3i Water Purification System


The 3i delivers glass after glass of pure drinking water at the touch of a button while keeping our world and your workplace healthy.

PHSI Pure Water Technology’s newest system eliminates the environmental and workplace impact of bottled water systems while supplying FRESH, HEALTHY and PURE drinking water at the point-of-use.


Reverse Osmosis Filtration

80 Gallon per day “green” reverse osmosis filtration system removes contaminants including Total Dissolved Solids (TDS). Leaving you with pure drinking water that is free of dirt, chemicals, metals, etc.

Activated Oxygen Injection

Activated oxygen raises the oxygen level of the water creating a more efficient and absorbent drinking water as well as delivering FRESHNESS YOU CAN TASTE™.

ATS-Auto Tank Sanitization

Eliminates the risk of microbiological contamination through adding activated oxygen to your drinking water. A solution that is highly effective, environmentally friendly and that always ensures you have safe, clean water.


The entire front panel and nozzle of our system is manufactured with an antimicrobial surface protecting you and your staff against cross-contamination of germs within the workplace.


Filter Replacement Notification Light

Notifies you as soon as the filter needs to be replaced by the Pure Water Technology service team — ensuring the highest quality of freshness.

Pure Touch Dispense

The ergonomic design delivers an optimum dispense height and spacious dispense area for large containers which prevents germ contamination of the dispense nozzle.

Dispense Area Light

Illuminates the dispense area (4 brightness options) to easily identify drip tray “bullseye” for precise dispensing — keeping the work environment clean of water spillage.

24-Hour System Monitoring

At the core of PHSI’s patented technology is a microprocessor that controls and monitors activated oxygen injection, filter life, water quality, and all other system functions 24 hours a day. Only the 3i can deliver this level of programmability and performance that keeps your water fresh and pure.
