Molekule Air is in a class by itself. It uses Photo Electrochemical Oxidation (PECO) nanotechnology to destroy viruses, VOCs, allergens, bacteria and mould. The easy-to-control touch-screen interface connects to your WiFi and you can control it remotely using the iPhone or Android app. It's whisper quiet, too! The 41-decibel Silent Mode is sonically unobtrusive. More than $1.2K new!
