Including filter system and high-performance Nitrite filter.
Nitrite is a nitrogen-based compound that can enter drinking water when the local nitrogen cycle is disrupted. Sources include fertilizer runoff, septic or wastewater impacts, and the breakdown of organic material that can leach into groundwater. Because nitrite is colorless and usually has no distinct taste or smell, it can be present without visible clues. The only reliable way to know if nitrite is in your Fidelis water is to have it professionally tested.
For many Fidelis homeowners—especially those on private wells—testing for nitrite is an important part of routine water care, particularly after heavy rains or changes in nearby land use. Even customers on municipal systems may opt for testing to be certain about what’s coming from their taps. Nitrite and nitrate are closely related and can transform under certain conditions, so identifying which compound is present in your sample helps determine the most effective treatment.
To reduce nitrite across an entire house, the most dependable single-filter solution is a whole-house reverse osmosis system. RO relies on a semi-permeable membrane that removes many dissolved ions, including nitrite, rather than only addressing taste or odor. Because nitrite is dissolved in water, standard carbon filters alone won’t reliably remove it. A whole-house RO system protects all fixtures and appliances in your Fidelis home by treating water before it reaches taps and baths.
An effective whole-house reverse osmosis setup for nitrite reduction typically includes prefiltration to protect the membrane and postfiltration to refine water quality. Proper sizing and flow-rate selection are important to maintain consistent performance without noticeable pressure loss around your Fidelis property. Membranes can foul over time, so regular maintenance and timely filter replacements keep nitrite reduction steady; Mr. Pure Water can recommend the right configuration based on your water test results and household needs.
