Finerfilters 4 Stage Triple Aquarium Reverse Osmosis with DI Resin For Drop-In Cartridge Replacement Water Filters
These filters also fit the Dental Surgery RODI Pure Water Filter System
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 bag x 2
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
