Working Temperature
39.2°F to 125°F
4°C to 52°C
Designed to reduce lead, volatile organic compounds, cyst, chlorine, taste, odor and sediments
These filter cartridges are designed to perform at high flow rates with a low pressure drop. They have a high adsorptive capability and dirt holding capacity with shorter flush time to efficiently reduce lead and other contaminants from water. The cartridges are available in 10 and 20 inch lengths with a nominal filtration rate at 0.5 micron.

Carbon block cartridges with lead reduction are ideal for a wide range of residential, food service, commercial, and industrial applications.

Performance and capacity claims are based on independent and internal testing, and upon the filter cartridge being integrated with a complete system (i.e. filter, housing, fittings, tubing) connected to a regulated pressurized water source.
The system must be operated according to system installation and operation manual, for proper installation and proper filter cartridge replacement process. It is essential to follow operational, maintenance and filter replacement procedures to ensure proper filter cartridge performance.
The cartridge capacity may vary upon the of the inlet water conditions and according to flow rate and inlet line pressure, which may require more frequent filter cartridge replacement.
The contaminants and substances reduced by this filter cartridge are not necessarily in user's water.
Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before and after the system.
To start, flush the system for five (5) minutes before use.
