Water comprises minerals, compounds, and elements essential in replenishing the body’s nutrient levels, and that’s why drinking high-quality water is a must, by trying the nitrate water filter you will achieve exactly that.

But to some extent, these compounds might exceed their required quantities consequently becoming harmful to human consumption.

Examples of these components include; oxygen, hydrogen, sodium, potassium, and nitrates only to tag a few.

The standard quantities recommended are 10mg/liter of nitrogen (equivalent to 45mg/liter of nitrates).

Any amount exceeding this level would possibly lead to Methemoglobinaemia (blue baby syndrome), a condition where the excess nitrates could lead to the formation of nitrites in the blood, reducing the supply of oxygen to the body.

Infants younger than 6 months are highly susceptible.
