Filteroo® 8” Rain & City Water Carbon Block Gravity Water Filter Cartridge
Quality Water Filtration with the Minerals Retained
This is a carbon block cartridge suitable for use in any gravity water filter. It is 8 inches high x 2 inches wide in diameter. It is manufactured for the Filteroo® Steel gravity water filters, but it is also the perfect solution for any other brand that is used to filter rainwater from a water tank or treated city tap water.
It is a great choice with a standard 0.49 inches threaded end to install into any gravity water filter,, so long as the gravity water filter top tank has a minimum hole size of 0.49 inches or a maximum hole size around 0.79 inches. (Note: You can drill or file the hole in your water filter top tank to be 0.49 inches if required.)
It flows at a much faster flow rate than the ceramic gravity candles, it has fantastic test results, and it creates contaminant-free, healthy, tasty water.
If you are filtering rainwater, 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 rainwater is, but rainwater 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 that have both aesthetic and health concerns.
This cartridge has a smooth outer shell compressed to repel any sediments, cysts, bugs, or bacteria. The carbon's pore structure allows for ample contact time, making this cartridge perfect for enhancing taste and odor.
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 US, who guarantee that high-quality materials are always used. This single carbon block gravity cartridge is a highly efficient filter suitable for removing unwanted contaminants from any water supply. It is great for both rainwater and 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 528 gallons.
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 been blocked with fine sediments. These sediments do build up and can slow the flow rate over time, dependent 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 Scotch-Brite 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 0.264 gallon of water be allowed to flow through the cartridge to waste before using.
