Molekule’s patented PECO technology

Science at the nanoscale

Developed over 25 years 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.

The path to clean air

The path to clean air

1

360° air intake

Molekule takes in the surrounding air from every angle.
2

Particle capture

Air flows through high-efficiency outer filter layers, trapping large particles like dust and dander, and slowing down VOCs passing through the filter.
3

PECO process

Layers of a nanocatalyst-coated filter react to light, breaking down harmful pollutants into their basic components, leaving clean air in their place.
4

Clean air

Molekule releases harmless molecules that are meant to be in the air, reducing the presence of harmful pollutants.

Under the microscope — Black mould

PECO destroys pollutants at a microscopic scale, including VOCs and viruses 1000x smaller than what the HEPA filter standard 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.

The research and innovation behind our filter technology

The need for PECO’s pollutant destruction in the home has never been greater.

Molekule vs. RNA virus

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.
Molekule vs. DNA 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.
Molekule vs. Furniture off-gassing

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.
Molekule vs. Citrus-scented cleaner

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.
Molekule vs. Smoke (0.3-1 microns)

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.
Molekule vs. Dust (1-3 microns)

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.
Molekule vs. Pollen (3-10 microns)

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.

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.
