It's ideal if you:

— Want to specifically target nitrates

— Already have a filtration system and want to upgrade it

— Prefer a simpler alternative before moving to full reverse osmosis

Overview

Nitrates are one of the most difficult contaminants to remove from drinking water. They're common in groundwater and agricultural regions, and unlike chlorine or sediment, they pass straight through most standard filters.

In New Zealand, water can meet legal standards while still sitting above levels associated with long-term health research — the Maximum Acceptable Value is 50 mg/L, while the health-based guideline is 0.14 mg/L. The NIT10 filter is a focused solution: using nitrate-selective resin, it reduces nitrate levels where standard carbon filtration can't, without requiring a full system overhaul.

Choosing the right level of protection:

→ Want a targeted solution nitrate filter (this product)
→ Want full-spectrum protection reverse osmosis
→ Want simple taste improvement carbon filtration

FAQ

Find the most frequently asked questions below.

Nitrate removal filters, particularly ion exchange filters, work by replacing nitrate ions (NO₃⁻) with other ions, commonly chloride ions (Cl⁻).
Ion Exchange Resin: The filter contains a resin that is saturated with chloride ions. This resin is typically made of tiny beads of organic polymer that have sites that hold chloride ions weakly.

Water Flow: As water containing nitrate ions flows through the resin bed, the nitrate ions are attracted to the resin due to their charge.

Ion Exchange: The resin beads release chloride ions into the water in exchange for the nitrate ions. This process happens because the resin has a higher affinity for nitrate ions than chloride ions, causing the nitrate ions to displace the chloride ions.

Removal of Nitrates: The nitrate ions attach to the resin beads, and the now chloride-rich water exits the filter. This reduces the nitrate concentration in the water.
Preparation: The ion exchange resin is preloaded with chloride ions. This is often done by soaking the resin in a solution of sodium chloride (NaCl).

Nitrate Capture: As the contaminated water passes through the resin bed, nitrate ions are attracted to and held by the resin, while chloride ions are released into the water.

Regeneration (if applicable): Over time, the resin becomes saturated with nitrate ions and loses its effectiveness. It can be regenerated by flushing it with a concentrated salt solution, which replaces the nitrate ions on the resin with chloride ions again.

This method is effective for nitrate removal and is commonly used in water treatment systems to ensure safe drinking water. However, it does increase the chloride content of the treated water, which is usually not a problem since chloride is commonly found in water and is generally safe at the levels produced by the ion exchange process.
The filter significantly reduces nitrate levels, but exact removal depends on your incoming water quality. For near-complete removal, reverse osmosis systems are the most comprehensive option.
The lifespan depends on your starting nitrate levels:
- Higher nitrate levels → shorter lifespan
- Lower nitrate levels → longer lifespan
As a guide:
- Around 1200 litres at 10 mg/L
- Around 2400 litres at 5 mg/L
This filter is designed to complement existing systems. It can be added to compatible setups where targeted nitrate reduction is required.
Most common filters (like carbon) improve taste and remove chlorine, but do not remove nitrates.
Specialised media, like the resin used in this filter, is required.

NITRATE X – Filter System - Nitrate free water finally in our home in Rolleston!!

Thanks to the NITRATE X system we can now enjoy water that is nitrate free. Selwyn water is saturated with nitrate, thanks to the dairy farming industry and even though the council says "within limits" its at the higher end and with the incidence of colon cancer, birth defects, nitrates should be at least at the lowest end. We now have good safe water at home. The customer service provided by Dean Fideles is amazing. So helpful and prompt and transparent. The system is not expensive. The plumber cost almost the same cost. The system is recommended and the value is much more than the cost. Recommended.

Great

Happy Customer

Fantastic customer service and prompt delivery!
Have combined with FluorEx Max cartridge for an under sink set up - working well and tasting great.

All is well thank you

Helped me with the order. Friendly, fast and efficient.

We value the quality

I can only say that I really value the quality of Ionza products, as well as Josef's knowledge and passion

Removes 99% nitrate

So happy about our water testing this morning. We got a result of 6.25 on nitrate for our tap water (quite high) and our filter water was only 0.065 (practically nothing) so this cheap nitrate filter is removing 99% of our nitrate!!!
