Unlike conventional humidifiers, the uniquely designed Arion is both consistent and convenient! The Arion relies on a proprietary special solution combined with hydrogels enclosed in space-age plastic, allowing moisture to consistently escape through its walls. The Arion humidifier also boasts carefree maintenance, since it requires only plain tap water refilled once every 1-3 months, making it easy to maintain increased levels of humidity in your case! Arion humidifiers will last many years and provide you with the security of knowing that your humidifier will not leak in your case.
