4 Stage Compact RO Replacement Water Filters & 180g DI Resin
Finerfilters 4 Stage Compact Aquarium Reverse Osmosis Replacement Water Filters
Replacement packs contain;
1 x Sediment Pre-Filter
1 x Post Carbon Filter
1 x Bag of DI Resin (~180g)
Optional: 1 x Vontron 1812/2012 Membrane (select capacity)
If you select the "No Membrane" option then you will receive only the sediment and carbon filters.
Please note: The sediment and carbon filters have threaded 1/4" Female ports.
These replacement packs are for filters and membrane only. Fittings are not included.
If you are replacing filters on an existing Finerfilters compact RO system then you will need to unscrew the elbow fittings currently connected to your filters.
PTFE tape will be required when installing fittings.

Filter Specifications
PP 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.
T33 Activated Carbon Post-Filter
Removes any residual impurities and "polishes" the water.
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.
| Model | Membrane Surface Area | Avg. Permeate Flow | Stable Rejection Rate | Minimum Rejection Rate |
| ULP1812-50 | 4.4ft² / 0.41m² | 50GPD / 0.19m³/d | 97.5% | 96.0% |
| ULP1812-75 | 5.0ft² / 0.46m² | 75GPD / 0.28m³/d | 97.5% | 96.0% |
| ULP1812-100 | 6.0ft² / 0.56m² | 100GPD / 0.38m³/d | 95.0% | 93.0% |
Please Note: Membrane performance is dictated by several variables, most importantly are; incoming water TDS levels, pressure, and temperature. The statistics 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
