This Pentek CRE-1 ceramic filter cartridge reduces protozoan cysts and fine sediment in residential drinking water. It has a nominal (85%) filtration rating of 1 micron, and 99.95% efficiency for the removal of protozoan cysts. This cartridge is made of sintered ceramic media with thermoset polymeric end caps for strength and rigidity. The nitrile butadiene rubber (Buna-N) gasket seals the cartridge against the housing (sold separately). This filter can be cleaned several times with a sponge or nylon brush. The cartridge has an initial pressure drop of 19 pounds per square inch (psi) at a recommended flow rate of 1 gpm, and it operates over a temperature range of 40 to 125 degrees F (4.4 to 51.7 degrees C). This ceramic filter cartridge is for use in residential drinking water purification.

The nominal filtration rating is for a particle removal efficiency of 85%. Protozoan cysts include Giardia, Entamoeba, Cryptosporidium, and Toxoplasma.
H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.
Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes. They are made of densely packed synthetic or natural fibers that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced. Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.
