Just received a Baldwin PA4151 air filter and took it out of the box to find adhesive applied poorly dripping into the pleats somewhat distorting the pleats. I emailed Baldwin to show them the quality they provided on this filter. Never had any issues with Baldwin in the past, maybe they’ll replace it, well at least I asked for a new one. As I told them, I’ve bought many Baldwin/Hastings air filters and oil filters over the years and never had an issue.
