Is a LG WW 170 EP RO Water Purifier Necessary for TDS Levels Between 40-50 PPM?

When it comes to ensuring access to healthy drinking water, an RO (Reverse Osmosis) system like the LG WW 170 EP can effectively remove contaminants and lower TDS (Total Dissolved Solids) levels. However, if your tap water already has a TDS level between 40 and 50 ppm, you might wonder if an RO purifier is truly necessary.

Effectiveness of RO Purifiers

RO systems are designed to be most effective when dealing with higher TDS levels, above 200 ppm. At a TDS of 40-50 ppm, the reduction in TDS may not be significantly impacted by the purifier. This is because tap water with TDS levels below 500 ppm is generally considered safe for drinking, according to the World Health Organization (WHO).

Mineral Removal

While RO purifiers effectively remove harmful contaminants, they also remove beneficial minerals. For water with TDS already low, such as 40-50 ppm, the removal of minerals can lead to water that lacks taste and essential nutrients. This can affect the overall quality and health benefits of the water you consume.

Health Considerations

Drinking water with TDS levels of 40-50 ppm is generally considered safe and healthy. However, if you have an RO purifier installed in your home, the water may become overly purified, leading to a lack of essential minerals. This is particularly important as many people derive necessary minerals from their drinking water, which is why tap water is often enriched with minerals like calcium and magnesium.

Maintenance of RO Systems

RO systems require regular maintenance, including filter changes and sanitization. Ensuring the system is maintained properly is crucial for its optimal performance. It's important to follow the manufacturer's guidelines to ensure your RO system is functioning at its best.

Alternatives to RO Purification

If your tap water TDS is already below 50 ppm, consider whether an RO system is necessary. While most branded and unbranded RO purifiers can achieve TDS levels under 50, it's worth noting that many purifiers in India are simply badge-engineered systems with common components under different brand names. This means they may offer similar performance and functionality.

For feed water with a TDS level below 500 ppm, other purification methods like UV systems or even boiling water can be sufficient to kill bacteria. Installing a simple UV system or opting to boil water can be a more straightforward and cost-effective solution compared to an RO system.

In summary, while an LG WW 170 EP will certainly provide clean water, you may want to consider whether you truly need an RO system for your current TDS levels. An RO system may not be necessary and could result in overly purified water that lacks essential minerals.
