If your water purifier uses ultraviolet (UV) light to kill bacteria and viruses, it’s important to check the UV lamp regularly. A UV lamp typically lasts about one year with proper maintenance. Here’s how to check yours:

First, unplug the water purifier from the power outlet. Then, open the UV chamber and inspect the lamp. The bulb should be clear and free of any cracks or damage.

If you see any damage, it’s time to replace the bulb.

  • The first step is to identify the UV light in your water purifier
  • This can usually be found near the top of the unit, and may be labeled as such
  • If you cannot find it, consult your owner’s manual
  • Next, locate a power source for the UV light
  • This will typically be a small electrical box near the bottom of the unit
  • Once you have located it, turn off the power to the unit
  • Now that the power is off, open up your water purifier so that you can access the UV light
  • Be careful not to touch any of the exposed electrical components inside
  • Using a clean cloth, wipe down all of the glass on the UV light bulb
  • You want to make sure that there is no dirt or debris obscuring the light
  • Once you have cleaned off the bulb, turn on the power tothe unit and allow it to run for a few minutes
  • Then checkthe water coming out ofthe taps in your home to ensure that it is safe to drink

How Do I Know If My Uv Light is Still Good?

If you have a UV light that is more than a few years old, it is probably time to replace it. Here are some ways to tell if your UV light is still good: 1. Check the output.UV lights lose their intensity over time, so if you notice that your light isn’t as bright as it used to be, it’s probably time for a new one.

2. Look for signs of wear and tear. If the glass on your UV light looks cracked or damaged in any way, it’s time to replace it. 3. Check the expiration date.

Most UV lights have an expiration date printed on them somewhere; if yours has expired, then it’s definitely time for a new one!

What is the Life of Uv Lamp in Water Purifier?

UV lamps are used in water purifiers to disinfect water. The life of a UV lamp in a water purifier depends on many factors, including the type of UV lamp, the amount of use, and the quality of the water being treated. Most UV lamps have a lifespan of around 9,000 hours.

How Long Does a Uv Lamp Last?

A UV lamp is an important tool in fighting bacteria and viruses. But how long does a UV lamp last? The answer depends on the type of UV lamp and how it is used.

For example, a germicidal UV lamp used in a home air purifier will last about 6 to 12 months with proper maintenance. But a high-intensity mercury vapor UV lamp used for water disinfection can last up to 13,000 hours! Here are some tips to extend the life of your UV lamps:

-Change the filter regularly according to manufacturer’s instructions. A dirty filter can reduce the output of a UV lamp by up to 50%. -Clean the inside of the unit (including the reflector) monthly with a soft cloth dampened with water or alcohol.

This will remove any build-up of dirt or dust that can absorbUV light and reduce its effectiveness. -Be sure to position the UV lamp properly so that it has good airflow around it. This will help keep it cool and prevent premature aging of components.

How Can You Tell If a Uv Bulb is Blown?

If your UV bulb is not working properly, there are a few things you can check to see if it needs to be replaced. First, check the power supply to make sure the unit is getting power. If it is, then check the connections to ensure they are secure.

Next, inspect the bulb itself. A blown UV bulb will usually have a blackened or discolored appearance. If the glass envelope around the bulb is cracked, that is also an indication that it needs to be replaced.

Finally, test the bulb using a multimeter. Set the multimeter to read resistance and touch the probes to the ends of the bulbs wires. A reading of infinity indicates an open circuit, which means the bulb has failed and needs to be replaced.


If your water purifier has a UV lamp, it’s important to check it regularly to make sure it’s working properly. Here’s how: First, unplug the unit from the power outlet.

Then, remove the UV lamp from the unit and inspect it for any damage. If there is any damage, replace the lamp. Next, clean the end of the UV lamp with a cotton swab dipped in alcohol.

This will help remove any buildup that could prevent the UV light from working properly. Finally, reinstall the UV lamp in the water purifier and plug it back into the power outlet.
