- MATRIKX CTO Carbon Block - 5 Micron
Kx Technologies MATRIKX brand carbon blocks are the most trusted and widely used carbon blocks in the world. The 10” size is the industry standard and will fit our systems, as well as virtually every brand of RO system that use similar looking carbon blocks and the 20" size works in our legacy BRS Spartan unit along with other 20" RO systems.
Most common filter arrangements
- If your system utilizes one carbon block we recommend installing the 5 Micron CTO in the second stage after your sediment filter.*
- If your system utilizes two carbon blocks, we recommend installing the 5 micron CTO in the second stage after your sediment filter and the 1 micron CTO Plus in the third stage.
Available in 10" and 20"
*You may use a 1 micron CTO PLUS in a single block arrangement, however, depending on pre-filtration and sediment content of your home's water, it may clog faster than you would like.

Improved taste of my water By Jay on 9/24/2014Jay would recommend this product to a friendI put an extra filter stage between my ro pressure tank and my kitchen faucet and use this filter in it. The carbon filter removes the taste of sulphur that my well water has in it, even after passing through the ro system.

Are these 4.5 or 2.5 " ?
How often, on average, do both of these filters need to be replaced?
Typically the filters will last between 6-9 months however the time may vary depending on water quality. to test, you can use a standard chlorine test strip to ensure chlorine is not getting through. Feel free to let us know if you have any further questions!
