Do not use the 20″ Pure Coconut Carbon filter for drinking water with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Filters are designed to fit most standard household and commercial or industrial housings. Performance claims are based on independent lab results and manufacturer’s internal test data. Actual results obtained will vary with various combinations of organic contaminants, changes in pH or other conditions encountered in actual use. All information presented here is based on data believed to be reliable. It is offered for evaluation and verification but is not to be considered a warranty of any kind. Flush new cartridges until water runs clear prior to use.

Change filter at end of life or every 12 months.  Whichever is first.
