  • 3-Stage Filtration System - First stage, Activated Carbon filters chlorine and improve the odor and taste of the water. Second stage, Silver Ion eliminates various tiny matters. Third stage, Hollow Fiber Ultrafiltration Membrane filters pollution, organic chemicals and tiny matters. One more filter stage, one more guarantee.
  • Smaller Filter Pore Size - The filter pore size of Purewell gravity water filter is 0.01 microns so that it can filter out 99.99% tiny materials from the water while other brands' filter pore size is only 0.2 microns. The smaller filter pore size, the higher filtering accuracy. What's more, Purewell water filter system can maintain the optimal flow rate (4 gallon/hour) while the filter pore size is smaller.
  • Non-slip Bottom Design - The bottom of the gravity filter system is made of non-slip material, which can make it more stable and will not fall over or slippery. Ensure the safety of your families.
  • Energy Saving - Relying on the principle of gravity filtration, no electricity is needed. The gravity water filter system is divided into upper and lower layers. The upper layer can be filled with unfiltered tap water, the lower layer will get clean water after filtered. Because it does not require electricity, it can be used indoors and outdoors. NOTICE: When the bottom bucket is full of filtered water, please do not add tap water to the top bucket or it will leak out.
  • Long Lifespan and Replaceable - Purewell purification filter can provide up to 6000 gallons drinking water, the service life of a single filter element is 3000 gallons (According to different water quality, the lifespan of the filter elements would be a little different). But for optimum performance, the filter elements should be replaced every 6 months. NOTICE: The filter element DOES NOT lower TDS value.
