This is for MERV 8 16x25x2 filters. They appear to be high quality filters. I don't have another brand of the same size to compare, so I'll list what I found: There are 13 pleats in total, which seems average for a filter of this size. not always evenly distributed. One of my images shows 1 filter (out of 3) that has the most uneven spacing. This is a minor issue and is likely to have little effect on airflow. The pleats are securely attached/glued to the edges of the filters. I'm sure they won't fall apart with normal use. The filter material is equally dense over the entire length. It has no issues with bumps or quality. The filter is incredibly durable compared to the 1 inch filter filters I've used in the past (which are flexible and will flex over time due to airflow). That's probably mostly due to the 2" filter design, but the extra paper binding and quality of the metal wire also play a role. It's not the cheapest filter you can get, but if you want to play it safe, you won't be disappointed Next time I will most likely get a cheaper one so I have something to compare.
