RO vs UV Water Purifiers

Here is what you should know about RO and UV water purifiers:

• RO purification: Reduces dissolved salts, heavy metals, and other impurities from water.
• UV purification: Uses ultraviolet light to deactivate bacteria and viruses.
• RO + UV purification: Combines both technologies for broader water purification.
• Water quality: Helps determine which purification technology is suitable for the home.
• Maintenance needs: Vary based on the purifier type, filters, and water quality.

Shop for a water purifier on Easy EMIs from Bajaj Finance. You can convert the cost of your purchase into Easy EMIs at more than 1.5 lakh partner stores, including Reliance Digital, Croma, and Vijay Sales, making your purchase easier to manage.  

RO and UV water purifiers use different methods to make drinking water safer. RO uses a semi-permeable membrane to reduce dissolved salts, heavy metals, and other impurities, while UV uses ultraviolet light to deactivate bacteria and viruses. Choosing between them depends on the quality of the incoming water, its dissolved solids, and the specific contaminants that need to be addressed. This distinction can help match the purifier to everyday drinking water needs.

Shop for a water purifier on Easy EMIs from Bajaj Finance when the model is eligible and available at a partner store. Here is how it works:

• Shop at 1.5 lakh partner stores across 4,000+ cities.
• Select your preferred model and use your Insta EMI Card or Easy EMI Loan.
• Split the purchase cost into monthly payments.

Pro tip: Zero down payment is available on select models. Check with the store if your product qualifies.

The table below highlights the key differences to help identify which purification method suits specific water conditions.

Understanding the type of impurities in the water can make it easier to choose between RO and UV purification.

• RO: Helps reduce dissolved salts, heavy metals, fluoride and other dissolved impurities.
• UV: Uses ultraviolet light to deactivate bacteria, viruses and other microorganisms.
• RO + UV: Combines both methods when water contains dissolved impurities as well as microbial contaminants.
• UV does not reduce TDS: It treats microorganisms without removing dissolved salts from the water.
• RO does not cover every need alone: Additional filtration stages may be useful depending on the source and quality of water.

Maintenance requirements can vary by purifier, but these points help compare their everyday ownership considerations.

Here is a quick price comparison of RO and UV water purifiers across different models.
