Solved 10mg/l nitrate problem

Purchased property in 1987; well water had 2.4mg/l nitrate. Water tested in 2020 because of fish tank problems; nitrate level increased to 10mg/l over 30 years. The EPA maximum level for nitrates is 10mg/l. After significant researching I purchased a 4.5"x20" nitrate filter and installed the filter housing in the basement. I picked Crystal Quest because the rated flow capacity of the filters was much higher than other brands. I ran new CPVC piping from the filter housing to the refrigerator and kitchen sink. Originally I was going to add a filtered water faucet to the kitchen sink but decided to just connect it to the cold water side of the regular faucet. The flow rate of the kitchen faucet is well below the max 6 GPM rate for the filter which provided excellent contact time. Initial tests of the water after flushing matched the chart color for 0 nitrates. At my contamination level the cartridge should last for a year with a daily use of 5 gallons. I also installed a GAC filter after the nitrate filter. The taste of the water from the refrigerator has significantly improved.

Nitrate filter

I've bought nitrate filters from a different company which was comparable to yours. When I checked the nitrate level it hardly changed. When I bought the nitrate filters from Crystal Quest the nitrates we're almost zero. So thank you very much

Undersink Nitrate Filter is a Winner

The filter was easy to install, looks nice and is so much easier to use than a pitcher filter that we previously used. Such a pleasure to have water available at the tap.
