Why do some filters have a blue/pink/black stem saver?
We’re excited to announce an upgrade to our Foundation Filters: transitioning from the original blue stem savers to a new, integrated black stem saver design. Unlike the previous version, was attached to the Foundation Filters with a food grade adhesive, the new stem savers are precision molded directly into the filter. This streamlined, one-piece construction enhances product durability and reduces the need for adhesives. The result is a stronger, more reliable filter that meets our highest standards for performance and quality. The filters with a pink stem saver are only available for the states of California and Iowa.
