Unicel SC3-SR137 137 Square Foot 3 Oz Media Pool Filter Cartridge, 216 Pleats

Shake off the summer heat in a cool pool. Make a splash in the cleanest swimming pool in the neighborhood with Unicel SC3-SR137 Replacement Filter Cartridge. Featuring 137 square feet of 3-ounce basis weight media made of 100-percent polyester Reemay material, this pool cartridge filter ensures high performance and dependable filtration over time. The uniform pleats and Reemay media deliver higher dirt-holding capacity and more time between cleanings. Plus, the smooth surface of the media makes it easy to maintain, resists degradation from chemicals, stands strong under pressure, and holds up to the rigors of multiple cleanings. For optimal lifespan, clean the elements as per instructions and use a soft brush cleaning tool or filter cleaner for easy maintenance. Please note that the cartridge life depends on routine maintenance and pool water chemistry. Change your filter when there is a shorter cycle between cleaning, low water flow rate or high differential pressure, when the media has a tear, or if the center core collapses. The end caps are made of durable plastic that resists damage from chemicals for reliability throughout the filter's lifespan. The blue top and orange bottom have a 4-3/16-inch ID and open configuration for ease of removal and replacement. Additionally, the bottom includes 12 concentric slots. This SC3-SR137 model of pool filters is compatible with Sta-Rite 135TX, 135GPM-TX, 135TXR, and PTM-135. The Unicel SC3-SR137 Cartridge Pool Filter is clearly the optimal choice to keep your swimming pool water sparkling.
