Jandy CL 340 Pool/Spa Filter Set (4 Pack)

They look to be the same filters as what my pool came with 3 years ago. Not that it may affect usage, but I did notice a few differences.1. The end pieces seemed like a harder plastic, the original filters seemed have a softer plastic. Not sure if that matters.2. The filter media seems slight thicker on the original filters.3. The psi is a little higher on these new filters, does that mean they don't flow as much?

Very happy I purchase this lproduct.Good to know I'm not using harmful ingredients!Would have given 5 Stars if it stayed in place better.
