Keeping drinking water clean and healthy is an optimal goal of any workplace. That's why having a professional water filtration system is essential. With any water purification system, regular filter replacement is very important, and our super selection of filtration system accessories will keep your drinking water pure as possible. Many filter cartridges have a surface area made with activated carbon, while a sediment filter has a surface made of polypropylene or cellulose. Filter bags, another filter variation, are made of polypropylene, polyester, and nylon mesh. Zoro also has filter housings for many types of water filters, but sometimes removing those housings can be a pain. But not with one of our versatile filter wrench varieties. These wrenches can unscrew stubborn filter housings in just seconds. Reverse osmosis (RO) is another way to removing water impurities as well. RO systems pass water through a semipermeable membrane, and removes fluoride, chlorine, detergents, lead, pesticides, and nitrates and sulfates from the water. We also have RO systems and accessories.
