Powered By Breakthrough IAMF Technology 

For over 21 years, IAMF advanced technology has been refined through extensive field and laboratory testing. This technology has the ability to reduce and remove up to 99.9% of aesthetics, chemical, dissolved solid and radiological contaminants as well as instantly boost pH up to 9.5. The filter is designed with a hard-porous coconut shell that is formed with absolute porosity and is filled with various proprietary media that has the ability to remove, absorb, adsorb, chemically bond, and chelate different contaminants.

The filter incorporates an extremely high-tech porous micro-filter system containing thousands of interconnected Omni-directional pores resulting in a "tortuous path." This "path" cannot be duplicated causing a tight maze for the water to travel through so that the water cannot channel. This gives the filter a uniform porosity and water flow. It is engineered from various polymers with controlled pore size. The design provides both filtering and structural strength.

The combined technologies of the filter using the IAMF system have been carefully designed to implement the most effective, strong, resilient, durable, long-lasting, and chemically resistant filter life available.

The filter is manufactured under ISO 9001 standards.

Before First Time Use

  1. Twist open the cap of the bottle and fill it with water. 
  2. Screw the cap back on, flip the top and squeeze the bottle 3 times to flush the filter.
  3. Draw purified water out from the straw.

Flush Prior to First Use

Your filter has been pre-flushed. However, we recommend you re-flush the filter before the first use. This will provide optimal water flow and ensure effectiveness.
