Filter cartridges come in various sizes. materials, and designs to suit the needs of different applications. The cartridge you choose might depend upon your media, temperature, purity needs, flow rate, and more. Cartridges are widely used because they pack lots of surface area into a compact filter. They are usually disposable and have to be replaced every so often when the filter is full and causes pressure drop.
There are industrial filter cartridges for process application, but cartridges are also used on jobs as small as home drinking water filtration. Whether it's removing grit or carbon, cartridge filters offer an efficient and cost effective option when it comes to filtering liquid media. Three common filter cartridge constructions are pleated, would depth, and melt blown. Each has its own strengths and benefits, but they are also each best suited for certain types of filtration.
