The selection of water filter cartridges we have is extensive, but the cartridges listed here are not all that we stock. 

The most important thing when it comes to replacement water filter cartridges is the size. The most common size is what is referred to as a 10 inch standard, but these are not 10 inches long, but 9-3/4 inches long and in general 2.5” to 3” in diameter. The metric measurement is 248mm x 65-75mm. This size is referred to in the industry as 10 inch standard and is the most widely available cartridge, but there are other sizes and configurations in the water filter industry.

There are many companies that produce housings that take a cartridge that is slightly different in some way such as length. They will promote the cartridge as being the best but in reality they are produced to stop you shopping around and once you have purchased the system you are trapped to dealing with that supplier. They even go as far as supplying these non standard systems for free to Builders knowing they will sting you when a replacement cartridge is required. If you have such a system, give us a call as we will most likely be able to convert your system to take a standard size cartridge.

By far the most common sediment filter is the polyspun sediment filter. This type of cartridge performs very well and is reasonably priced. Also available are the pleated sediment filter cartridges. The pleated sediment cartridges cost a bit more, have a higher flow rate with a lower pressure drop and are cleanable, but block sooner than a polyspun. So in general, even though they are cleanable, they don’t usually outlast a polyspun.

Carbon Cartridges are also called chemical filters as these cartridges are the work horse in a filter system. Carbon based cartridges treat for colour, taste and odour and remove things like chlorine, pesticides, herbicides and many other types of chemicals with some also rated to remove heavy metals. We sell many brands and in general don’t promote one brand over another. We have the specification sheets for them for you to download and choose one that you like. If you require some guidance please don’t hesitate to call us on 1800 305 579 and we will assist you by giving the strengths of each cartridge type and brand.

In-line filters, such as the Omnipure range vary from sediment filters through to carbon filters that are cyst and heavy metals rated. These in-line filter uses are common installations for post filtration on reverse osmosis systems and fridge filters.
