The Watts Premier OneFlow Plus Replacement Cartridge Combo Pack comes with one Radial Flow Carbon Block Cartridge and one TAC (Template-Assisted Crystallization Cartridge) for reducing chlorine taste and odors and converting hard minerals into soft particles, thereby preventing build-up inside pipes and retaining beneficial minerals like calcium, potassium, and magnesium.
The high-capacity 20-micron cartridge boasts a substantial dirt holding capacity of up to 2.2 lbs. (1 kg) and achieves remarkable chlorine reduction, capable of treating up to 50,000 gallons (189,000 liters) at a consistent flow rate of 3 GPM (11.34 lpm). The TAC cartridge, on the other hand, is designed to reduce scale formation. Unlike conventional filters, these cartridges operate without the need for chemicals or salt, making them an environmentally friendly choice that supports sustainable water treatment practices. By not adding or removing substances from the water, it ensures that only high-quality drinking water is delivered, free from unwanted tastes or odors and without compromising the presence of beneficial minerals.
Specifically designed for the Watts Premier OneFlowPlus Whole House system, these cartridges are a crucial component for maintaining the system's high performance. To ensure optimal operation and water quality, we recommend replacing the carbon block cartridge every 50,000 gallons or approximately every 12 months and the TAC cartridge every 250,000 gallons or 3 years. The replacement process is straightforward; however, it is essential to turn off the inlet and outlet valves on the system's supply and outlet lines before proceeding with the installation of a new cartridge.
