The AquaHouse AH-CTO5 10-inch coconut shell carbon block filter is an ideal choice for homeowners and professionals looking to improve water quality in drinking systems, reverse osmosis units, and aquarium setups. This filter excels at removing chlorine, sediment, and organic impurities, ensuring cleaner, better-tasting water; however, users should note that it is designed specifically for standard 2.5-inch diameter housings and is not compatible with proprietary slimline or large-format systems.

No, this carbon block filter is designed primarily for chlorine, sediment, and organic compounds, not for fluoride removal.
The filter should be replaced every 12 months or sooner if you reach the 15,000-litre usage limit.
It will only work if your whole-house housing is a standard 10-inch by 2.5-inch size; many whole-house systems use larger 20-inch or 4.5-inch 'big blue' cartridges.
Yes, it is certified under the WQA Gold Seal program to meet NSF/ANSI 42 standards for safety and structural integrity.
No, this filter is intended for cold water use only. Hot water may damage the carbon media.
This is carbon dust. Flush the filter for 5-10 minutes until the water runs completely clear.
The filter may be saturated with sediment. Replace the cartridge if you have exceeded the 12-month lifespan or if water usage is extremely high.
Check that the O-ring is seated correctly in the groove and is not pinched or damaged. Apply a small amount of food-grade silicone grease to the O-ring if necessary.
Installation is straightforward due to the universal 10-inch standard sizing. To install, unscrew the filter housing, remove the exhausted cartridge, and clean the inside of the canister with mild soap and water before inserting the new AH-CTO5 unit. Always ensure the O-ring is properly seated before tightening the housing to prevent leaks. Note that you should flush the new filter with a few litres of water after installation to remove any residual carbon dust. The cartridge is compatible with all systems requiring a 2.5-inch wide by 10-inch long filter element.
