3M™ Zeta Plus™ MH Series are a family of advanced, dual zone depth filters designed to provide optimal clarification and prefiltration in Food & Beverage applications. The Zeta Plus MH Series filter design consists of two distinct layers, or “zones” of filter media with the upstream zone more open than the downstream zone. This structure enhances the contaminant holding capacity of the filter media, since larger particles are trapped in the upper zone of the filter media and smaller particles are trapped in the lower zone, reducing premature plugging and extending service life. The two filter zones can be independently selected and combined to optimize performance.
We manufacture Zeta Plus™ MH Series Filter Cartridges in 8-, 12-, and 16-inch diameter sizes, providing filtration surface areas from 2.8 ft² to 42.2 ft² per cartridge. With a combination of depth filtration and electrokinetic adsorption, our cartridge provides efficient haze and particle reduction. Larger particulate and hazes are mechanically entrapped in the depth of the filter, while negatively charged particles, such as bacteria, yeast, and submicronic hazes are adsorbed to the positively charged Zeta Plus MH Series filter.
