Introducing PECO.

Molekule’s patented technology, Photo Electrochemical Oxidation (PECO), works at the molecular level to eliminate indoor air pollution. Take a deep breath and see what makes Molekule the first of its kind.

Science at the nanoscale.

Developed over two decades by research scientists, PECO is an innovative technology that utilizes free radicals—the same radicals used to kill cancer cells—to oxidize pollutants. By using nanotechnology, PECO is able to destroy pollutants 1000 times smaller than traditional HEPA filters (0.1 nanometers versus 300 nanometers).

Under the microscope.

Unlike HEPA, PECO can eliminate pollutants at a microscopic scale (including VOCs and viruses), making Molekule the only product that eradicates the full spectrum of indoor air pollutants. These claims have been extensively tested by third party laboratories, and in the spirit of scientific transparency, Molekule also publishes all of its performance data.

Airborne Chemical (VOCs)

(on 1000 parts per billion)


Independent lab results have shown that PECO destroys VOCs quickly and efficiently. VOCs are too small to be captured by even the best-in-class HEPA filter. Carbon filters, while able to capture some chemicals initially, re-emit these same chemicals back into the air.


(on 9.7 million e. coli bacteria)


Bacteria can easily stay alive on traditional HEPA filters. Studies have shown that bacteria can multiply on these filters and get released back into the air. Even if the bacteria dies they can still release endotoxins into the air if not properly eliminated. Molekule breaks down even the smallest bacteria before they have a chance to accumulate.


(on 3.4 million black mold spores)


Mold spreads through the air and finds surfaces to grow on. While HEPA filters can catch mold, they also become perfect places for mold growth. Eventually, this mold gets released back into the air. Because nothing is collected during the Molekule process, mold is quickly and permanently removed from the air.

More About Mold


(on 3.4 million MS2 viruses)


Viruses are so small they can easily escape HEPA filters, but even if they are caught on the filter they can live there for up to 200 days. PECO offers the first effective solution for managing the spread of airborne infectious diseases. In just two minutes, Molekule can eliminate millions of airborne viruses that are brought indoors.


(on 1 million allergens)


While the pre-filter will catch the larger dust particles in the air, PECO will break down even the smallest allergens, like pollen, dust mites, and dander to provide truly allergen free air.

Real People. Real Proof.


Our beta trial was conducted on 28 participants including asthma and allergy sufferers. After using Molekule, there was no difference in total symptom score between allergy and non-allergy sufferers. Results point to the potential for Molekule to immediately improve allergy sufferers quality of life.

Allergy Sufferer Relief

These benefits are a breath of fresh air.

Big Rooms Are
No Big Deal


Molekule can completely replace the air in a 600 square foot room once every hour. And it is also fully portable so you can easily move Molekule from room to room.

Never Run Out
Of Filters


Molekule’s annual filter subscription ensures you never run out of filters. Replacements are delivered to your door when you need them. The service costs just $129 a year, and the first year is free.

Ozone Destroyed,
Not Produced


Molekule’s unique technology doesn’t emit ozone or any other harmful byproduct. In fact studies have shown it can reduce the concentration of ozone in the air.
