Baking soda label acts as a freshness timer

Special label eliminates replacement guesswork for a refrigerator air filter.

Pw 8664 Web Arm

WS Packaging Group (www.wspackaging.com) has solved a long-standing consumer conundrum of knowing when to replace the Arm & Hammer brand Baking Soda refrigerator air filter.

The “replacement indicator” was developed exclusively for the New FridgeFresh™ Refrigerator Air Filter. The consumer activates the label my removing a middle overlay via a pull tab. The white bar on the label turns pink as time passes. When it is completely pink, there’s no guessing about when it’s time to replace the air filter.
