KX Matrix 32-425-125-20 +CTO 2 Carbon Block Hey everyone, Tony the Filter Doctor here.
Today we’re looking at the KX Matrix 32-425-125-20. It’s better known as the +CTO/2.
Now, the +CTO/2 is an industry standard size cartridge, approximately 20 inches in length
and 4 ½ inches in diameter, which means it’s going to fit into a vast selection of industry
standard size filter housings, like for example the one that you see here.
Now, the +CTO/2 is a 5 micron carbon block manufactured by KX Matrix in the good old
USA, and this is their no frills version. This does not have any special certifications
for really nasty contaminants. It’s just a basic 5 micron carbon block designed for
chlorine taste and odor reduction and generally making the water more palatable.
If you’ve got a VOC problem or a turbidity problem or microbial cysts then you need to
look to some of the other KX Matrix carbon blocks that are available.
The +CTO/2 is very popular in industrial and commercial reverse osmosis systems as the
polishing filter just before the water hits the reverse osmosis membrane. It’s great
for removing the chlorine that would otherwise be harmful to those membranes.
Now, filter life is approximately 26,000 gallons for chlorine taste and odor, but beware, it
is 5 microns so it’s a very tight filter, if you have a sediment issue, you need to
pre-filter before the water gets here or you could potentially clog this filter long before
the carbon is truly exhausted. And that would be a waste of really good carbon. So make
sure you have some kind of pre-filtration. Again, this is the KX Matrix 32-425-125-20,
better known as the +CTO/2, their no frills 5 micron carbon block.
I’m your host Tony the Filter Doctor. Thanks for watching.
