This is a shorter version one-piece replacement for older (pre 2004) Eco-Pur systems - this filter replaces both the outer filter and the inner filter.
IMPORTANT: These are three versions of this filter:
The Standard Version
The Longer, Narrow Version
The Shorter Version (this filter)
NOTE: This filter does not have minerals embedded in the filter media. Many of our customers use this filter alone as a direct replacement for their original two filters. If you prefer the mineral effect we recommend that you use this filter in conjunction with a SpaRX mineral cartridge, which lasts 4-6 months and is a very cost-effective solution.
