I wish there was a 20x30x1 size option 
Does anyone know if these run true to size in regards to thickness? The ones I am using are labeled as16"x25"x1" thick but are actually between 3/4-7/8" thick, which is what I need - a true 1" thick filter will not fit. So if these are a full 1" or more then they won’t work for me.
They are .75 which is 3/4 not a true 1 inch. In filters its nominal not actual.
