Preserve and protect coffee beans or other food products with Airscape preservation technology, using the Airscape Bucket Insert. This lid uses the patented Airscape design, and suits any 3-7 gallon bucket (not included). The Airscape Bucket Insert not only forces the air out and keeps the freshness in, but is also moisture and pest resistant. It features an Integrated Fresh-port, which allows bucket contents to be flushed with gas to preserve the life of the goods inside. The Airscape Bucket Insert is suitable for storing roasted or green coffee beans, flour, rice, legumes, and other dry kitchen goods, as well as pet food, birdseed, and feed. It can also be used as an under-counter compost bucket lid to keep flies and smells away. Additionally, it can be used for pickling and fermenting. The insert is 100% BPA-Free and fits most standard 5-gallon buckets, or any bucket with an 11.9 inch diameter.
