Air Purification Cartridge
Many fresh foods emit ethylene gas, a naturally-occurring compound that hastens food ripening and spoilage. Sub-Zero refrigerators come with an air purification system (based on technology developed by NASA) that scrubs the air of ethylene and odor every 20 minutes. The cartridge is designed to last up to one year!
