Finerfilters 4 Stage Drop-In Aquarium Reverse Osmosis Replacement Water Filters
Filter Specifications
10" Drop-In Sediment Pre-Filter
Removes impurities in water such as sand, dirt, rust, silt, and suspended solids down to 5 Micron in order to protect the RO membrane.
10" Drop-In CTO Activated Carbon Block Filter
Removes chlorine taste and odour as well as THMs and other organic chemical compounds.
This CTO filter will not remove chloramines.
DI Resin (180g bag)
The deionising resin will attract any charged ions left in the water after it has passed through the Reverse Osmosis membrane, ensuring that you achieve a TDS reading of 0 required for most aquarium water top-ups. The resin we supply with this pack is Tulsion MB115 Mixed Bed DI Resin.
RO Membrane
The semi-permeable membrane removes impurities in water down to 0.0001 Micron including (but not limited to); bacteria, viruses, heavy metals, hormones, PFAs, etc.

Please Note: Membrane performance is dictated by several variables, most importantly are; incoming water TDS levels, pressure, and temperature. The membrane outputs stated above are based on test conditions which are;
Concentration of Solution (NaCl) = 250ppm
Water Pressure = 60 psi / 0.41MPa / 4.14 Bar
Temperature = 25°C
The membrane elements must be stored in a cool and dry place, away from direct sunlight. Do not expose to temperatures above 45°C
