Unlike the undistinguished under-sink water purifiers, this product uses a smooth frame and bright two-tone colors to fit in any kitchen interior. It is about 75% smaller than the existing products to minimize space consumption and does not need to be wall-mounted for installation. Eco-friendly reverse osmosis filter and four other filters always supply the cleanest water and the dual filter arrangement allows users to choose the combination of filters they need. An indicator shows when to replace filters without having to check the unit under the sink and the tool-free filter replacement mechanism makes it easy to use for anyone.
