The same commercial quality that makes Pentair Everpure the overwhelming choice for water filtration in restaurants is also available for your home. The H-300-NXT is the first of its kind to be certified by NSF to NSF/ANSI Standard 401, to reduce pharmaceuticals that may be found in your water. These contaminants include: some pharmaceuticals, over-the-counter medications, herbicides, pesticides and chemicals used in manufacturing like bisphenol A (BPA). The Pentair Everpure exclusive precoat filtration technology combines Micro-Pure and a unique pleated filter membrane that is 30% larger than the H-300 filter.
