The beverage filters are intended to increase the resistance and life extension of cider using the mechanical filtration instead pasteurization. Filtered cider is stripped of most living organisms. Although the cider lacks the live yeast after the filtration, but yet it still keeps its taste and variety of nutritious substances. The filtration is principially a mechanical removing of all live yeast from the beverage. Cider once or several times flows through one or multiple filtration layers with different porosity. This process causes the gradual decreasing amount of yeast in beverage.
