    Pentek ECP5-20BB Filter Advantages

    The Pentek ECP5-20BB water filter cartridge has a special formulation of resin-impregnated cellulose and polyester fibers. The Pentek ECP5-20BB water filters provide higher wet strength than regular cellulose cartridges. This filter also provides high flow rates and dirt-holding capacity, while maintaining extremely low pressure drop. The Pentek ECP5-20BB replacement filter cartridge has minimal unloading and media migration. The Pentek ECP5-20BB water filter media is pleated around a polypropylene core for added strength and the ends are immersed in a thermosetting vinyl plastisol. Embedding and sealing each end of the pleat block in this fashion fuses the components together, forming a united end cap and gasket. This ECP water filter cartridge contains more media surface area than most competitive cartridges containing around 36 square feet of media.

    Pleated Filter Media

    The Pentek ECP5-20BB uses pleated filter design to maximize contaminant exposure to filter media. More time along the media allows for higher capture and retention of unwanted contaminants. This also allows for greater amounts of larger particles of sediment and sand to collect within the pleats of the filter. This pleated design enhances structural stability and helps increase the performance of the filter.

    Universal Filter Sizing

    The 20 X 4.5 Pentek ECP5-20BB pleated cellulose and polyester replacement filter is built to fit 20-inch x 4.5-inch filter housings. This standard sizing allows this filter to easily replace existing styles of whole house filters for housings requiring 20 x 4.5 inch filters. The ECP5-20BB goes to work immediately providing cleaner, fresher water for up to six months. Enjoy cleaner better water with your whole house replacement filter today.

    The Pentek ECP Series cartridges have end caps that are color-coded for micron rating:
    Tan = 1 micron
    White = 5 micron
    Blue = 20 micron
    Yellow = 50 micron

    NOTE: The Pentek ECP5-20BB replacement filter cartridge is recommended for chlorinated water supplies. It is not recommended for non-chlorinated water supplies. Cellulose may start to break down if there is bacteria present in well water or other non-chlorinated water supplies.

    NOTE: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
