The filter is identical to the one proposed by Whirpool, both on their website and via their resellers. The only difference: the price halved> to order multiple both to cushion the postage. I recommend it to everyone, it must be changed, in principle every six months. In another, it was during a tornado that our private electricity during 12H, that our American fridge broke down, the technician who spoke, had not this filter as replacement parts, advised me to go on your site. This happened in Province: we see the difference with the Paris Region !!! Good time to send
