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 what traditional HEPA filters can trap.

Under the microscope

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

Destroying airborne chemicals (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 can get released back into the air. Because Molekule catches and oxidizes mold spores at the molecular level, mold is quickly and effectively removed from the air.


(on 3.4 million MS2 viruses)


Viruses are so small the can easily escape HEPA filters, but even if they are caught on the filter, they can remain viable for up to 200 days. PECO offers the first effective solution for safely destroying airborne viruses. In just two minutes, Molekule can destroy 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 clean air.

The Molekule Effect.


Molekule's PECO technology has been tested by real people in an allergy beta study published in the Journal of Allergy & Rhinology. The experiment was conducted on 46 participants who had previously reported asthma and allergy symptoms. Read the report to see how Molekule performed.
