We stock a full range of replacement K23-- Series Omnipure Filter Cartridges. The success of the K-Series filter is directly attributable to the innovative Quick-Connect ™ fittings that are incorporated into the design. These fittings are unique in two ways. First, they allow for the installation of the inline filter in a matter of seconds. Inlet and outlet tubes are simply snapped into place and secured using a patented collet system. Second, the fittings are molded directly into the filter body and cap as a single unit. This reduces the chance for weeping or seepage. Cap and body are spin-welded together producting a smooth, consistent seal without the use of glues or binders that can cause comtamination. The result of these design and production techniques is a reliable filter that is fast and easy to install. One of the primary uses of this product is as a system component. The benefit is derived from the fitting being molded directly into the filter cap, greatly recucing clearance. Shown here (right) is a reverse osmosis system with the traditional 12” x 2.5” filter configuration. Notice that all the filters are uniformly attached. This results in the most efficient use of available space and greater filtering performance in a smaller overall area. The K-Series filter is available in 6”, 8”, 10”, 12” or 14” lengths manufactured in 2” or 2.5” diameters.
