Replacement Filters, in Closed Housing, without Box

4-piece filter set:
1. P20 – a sediment filter that retains particles larger than 20 microns. After mechanical impurities are removed from the water, it flows into the primary dechlorinating filter.
2. CP – a dechlorinating filter with an activated coconut-shell carbon insert that removes chlorine and chlorinated organic compounds – a byproduct of water chlorination – as well as various types of organic compounds. By capturing chlorine compounds, the primary dechlorinating filter protects the membrane's semi-permeable film from damage.
3. P5 – a sediment filter that retains particles larger than 1 micron.
4. CPP – an activated carbon filter filled with specially compressed activated carbon granules. The filter removes volatile substances and gases from the water. It improves the taste of the resulting reverse osmosis water.
