I have used this filter and find this to be a very good filter for this cartridge type.
These little filters cannot remove everything from your refrigerator water system, you'll need a high quality reverse osmosis system for that.
Recently I found a website* that lists the actual impurities that this 4396510 filter removes, I quote:
* 99.35% of Lead at pH 6.5
* 99.31% of Lead at pH 8.5
* 96.70% of Mercury at pH 6.5
* 91.20% of Mercury at pH 8.5
* 99.93% of Asbestos
* 96.30% of Benzene
* 99.70% of P-Dichlorobenzene
* 99.99% of Cysts
* 85.60% of Atrazine
* 92.96% of Toxaphene
* 93.06% of 2,4-D
* 97.60% of Chlorine
* 99.30% of Turbidity
* 99.90% of Particulates (Class I)
As with all built-in refrigerator water filters, the 4396510 does not remove Fluoride.
The 4396510 cartridge is tested and certified by NSF International to meet or exceed NSF/ANSI Standards 42 & 53.
The other model cartridge (4396508) does not filter quite as much as the '10' model.

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.
We bought the OEM at Sears for about $44 + tax, but returned it the next day when we found these here at a much better price. and ordered them. They came right away and seem to be ok. BUT--on the box where the installation instructions are there is NO reminder to take off and save the end cap from the old filter. Naturally I forgot, removed the old one and put the new one in. It did not look right, I saw what the problem was and managed to remove the new one, put on the end cap, and reinstall it. No harm, no foul, but just be careful when you install one of these. Also there was only 1 sticky to place in the refrigerator to let you know the installation/replacement dates---there should have been 2, one for each filter.
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.
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).
I have a Kenmore side-by-side refrigerator and have used sveral brands of replacement water filters.
I have used Kenmore 46-9010
I have used WaterSentinel WSW-1
I have used Whirlpool 4396508
(the filter being rated is the newer version of the older filter above)
The Whirlpool #4396510 is the newer version and does not need to have a gallon of water run through it after installing it (even though I did flush a liter or two through it to get the air out of the system and to ensure no leaks).
What I like about this filter is the following:
1) NSF certified/tested to tests #42 and #53 (not all filters are tested at all or do not test to #53).
2) This filter claims to removes cysts (whatever they are), but again not all filters claim to remove whatever this is... so it must be a capability that this filter or the tests above meet and allow for (again, other brands do not state, so they must not)??
What I like, is that this filter is a name brand filter for $25.00/ea, tested and certfied, ships free as it meets the minimum shipping amount due to being a 2-pack (so I have year's worth of filters since I replace every 6 months as required)... and compared to the lower price of the cheaper filters available, I do not mind paying an extra $7.00/ea for the benefits mentioned above.... for me it is worth it!!!
As mentioned above, I have purchased and used various replacement filters that all seemed to work, but for the money, this filter has all the right specifications, certifications and that it is the new/updated part number to the Whirlpool filter #4396508 which does not require a gallon of water to be run through it flush out any loose carbon particles.
