3A molecular sieve is a potassium-form A-type zeolite adsorbent with an effective pore opening of approximately 3 angstroms. It adsorbs water and other small polar molecules while excluding most hydrocarbons, which makes it a standard choice for deep drying of gases and liquids.
4A molecular sieve is a sodium-form A-type zeolite adsorbent with an effective pore opening of approximately 4 angstroms. It readily adsorbs water, carbon dioxide and other small molecules, and is widely used for general-purpose drying and purification of gases and liquids.
5A molecular sieve is a calcium-form A-type zeolite adsorbent with an effective pore opening of approximately 5 angstroms. It adsorbs normal (straight-chain) paraffins and small polar molecules, and is used in separation and purification duties where selective adsorption is required.

Notes on molecular sieve selection, loading and product care.
Air separation units remove water and carbon dioxide from air before it is cooled, because both would freeze solid inside the cold box. This article explains why.
Most adsorbent problems blamed on product quality start during loading and storage. This article covers the storage, loading and sealing habits that protect performance.
Molecular sieves are named by pore size. This guide explains what 3A, 4A, 5A and 13X can and cannot adsorb, where each grade is used, and how to choose the right one.
