Combining industry leading filter technology, advanced features, and intuitive design, CUCKOO’s water purifier line does exactly as advertised: purifies your drinking water for your health, safety and convenience—all while instantly modernizing your living or office space.

CUCKOO’s Reverse Osmosis filters feature 4-stage filtration: a sediment filter to rid your water of impurities like rust, deposits, particles, moss, and sand, a pre-carbon filter to remove heavy metals, odors, chlorine, and VOCs, a reverse osmosis filter to shed your water of lead, chromium, fluoride, and microbes, and finally a mineralizer to add electrolytes, natural calcium and potassium back to your water for healthy and pH balanced alkaline drinking water.
