SUMMARY
CANFILTERS
Base Stats The following table is a chart displaying the data from each brand of filter as stated by the manufacturer. This chart just focuses on 8” short filters used in this comparison. We have also added average prices we found at the time of print. Aren’t we good?

For the scope of this comparison, we looked at one size of filter on one type of fan. Other size filters on other brands of fans will give differing performances, particularly when it comes to airflow. You can view this data as a broad representation of how a brand will perform, but it only specifically shows you how this size performs on this fan.

CAN’s Original filter topped the charts here, but then it is by far the largest (and heaviest) so you would expect that to be the case. From the RAM to the Prima Klima Industry point, the filters were of a similarish size so differences between their air flow drops are more telling. From the Rhino point down, even though the stated airflows are comparable to the rest, their performances all seemed to suffer from simply being too small in length for the job.
