At Cuckoo, we dedicate ourselves to designing water purifiers that are capable of producing drinking water that meets the standards set by the World Health Organization.

“All people, whatever their stage of development and their social and economic conditions, have the right to have access to an adequate supply of safe drinking water.”
World Health Organization (WHO), Guidelines for Drinking-Water Quality, 2nd Edition, Volume 2: Health Criteria and Other Supporting Information

WHO’s Standards

pH 6.5 – pH 9.5

The optimum pH will vary  but is often in the pH level  of 6.5 – 9.5

Low-Mineral Content Water is not Ideal Drinking Water

Low-mineral content water – in the light of the absence or substantial lack of essential minerals in it – is not considered ideal drinking water.

The Contamination of Heavy Metals

“Contamination can occur within the distribution system through leaching of chemicals and heavy metals from materials such as pipes, solders/jointing compounds, taps and chemicals used in cleaning and disinfection of distribution systems.”

Diseases can Spread Through Drinking Water

“Infectious diseases caused by pathogenic bacteria (E.coli, Salmonella), viruses, parasites are the most common and widespread health risk associated with drinking water.”

Cuckoo’s Standards

pH 7.3 – pH 7.9

CUCKOO’s mild-alkaline water has an average pH level of 7.3 to 7.9.

Cuckoo Water Purifier Has Mineral-Rich Alkaline Water

Cuckoo Water Purifiers are designed to dispense mild-alkaline water that is rich in minerals which ideal as drinking water

Free of Heavy Metals

Dangerous heavy metals, such as lead, cadmium and arsenic that came from material such as pipe, solders and contamination within distribution system through leaching of chemical are filtered by Cuckoo’s Nano Positive Filter. This is to ensure the drinking water is clean.

Eliminates 99.99% of Harmful Bacteria and Viruses

Cuckoo’s state-of-the-art filtration system removes harmful bacteria and viruses that came from the water supply system and ensure the water is safe to drink.
