How Long Does a PUR Water Filter Last?

We all want mortal filters-this sounds quite funny. However, there are different water filters, and their lasting time varies from one filter to another.

Today, I would like to talk about the water filter. In our previous article, I also tried to show you the different types of filters. Many people use different tastes in buying filters, their design, color, price ranges, etc.


But some of you are confused about the filters’ lasting time. Specifically, I want to share my experience of using and how long a PUR water filter can stay!

How long a PUR water filter can last depends on how much you use it and take care of these filters. But in general, you need to change a PUR water filter every two to three months.

If you buy a second-hand filter, you may need to replace it before two or three months, or it may last longer than you think.

Why Does a PUR Water Filter Smell Terrible?

Just imagine a bottle of water. You have kept water in the bottle for one week before you go out and forget to clean it. Then, after coming from the outside, you went to clean and open the bottle’s cap.

When opening the lid, you will get a smell of rotten garbage or rotten, wet wheat.  If your filter does not get proper airflow, it will smell bad because of bacteria cooking germs inside the filters. And the other reason can be the amount of hydrogen sulfide inside the filters.

Can PUR Filters go Bad? 

Yes, PUR filters may go wrong. All the filters have good and bad sides. Same cases for all the filters. So what can be the reason behind the PUR filters getting bad? But if you take care of these filters, there can be fewer chances to get PUR filters wrong.

  • Quantity of water
  • Iron
  • Overworked
  • Quantity of water: Suppose you live in areas where most of the drain remains dirty all the time, or there can be extra-large particles that can cause problems in filters. For these reasons, sometimes the filter may not be able to clean it.
  • Iron: Iron is one of the essential components of our body, but drinking excessive iron in water can be harmful to your body. Most of the filters can not clean or remove calcium, iron, PFAS or heavy metals contained in water. So it may cause problems when drinking. You may feel like something is stuck in your throat. These types of metals bring hardness in water; your filters may become damaged for this.
  • Overworked: Think about the crayon. If you use it more, it will become small quickly. The more you use, the more it will reduce the power. So the same case for the filter. This is not only for the PUR filter. And if you put water inside the filter without proper measurements, or you might make mistakes while cleaning, the filters can go wrong more than you expect.
