semipermeable
Lets some through
Semipermeable describes a membrane or barrier that allows some substances to pass through while blocking others.
Cell membranes are semipermeable, letting water and small molecules through while keeping larger molecules out.
The semipermeable membrane filtered salt from the water.
The concept is central to biology, chemistry, and water purification systems.
