Buying Guide – Best UV Water Purifiers in India

A UV water purifier falls under the absolute necessity of a household. So we need to know everything about a water purifier before we move on to invest in one.

We need to consider about our personal needs and requirements like kitchen space, the taste of water we prefer and also the kind of kitchen and house we have.


After clearing out the personal requirements, we need to know everything about UV water purifiers, their purification process, filters, how size, shape, and style can affect the entire kitchen scenario, LED indicators, etc.

It is very important to know all the features and characteristics of a water purifier so that we can make the best decision for ourselves.

You do not have to feel scared because we have accumulated all kinds of information regarding UV water purifiers so that you can relax and have a glance through them. So without any further delay, let us check some of the factors we need to look out for before purchasing a UV water purifier.

Factors to consider while buying a UV Water Purifier

1. Water Quality

Some of the pollutants are strong enough to spread and soak in the UV light. This becomes a barrier in the functionality of the UV light because by eating up most of the part of the UV rays, it is deducting the total quantity of UV rays that fights to kill the microorganisms.

Those pollutants, namely manganese, iron, humic and fulvic acid are present in the top layer of the water. Interestingly, some of the microorganisms are coated with suspended solids.

Sometimes, it even forms into the shape of floating debris. The purification of this water is only possible when these are removed in the entire filtration procedure.

So, you should know about the various pollutants and toxins that are present in the water because this knowledge will help you decide whether you would need to attach an additional pre-filter.

The factors include:

  • Hardness should be less than 120 ppm
  • Iron content should be less than 0.3 ppm
  • Manganese content should be less than 0.05 ppm
  • The state of turbidity should be less than 1 NTU
  • Tannins should be less than 0.1 ppm
  • Level of UV transmittance should be greater than 75%

2. Flow Rate

Flow rate actually means the total water usage in a day. This is quite obvious that different households will have different water requirements as the total number of members vary. So if one particular household has a large family, their quantity of water intake will be huge and vice versa.

So check the water flow rate in the specifications section that will match your family requirements.

There is an easy way to figure that out. Have a rough idea about the quantity of water all of the members of your family drinks every day. And always go for a water purifier that will offer more quantity of water than your actual estimation.

3. Longevity of the UV Bulb

The UV lights may be durable but when they will stop working after a certain point in time, you will have to change it.

So, it is a significant factor to be aware of so that you know how many times you will have to change it and how much it will cost you and be assured whether you are investing in the right one or not.

You need to count this cost along with the water purifier’s total MRP. It depends on product to product how often you will have to replace the bulb. It may be after a few months and some may demand a change after a year or so.

So your calculation here is pretty simple. You need to go for a product that will offer you greater longevity of the UV bulb so that you get to save money at the end of the day and do not have to put in a lot of effort to maintain it.

4. Tank Capacity

This is one of the most important factors that you must keep in mind while buying a UV water purifier. Most of the water purifier does not have a lot of storage. You need to go for a water purifier that will continuously provide you pure and freshwater even when there is an electricity cut.

5. UV fail indicator

This also falls under one of the most important attributes of a water purifier. A UV lamp is the most important component of UV a water purifier. It has a very important role to play in the purification process.

And ofcourse, it is not possible to find out about fact if the UV lamp is working or not. By chance if the UV light stops working, it will no longer be able to do its job, that is, the purification of water.

So if the water purifier has a distinctive LED indicator for the UV fail alarm, we can know if there is something wrong with the UV light and if it requires a change from beforehand. This feature will assure you that you are drinking safe and pure water every time.

6. Wattage

A water purifier requires a certain level of wattage so that it achieves the perfect level of the UV-C generation and its short wave radiation. A water purifier will work smoothly in a regular wattage value between 55 W to 120 W. Sometimes, it can demand even more.

7. The Mode of Operation

A water purifier, which you will be using daily, should be easy to operate. The water purifiers that offer the automatic feature are really convenient because the UV light will predict when the machine is not being used currently and will shut down immediately.

This is extremely helpful as it aids in increasing the lifespan of the UV lamp and thus, the entire machine. The water purifier should be less complicated and it should be able to operate completely with just a single touch!

8. Installation Process

This factor will completely depend on your preference. So you need to get yourself a water purifier that will give you the benefit to fit it anywhere you want, whether hanging on the wall or just simply placing it on a table. You can even go for the water purifiers that are very specific in the installation process.

Installation is a professional job and you will need to call in professionals to fit it inside your kitchen or anywhere you want. So just check whether the company will provide you the privilege to install the machine free of cost.

9. Certification of Assurance

Very few of the water purifiers undergo a certification process. So it is best suited to buy a water purifier that is well-reputed and trusted by majority of the Indians.

Whether you are going for an unknown brand or a known one, you need to do your homework and research about the purifier as well as the company and most importantly, check the kind of reviews it has received from the existing customers.

10. Customer Service

This factor varies from company to company and it is always advisable to go for such companies that are well known for the kind of customer service they offer as sometimes, it can be pretty costly.

So before finally purchasing a water purifier, make sure to check the reviews given by the customers because you will get to know about the kind of problems the water purifiers had and whether the insurance or warranty will have those problems covered.

So, see if the company will give you honest and full support if you face such kind of similar problems after purchasing it.

11. Extra Features

The extra features include the LED indicators that can let you know about the current status like power, purification, etc; the touch screen, the smart app feature, flow meter, etc. These can be extremely helpful and makes a UV water purifier convenient as well!

12. Price

Usually, the UV water purifiers come in a price range between Rs. 5000 – Rs. 20000. Do not fall prey to the cheap price because that water purifier might not have the essential features and can be of very bad quality.

The main point is price does not determine the quality of a product. You should always check its features and how strong the product is.

13. Warranty

Warranty is an absolute necessity for a machine like this so that you can get essential service from the company if there is any problem with the water purifier.

Certain companies even offer a warranty period of over 4 years. Also, make sure to check the various services they provide under that period.


Components of UV Water Purifier

A Reactor Chamber

This component has the UV lamp and quartz sleeve in it. Its main job is to manage the water that flows inside the system. The material used to build a reactor chamber is stainless steel while some companies may use plastic as well.

UV Lamp

The UV-C radiation that is required for the purification process is generated by the UV lamp. It has a small amount of mercury that helps in forming the UV rays.

The lamps have a filament inside it that produces electricity in order to heat the mercury that will result in evaporation inside the lamp. This evaporated mercury contributes in forming the UV rays by creating electrical arcs and then the purification starts.

Quartz Sleeve

It is cylindrical in shape and is made up of quartz glass. It basically prevents the UV lamp from coming in direct contact with the water surface.

The UV rays pass through this sleeve in order to reach the water. Clean it at the time you change the UV lamp because the pollutants might form a layer on the surface. This will help in the smooth functioning of the purifier.

The Controller Unit
