For almost 80 years, Everpure has been providing clear, clean, pure water to businesses and homes, and has positioned itself as a leader in the industry. The filters use a unique pleated design to help filter more water more effectively, without hampering your flow rate. The filgers are tested and certified to meet the highest standards in the industry, which means you can expect great-tasting, healthy water for your home and your loved ones. Everpure uses an exclusive design that flushes the filter’s pleated membrane with a finely-powdered carbon medium that provides an even coating across the entire membrane. The tiny particles of carbon interlock with one another to create a barrier to contaminants, meaning the water that comes from your tap is consistently purified and clean. These precoat filters are NSF-certified to remove more than 99.9% of contaminants measuring only 0.5 micron.
