NorthFlo's pre-filter is a high performance, premium disposable filter cartridge scientifically engineered to overcome the problems associated with tap, ground and well water. NorthFlo PureStart Pro cartridge filters attach to a garden hose and effectively reduces harmful elements, filtering the water before it enters the pool or spa.

The city or well water you use to fill a pool or spa is by no means ready for instant use. Using the NorthFlo PureStart Pro cartridge lets you enjoy your pool or spa far quicker. Whether you're filling or topping up a spa, above ground or inground pool, the 4-Stage Pure Start filter effectively reduces heavy metals, volatile organic compounds (voc's) and reduces calcium levels.

NorthFlo PureStart Pro 500 is designed for pools or spas up to 2,500 gallons (9,500 litres) in size. Replaces Pleatco PPS25K.
