First Stage Filter 

10BDGD-PA dual gradient filter which is manufactured from 100% pure polypropylene. It is designed to remove sediment, and particles and for cyst reduction. Using an advanced design the filter is able to achieve up to three times the normal dirt holding capacity as other sediment filters. It has a 25-micron outer shell for larger particles and a 1-micron inner shell for finer particles and cysts. Effectively you are getting two filters in one.

Second Stage Filter

KDF-GAC filter is a two-media cartridge consisting of KDF (high purity copper-zinc alloy) and GAC (granulated activated carbon). Through the electrolytic and oxidation reactions of the KDF and the adsorption and entrapment capabilities of the GAC, the KDF-GAC filter can remove or greatly reduce a wide range of contaminants.
