The quality of drinking water your family consumes should never be compromised. Refrigerator filters shouldn't be overlooked. While most newer refrigerators do come with a basic factory-installed carbon filter, a refrigerator filter from Pure n Natural Systems will improve the quality of your ice cubes and drinking water by removing the sediment, cloudiness, bad tastes & odors from the water before it even gets to your refrigerator. Plus, our refrigerator filters remove a whole lot more including chlorine, THM's, VOCs, HAA's, lead, arsenic, mercury, heavy metals, insecticides, pesticides, herbicides, and chloramines. Our water filters are one of the best in the industry, and last 10 times longer than standard carbon filters.
