20-Inch CTO Filter for Professional or Industrial RO Systems
Filters
Description
This pre-filter is made of activated carbon blocks that trap impurities such as chlorine, organic contaminants, pesticides, and other chemicals that affect the smell and taste of water. It measures 50.8 cm in length and 7cm in diameter.
Maintenance
We recommend changing the CTO filter every 3 months on an industrial RO system that runs continuously, or every 6 to 12 months on a professional RO system, depending on how often you use it. It's very easy; simply turn off the unit, unscrew the housing, replace the filter, and screw the housing back on. It only takes a minute!
