Product Description
Replacement Water Filter Cartridges
Our top quality "Master Purifier" Universal cartridge can be fitted to many other makes of water filters, including:
Brands like: Cuno... Ametek ... Liff ... Plymouth ... Bruner ... Noga... Pentek... Homebase... Screwfix... and many Other brands including reverse osmosis pre filters.
This top quality filter will replace any cartridge types that are 9 and three quarter inches length x 3 inches or less diameter. With a 1 inch aperture at either end.
If your existing filter looks anything like this it can probably be replaced by our specially made cartridge. See why below.
Firstly: in the bad old days water filters would come in all shapes and sizes. The aim was to force customers to return to particular manufacturers.
However in recent years there has been a growing move to standardise the sizes of filter cartridges. Now about 80% of all cartridges are the "universal ten inch size".
(Note: Why they are called "ten inch" is a mystery as they are actually 9 and three quarter inches high!)
Secondly: the great majority of water filters are made from carbon.
And the great majority of carbon filters basically consist of burnt coconut shell.
It is a question of exactly how it is moulded into the required filter shape during the filter manufacturing process.
For example, the carbon might be cut into grains and placed inside a hard cartridge case (Granular Activated Carbon / AC).
Or they might be compressed into Carbon Block and typically be surrounded by a mesh - as is the case with our specially made "10 inch" types - see above right.
While Carbon Block is now generally seen as being a superior method of filtration over GAC, they basically do the same job.
The point is that as long as the size of the cartridge is correct, one type can be changed for the other.
Micron Size of the Water Filters
The other thing to look for in any water filter is what micron size the cartridge filters down to.
A micron is a millionth of a meter, so 100 microns is a tenth of a millimetre.
A human hair is about 75 microns in diameter.
Our filter cartridge is a top quality carbon block cartridge that filters down to 5 microns.
Five micron cartridges are the standard size for good quality domestic water filters.
It is very likely that your existing cartridge is 5 microns - assuming it is not there to filter out something very specific.
The next size down from 5 is 1 micron. This is fairly unusual so if you know that your filter is 1 micron you would need to check if there is any specific reason for that.
It might be that it simply sounded good at the time to whoever bought the filter. Volume 11 must be better than volume 10, and all that...
But perhaps it is supposed to stop a specific contaminant like bacteria.
Now the best way to filter out bacteria is using filtration methods such as Reverse Osmosis or a combination of approaches – so 1 micron is not necessarily the best solution for that anyway.
The best way to determine if the standard 5 micron filter is right for you is to check on the following:
Do you have a private water supply? If you aren't on the normal mains / municipal supply then you might need special filtration – and even a 1 micron carbon cartridge might not be the best thing. (Click here to see solutions to specific drinking water problems).
Do you have another special water supply situation / needs – for example you might have lead pipes… or a special health condition?
If so, unless you are looking to replace reverse osmosis 10 inch pre filters (if so, good: we can help you. our "ten inch" filters will do the job) – this might be a good time to review what the best water filter solution would be for you.

This height includes the rubber seals at both ends. They have a 1 inch hole at either end, in the middle, to slot into the housing unit. Their diameter is approx 66mm. However they can replace cartridges with similar diameters. The main thing is to make sure that the height is correct and they have a 1 inch hole at either end, in the middle, to slot into the housing unit.
