Can I use RO water purifier for soft water?

When it comes to drinking water, safety and taste matter the most. However, with numerous water sources—borewell, municipal tap, and tanker—many households wonder: Can I use an RO water purifier for soft water? If you’ve been asking the same, you’re not alone.

Let’s break down what soft water is, how RO works, and when it’s ideal to use a RO water purifier—even if your water isn’t hard to begin with.

What exactly is soft water?

Soft water typically has low Total Dissolved Solids (TDS)—usually under 150 ppm (parts per million). It doesn’t contain high concentrations of minerals like calcium and magnesium that are present in hard water. Soft water is smooth on the skin, doesn’t leave stains on utensils, and helps appliances last longer.

If your home gets soft water (often through municipal supply), you might wonder if investing in an RO purifier is overkill.

But here’s the truth: TDS is only one part of the story.

Does RO work for soft water?

Yes, you can use an RO water purifier for soft water—but with a few smart considerations.

While soft water may have lower mineral content, it can still contain:

• Microbial impurities (bacteria, viruses)
• Chemical pollutants (chlorine, pesticides)
• Heavy metals (lead, arsenic, mercury)
• Organic matter and industrial residues (common in city water)

An RO water purifier—especially when combined with UV and MF (Microfiltration)—ensures these hidden contaminants are removed, offering complete protection.

Why do you still need RO in Indian cities, even for Soft Water?

In India, most urban homes receive water through municipal pipelines, which are often decades old.

• Unpredictable water sources: Even if you get soft water today, your society may switch to tanker supply tomorrow. A multi-source compatible RO like Pureit adapts easily.
• Better taste and odour removal: RO removes chlorine-related smells and unpleasant tastes, often found in treated municipal water.
• Boiling is not enough: According to the World Health Organization (WHO), boiling removes bacteria but not heavy metals or dissolved impurities. RO does both. 
• Safety for vulnerable groups: RO-purified water is gentler and safer for kids, the elderly, and those with digestive issues.
• Year-round protection: From summer contamination spikes to monsoon overflows, an RO purifier works 365 days to ensure safe hydration.

Additionally, many apartment complexes in cities like Mumbai, Bengaluru, and Delhi store tanker or municipal water in overhead tanks, which are not always cleaned regularly. This introduces microbial risks—even in soft water.

That’s why a robust RO+UV+MF purifier makes sense for Indian homes, regardless of whether the water is soft or hard.
