When to Change Your PUR Water Filter


A PUR filter’s life depends on its type, but generally, it needs to be changed every two to three months. Nevertheless, there is no need to guess with PUR filters. They have their own advanced indicator light.

The light indicator has three colors:

  • Green – The filter is in perfect condition
  • Yellow – It is time for a replacement
  • Red – The filter is no longer filtering the water

After changing the filter, the indicator light will automatically turn green.

What Causes PUR Water Filters to Go Bad


The primary factor that affects the longevity of a PUR water filter and when to change it is the amount of water the household uses. Other elements that necessitates that the filtration device is to be replaced before two to three months are the following:

Water Quality

The degree of pollutants in the water of your area affects how hard your filter has to work. Sometimes, high levels of pollutants exceed the maximum capacity of a water filter. As a result, the device works insufficiently.


Erosion in some places causes sediments to build up in the water supply. Thus, it is best to treat the water from the deposit before filtration. Otherwise, the sediments will clog the filtering device and cause it to stop working. I recommend you consider a sediment filter. It is specially designed to handle this problem.


Excessive amounts of iron are toxic not only to humans but also to your water filter. There are heavy metal irons that cause hardness in the water. It messes with the filter’s work, which might lead to errors.

Over Usage

There is a set amount of water volume that each filter is capable of dealing with. If a household consumes large amounts of water in a short period, your filter will be exhausted and no longer sufficient to work effectively. For situations like this, you should refer to the number of gallons the filter is able to accommodate rather than the duration.

Types of PUR Water Filter

PUR has several types of water filters, and each has a distinct feature. If you want to find a PUR water filter for your home, this list will help you select a suitable one.

Faucet Mount

Filtration Pitcher

You can enjoy cold and filtered water with this convenient water filter. The filter cartridges require no set-up and very little maintenance. In addition, the slim design can fit in small or crowded refrigerators. Make sure to opt for one with a filter indicator light that will tell you when to replace the filter.
