When it comes to water filters, it's important to understand that not all brands are created equal. Second Nature's It Matters filter, for example, is certified to meet NSF 53 and 42 standards, and is able to leak more than 99% of lead from drinking water. While the initial cost of a cheap refrigerator water filter may be lower, the higher quality, performance and safety standards of original factory filters are worth the extra cost. When it comes to the quality of the filter paper, carbon media will take care of most of the filtering, and the role of the paper is to keep the carbon in the filter.
The channels at the bottom are more likely for column structure rather than flow. I work in a field related to this and can say that the difference between these filters is negligible and not worth the cost. The only thing that really matters when it comes to refrigerator water filters is removing chlorine odors and some unpleasant flavors in drinking water, which is probably most of what anyone in the United States needs from municipal water.

The most basic certification a refrigerator water filter can obtain from NSF certifies that your water filter improves both the look and overall taste of your home water supply. However, there are several NSF certifications that your refrigerator water filter was tested for, and they all mean slightly different things. For example, a PureSource filter can earn a total of three NSF certifications if it's large enough to filter 200 gallons. With a lead-free food-grade material construction and a top-of-the-line coconut charcoal block and three-layer filtration system, you can count on this filter to provide clean, healthy drinking water for you and your family. In many cases, taking a risk with generic brand filters is worth it as they tend to be much cheaper than OEM products. However, it's important to remember that when it comes to water filters, you get what you pay for.
Higher quality filters may cost more initially but will save you money in unexpected repairs and their costs down the line.
