These filters are thicker than my prior filters. I am sure they will catch more impurities than the last ones

The filter looked to be of good construction; it wasn't build with flimsy metal. It was made to the correct dimension and fit the air handler perfectly. I would definitely re-order from discount filters, given the competitive pricing and quality of the filter.
