These are the replacement filters for the Pure Blue (PB) 2-stage drinking water system. It is recommended that these filters be changed out every year to ensure the highest quality filtration.
The PB 2-stage standard configuration comes with two PB Standard 12 inch carbon filters. If you are looking for the PB 2-stage standard with 8 inch filters, they can be found here.
Important Note: These filters are NOT compatible with the Ultra drinking water system. If your system has the word "Ultra" printed on it, and your filters are white, these are NOT the correct filters. Your filters can be found here.
