What is the difference of the Fridge and Sink systems?Updated 8 months ago

The only difference between our undersink and fridge line systems is the connections. 

The custom formulation and replacement cartridges will be the same. 

The undersink system comes with 3/8" connections, which is the universal standard for faucet connections, and the fridge line system comes with 1/4" connections, which is the universal standard for refrigerator lines.
