Not sure what to make of this filter's fewer pleats
This filter has about 1/2 the pleats of prior filters I've used.  With fewer pleats there is less surface area for filtering so I suspect it will get dirtier sooner and I will have to change filters more frequently. Also, I have no idea how that affects performance. Maybe I should have looked at the picture more carefully because it is an adequate reflection of number of pleats though spacing it not as uniform. This filter was in a nondescript box with the filter itself covered in plain plastic.  There wasn't any info on manufacturer or Merv rating. Maybe contractors are their most likely consumer?  I would feel more comfortable being able to read about the product.
