​We offer 3 types of Nitrate Filters:
  • The 2 in 1 Standard Nitrate Eater Series built to filter high nitrates and soften hard water.
  • "The Nitrate Only" Nitrate Eater Series built to remove high nitrates only - *these systems are installed after your existing water softener. 
  • Twin Nitrate Eater systems are built to provide a continuous flow of treated water with dual alternating filtration tanks.
Why remove nitrates? Nitrate levels in many water wells are often high. Over 60% of nitrate enters water from agricultural land. High concentrations of nitrate in water can cause methaemoglobinaemia in very young children (blue baby syndrome). The nitrate is converted to nitrite in the body which in turn interferes with oxygen up take in the blood. The current regulatory standard of 10 mg/l nitrate is derived from the EPA primary drinking water standard. which is intended to ensure that drinking water will not cause methaemoglobinaemia.

​How to remove Nitrates: The most common method of removing nitrate is with an ion exchange resin. The nitrate rich water passes over a resin where the nitrate is exchanged for chloride ions. When no more nitrate can be exchanged the resin needs to be replaced or regenerated by rinsing with salt. Reverse Osmosis can also remove nitrate from water. The water passes through very small pores at a high pressure. This combination stops most contaminants just allowing water molecules through. However RO systems are relatively expensive, may require the water to be pre-treated, and often remove beneficial minerals. Our Nitrate Eater's listed below are a cost effective alternative to a whole house reverse osmosis system.
Nitrate Filter Review:​
​"Just a note to inform you how pleased we are with our new nitrate eater. The water is cleaner clearer and tastier than it has ever been. I also had the the water tested for nitrates for the second time and they went from 20ppm to .078ppm. This what I had hoped for. Thank you for such a great system.
Kind Regards,"
