Your AIRBOX is designed to run 24/7 year-round. AIRBOX™ uses the highest quality fan in the world specific to this application. It is expected that we will only realize a 10% failure rate at 116,674 hours. That’s 13.3 years. We do a power draw test on every single AIRBOX™ before it leaves our Studio and find that they consume less than 60 watts of power in the energy efficiency zone while producing over 15,000 cubic feet of Pure Air every single hour of operation.. 60 watts is less than 20 cents per day for most of us.
