Based on our legendary best seller model RCC7, featuring 100 GPD reverse Osmosis membrane, 11-Watt UV Lamp with Smart Flow Sensor and 24-Volt Boost Pump, RCC1UP is a comprehensive Reverse Osmosis water filter system in the market. Most UV filters in the market have the lamp powered on constantly; we have developed the innovative transformer that features an inline Flow Sensor. Whenever you turn on the drinking faucet and water starts flowing, the UV lamp is powered on automatically and turns on and off along with water flow. This prevents a potential heat hazard and extends the life of the UV light bulb. ISPRING RCC1UP generates clean filtered water for drinking, cooking, hydroponics, aquariums and more. The unit removes hardness, chlorine, heavy metals, and other contaminants. The equipped 11-Watt UV Lamp makes this model more suitable for potential highly contaminated water source such as well or groundwater. The alkaline filter provides pH balanced drinking water for human body.
