Refrigerator systems feed the inbuilt water dispensers and the ice maker compartments. These include Whirlpool and KitchenAid, among others.

The refrigerators have two types of filters; the twist-on filter and the push button. Changing the filters for the push button is different from the twist on the style.


  • Twist-On Filters

Twist-on water filters come in front of your refrigerator, just behind the bottom grill. They may also appear inside the fridge in the upper right or the bottom corner of the refrigerator chamber.

 How often do you have to change PUR water filters?

At this joint, you have all the steps that you need to change your Pur water filters. That includes a pitcher filter, dispenser, and your spigot filter. Now, the question is, how often should you change your Pur water filter?

The precise answer to this question depends on several factors;

1. Model Of The Pur Water Filter

The specific type of your Pur water filter determines how often you will change the filtering unit. We have four models of Pur water filters.

  • Pur Spigot/Faucet/Tap Water Filter

A PUR spigot water filter works on approximately 100 gallons of water in two to three months.  

On the filter housing, there is an indicator to alert you whenever your filter needs a replacement.  

  • Pur Pitcher Filter

If you have the PUR pitcher filter, you will be filtering approximately 40 gallons of water. That will take you one to two months to work perfectly. It comes to you in the form of a jug to place it conveniently on a countertop.

  • Pur Water Dispenser Filter

A dispenser filter includes a compartment with a filter where you pour in water for purification. The unit is more significant than a pitcher and comes with a tap to pour water into your cup. They are also pricier than pitchers but function similarly.

  • PUR Refrigerator Filters

A Pur refrigerator filter comes with an easy-fit feature that allows you to fix the unit at the bottom of your refrigerator. Its design will enable you to purify more gallons of water than the pitcher and dispenser models. 

The filter works effectively on 100 to 200 gallons within six months. As you notice, the models last longer than the faucet, dispenser, and pitcher filters.   

2. Frequency Of Use

Suppose you have a smaller household of, say, two persons, the frequency of use is less than a household of five. Your pitcher water filter will last longer than the average two months as it filters less water in a day.

For instance, if you had several guests residing in your home for a week or two, the frequency use increases, meaning that your pitcher filter may take you only a few weeks to that you use.

3.       Level Of Contaminants

High levels of contaminants in your tap water clog your filter quicker than the average timelines. That means frequent replacements in less than time indications on your Pur water filter. On the other hand, if your tap water is cleaner, your water filter will last longer than the spelled timelines.

How do I know when my PUR water filter needs changing?

The best thing with PUR water filters is that they have an indicator light that takes away guesswork whether they still have a life or they get worn out. Depending on the type of filter, the color indicator comes at different positions. 

A pitcher and a dispenser filter will have a light display on the top cover/lid. The faucet filter light display comes on the side. The refrigerator type of filters has the indicators at different positions depending on the model.

The lights are usually green, yellow, and red or no light at all. Each indicator light has its meaning. A green indicator light tells you that the filter is functioning appropriately and does not require replacement.

A yellow light is an alert that your filter is halfway filtering and will require replacement any time soon. If it begins flashing, that’s the perfect time to acquire and install a new replacement Pur filter.

A red alert shows no filtration or purification taking place in your filter system. Drinking or using the water from a red-light PUR filter equates to drinking unsafe water straight from the tap.

When you replace the worn-out filter, the yellow indicator light will not return to green unless you press and hold the reset button. After five moments, you will see the green indicator light, meaning that the unit is working perfectly.
