IPW Industries Inc. Grooved Melt Blown Sediment water filter cartridge is made of fine melted polypropylene, which is blown and spun in a cylinder-like form. Because this cartridge is grooved, it provides increased surface area and longer filter life, it has no surface binders and reduces flow and increase change-out frequency. The main function of grooved sediment filter is to remove large and fine particles from a drinking water, such as sand, dirt, silt, and rust particles. These filters have graded density layers, meaning the outer layers are more porous, catching larger particles, while the inner layers are a finer micron, catching smaller particles. Each filter cartridge is individually shrink-wrapped. Features: Micron rating: 5 Micron Dimensions: 10? x 2.5? Lifetime: Replace two or three times a year, depending on the water quality Removes dust, particles, and rust Additional Details ------------------------------ Bullet point: 6 Pack Of 5 Micron Grooved Gradient Density Multi-Layered Melt Blown Sediment Filter Cartridges.|10 inches x 2.5 inches - Universal water filter replacement fits any standard 10 inch RO and Whole House systems.|4 - 6 months / 20000 - 30000 gallons (depending on the water quality).
