POOLPURE Antimicrobial PLFC-8465-M Spa Filter 65 sq. ft - 2pack

In this review the POOLPURE Antimicrobial PLFC-8465-M spa filter earns a recommendation for hot tub owners who want a reliable, easy-to-maintain replacement that helps keep water clearer and healthier. The biggest reason to buy is its NSF/ANSI 50 certification and antimicrobial fabric treatment, which combine to deliver trusted filtration performance and inhibit microbial growth throughout the cartridge life. It is sold as a 2pack and fits a wide range of popular spa models, making it a practical spare-part choice for regular maintenance.

Key Features

• NSF/ANSI 50 Certified: Independent testing confirms the filter meets industry standards for pool and spa filtration, so buyers can expect consistent water quality.
• Antimicrobial Filtration Fabric: Fabric infused with an antimicrobial blending material helps inhibit microbial growth on the cartridge for continuous protection during use.
• Replacement Compatibility: Designed to match length 10 1/2 in and outside diameter 8 1/2 in with 3 in top/bottom openings, it replaces several common models for broad fitment.
• 65 sq. ft. Filtration Area: A generous filtration surface area improves debris capture and extends service intervals compared with smaller cartridges.
• Easy to Clean: Trilobal fabric structure releases trapped impurities during rinsing, restoring performance and reducing the need for frequent replacement.
• Longer Service Life: Durable construction and reconditionable materials help the cartridge last 1-2 years with proper maintenance, delivering value over time.

Who It's For

This filter is best for hot tub and spa owners who use compatible Watkins, Pleatco, Unicel, Filbur or Tiger River cartridges and want a cost-effective two-pack for regular maintenance. It suits families or frequent users who prioritize cleaner water and the added antimicrobial protection that works throughout the life of the cartridge.

Those who should look elsewhere include owners of non-compatible filter sizes or top/bottom opening dimensions, or users who require OEM-branded parts for warranty reasons, since POOLPURE is an independent compatible replacement rather than an original manufacturer item.
