Product review (5 stars): Only buy this Whirlpool brand! Great product
Excellent product. **Do not waste money on any other brand**. This OEM Whirlpool Brand filter works great!!! Don't be fooled by other brands fake reviews. Just pop this 1 in, run a few gallons of water through it to flush it out and Purge the air and your ready to go.

I thought i could get away buying the cheaper off brand because it had good reviews and i paid the price.  The 5 star reviews had to be fakes. The water had a terrible chemical taste even after running several 5 gallon buckets worth of water.  .
