Powerful Three-Stage Filtration

The Coral’s powerful three-stage filtration system physical, chemical, and biological contaminants in your water while leaving behind beneficial minerals.

Minerals like potassium, calcium, and magnesium are essential to the human body. Not only do they make your water taste delicious, keeping them in your water is healthier!

However, because these beneficial minerals are dissolved solids, they will register on a TDS meter. A low TDS reading does not mean your water is healthy; these meters cannot detect most harmful water-soluble contaminants. The Coral’s filtration capabilities have been tested and confirmed by an independent organization. Review the individual contaminant list and reduction performance below in our Certificate of Analysis.

Chloramines

Everyone knows it’s dangerous to ingest lead. But what do we know about the dangers of ingesting chloramines, a substance increasingly found in drinking water throughout the US?

First of all, what is chloramine? Chloramine is the chemical compound of chlorine and ammonia. (Fun fact: the most common use of ammonia is in Fertilizer)

Public water utilities use chloramine in their facilities as a cheap and convenient disinfectant in order to meet EPA requirements, even though its use may have very dangerous and unintended consequences.

  • What’s so bad about chloramine? Here’s a start
    • It is highly corrosive to metal – if it’s a bad idea for your home’s plumbing, it’s a worse idea for your body’s plumbing!
    • The EPA admits there are few studies on how chloramine affects human health. And if the EPA doesn’t know, you don’t either.
    • Chloramines are more stable than chlorine – and therefore more difficult to remove.
  • Tested and Certified

    The Coral UC300 system is tested and certified by WQA (Water Quality Association) to NSF/ANSI standards 42 & 53 for the reduction of 60 different contaminants including:

    • Lead

    Rated 5 out of 5 by from looks count Ok I am being vain but I am putting in an entire new kitchen & wanted an attractive water filter spout. This one fit the bill, modern, metal and clean lines unlike competitors that looked too old fashioned. Plus Brondell put ALL info on their website as to how and what it filters unlike Aquasana. And the price was right even got a coupon online and ordered right from company. Also under my counter the unit is sleek and easy to read and change. I recommend.

    Rated 5 out of 5 by from Better than reverse osmosis filtration system I originally purchased a RO (Reverse Osmosis) filtration system from Costco. It only last 3 months before the water became trickling. So I bought this UC300 on Costco again to replace the RO system. It's much easier to install and the water quality is great. The RO system has 4 filters but the 4th filter is mostly for filter the water from the tank. So I really prefer the water does not store in the tank first.

    Rated 4 out of 5 by from It’s the best tasting water filter! The only reason I give this filter a four star is I had a user manual with incorrect instructions. What should have taken a few minutes took us hours to figure out. We had to call support: so if you have an old manual, on page 11, the washer is supposed to be flat side up. If you do that, your golden! We love this filter very much and look forward to using it for years to come!

    Rated 5 out of 5 by from Nice looking and great-tasting water My husband just installed this and, aside from a few issues with a minor plumbing leak, it didn't take long. I did have to run the water longer than 5 minutes for it to be clear. However, now my water no longer tastes or smells like bleach!! Hooray! I've been using a Brita water pitcher, but I can't keep up with the amount of water used. This will make my life so much simpler.

    We have a small house and kitchen,little counter space. Can we install this to flow the water directly through our kitchen faucet? Just two of us so we still wont use filters too fast. Use dishwaser for dishes so all water is to cook or drink from sink.

    What do you do with the other end of the blue tube? The wastewater connector? Do you drill a hole into the tube above the p trap? Thank you for your time. -Linda Rutan

    Asked by: Linnie
    Hi Linda. The blue tube is inserted into the outlet quick connect on the right side. The Coral is not a reverse osmosis system so there is no wastewater and no need to drill a hole. You can find the installation video here: https://www.brondell.com/support/installation-videos/#water.
