About This Item
The Unicel 4000 Series C-4995 is a 100 sq. ft. replacement filter cartridge engineered for Waterway top load and in-line spa filter systems. With 222 precision-formed pleats of 3 oz. Reemay 2033 spunbond polyester media, it delivers thorough debris capture and dependable water clarity — sized to drop directly into Waterway 817-1000 housings and compatible equipment from leading spa manufacturers.
⚠️ IMPORTANT: FILTER AREA NOTE
The Unicel C-4995 is rated at 100 sq. ft. per official Unicel specifications. Some listings — including the original Waterway OEM part (817-1000) — reference 95 sq. ft. Both the Unicel replacement and original OEM cartridge are dimensionally identical and directly interchangeable. Always verify fit using the dimensions below.
