You reduced the number of pleats by 40% that reduces the amount of surface that filters out the particles. Less surface to filter means it needs to be changed more. Looks to me you are more worried about making a buck than producing a quality product.
Hi - great product however the overall height of the filter is just under (<1/4") the Honeywell filter equivalent. This creates a gap at the top of the filter that allows unfiltered air to pass by. I had to place a filler to close the gap at the top. Future filters should have an extra flap or piece of material to fill that gap.
