Unicel 5CH-512 Replacement Spa Filter Cartridge – Premium 50 Sq Ft Filtration
The Unicel 5CH-512 Spa Filter Cartridge is a premium, OEM-quality replacement filter designed to restore proper filtration, water clarity, and circulation performance in compatible spa and hot tub systems. With 50 square feet of pleated filtration media, this cartridge provides ample surface area to capture fine debris, body oils, and contaminants that accumulate during regular spa use.
Spa filtration systems operate in warm, high-bather-load environments where water quality can decline quickly if filtration is compromised. A clogged or worn filter restricts flow, increases strain on pumps and heaters, and leads to cloudy or unsanitary water. Replacing an aging cartridge with the Unicel 5CH-512 helps maintain balanced water conditions while protecting critical spa equipment.
Unicel filters are widely trusted by spa professionals for their precise fit, durable construction, and consistent performance under demanding conditions.
