COUNTERTOP FILTRATION + PREMIUM-QUALITY CARAFE: No plumbing or installation is required for this RO system. Simply plug this portable piece of tech into any power source, and you're ready to fill it up and go! Better yet, the water container is constructed of a high borosilicate glass carafe instead of the traditional plastic, reducing the risk of secondary pollution and making this one of the best countertop water filter systems. 5-STAGE ADVANCED RO FILTRATION: Five levels of filtration, including a remineralization filter, are utilized to ensure the purest water possible. 99.9% of all possible contaminants are filtered out, and the water is enriched with essential minerals, balancing taste and health benefits so you can confidently drink your own tap water. POWER SAVING/WATER SAVING: The water system automatically enters a power-saving standby mode when not in use to reduce power consumption. Leftover water from a cycle isn't deemed wastewater, so more water is saved for various household purposes. FILTER LIFE MONITOR: The countertop water filters last for a long time between 12-24 months to provide 1-2 years of clean drinking water before needing replacement. The lifespan bars diminish over time and usage and the indicator flashes when depleted to ensure timely replacements and continued purity.
