Coralife Pure Flo II Reverse Osmosis Carbon Block Pre-Filter Cartridge, 2.7" L X 2.7" W X 10" H

Solid Carbon Block used to filter water and remove chlorine before reaching the RO membrane. Positioned between micron cartridge and the TFC membrane. Can also reduce levels of some soluble & volatile organic compounds.

Fits most Mixed Bed Deionization Reverse Osmosis Canisters including the Coralife Pure-Flo 1 & 2 Models. Replacement Carbon Block for the Coralife Pure-Flo Reverse Osmosis systems. The units remove hardness, heavy metals, toxins and many other toxins, leaving clear and polished water for maximum clarity. Unit filters water before it reaches the R/O membrane. Improves the functional life of your TFC membrane.

Chlorine and chloramines will damage your R/O membrane and the use of a carbon pre-filter can thus improve its functional life. This filter should be positioned between the micron cartridge and the TFC membrane. Additionally, these carbon pre-filters also reduce the levels of some SOCs (soluble organic compounds) like pesticides, dioxins and VOCs (volatile organic compounds like chloroform and petrochemicals). Maintenance/Lifespan: Carbon pre-filters should be replaced every 3,000 gallons or 6 months (whichever occurs first). Depending on the quality of your water source, you may need to replace these pre-filters as often as once per month. If not replaced - certain elements (such as chlorine) will become present in your purified water and your membrane cartridge will also become damaged.
