That would make a huge difference in expected performance/side-by-side comparisons.
I'm not sure how the micron rating is used here. That might be a call to the sales dept.
What is good is that these are so easy to use it is hardly a chore to clean them out every three days since all you do is turn them inside out, clean with a spray from the garden hose and place back in the sump.
