Single bathroom homes typically have lower water flows and use than homes with two bathrooms.
A single shower typically uses around 10 to 12 litres per minute which is the rated flow of most 10 inch Jumbo cartridges. Although a 10 inch cartridge is commonly used in homes with low use, we do prefer to supply 20 inch jumbo systems where 3 or more people are in the home as the water flow performance is better and the cartridges lasts longer. With double the cartridge size you can run a shower and turn on another tap and still have high removal and flow capacity from the cartridges.
It is recommended to use a sediment cartridge prior to the carbon cartridge to prevent the carbon cartridge from clogging with dirt. This is also recommended with the larger 20 inch cartridges but not as essential as it takes longer for the larger cartridge to clog.
We typically recommend using 5 micron Activated Carbon cartridges as they provide good filtration and water flows and will not slow down the water flow as finer 1 and 0.5 micron cartridges will. With a 1 micron sediment cartridge in front of the carbon filter , the carbon filter will stay clean and can work at maximum efficiency to remove the chemicals and chlorine.

Twin 20 inch Jumbo
Standard cartridges are Activated carbon. The option of adding KDF media will also reduce heavy metals such as lead.
A pressure limiting valve is essential to protect the filter casings from cracking under high pressure. Most newer homes have one fitted but older homes may not. Please either order one with the kit or ensure you plumber checks to see if one is required during installation.
Wall Brackets - Standard or Stainless?
The smaller 10 inch system comes standard with a stainless steel wall bracket. The larger 20 inch systems have the option of powder coated steel brackets for indoor installation or Stainless Steel for outdoor installation.
Powder Coated steel is fine for indoords but Stainless Steel will not rust if outdooors.
Triple Filter Systems
For triple filter systems as in the pictures, pleae refer to the section for medium sized homes
