If you’re searching for an ideal water purifier, we hope that you know that buying just an RO based water purifier is not enough. By using an only RO based water purifier, sure, you’re drinking safe to consume water, but RO only filtration also removes the essential minerals from your daily water consumption. It is crucial that you consume minerals enriched water as the water accounts for providing 6% to 30% of essential minerals to the body daily. Therefore, many brands now offer a Post-RO mineral filter to add back some minerals in the water, while some brands use the by-pass line for mixing non-purified water with purified water to maintain the TDS level desired by the consumer.

Whirlpool Purasense RO Water Purifier Review

Why I Bought the Whirlpool Purasense RO Water Purifier?

The Whirlpool Purasense RO water purifier was an obvious choice for me after I went through all the brands available in the market and compared them against the Whirlpool Purasense RO Water Purifier. First and foremost, it comes from Whirlpool, which is a global and trusted leader in the home appliances category. Secondly, it comes with a host of important features required in a water purifier like AI Technology which automatically checks the TDS of the water and adapts the filtration process accordingly, 9 Stage Purification which includes Micro Block Protection, Calcium Booster and Activated Carbon Block Design. Finally, it has India’s first* DIY Filter Replacement technology that solves for one of the biggest problems one faces after buying a water purifier i.e. buying 100% genuine filters.

Let me walk you through each of these benefits and the technology that helps you get pure and healthy water.

Whirlpool Purasense RO

Why the Whirlpool Purasense Range of RO Water Purifiers are the best in the Category?

Whirlpool’s PuraSense RO Water Purifier delivers several key features such as:

1. India’s First* Do-It-Yourself Filter Replacement

Whirlpool Purasense RO water purifiers give you the ease to change the water filters, all by yourself. Changing the filter is a quick 4-way step process specified on the front panel of the water purifier.

2. Adaptive Intelligence

Whirlpool Purasense AI Microprocessor

Did you know that a normal RO process also removes essential minerals from the water? However, Whirlpool Purasense RO water purifier uses Adaptive Intelligence Technology where Microprocessors with IntelliSense automatically sense the hardness of the water and skip the RO process if the TDS is not high. This retains the essential minerals in the water, and you get safe and healthy water for you and your family. Also, it means lesser wastage of water and prolonged RO filter life.

3. Activated Carbon Block Design

Whirlpool Activated Carbon Block

Unlike other brands, inside the Whirlpool Purasense RO water purifier’s pre & post-carbon filters, the activated carbon blocks are tightly packed, rather than being loosely aligned. This leads to a higher contact time between water and activated carbon as it passes through this stage of filtration, which means higher purification level and better efficiency of the filter.

4. 9-Stage Water Filtration (RO + UV + UF + TDS)

Whirlpool has left no stone unturned in providing the multiple levels of water purification in this model. 9-stages of purification level is rare to find in the Indian market, and Whirlpool has provided with every kind of filtration level a consumer searches for in an ideal water purifier. Stages of water purification are as follows:

Highlights of our Experience with Whirlpool Purasense RO Water Purifier

The effectiveness of a water purifier is checked by what output level of TDS is the water. In my testing, with an input source of 140-150 TDS level of water, the output TDS was in the range of 20-30 which is excellent, and since the count is above 20, it probably shows the presence of calcium in water which is getting counted in the TDS count by the TDS meter.

Should You Buy It?

Decide for yourself. Believe it or not, a water purifier is a necessity, and there’s no shortcut to water purification. You never know what quality of water you might get tomorrow? In general practice, every three months, we must clean our water purifier pre-filter because the kind of impurities and pollution it captures is unimaginable. You can’t imagine drinking water without passing it through a water purifier. Also, boiling water is not a 100% protection; boiling cannot remove the dust or impurities; it can only kill the germs and bacteria. And when it comes to you and your family’s health, no one wants to take a chance or settle for anything other than the best.
