Industrial Grade Multi-Media Filter combines the functional advantages of a pressure sand filter and an activated carbon filter. Multi-Media Filter uses Depth Filtration Technology with multiple media types. Multi-Media Filter utilizes 4-layer media consisting of graded quartz sand, specially sieved fine white sand, activated carbon granules of high iodine value [IV 950] and pebbles at variable proportions to help in reducing the physical contaminants present in the water. Industrial Grade Multi-Media Filter is easy to install and needs less maintenance.
