Ayro HT Plus is created from cutting edge technology featuring all of the benefits of healthy water with alkaline minerals and antioxidants while filtering out harmful chemicals from the tap. It is equipped with a six-layered high-powered water cleaning filter with alkaline minerals and antioxidant media creating delicious and healthy water. First, regular tap water is filtered through a mechanical filter reducing sediments. Then, water passes through the granular activated carbon, KDF media and o.5 micron carbon block. At the last stage, water is recharged with alkaline minerals and antioxidants. As a unique countertop filtration system with antioxidants, Ayro HT Plus is perfect for your home and office. It is small enough to travel with and easily connects to virtually any hotel room faucets. Note: Certain areas contain heavy sedimentation in their local tap water, and may require installation of sediment pre-filter. Made in USA.
