FRIIS Coffee Savor Valve Set
The patented Freshness Valve is the key to eliminating trapped CO gas. The integrity of the one way valve deteriorates with time, to ensure optimal performance you should replace every 2 months. The valve is constructed with a unique filter that allows carbon dioxide gas to pass through without allowing oxygen or other gases back in. This one-way valve removes the trapped gas that breaks down and destroys coffee flavor over time.
We suggest replacing your Freshness Valve every two months. To help remind you, we've added a helpful date wheel to the top of your Friis Coffee Vault. This rotating wheel is designed to help you set a monthly reminder to replace your valve on the appropriate day. Using your finger and thumb, move the date wheel to expose a numbered day.
