Do RO Purifiers Affect the pH Level of Water?

Water purifiers can be classified into various types based on their purification technique. Some purifiers use UV radiation to get rid of various living pathogens, while some use UF filtration for the same. RO purification technology is used to remove excess salts from hard water. Salts that are hard and considered unhealthy for the human body are Calcium & Magnesium salts and an RO purifier removes all unhealthy minerals through the process of reverse osmosis.

The drinkable TDS limit is 500 ppm. TDS stands for Total Dissolved Solids and a maximum number of 500 parts per million dissolved solids are allowed in water to categorize it as drinkable. The minimum TDS is supposed to be 30 parts per million. A good RO purifier has a TDS controller that keeps this TDS value in check and ensures that essential minerals aren’t removed from water.

How RO Purifier Works?

RO purifier uses Reverse Osmosis technology to purify the water. This is a semi-permeable membrane that lets the water and essential minerals through. The harmful minerals and other pollutants stay behind. The impure water is then discarded and pure water is then passed through a disinfection technology, which can be a UF filter or UV light lamp or both. This disinfection technology gets rid of any harmful pathogens that are present in water and cause water borne diseases.

Some RO purifiers also have activated carbon filters that help remove some pollutants even before the RO process is started. RO purifier is certainly a complete purifier. It eradicates any possibility of problems like kidney stones and other cardiovascular diseases. With the help of UF and UV filters, it also provides disinfection of harmful pathogens. Although RO removes various pathogens on its own, having UV-UF filters ensure double protection.

pH Level of Drinking Water

The pH level of drinking water should be in the range of 6 to 8. The neutral pH level is 7 and water is generally considered the base for pH measurements. Substances that are below 7 are considered acidic and substances above that are considered basic. Although you can drink water that has 6 – 7 pH level, it is considered healthier if you drink water that has pH value above 7 but below 8.

However, if you go beyond the 6-8 limit, your body might start experiencing acidity or basicity. The human body does have a system to keep its pH level neutral, which is why water’s pH level doesn’t change the body’s pH level. But going beyond the range would malfunction this system and you might start experiencing uneasiness.

pH Level of Water and RO Purification

RO purification slightly changes the pH, but it does so in a healthier way. It tries to keep the pH in check using the TDS Controller. Water pH is strictly kept from 6-8, but RO doesn’t affect the pH to that extent. As harmful salts leave the pure water, the pH falls into the drinkable range automatically.

As the body generally keeps the pH in check, RO purifiers aren’t required to keep the pH in check. Even if the pH of purified water is higher or lower than the neutral range, the body maintains its pH state.

Conclusion

The pH level of water isn’t a considerable factor to decide the drinkability of water due to which RO purifiers aren’t generally responsible for maintaining this value. The pH is automatically neutralized when we drink water. Therefore, you don’t have to worry about the pH measurement while purchasing an RO purifier.
