Calcite is naturally occurring calcium carbonate media. Upon contact with acidic waters, calcite slowly dissolves and the calcium carbonate raises the pH, which reduces potential leaching of copper, lead and other metals found in typical plumbing systems. It also raises the TDS (Total Dissolved Solids) level of the water and gives it a refreshing mineral flavor for those people that are used to drinking spring or mineral water.
Depending on the pH, water chemistry and service flow, the Calcite cartridge has to be periodically replenished as the Calcite is depleted. In most cases, it lasts up to 6 months.

"Installation is easy after you find an adapter to go from your shutoff faucet to the shark connection. Faucets are usually compression fitttings and faucet hoses have the correct thread and fit, but your regular hardware store does not carry an adapter from compression to Shark. Including that as an option would have saved me a week hunting."

"It was easy to work with the website and ordering processes. Good shipping time and installation process. Time will tell with the products' effectiveness."

"Because the water from our under-sink reverse osmosis system did not taste good, we added this remineralization stage from US Water Systems. We absolutely wanted to be able to trust that it is a US-made product. Our water is now not only perfectly filtered, but also tastes great!"
— Tristan K. (5/5)
"We ran about 10 gallons of RO water thru this remineralizing filter, but couldn't get rid of a slight, unpleasant smell. Had to take the filter out."

"you sent me a bad filter housing. Where the inlet fitting screws in leaks. Even wrapped with Teflon tape it still leaks. I have to go buy a new one. Dry out thencabinet under my sink for the second time. Very disappointed"

"I spent a lot of time searching for a good replacement system for my home. I wanted to make it easy to service, have good flow and be made in USA. All were accomplished and couldn’t be happier. I mounted the filters and pressure tank in an unfinished area in my basement to the foundation at 5 feet high, then routed the lines to the sink faucet and refrigerator. After startup I dumped a couple tanks and the water tastes great! Additionally used the remineralization filter to balance the ph. The techs were supper helpful answering my several calls. Very pleased with the product and its backup support."

"I haven't had any issues, this was a great add on to my RO."
— Sean B. (5/5)
"I flushed the system as required, minerals give water a terrible taste, would not recommend. R/o system works great though"
— Chris B. (1/5)
"Great add-on to my RO system."
