Via a special silver-infused filter and specially designed diffuser, The JML Chillmax Air Pure Chill turns water into a fine mist of cool, refreshing air circulated by a fan with three-speed settings. It humidifies while it cools your personal breathing space so you can stay cool and breathe moist, humid air wherever the weather is hot and muggy day or night. The secret is Hydro-Chill Technology, which uses an advanced, silver-infused evaporative air-cooling filter and enhanced cool-mist diffuser, to pull in warm, dry air and instantly transform it into a cool refreshing mist. It uses just ordinary water and lasts for hours on just one filling! Simply fill the convenient top-fill reservoir, plug it in and enjoy! Plus, It also has a built-in soft-glow LED light with seven colours to choose from, so it’s the perfect night light for those hot, muggy nights.
