## Overview

The Watts Premier Cartridge Combo Pack includes a high-capacity 20-micron Radial Flow Carbon Block and a TAC cartridge designed for the OneFlow Plus system. Together, they reduce chlorine taste and odors, filter up to 50,000 gallons annually, and prevent scale buildup chemically-free for up to 3 years, delivering clean, mineral-rich water throughout your entire home.

## Description

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.

Review: Wonderful having full house filtered - Love being able to take a drink from any faucet and enjoy clean smelling and tasting water. Water pressure dropped significantly after 14 month. Swapped to find the old Olten cakes with sediment from the municipal water system in Washington DC. Will just make a pint of swapping it every 9 months. Yes, it’s a lot more expensive than using a drinking water filter for drinking water only. But we find the value to be well worth it. There’s clearly a benefit to our fixtures and plumbing. We’re confident that all of the water in the house has been well filtered. And we generally just drink more water when we can go to any tap in the house and fill up a cup rather than going down to the kitchen and pouring from a Britta filter.
Review: Easy to Install - A friend of mine installed this for me. We had to refer to a video but it was very easy once we viewed it. I knew it was getting near the time to change the filter because my water was tasting icky. Within minutes my water was great again. This filter appears expensive but considering it is for a year, it’s definitely worth the money.
