Common Contaminants in tap Water and How Water Purifiers can Remove Them?

There is a strong demand for filtered drinking water from a water purifier due to the global decline in water quality. Water pollutants are microscopic, yet their effects on your health are apparent. As a result, the water coming from your taps may include a variety of toxins that are harmful for your health. We will discuss some common contaminants found in tap water and how water purifiers can remove them.

Chlorine and Chloramine

Chlorine and chloramine are commonly used to disinfect municipal water supplies. While these chemicals can kill harmful bacteria, they can also harm humans. Chlorine can cause skin irritation and dryness, while chloramine can cause eye irritation and respiratory problems. Fortunately, both RO and UV water purifiers can effectively remove these chemicals from tap water.

Heavy Metals

Heavy metals, such as lead, mercury, arsenic, and cadmium, are toxic and can have serious health effects. Lead, for example, can damage the brain and nervous system, while arsenic can cause skin lesions and cancer. These metals can enter tap water through corroded pipes, industrial waste, and mining activities. RO water purifiers are particularly effective in removing heavy metals, using a semi-permeable membrane to trap contaminants.

Pesticides and Herbicides

Pesticides and herbicides are commonly used in agriculture to protect crops from pests and weeds. However, these chemicals can leach into groundwater and contaminate drinking water. Prolonged exposure to pesticides and herbicides can cause health problems such as cancer, congenital disabilities, and neurological disorders. UV water purifiers can effectively remove pesticides and herbicides from tap water by destroying their molecular structure.


like bacteria, viruses, and parasites can cause waterborne illnesses such as cholera, typhoid, and dysentery. These pathogens can enter tap water through sewage overflows, animal waste, and inadequate water treatment. Both RO and UV water purifiers can effectively remove microorganisms from tap water. With its advanced 7 stage purification technology, Pureit Copper RO + UV removes chemicals and harmful bacteria, viruses and cysts.


Fluoride is added to tap water in many countries to promote dental health. However, excessive fluoride consumption can cause dental fluorosis, a condition that affects tooth enamel. Long-term exposure to high levels of fluoride can also cause skeletal fluorosis, a condition that affects bone density.


are compounds that are commonly found in fertilisers and animal waste. When nitrates leach into groundwater, they can contaminate drinking water. High levels of nitrates in drinking water can cause methemoglobinemia, a condition that reduces the blood’s ability to carry oxygen.

How RO and UV water purifiers help in removing contaminants?

When water enters the RO purifier, it first goes through a pre-filtration process, where larger impurities such as sand, mud, and silt are removed. The water then passes through the RO membrane, which removes impurities such as bacteria, viruses, heavy metals, and dissolved salts. The purified water is then collected in a storage tank, ready for consumption. UV water purifiers, on the other hand, use ultraviolet light to kill bacteria and viruses in the water. When water enters the UV purifier, it passes through a chamber containing a UV lamp. The lamp emits UV light, killing all the bacteria and viruses in the water. The purified water is then collected in a storage tank, ready for consumption.

In addition to these two technologies, some water purifiers combine both RO and UV technologies to provide a comprehensive purification solution. These purifiers use a combination of pre-filtration, RO, and UV technologies to remove all types of impurities from the water

How to choose the right filtration technology?

The type of water purifier you choose will depend on the quality of the water in your area and your specific needs. Pureit offers best-in-class technology water purifiers that fit all types of water supply such as Pureit Vital Max RO + UV which offers FiltraPower technology to purify – borewell, tanker or tap water. With its effective UV sterilisation, this water purifier kills 99% of viruses, bacteria and cysts.

In conclusion, tap water can be contaminated with various pollutants that pose health risks. So, if you want to protect yourself and your family from the harmful effects of waterborne contaminants, consider investing in a high-quality water purifier (RO+UV) today.
