The last 1 means 1 inch, there are thicker filters
Please do some searching for yourself, you will find 99% of HVAC contractors recommending to use the plain fiberglass filters only for the 1" versions. Furnace filters are meant to protect your furnace, not filter your air. These high MERV 1" filters are too thin and restrict airflow too much. 2" & 4" filters can get away with it because there is so much more filter media to pass through.
If you have a 1" filter, stick to the fiberglass ones or the lowest MERV rated pleated filter you can find.

Best I've found is a 4 pack ($25 each) on amazon from a generic name company: https://www.amazon.com/gp/product/B07S4HBFTN/
