3M™ Zeta Plus™ VR Series filter media is a family of cellulosic depth filtration media designed to retain contaminants by both physical entrapment and ion exchange absorption.

It is composed of high-area process filter aids embedded in a cellulose fiber depth matrix. During the manufacturing process, a cationic charge modifier is chemically bound to the matrix components, forming a permanent, interconnected, rigid depth filter with positively-charged electrokinetic capture sites. The resulting porous depth filter structure is a tortuous network of absorptive flow channels capable of retaining contaminating viruses through a combination of anion exchange absorption and mechanical entrapment. Cumulative viral titer reduction may also be attainable through a staged two-step Zeta Plus system.
