4A molecular sieves to remove H2O from EtOH???

Hopefully a simple question to answer. I am aware that 4A molecular sieves work well to remove water from acetone but can this size work to remove water from EtOH as well or does one have to use 3A molecular sieves? Thank you!!!

you can use 4A to remove water vapour, but the pore size is not selective between ethanol and water. 3A should be used

3a for ethanol
