The Pleatco PRB25-IN filter cartridge is made for filtering water in hot tubs and small pools. The dimensions of 127 mm (outer diameter) × 338 mm (height) × 54 mm (hole diameter) place it in the category of medium cartridges with excellent filtration capacity.
The patented Free Core Flow solid core system ensures maximum water flow through the filter medium even at higher cartridge fouling. The pleated polyester fibre captures even fine particles of contamination originating from the water supply network or brought in by bathers.
The service life of the cartridge is approximately 6 months (one swimming season) with regular maintenance – we recommend rinsing the cartridge under running water every 2 weeks and letting it dry. The cartridge is compatible with dozens of hot tub models from leading global manufacturers, including Hot Spring, Nordic Hot Tubs, Waterway and others.
