POOLPURE PAS50SV-F2M Spa Filter – Replaces Unicel 6CH-502, Filbur FC-0311

Crystal-Clear Spa Water Starts with the POOLPURE PAS50SV-F2M

Meet the POOLPURE PAS50SV-F2M spa filter, a versatile cartridge designed to slide into a range of popular filtration systems. It measures 8 inches in length with a 6 3/4 inch outer diameter and features a convenient grip handle plus a bottom two-inch MPT for a secure seal. This is a compatible part, referenced to fit models like Unicel 6CH-502, Filbur FC-0311, and Excel Filters XLS-604, giving you a straightforward replacement option without relying on a single brand.

What makes this filter stand out

In home spas and hot tubs, water clarity comes from filtration that reaches from surface to depth. The PAS50SV-F2M offers a 50 sq ft filtration area and uses trilobal filtration fabric to balance debris capture with steady water flow. With Dirt-Locking technology, the filter is designed to trap more debris before it has a chance to circulate, helping your spa feel inviting after a long day.

• Compatibility & Certification: Fits PAS50SV-F2M, Unicel 6CH-502, Filbur FC-0311, and Excel XLS-604; NSF/ANSI 50 certified; IAPMO tested for reliability.
• Filtration Performance: Up to 50 microns with strong debris capture, capable of reducing hair, leaves, dust, sediment, and sand in your spa water.

Real-life spa sessions benefit from a filter that supports easy maintenance and steady performance. Picture a quiet evening soak where water feels crisp and inviting, with fewer visible particles and a more consistent temperature as the circulation keeps the water well mixed across the tub.

Durable design for everyday use

• Ease of use: An enhanced grip handle makes installation and removal smoother, especially when you’re multitasking before a soak.
• Filtration architecture: Trilobal fibers are designed for easier stain capture and release, helping you clean the cartridge with less effort each month.
• Longevity: The filter fabric is about 25% thicker than standard filters, with chlorine-resistant end caps, extending life by roughly 20–30% under typical use.
• Care note: This cartridge is not designed for backwashing; backwashing may cause cracks or permanent damage.
