pollutants being destroyed by Molekule PECO filter element

PECO technology by Molekule—Destroys SARS-CoV-2 & more.

Proven by science

How do Molekule air purifiers work? Developed over 25 years by research scientists, PECO is an innovative technology that uses free radicals—the same radicals used to destroy cancer cells—to break down pollutants at a molecular level, including viruses, bacteria, mold, ozone, allergens, and chemicals. By combining PECO nanotechnology with HEPA filtration and air quality sensors, Molekule air purifiers can capture particles found in smoke, while detecting and destroying organic pollutants like bacteria, viruses, chemicals, mold, allergens, and more.

Molekule’s PECO air filter destroys over 99% of SARS-CoV-2 in 1 hour.

New research shows Molekule Air Mini removed 99.98% of the SARS-CoV-2 virus from the air in a one-time release multiple pass test in a small chamber, PECO destroyed over 99% in a filter swatch level test in under one hour.*

These results build on past research with viral capture and destruction and demonstrate how PECO adds a layer of protection against airborne viruses.

The path to clean air, now with advanced sensing

The path to clean air, now with advanced sensing

1

360° air intake

Molekule Air Mini+ takes in the surrounding air from every angle.
2

Particle capture

Air flows through outer filter layers, trapping large particles like dust and dander.
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

The PECO-HEPA Tri-Power filter boasts not one, but three layers of protection. It combines true HEPA 99.97% particle-capture efficiency rate with Molekule’s very own patented PECO technology that destroys organic pollutants like viruses, bacteria, mold, allergens, volatile organic compounds, chemicals, and more. The powerful, triple-layered filter is finished with a final layer of carbon filtration to reduce odors and toxic gases, delivering clean, crisp air.

Air Mini+ vs. SARS-CoV-2

SARS-CoV-2 virus. More than 99% viral reduction in under one hour.*

SARS-CoV-2 has caused a global pandemic and spreads through the air. Infection and severity is associated with exposure to a high viral load. Air Mini+ was able to reduce the concentration in the air by 99.98% and destroyed 99% of the virus on the catalyst in one hour.

Testing location and standard

Tested at University of Nebraska Medical Center, Department of Pharmacology & Experimental Neuroscience

*Pollutants were not re-released into the chamber after initial introduction. Device operated on the lowest speed setting. No air purifier can prevent you from getting a virus. Molekule encourages the use of PPE and medical countermeasures suggested by government authorities.
Air Pro vs. RNA virus

RNA virus MS2: 99.99% removed in 30 min*

Air Pro can help remove airborne viruses like MS2 bacteriophage, a proxy virus for SARS-CoV-2, both of which travel in tiny droplets that can linger for hours before settling on surfaces.

Test location & 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.
Air Pro vs. Citrus fragrance

D-limonene: undetectable in 2 hrs*

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