When the Molekule Air purifier hit the market in 2017, it generated significant buzz with its sleek design and claims of revolutionary air cleaning technology called PECO (Photo Electrochemical Oxidation). However, as consumers increasingly search for the “best air purifiers for mold,” “are air purifiers a gimmick,” and “consumer reports on air purifiers,” it’s crucial to examine whether Molekule lives up to its hype.

Understanding PECO Technology

Molekule’s PECO technology is a modified version of photocatalytic oxidation (PCO), which has been used for decades to clean contaminated air and water. Unlike traditional HEPA filters that capture airborne particles, PECO claims to destroy pollutants at the molecular level, including volatile organic compounds (VOCs), viruses, bacteria, and mold spores.

The process works by coating filters with a nanocatalyst that reacts with UV-A light, creating hydroxyl radicals. These radicals then oxidize and break down captured pollutants into harmless substances. Molekule asserts that PECO is more efficient and effective than traditional PCO, allowing it to destroy pollutants without producing harmful byproducts.

Independent Testing and Consumer Reports

While Molekule’s claims sound promising, independent testing by reputable organizations has yielded mixed results. Consumer Reports, known for its rigorous testing standards, found that the Molekule Air and Air Pro performed poorly in removing particulate matter from a test chamber. Their assessment suggested that the tested model could only effectively clean a room of 100 square feet or less, significantly smaller than the advertised coverage area.

Similarly, Wirecutter, a product review site owned by The New York Times, dubbed the Molekule “the worst air purifier we’ve ever tested” based on its lackluster performance in particle reduction tests. Vacuum Wars, another independent reviewer, found that the Molekule actually increased dangerous VOC levels during testing, contrary to its claims.

These findings contradict Molekule’s assertions and raise concerns about the efficacy of their PECO technology in real-world settings.

Addressing Specific Pollutants

Despite the mixed reviews, Molekule has provided independent test reports demonstrating PECO’s effectiveness against certain pollutants:

Volatile Organic Compounds (VOCs): Intertek, a nationally recognized testing laboratory, confirmed that Molekule Air and Air Mini effectively reduced concentrations of formaldehyde, toluene, and limonene in a sealed chamber.

Mold and Bacteria: Testing by Aerosol Research and Engineering Labs (ARE) revealed that PECO technology successfully destroyed mold, bacteria, and viruses. However, it’s important to note that these tests were conducted on the PECO filter itself, not the complete air purifier unit.

Viruses: A peer-reviewed study by the University of Minnesota found that the Molekule Air Mini significantly inactivated concentrations of bovine, porcine, and H1N1 influenza viruses in a single-pass wind tunnel test. However, Molekule air purifiers have not been tested specifically on COVID-19.

While these targeted tests show promise, they do not necessarily translate to real-world performance in removing a broad range of pollutants from indoor air.

Pros and Cons of Molekule Air Purifiers

Like any product, Molekule air purifiers have their advantages and disadvantages:

Pros:

  • Sleek, minimalist design
  • Claimed ability to destroy pollutants at the molecular level
  • Independent testing shows effectiveness against specific pollutants
  • FDA clearance for medical use in destroying viruses and bacteria

Cons:

  • Mixed reviews from independent testing organizations
  • Relatively high cost compared to other air purifiers
  • Lack of transparency regarding filter composition and technology details
  • Potential for false advertising claims, leading to a $2.7 million class-action settlement

The Verdict: Approach with Caution

While Molekule’s PECO technology shows promise in addressing specific pollutants, the mixed reviews from independent testing organizations raise concerns about its real-world effectiveness as a whole-home air purification solution. Consumers should approach Molekule’s claims with caution and consider alternative options, such as HEPA filters or air purifiers recommended by reputable sources like Consumer Reports.

Ultimately, the decision to invest in a Molekule air purifier should be based on a careful evaluation of individual needs, budget, and a willingness to potentially sacrifice some performance for the sleek design and innovative technology claims.

As with any major purchase, it’s advisable to thoroughly research and compare various air purifier options, relying on independent testing and consumer reviews rather than marketing claims alone.
