Frequently Asked Questions
-
What impurities does the RO-CTO-1 Carbon Cartridge remove?
The RO-CTO-1 carbon block cartridge removes chlorine, bad taste, odor, and organic contaminants. Its dense structure also helps trap fine particles, providing cleaner water before it reaches the RO membrane.
-
Is this a replacement cartridge for RO pre-filtration?
The RO-CTO-1 is designed for use in under-sink filtration and RO systems and is compatible with standard 10-inch prefilter housings which used before RO’s.
-
How often should I replace the RO-CTO-1 Carbon Cartridge?
It is recommended to replace the RO-CTO-1 cartridge every 6–12 months, depending on water quality and usage conditions.
-
How is a CTO cartridge different from a GAC filter?
A CTO cartridge uses compressed carbon (carbon block), which provides finer filtration and better chlorine removal compared to GAC filters that use loose carbon granules.
-
Do I still need a sediment filter before this?
Yes, a sediment filter is recommended before the CTO cartridge to remove larger particles and prevent clogging of the carbon block.
