Is it safe to use a copper water purifier?

Copper water purifiers have been gaining popularity due to claims of health benefits and their natural antimicrobial properties. However, concerns about the safety of these purifiers have also been raised. If you want to know whether it is safe to use a copper water purifier, read on to learn about its potential benefits and risks.

Understanding copper water purifiers

Copper water purifiers operate by infusing water with copper ions, utilising methods like copper vessels, copper-infused filters, or ionisation technology. This copper infusion is believed to offer several potential benefits.

Other than copper’s natural antimicrobial properties, some studies suggest that copper may provide health benefits such as improved digestion, enhanced immunity, and healthier skin.

Potential benefits of copper water purifiers

The potential benefits of copper water purifiers are primarily linked to the antimicrobial properties of copper. Copper ions have been shown to be effective against a wide range of microorganisms, including bacteria, viruses, and fungi. This can be particularly beneficial in areas where water quality is poor or where there is a risk of waterborne diseases.

Additionally, some research suggests that copper may offer health benefits when consumed in appropriate amounts. Copper is an essential trace mineral that plays a crucial role in various bodily functions, such as energy production, iron metabolism, and immune function. Furthermore, copper is thought to improve the taste of water by reducing metallic flavours.

Potential risks of copper water purifiers

While copper is an essential nutrient, excessive intake can be harmful. The World Health Organisation (WHO) has set a provisional guideline value of 2 mg/L (milligrams per litre) for copper in drinking water. Consuming water with copper levels exceeding this guideline value can lead to copper toxicity.

Symptoms of copper toxicity can include nausea, vomiting, abdominal pain, diarrhoea, and liver damage. In severe cases, copper toxicity can even be fatal. Therefore, it is important to ensure that the copper levels in water purified by copper purifiers do not exceed the recommended guidelines.

Factors affecting copper levels in water

Several factors can influence the amount of copper released into water from copper purifiers. The type of purifier plays a significant role, as different types release varying amounts of copper. For instance, copper vessels tend to release more copper than copper-infused filters. The duration of contact between water and copper affects the release of copper ions; the longer the contact time, the more copper is released. 

Additionally, water pH plays a role, as acidic water can leach more copper from copper surfaces. Finally, water temperature can accelerate the release of copper ions, with higher temperatures leading to increased copper leaching.

Ensuring safe use of copper water purifiers

To ensure the safe use of copper water purifiers, choose a certified purifier from a reputable brand that meets safety standards. Regularly test the purified water to monitor copper levels and ensure they are within the recommended guidelines. Adhere to the manufacturer’s instructions for use and maintenance. Consult with a healthcare professional if you have any concerns about the safety of copper water purifiers.
