 * = All membranes supplied are TFC with the film being USA made | ** = uM is our abbreviation for micron rating

Notes: [1] Standard volume filters [per image 2] will effectively remove chlorine to protect the RO membrane to a maximum of +/- 10,000 litres [includes pure and waste water] whereas high volume water filters will do so for a maximum of +/- 30,000 litres [we currently supply Matrikx USA CTO as the high volume filters per image 3]. [2] Silver infused anti-bacterial filter has changed to one in image 5 which performs the same function and brand of filters and membranes may vary between equivalent brands depending on stock levels. [3] RON is a unit without a pump and ROP is a unit with a pump and the filter packs are the same for both.

Pictures 1-10 are included in this listing depending on your drop down menu selection but pictures 11 and 12 are not and are included to display the types of reverse osmosis systems these filter packs are used with.

These filter kits are applicable to reverse osmosis systems permanently installed to town mains water supply

The actual measurements of these 10"x2.5" filters are L = +/- 25cm x Diameter = +/- 7cm with an inner core hole of +/- 2.5cm
