Introducing Airgone, a pressurized Argon gas can. Argon is a non-reactive, odorless, tasteless, food-safe gas heavier than oxygen. With just a 2-second flush of Airgone (good for 75 flushes), you can prevent freshness degradation by creating a barrier between your stored goods and excess oxygen. Displaced Oxygen releases through the degassing valve of the Fresh-Port products, in addition to naturally releasing C02 buildup. We cannot ship AIRGONE to PO Box addresses, Alaska, Hawaii or Internationally (Excluding Most Canadian Providences). All AIRGONE products will be shipped via UPS.
