This is a set of Platinum Pure Standard and Plus filters for the Ultra Pur RO system. It is recommended that these filters be changed out every year to ensure the highest quality filtration.
These filters are the replacement for the discontinued Ultra Pur Pre/Post RO filters (UPF 12 PRE, UPF 12 POST).
Important note: These are NOT the replacement filters for the Pur Blue (PB) reverse osmosis drinking water system. If your filters are blue, your replacements can be found here.
