Daily Life, Better Water

Different moments call for different strengths.

From the first glass to the last shower, the LotusDY and T-18 work together to support clearer, more balanced water across every moment of your day.

Two Patented Systems. One Smarter Standard of Water Filtration.

The T-18 supports water quality throughout your entire home — showers, laundry, appliances, and every faucet. The LotusDY refines and personalizes the water you drink at the kitchen sink. Used together, they form a complete whole-home + point-of-use water-treatment strategy. Save $300 when you buy both.
