Ametek # 155360 DGD Series is manufactured from 100% pure polypropylene fibers and are sized for use in our Big Blue® filter housings. They are designed for purity and will not impart taste, odor or color to the liquid being filtered. Also, the polypropylene construction provides superior chemical resistance and is not prone to bacterial attack. The DGD Series advanced design combines selective "final filtration" with appropriate "pre-filtration." The larger diameter of the pre-filter reduces the particle load to the post filter, allowing it to operate at higher velocities. This increased depth provides for very high particulate reduction efficiencies and loading capacities. Order a case and save even more. Learn More

    Pentek WP1BB20P #355222 Polypropylene 1 micron String Wound Sediment Replacement Water Filter. WP Series cartridges are manufactured from a durable polypropylene cord that is wound around a rigid polypropylene core. They are an economical solution to reduce fine sediment, including sand, silt, rust and scale particles. WP Series cartridges are wound in a precise pattern around the core providing greater surface area. The result is higher dirt-loading capacity and greater efficiency than standard wound cartridges like the CW. These string-wound cartridge styles are capable of withstanding temperatures up to 165ºF (73.9ºC), and will accommodate flow rates between 7 and 10 GPM with minimal pressure drop. WP Series cartridges are suitable for a wide variety of sediment filtration applications, including municipal and well water as well as many industrial fluids. This is a very high quality sediment filter. Learn More

    TDS Meter - Tester. The Only Way To Know If Your Reverse Osmosis RO Membrane Is Performing Correctly - Tests for TDS - Total Dissolved Solids. A Must For All RO System Owners. Compare Incoming Feed Water To Treated Water - Replace Membrane If Less Than 80% of TDS Is Being Removed - The lower the TDS level in the water, the more efficiently your body's cells actually get hydrated by the water that you drink. The higher the TDS levels in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level. Simple to use for Reverse Osmosis membrane monitoring. We really like this tester and think that anyone who wants to know about the quality of their water should have one of these TDS Meter Testers to monitor their RO membrane. Learn More
