Molekule And Mila: Performance Comparison

Independent testing shows both Molekule and Mila effectively improve indoor air quality, but some differences emerge:

  • In Consumer Reports testing, the Molekule Air reduced airborne particles by 65% on high speed over 30 minutes. VOC removal was 46%.
  • The Mila Air Purifier scored very well in Allergy Buyers Club testing, removing 99.9% of smoke and dust in under 15 minutes on the highest setting.
  • Molekule appears effective at eliminating bacteria and viruses. In one study, it reduced E. coli bacteria by 99.99% and H1N1 virus by 99.98% in single-pass tests.
  • Mila claims its medical-grade HEPA filter removes 99.97% of particles down to 0.1 microns, including dust, dander, mold and bacteria.
  • For chemicals like VOCs, Molekule’s PECO technology probably has an edge over Mila’s activated carbon filter. Molekule’s catalytic reaction is tailored to break down these pollutants.

So while both can improve air quality in different ways, Molekule seems to have a performance advantage for destroying viruses, bacteria and gaseous chemicals. But Mila is no slouch either, excelling at particle removal.

How Do Molekule and Mila Work?

Both Molekule and Mila use multiple stages of filtration to clean the air, but their technology differs.

Molekule features a patented technology called Photo Electrochemical Oxidation (PECO). Air is drawn into the unit and first passes through a pre-filter that traps larger pollutants like dander, dust and pollen.

The air then moves to the PECO filter, which uses UV light to activate a catalytic reaction that breaks down pollutants at a molecular level. This destroys allergens, mold, bacteria, viruses and volatile organic compounds (VOCs).

Mila, on the other hand, uses a 3-stage filtration system. Air first goes through a mesh pre-filter that catches large particles. It then passes through a proprietary Sterling UM100 filter that uses an electrical charge to attract and trap smaller pollutants down to 0.1 microns.

Finally, activated carbon helps remove odors and chemical fumes. An additional UV-C light helps kill germs.

So while both purifiers use a multi-stage approach, Molekule claims an advantage with its PECO technology that doesn’t just collect pollutants but destroys them. Mila offers tried-and-true filtration methods but relies on users to change filters regularly.

Frequently Asked Questions (FAQ)

What is similar to Molekule?

Some comparable PECO technology purifiers like the Austin Air Healthmate and the IQAir HealthPro Plus also destroy pollutants at the molecular level. Other high-end HEPA purifiers like the Dyson Pure Cool and the Coway AP-1512HH Mighty offer similar performance and features.

Is Molekule Air FDA approved?

No, Molekule is not FDA approved. The FDA does not certify air purifiers like Molekule and Mila. However, both use filtration materials and technologies widely accepted as safe and effective. Molekule PECO filters have undergone independent laboratory testing for safety.

Does Mila detect mold?

Not exactly. The Mila air purifier senses overall air quality levels and types of particles, but does not specifically identify mold. Its sensors track particulate matter that could include mold spores. Frequent mold detection may indicate a moisture issue that requires further inspection.

Does Molekule destroy formaldehyde?

Yes, Molekule claims its PECO filters destroy formaldehyde as well as other VOCs and gaseous pollutants through oxidation at a molecular level. Independent lab results showed it reduced formaldehyde by 61% in 30 minutes. The PECO reaction converts formaldehyde into tiny amounts of water and CO2.
