This product works great and really makes a difference in the quality of the water we use from our KitchenAid refrigerator.

This product represents great value for money and is etremely easy to install.
The manufacturer recommends changing every 6 months, but I’m sure it’s ‘water quality’ dependent as my filters last at least 12 months (Fort Collins, CO has great water quality).

The filter I bought from Amazon for my Whirlpool refrigerator is exactly the same as the one I purchase for more money at my appliance store.

The Whirlpool version here is definitely worth the price. I bought this NSF Class I (best) certified Whirlpool 4396510 here on Amazon at a slightly higher price than the PUR filter, but I would not sacrifice quality or safety for a slightly lower price.
There is no NSF certification for the PUR filter available on Amazon or on the PUR Web site. That seemed kind of sketchy. Is it Class I, II, or III? Maybe they do not get their products certified.

I have a Kenmore Elite side-by-side refrigerator and have typically purchased the filters directly from Sears for the Kenmore version of this water filter. I found out that my refrigerator although Kenmore, was actually made by Whirlpool. So I searched the internet for the comparable filter for my model refrigerator, ordered it through Amazon saving oodles of money and have been happy with the product.

Replaced my Kenmore water filter with this one for 1/2 the price. Has same specs for removing lead, cysts, etc. NSF certified. Water tastes great. Couldn’t be happier!

Saw cheaper brands, and did comparison research on what contaminants the off-brands filtered vs. the Whirlpool. If you’re concerned about filtering heavy metals and chems out of your drinking water, the Whirlpool “cyst reducing” filter has better filtration specs than the cheaper off brands. Amazon’s price was as cheap as any other place i could find–cheaper than most.

We have a Sears Kenmore refrigerator model number 106.53582300 (made by Whirlpool) that we purchased from Sears. It has the round water filter in the base of the refrigerator that should be replaced every year. Sears sends post cards wanting to sell us a filter for $40 plus shipping. After some research we came across this one for less and it works superbly.
Highly recommended to save money over the Sears option.

The filter arrived quickly and it works great. It is easy to install and the water tastes noticeably better.

The term, “Particulates” refers to particles of rust, dirt, sand, and sediment found in drinking water. Water that contains Particulates is typically cloudy, and as you might expect, tastes and smells “dirty”. By themselves, Particulates are not known to cause any adverse health effects, but they can sometimes carry other harmful organic, inorganic, and microbiological contaminants through the drinking water system.

In general, better filters will remove finer particles. Each filter’s ability to remove particulates is measured against a certain “particulate class”, or particle size.

Class I – 0.5 to 1 micron
Class II – 1 to 5 microns
Class III – 5 to 15 microns

Where one micron is one millionth of a meter or approximately 1/25,000 of an inch.

For example, if a filter is rated to remove “95.1% of Particulates (Class II)”, that just means that it will remove 95.1% of all particles that are between 1 and 5 microns in size
