity for easy remote control. You can check the current air quality, receive notifications to your phone, configure the space you need to clean, keep track of filter replacement schedules, and change the modes from the touchscreen or app.

More on The Modes

For the auto mode, you can input the size of the room of up to 600 sq. Ft. and the purifier does a full air exchange up until the next cycle, dynamically increasing or decreasing the filtration speed. For starters, all you need to input is the size of the room, which determines the optimal airflow in that space. In boost mode, the purifier runs a full power, suitable for particularly dirty air or right after vacuuming or dusting a room. The third option is silent mode, which has the lowest sound output, as little as 40 dB. To put the figure in perspective, that’s more like the noise or lack of you would find in a library. The final mode is dark, where all lights are dimmed for a peaceful sleep environment. However, since the Molekule air purifier needs light to activate the PECO filter, bacteria are stored until you change modes, where it will continue in its work of treating the pollutants.

Molekule Air Purifier Reviews

According to those who already have the device, there is little to complain about. The initial cost is quite high at nearly $800, and you can only get it from the manufacturer. Additionally, you will also need on average to replace your filters per annum, which will push you back another 130 per year. Nonetheless, the quality, aesthetics, and functionality are unrivaled when compared to other purifiers. In high-speed settings, the noise is tolerable, and when on low-speed settings, it’s very quiet.

Why It’s Better

This air purifier is very different from the commonly found HEPA filters (High efficiency particulate air filter) and in a good way. HEPA filters work with the hope of catching small micropollutants through the big sheets of fabric. However, some micropollutants like mold or bacteria can thrive in a HEPA filter environment. This is obviously a problem since you might have done more harm than good by releasing the increased micropollutants, which won’t be the case thanks to the PECO filter. Molekule’s technology works actively and not passively like a HEPA filter. Everything from large particles and small particles like viruses and VOCs, which regularly pass through the HEPA filter, have little to no chance of escaping the molecule air purifier.

The Bad

The price will make most people scoff at the product, but once they understand the advantages over HEPA filters, they sometimes reconsider. Additionally, the maintenance cost is quite high. According to some Molekule air purifier reviews, some users find difficulty in connecting to the app.


Instead of just filtering the air, the molecule air purifier destroys the harmful chemicals in the air. The proprietary nano-filter is coated in a catalyst, which breaks down micropollutants, addressing the whole spectrum of indoor air pollutants, both large and small particles. Its design makes it blend well in many settings like hospitals and airplanes, where good air quality is a necessity. Air purified at a nanoscale level is safer. It’s quite clear that Molekule didn’t try to improve on HEPA filters like many of their competitors and instead started from the ground up for the design.
