This is my second purchase of this product from this seller. Due to the high iron content in my water, I currently have to change the filter every three weeks. The product works just as well as the Whirlpool and Filtrete brands that I have been buying for years. When I first purchased this product, I was specifically looking for filters with 33 grooves, which is the same number of grooves found on Whirlpool and Filtrete brand filters. I realized that the more grooves, the better the filter. I looked at the photos of the different options offered and counted the grooves. This product picture had 33 grooves but when the order arrived they only had 23 grooves. I was disappointed with the misrepresentation, but after using all six filters I found that they worked no differently than the 33 Groove filters.
