SOME FILTER BOXES HAVE RANGES, YOU NEED TO SELECT A VALUE IN BOTH BOXES TO NARROW THE SEARCH
for example if you measure 51mm, Filter 'From' 49 and Filter 'To' 53. This way you can get anything that is close to the required measurement. If you only select 'From' then anything above that value will be displayed
