The top and bottom openings measure 3ft, ensuring compatibility with a wide range of pool setups.

One of the standout features of the PA81 is its impressive 81 sq. ft. filtration area. This large surface area allows for more efficient water filtration, making it an excellent choice for pool owners looking to maintain crystal clear water. The filter is constructed from high-quality trilobal filtration fabric, which is known for its durability and effectiveness.

When it comes to replacement models, the PA81 is compatible with several other filters, including the Aladdin 18101 and Darlly 70811. It's important to note that this is a compatible spare part, and the manufacturers' names and part numbers are used for reference purposes only.

The reinforced center support provides high-powered propulsion flow, ensuring that your pool water remains clean and clear.

Efficiency is a major consideration for any pool owner, and the PA81 excels in this area. The trilobal fabric used in its construction offers a 21-40% higher capacity compared to common point-bond fabric. This unique shape of the fabric fibers helps to catch particles more effectively, increasing filtration efficiency without causing a pressure drop. This means you can enjoy cleaner water for longer periods without frequent filter changes.

Cleaning the PA81 filter is a breeze, thanks to its easy-to-clean design. The trilobal fabric structure allows for quick release of impurities, making maintenance simple and efficient. It is recommended to clean the cartridges every two weeks to maximize your spa's performance and ensure that your water remains in top condition.

In summary, the PA81 Pool Filter Cartridge is an excellent investment for anyone looking to enhance their pool's filtration system. With its robust construction, high filtration area, and compatibility with various models, it provides a reliable solution for maintaining clean and clear pool water.
