Who should get a UV Purifier?

The easiest way for bacteria and toxins to make way into your body is through the water. Tap water may seem clean and safe to use, but the reality is far from that. Tap water is a breeding ground for bacteria and virus. Consuming it can lead to several diseases.

As per the study conducted by, these are the problems we face in our supplied water:

  • It contains harmful viruses and bacteria that pave the way for many water-borne diseases.
  • Pesticides, Lead and other chemicals can easily make their way into tap water

The Indian population is profoundly affected when it comes to diarrhea. There are an estimated 98,000 deaths each year due to diarrhea, mainly resulting from the consumption of contaminated water.

You might think boiling water for 20 minutes is enough to get away from this. However, even then, not all microorganisms get killed. And, cooling it down increases the chances of the water getting infected again.

You can prevent this by investing in a durable and efficient water filter. Your best choice for the business is a UV Water Treatment.

Ultraviolet purification works best in the following scenario:

  • Drinking water infected with biological impurities
  • Water with low TDS of less than 300 ppm

UV water filters have incorporated the latest technological advancements and helps in removing microbes efficiently in the following manner:

    1. Ultraviolet rays kill up to 99.9% germs and other inactive viruses. Their germicidal abilities are unbeatable! It is one of the best water purification treatments in the market.
    2. Use multistage filtering for better Purification:  you can find these purifiers in three, four, and five-stage filtering methods. However, unlike an RO Filter, a UV purifier cannot remove dissolved salts from water.
    3. Using chlorine and other chemical disinfectants can be more harmful due to the fact that these, in turn, create toxic byproducts. UV purifiers, on the other hand, have no harmful residue or side effects.

We’ve chosen the HUL PureIt Marvella based on its immense popularity. The 4-stage purifier comes with a storage capacity of 4 liters, which is pretty convenient! You can use it for TDS up to 2000 ppm.

Price Analysis of UV Purifiers

Although UV purifiers are cheaper than RO purifiers, you might find some stark difference in the price tags. The main reason for this difference in prices are the following factors:

  1. Multistage technologies
  2. Brand
  3. Material quality
  4. Incorporation of other technologies like RO/UF

If you have checked the prices of the purifiers mentioned in the reviews, you might have found that AO Smith is the most expensive one when compared with other cost-effective products available in the markets.

What makes the brand and product worth it is the array of features it carries. No other competitor comes close to the quality and specifications of A.O Smith. Not even AquaSure with its variety of filters!

A.O. Smith is a one-of-a-kind filter with a 5-Stage purification system. Not only that, but it also offers a hot-water option which can be used to brew up a hot cuppa. The temperature choices of 45 and 80 degrees make you reconsider the need for a water dispenser! It also comes with an impressive one-year warranty.

A.O Smith and Blue Star, considering their amazing features, are priced between INR 10,000 and 20,000. We understand that they may not be as cost-effective as the other brands. However, they sure are worth every penny spent!

What’s important to note is that fellow competitor Hindustan Unilever is not far behind. HUL Marvella uses 11 Watt UV Lamp for enhanced safety. It also meets the stringent criteria of the Environmental Protection Agency (EPA), USA. The fully automatic filter does not need reminders to fill up the tank. It does the job on its own!

HUL, along with AquaGuard filters, are cheaper options available in the market for under INR 10,000. While the features may not be the same, they are some of the high-efficiency products on the block.

But the question is; do you really need all these features?

Our buying guide will help you to answer this question.

Things to Look for While Buying UV Water Purifiers

Here’s the ultimate guide to help you make the perfect decision.


UV Filters are an everyday household staple now considering the need for pure and safe drinking water. However, capacity can be a massive problem with these filters as most come without any storage tank.

  1. If you are one to use a large volume of water, especially for cooking, you can consider the A.O Smith filter which holds a capacity of 10 liters. Yes, you read that, right!
  2. Next on the list is the durable filter by Blue Star which has a capacity of 7 Liters. With a purifier like that, you’re pretty much sorted!
  3. You can also consider the Hindustan Unilever Marvella, which is a fully automated filter. It senses when the filter is not full and automatically cleans and stores up to 4 Liters of water!

However, if you are looking for a smart option that is minimalistic and does not take up much space, a small-size filter is the way to go. These come without any storage tank and have an average flow rate of about 2 liters/minute. Waiting a couple of minutes to fill up a pot shouldn’t be a problem, however.

Rate of Flow

You will find many UV Filters in the market that come without a tank and filter out the water when required. In this case, it is essential to pay attention to the time it takes to get a liter or two. However, the best part is, most filters come with an average rate of 2 Liters/Minute.

It means you can quickly fill up bottles and pots, one after the other, all in a matter of a few minutes.

The AquaSure Eureka Forbes and Crystal Purifier are just a few examples of filters with this Hi-Flow Rate.UV water purifiers in India


Inadequate power supply and voltage fluctuation are few issues we face daily. In such a case, most electrical appliances fail to work appropriately. In the case of water purifiers, we really cannot compromise on quality, can we?

For this reason, AquaSure brings you their Crystal Purifier with an in-built voltage stabilizer quality. It allows the filter to work even during fluctuations and low voltage. Who could have thought that?


While filters are an essential commodity, it is also understandable how expensive they can be. All UV Filters require some level of ongoing support or repairing is needed to ensure effective functioning.

But, paying so much and then having to pay regular maintenance charges can be a bit too much. To prevent additional costs, you can invest in a low-maintenance filter. The Hindustan Unilever Marvella is one example of a filter with low costs of maintenance.

Types of Water Filters

A purifier alone cannot do the job of eliminating pollutants. The UV lamp does a great job of killing viruses, bacteria, and other microorganisms. However, it cannot remove metals and other chemicals inhabiting the water. You might need other technologies like RO/UF to get the best results.

For this reason, most models include several other filters to provide you 100% safe and clean water to drink. The A.O Smith purifier, for example, has a pre-filter, sediment filter, silver activated post-carbon and UV Lamp.
