Molekule Air Minis two-in-one PECO-Filter traps large particles and destroys pollutants at a molecular level. Air gets circulated through the outer layers, trapping larger allergens like dust and dander, and slowing down VOCs on their way to the PECO-Filter. There, a chemical reaction occurs when a nanoparticle-coated filter is activated by light, breaking down harmful pollutants to their most basic molecular components.
