As all the coffee lover or anyone who work at the coffee industry, We all know the coffee have coffee powder and coffee bean, and after roasted the coffee, some of you maybe pack them directly, but some of us will grind the coffee as the coffee powder or we call ground coffee.
That is why we need to use the one way valve with filter. The ground coffee will be pack by the one way valve with filter, that can prevent the ground coffee getting into the coffee valve which maybe effect the function of the one way coffee valve.
If you still have question about the coffee valve with filter or without filter, feel free to contact with us to get more information.
