Filteroo 8” Rain & City Water Gravity Carbon Block Filter Cartridge
Quality water filtration with the minerals Retained
This is a carbon block cartridge suitable to be used in any gravity water filter it will fit inside. It comes with 2 x cartridges, priming washer and instructions. It is 200mm high x 60mm wide in diameter. It is manufactured for the Filteroo Steel gravity water filters, but it is also the perfect solution for any other brand which is used to filter rain water from a water tank or treated city tap water.
It is a great choice with a standard 12.5mm threaded end to install into any gravity water filter so long as the gravity water filter top tank has a minimum hole size of 12.5mm or a maximum hole size around 20mm. (Note: You can drill or file the hole in your water filter top tank to be 12.5mm if required.)
It flows at a much faster flow rate than the ceramic gravity candles, it has fantastic test results and creates contaminant free healthy tasty water.
If you are filtering rain water, it is great as it will stop all the bugs & bacteria in the water, whilst at the same time it protects you from any herbicides, pesticides or lead that may wash in from your roof. You will hear people say how lovely their rain water is, but rain water tastes even better once it has filtered through a good big block of carbon like this.
Then for treated city water, you have the same great protection from bugs & bacteria, it has super high removal rates for the common contaminants like chlorine & chlorine by-products, plus it will protect you from any herbicides & pesticides or heavy metals that may be in the water.
This Filteroo rain & city water carbon block gravity water filtration cartridge is made from the highest quality carbon. It combines mechanical filtration and physical adsorption processes to reduce a wide variety of drinking water contaminants of both aesthetic and health concerns.
This cartridge has a smooth outer shell compressed to repel any sediments, cysts, bugs or bacteria. The pore structure of the carbon enables sufficient contact time for this cartridge to be ideally suited to improving taste and odour.
You will be battling to find a better carbon block gravity cartridge than this, that’s a fact.
What Makes This Product Unique
It is the quality of the carbon used to create the carbon block cartridge and the professional manner in which they are manufactured which has passed all the tests at such high removal rates that makes this cartridge so unique. As the water passes through this cartridge slowly, the contact time with the cartridge allows for such a wide range of contaminant removal. Manufactured for Filteroo Australia who guarantee high-quality materials are always used. This single carbon block gravity cartridge is a highly efficient filter suitable to remove unwanted contaminants from any water supply. It is great for both rain water or chemically treated city water.
If you would like to remove Fluoride as well, you can simply attach the Filteroo Max Fluoride removal cartridge onto the bottom thread of the carbon cartridge.

Long-Lasting Service Life Of 12 Months
Cartridges are very easy to replace and only have to be changed over as required or every 12 months, whichever comes first. They have a recommended maximum life of 3000 litres.
Due to the filtration of particulate & sediments from the water during use, the flow of water from the filter may reduce over a period of time.
If your cartridge water flow rate slows down it is normally only because the outside of the cartridge has blocked with fine sediments. These sediments do build up and can slow the flow rate over time dependant on the volume of sediments in the water supply used to fill the top tank.
To restore the water flow to its normal level, simply remove the cartridge and follow the backwashing instructions to backwash the cartridge and push sediments back out of the cartridge.
If after backwashing the water flow is still slow, you can also get some 100 grit sandpaper or a new Skotchbrite scour pad & scrub the outside of the cartridge under a flowing tap, ensuring that the open-ended thread does not contact the water to avoid contamination. Scrub harshly as this cartridge is quite thick & can be scrubbed clean many times.
Cleanliness is important, wash your hands before handling the cartridge and take care to ensure that no contamination of the cartridge occurs during cleaning. Use a glove or similar so your hands don't touch the cartridge as much as possible.
NEVER WASH WITH DETERGENTS OR SECOND-HAND SCOURER PADS.
If the filter is left to stand for more than 3 - 4 days without use, it is recommended that one litre of water be allowed to flow through the cartridge to waste before using.
When installing or replacing any water filtration cartridges, ensure you know what you are doing or have a qualified person to help you or contact us for assistance. Please find paper instructions inside every cartridge box.
- Cleanliness is important. Wash hands before handling the cartridge and take care to ensure that no contamination of the cartridge occurs during assembly.
- Pre prime the cartridge as instructed in the priming instructions.
- Use a glove or similar so your hands don't touch the cartridge as much as possible.
- Remove the locking nut & leave the sealing washer over the threaded stem.
- Place the filter candle thread through the hole in the upper section of the top housing from the inside out and secure it with the wing nut.
- Do not overtighten.
- Ensure that the outlet tap is in the off position.
- Fill the upper chamber with cold water and allow this to filter down through to the lower section.
- It is recommended that this first supply of filtered water is thrown away, as it may contain material washed from the filter element.
- Some black carbon fines may be seen when first using but this is harmless & will stop fast.
- Fill the upper chamber again, open the outlet tap and allow this water to run to waste again.
- We recommend flowing at least 12 litres of water through the cartridge to waste until it is tasty and flowing clear.
- If you are using the mineral pad, rinse that under water for 5 seconds to remove any media fines & sit the pad on the inside base of your Filteroo Steel.
The filter is now ready for use.
Fully Disposable Cartridges
You can break up the old cartridges with a hammer into small pieces and put the crushed carbon into the garden, then place the plastic end caps into the recycling bin. Or, simply wrap your worn-out cartridges up in old newspaper and place them into your rubbish bin.
