The air inside homes and offices is usually more polluted than outdoor air. And an excellent way to keep indoor air clean is to use an air purifier. If you’re in the market for a new air purifier, you might have heard of Molekule air purifiers. These cleaners use innovative technology to get rid of all kinds of indoor air pollutants. Read on to understand the technology and learn about some of the best-selling Molekule air purifier models. Technology All Molekule air purifiers are powered by the proprietary purification technology called Photo Electrochemical Oxidation, or PECO. This technology harnesses the power of free radicals to break down pollutants, such as different viruses, bacteria, mold, allergens, and chemicals, at a molecular level. Unlike other standard filters, PECO collects a vast range of indoor air pollutants and destroys them without releasing harmful ozone byproducts. Molekule also claims that PECO filters can kill contaminants 1000 times smaller than what the HEPA standard even tests for. Popular models Here are the most popular Molekule air purifiers: Air Mini and Air Mini+:  Both models are designed for small rooms up to 250 sq. ft. The difference lies in their features. The Air Mini+ comes with additional features, such as particle level indicator, auto-protect mode, and compatibility with iPad and iPhone.
