## Description

The Watts Premier OneFlow Plus Radial Flow Carbon Block Cartridge is an advanced filtration solution engineered for chemical-free scale reduction and protection. This innovative cartridge converts hard minerals into soft particles, effectively preventing scale build-up inside pipes while retaining essential minerals such as 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). Unlike conventional filters, this cartridge operates without the need for chemicals or salt, making it 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, this radial flow carbon block cartridge is a crucial component for maintaining the system's high performance. To ensure optimal operation and water quality, it is recommended to replace the cartridge every 50,000 gallons or approximately every 12 months. 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.

What a difference this product made with both the taste of our water and with water deposits on plumbing. Works excellent and super easy to change out the filter. Lasted a full year.
