ISOSURFACE: identifying the connected faces

Dear All,
I have extracted the isosurfaces of variable "A" in a 3D volume data. For a specific value of "A", say A=1, I get three connected series of faces which are separated from each other. In other words, there are three different and isolated regions in the domain where A=1.
I am trying to identify these three regions and save them into three different variables. I would be grateful if someone could give me a hint on how I can achieve this goal.

The domain that I have has noise in it. So, when I plot an isosurface of some value, I get a few little islands in the plot beside the main one. I want to have the biggest isosurface. This may be solved by smoothing but I want to avoid using it as it changes my results.

I had tested this before by defining a tolerance but unfortunately I don't get the results of S.PixelList similar to that of isosurface function.
Can I send you the MAT file? You may find the source of discrepancy.
