4-STAGE PORTABLE | WALL MOUNT RODI FILTER+/- 285LPD MEMBRANE FILTERS RO DI PURIFIER
PRODUCT CODE: PRO-4-D
Includes final stage post RO membrane mixed resin deionising [DI] filter
This system is assembled locally in our QLD factory using high quality approved parts
This item is sent with connectors to fit 3/4" and 1/2" garden taps [per image 7 and measure 25mm and 20mm respectively] as well a sink mixer diverter [per image 8] to fit most standard* sink mixer taps
*Standard mixer taps refer to a mixer tap where you can unscrew the aerator on the end of the tap and will be left with either a 20mm female thread or a 23mm male thread. If you have the 20mm female thread you`ll need to use the inside to outside thread converter [in the 3rd picture and supplied with this item] to connect but if you have a 23mm male thread after removing the aerator you won`t need to use the thread converter
Easy to carry around or wall mountable and great for producing pure H2O for topping or filling up fish tanks
The reverse osmosis process results in the purest possible water and results in the total dissolved solids (TDS) count dropping by +/- 96% depending on environmental factors
As this system also has a final stage mixed resin deioniser after the reverse osmosis membrane the removal rate increases to between 99.9%-100%
This purification process is commonly considered to be the most effective method of purification available to the public, and will consistently produce the lowest level of contaminant
RO will reduce/remove all of contaminant in the feed water including chlorine, fluoride, volatile organic compounds, disinfection by-products, heavy metals, etc
See below table for effective reduction of common contaminants:
| ELEMENT/COMPOUND | % REDUCTION | ELEMENT/COMPOUND | % REDUCTION |
| Barium | 99.99% | Potassium | 100% |
| Bicarbonate | 100% | Radium | 99.99% |
| Cadmium | 99.99% | Selenium | 99.99% |
| Calcium (Hardness) | 99.99% | Silicate | 99.99% |
| Chromate | 99.99% | Silver | 99.99% |
| Copper | 99.99% | Sodium | 99.99% |
| Detergents | 99.99% | Strontium | 99.99% |
| Fluoride | 100% | Sulphate | 100% |
| Lead | 99.99% | PCB’s | 99.9979% |
| Magnesium | 100% | Insecticides | 99.99% |
| Nickel | 99.99% | Herbicides | 99.99% |
All of the parts that come into contact with the water in our systems are manufactured from BPA free food grade plastics. All of the filters and parts that we use when assembling your system have NSF INTERNATIONAL (National Sanitation Foundation), WQA (Water Quality Association) or FDA (Food and Drug Administration) quality standard certification.

*Where the feed water TDS reading is high, the minimum operating pressure of the unit may be affected. If your feed water TDS is in excess of 400ppm we recommend that you consult us before you purchase. Generally these systems are suited to most town mains water supplies, however if you are intending to use the unit on tank or bore water we recommend testing the feed pressure and water quality first.
