Molekule’s Patented PECO Technology

Molekule’s proprietary technology, Photo Electrochemical Oxidation (PECO), works at the molecular level to destroy pollutants. Take a deep breath and see what makes Molekule air purifiers the first of their 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 destroy cancer cells—to break down pollutants at a molecular level, including VOCs, bacteria, mold, viruses, and allergens. By using nanotechnology, PECO is able to destroy pollutants 1000 times smaller than the standard filters must meet to qualify as HEPA.

  • Free Radical (OH)
  • Oxygen (O2)
  • Virus (C,O,H,N)
  • Carbon Dioxide (CO2)
  • Water (H2O)
  • Trace Elements (N2, etc)

Under the microscope

PECO destroys pollutants at a microscopic scale, including VOCs and viruses 1000x smaller than what the HEPA filter standard even tests for. With no ozone byproduct, Molekule air purifiers safely destroy a vast range of indoor air pollutants. As a science company, Molekule conducts extensive testing of its technology through its own labs as well as certified third-party laboratories.

Destruction

Black mold is oxidized and destroyed.

RNA virus MS2: Over 99.999% removed in 2 hrs*

Molekule Air Mini can help to remove airborne viruses like bacteriophage MS2, which travel in tiny aggregated droplets that can linger for hours before they settle on surfaces.  

Testing location and standard

Tested at Aerosol Research and Engineering Laboratories in a 16 m³ chamber on MS2 Bacteriophage aerosolized droplets.

*Pollutants were not re-released into the chamber after initial introduction. Device operated on the highest setting. Just note that no air purifier can prevent you from getting a virus.

DNA virus PhiX174: 98.7% removed in 2 hrs*

Molekule Air Mini can help remove viruses which otherwise could linger for hours in the air, then PECO technology destroys them. The PECO filter was also cut, sampled, and incubated to measure viable virus count. Zero viable virus was detected.  

Testing location and standard

Tested at Intertek-Columbus in a 30 m³ chamber on ΦX174 Bacteriophage aerosolized droplets.

*Pollutants were not re-released into the chamber after initial introduction. Device operated on the highest setting. Just note that no air purifier can prevent you from getting a virus.

Air Mini reduced all pollutants tested*

Indoor air is a complex mixture of chemical compounds that varies from building to building. Even when challenged with a blend of organic pollutants, Molekule Air Mini is working to purify and make naturally clean air.

Test location & standard

Tested per GB/T 18801-2015 Protocol in a 30 m³ chamber at Intertek-Grand Rapids.

*Pollutants were not re-released into the chamber after initial introduction. Device operated on highest setting.

Formaldehyde: 59% removed in 8 hrs*

Molekule Air Mini destroys toxic volatile organic compounds like formaldehyde, which is a stable substance that is difficult to remove from indoor air. It can enter your home as part of industrially manufactured products like furniture, flooring, or clothes and is a significant portion of cigarette smoke.

Test location & standard

Tested per GB/T 18801-2015 Protocol in a 30 m³ chamber at Intertek-Grand Rapids.

*Pollutants were not re-released into the chamber after initial introduction. Device operated on highest setting.

D-Limonene: 99% removed in 3 hrs*

Unpleasant natural and artificial smells in the air like limonene are destroyed by Molekule Air Mini. Lemon-scented cleaning products commonly contain limonene, which can cause allergies.

Test location & standard

Tested per GB/T 18801-2015 Protocol in a 30 m³ chamber at Intertek-Grand Rapids.

*Pollutants were not re-released into the chamber after initial introduction. Device operated on highest setting.

Toluene: 98% removed in 3 hrs*

Solvents in paint such as toluene can linger in your home for extended amounts of time, but Molekule Air Mini can destroy them so they aren’t inhaled.

Test location & standard

Tested per GB/T 18801-2015 Protocol in a 30 m³ chamber at Intertek-Grand Rapids.

*Pollutants were not re-released into the chamber after initial introduction. Device operated on highest setting.

Smoke: 84% removed in 22 min*

Molekule Air Mini’s filters can strip particles of this size range out of the air quickly, which include the invisible components of smoke. They can be easily inhaled into the lungs and transferred to the blood, where they can be distributed throughout the body and damage internal organs.

Test location & standard

Tested per AHAM AC-1 Protocol in a 27 m³ chamber at Intertek-Cortland.

*Pollutants were not re-released into the chamber after initial introduction. Device operated on highest setting.

Dust: 82% removed in 20 min*

Floating dust can harbor dust mite shells and other dirt which are the most common cause of allergic reactions. Where Molekule Air Mini is running, there are fewer dust particles.

Test location & standard

Tested per AHAM AC-1 Protocol in a 27 m³ chamber at Intertek-Cortland.

*Pollutants were not re-released into the chamber after initial introduction. Device operated on highest setting.

Pollen: 79% removed in 10 min*

Pollen, pet dander, and other particles lie in this size range and can be sources of allergies and other respiratory problems. Molekule Air Mini can capture them from the air.
