PUR has developed a practical, simple-to-use, and highly effective home water filtration system. PUR Water Filter gets rid of these harmful substances like chlorine. Minerals and microbial cysts are also removed by PUR.

Besides performing its primary function of filtering contaminants, PUR comes with other smart features such as an LED indicator light.

The inbuilt LED indicator is a very useful tool that helps you know when you need to replace the filter cartridge. It tracks the cartridge’s life and when the filter’s life is over, it notifies you to replace the cartridge. 

Given that it tracks how long the filter was in the pitcher, the LED indicator is an ingenious feature.

What are the indications that PUR water filter is working correctly?

Typical signs that your PUR water filter is working properly include the following:

  • If a red light on the LED indicator blinks, it’s time to change the PUR filter.
  • Replace the filter if the pH falls outside of the usual range of 6.5 to 7.5.
  • Additionally, the conductivity and TDS need to be examined, and if they are outside of range, you need to change the filter cartridge.
  • Bad odors, sediment buildup, and slow filtering are typical indicators that filters and pre-filters are malfunctioning.
  • If the water dispenser frequently clogs or has a poor water flow, it might have a filtration issue.

Why does my PUR water filter light not work?

However, PUR water filter are not perfect, and they can sometimes have problems. One of these problems could be the LED light indicator.

The following are a few of the most typical causes of flashing red light and potential troubleshooting techniques you could use:

1. How to Set Up PUR Water Filter

The possibility exists that the new filter is not completely seated in the housing, which makes the indicator start giving a false warning. 

Verify that you installed the filter correctly in the water filter. If it’s not correctly installed, it may be necessary to press the filter into the housing until it snaps physically.

It is easy to set up the PUR water filter cartridge.

Simply follow these steps:

  • Remove the old cartridge by turning it counterclockwise after releasing the stopper.
  • Next, take out the new filter and give it a 10-minute soak in cold water.
  • Next, thoroughly rinse the pitcher after hand-washing it.
  • After washing the replacement cartridge, screw it into the pitcher with a clockwise motion to secure it.
  • Finally, pour cold water from the tray into the pitcher.

2. How to Reset the PUR Water Filter

Consider resetting your PUR water filter. To do so, press and hold the reset button for five seconds. If the light turns back on after a few seconds, your filter is operating correctly. You might also turn off your PUR Water Heater and wait 30 seconds.

Turn it back on and let it run for 60 seconds before turning it off again and waiting an additional 30 seconds. Repeat this process until your system resets itself.

3. How to Clean a Clogged PUR Water Filter

Another issue may be that the PUR water filter is clogged. If this is the case, try running the filter for a longer duration to remove any debris that has accumulated. If everything else fails, you may physically disassemble and carefully wash the water filter housing by hand and rinse well.

4. How to Replace Your PUR Water Filter

A new water filter may be required if the blinking remains after following these recommendations. If you have trouble finding the right replacement for your filter, check out our list of compatible filters here.

5. Contact Customer Care

Probably there’s too much dirt on the filter screen which might cause the light to turn red. However, if the indicator stays red, you may contact PUR customer service for assistance.

Their customer service seems to be second to none, and they seem to be willing to go the extra mile in order to ensure that each customer is satisfied with their purchase.


How does the PUR LED indicator work?

PUR filters water using an active carbon filter through a process called adsorption.

The mechanism of adsorption occurs when solid particles become attached and start collecting onto the filter surface.

The active carbon has pores that are small enough to hold the pollutants, but large enough to allow water molecules to pass through thus the contaminants are then removed from the water stream.

When the pollutant molecules are bound to the filter, they are removed from the system and do not circulate through the rest of your filter cartridge.

The amount of pollutants that are prevented from passing through depends on other factors also such as temperature, flow rate, and pressure.

Thus, through adsorption, the PUR water filter makes it possible for water to pass through while other materials which are pollutants stay behind on the filter’s surface.

When there is no longer any filtering of the water and the pores have become clogged thus no contact between the pollutant and the pores of the filter, the filter is said to be “dead.”  Thus the indicator will turn red to let you know, it’s time to replace the filter cartridge.

PUR Water Filter Blinking Green

An indicator with a green light means the water filter is working as intended and its effectively filtering the water you’re drinking.

This is one easy way of knowing that the PUR water filter is working effectively.

Your water filter should be blinking green. If you see a steady green light, that means your water filter isn’t functioning properly. You should contact PUR customer care to make sure they’re able to provide you with a new one.

If your filter has stopped blinking green completely, the problem could be the battery. You are thus recommended to replace it immediately.

PUR Water Filter Blinking Yellow

The LED indicator of the water filter begins to blink yellow as the water filter becomes less effective.

The indicator is blinking yellow, indicating that the water filter is getting clogged and its becoming less effective in filtering the contaminants.

This is a clear indication that you should replace your current water filter soon.

PUR Water Filter Blinking RED

The red light is a warning that your water filter needs to be replaced. The water filter has been clogged for some time and you should replace the filter immediately.

How to Replace PUR Water Filter Cartridge

Water filters are sensitive to contaminants and can break down over time. This is why it’s important to change your filter once when it starts blinking red or after 3 months.

It is easy to replace the PUR water filter cartridge.

Simply follow these steps:

  • Remove the old cartridge by turning it counterclockwise after releasing the stopper.
  • Next, take out the new filter and give it a 10-minute soak in cold water.
  • Next, thoroughly rinse the pitcher after hand-washing it.
  • After washing the replacement cartridge, screw it into the pitcher with a clockwise motion to secure it.
  • Finally, pour cold water from the tray into the pitcher.

After replacing, if the indicator does not start blinking green, the PUR pitcher filter light could be in standby mode.

Simply hit the reset button and hold it there for five seconds before letting go. The light will be automatically restarted.

If that doesn’t work, and you still see the red light flashing, then it means that there is something wrong with your filter or with how it was installed. At this point, it’s highly advisable to stick to the manufacturer’s instructions.

You can replace your old filter by hand-washing it with vinegar and letting it soak overnight in cold water. This is an easy way to fix any problems with your current filter without having to purchase a new one.

The only downside is that you don’t know exactly how long it will take for your filter to work correctly again after changing out the cartridge yourself.

If you live alone, it is advised that you change the filter every 100 gallons or every 3 months. If you have a family, at least once a month, and once a month if you share a home with a significant other.
