What to Consider While Buying UV Water Purifier

The water usage or requirement of each household is different. Even the water resource for each house is different. Thus, to help you buy a UV water purifier that meets your requirements, here are the most important factors that you should check for.

1. Check water quality at home

There are some contaminants that can scatter or absorb the UV light. This affects the transmission of the UV rays through water, thereby reducing the amount of UV radiation that reaches the microorganisms.

These types of contaminants are generally found in surface water supplies that include manganese, iron, fulvic and humic acid. Hence, in such cases, disinfection with UV is effective when the filtration process removes these contaminants.

Some microorganisms are also protected by suspended solids or shadow of diet, or in some form of floating debris.

Thus, it is very important to know the types of contaminants present in the water so that your UV water purifier works effectively. There are some parameters that the water must meet. If not, you will have to install a pre-filter.

Some of these parameters are:

  • Hardness < (less than) 120 PPM (parts per million)
  • Iron < (less than) 0.3 PPM
  • Manganese < (less than) 0.05 PPM
  • Turbidity < (less than) 1 NTU
  • Tannins < (less than) 0.1 PPM
  • UV Transmittance > (greater than) 75%

2. How good is the water flow rate?

When it comes to water usage, the requirement of each household is different. For example, the water consumption by a family with 1 or 2 members is much lesser than the consumption by a family with 4 or 5 members.

You should select a water purifier that offers a flow rate that is suitable to meet your water requirements.

To figure this out, take an estimate of the water consumption at your home and then buy a purifier that exceeds the number that you have calculated in the flow rate.

3. What is the lifespan of bulb?

Even though most of the UV bulbs last for a very long time, they don’t last forever and need to be replaced at some point. Hence, it is very important for you to figure out how often will you have to replace the bulb and how much will be the replacement cost.

You can include this replacement cost in the overall cost of the water purifier. In some purifiers, you will have to replace the bulb every few months whereas, in other units, the bulb works for over a year or more without any replacement.

If you are looking for a purifier that needs minimal maintenance and minimal after-purchase expenditure, we suggest you to buy a unit that features a UV bulb with a longer lifespan.

4. How much storage capacity it has?

The storage capacity of most of the UV water purifiers is not too high. Thus, before buying a unit, make sure that you have a continuous supply of water at your home.

This helps you in getting safe and fresh drinking water every time.

However, if you don’t have a continuous or constant water supply at your home, you should buy a non-electric water purifier.

5. Does it has UV fail alarm?

This is an important feature that is very helpful in the future.

Since the UV light is invisible, It is almost impossible to figure out whether the lamp has stopped working or not. If it has stopped working, the purifier will no longer purify the water. The UV fail alarm feature notifies you beforehand whenever there is a need to change the filter.

It is a convenient feature that lets you drink safe and pure drinking water always.

6. What is the wattage?

To generate an accurate amount of UV-C and short-wave radiation, the ballast should be of certain wattage. For most of the houses in India, a 55 W, 120 V water purifier system works fine.

7. What is the mode of operation?

Always check if the water purifier is easy to use or not. In purifiers with an automatic mode of operation, the UV bulb automatically turns off whenever the machine is not in use. This is helpful in enhancing the lifespan of the UV bulb and the overall purifier. It also prevents you from spending on a new bulb frequently.

A UV water purifier should be easy to use so that you get the drinking water just with the touch of a button.

8. How easy to install?

It is important to buy a water purifier that can be installed as per your convenience. While some water purifiers need to be wall-mounted, others can be placed on a table counter. You can buy the model as per your preference.

Installation of the water purifiers is not an easy task and is better if it is done by professionals only. Make sure that the brand provides a free and quick installation service to you.

9. Does it has certifications?

The water purifiers generally don’t need to pass a certification process. Hence, it becomes even more important to buy it from a reliable and reputed brand.

If you are opting for an uncertified water purifier, make sure that you do enough research from your part and see if the brand is good and if it has positive reviews from the customers or not.

10. How good is customer support?

It is always a great idea to buy a water purifier from a brand that provides excellent customer service as it is a costly investment. Before buying a particular model, go through the reviews of the users to figure out what issues are they facing and are these issues covered under warranty. Also, check if the brand is helping the users in dealing with their common issues.

11. What additional features available?

One of the most common additional features that you should look for in a water purifier is the LED indicator that notifies you whenever the filter needs a replacement. Some brands even offer a touchscreen display, flow meter, and a shut-off valve that can be equally useful.

12. Is the price within budget?

The UV water purifiers are easily available at a price range of Rs. 5,000 – Rs. 10,000.

We suggest you to not fall in the trap of cheaper units as they might not offer the best results. This doesn’t necessarily mean that the costliest models are the best.

You should check the pros and cons of each unit properly and then make a decision, keeping your requirements in mind.

13. What is the warranty period?

Most of the reputed brands offer a manufacturer warranty of 1 to 2 years. It is always better to buy a purifier offering the maximum warranty period. Also, you must check what all services are covered under the warranty.

Advantages of UV Water Purifier

  • Purification with UV is very effective. It destroys up to 99.99% of microorganisms present in the water. UV is comparatively more effective than chlorine against viruses.
  • UV is environmentally friendly and user friendly. UV is a green alternative to chlorine and it has no disinfection byproducts. There is also no risk of overdosing and no potentially harmful chemicals are required.
  • There is no change in the taste and odor. Unlike chemical disinfection methods like chlorine that changes the taste and odor of water, UV does not. The chemical structure of water remains the same after treatment with UV.
  • It is very economical and has a very low power consumption. The initial setup cost is relatively low and as well as the operating costs compared to other methods of disinfection including ozone and chlorine. Hundreds of gallons can be treated at a very low rate in terms of operating costs.
  • Maintenance is simple and easy. Periodic cleaning is required as well as an annual replacement of the UV lamp. The installation of the system is also a simple task.

Drawbacks of UV Water Purifier

  • For the system to effectively disinfect, the water needs to be pretreated to remove debris and dirt. The water needs to be clear and of high quality for a high UV transmittance.
  • As power is required to operate, the system will not work in the event of a power failure.
  • UV can only eliminate the microorganisms in the water. Contaminants such as heavy metals, salts and chemicals cannot be removed with UV, so other methods of filtration are required to ensure the removal of all contaminants from the water.
