Cartridges for flow filters

— cartridges designed for use in flow-through filtration systems – mainline or installed under the sink. They may differ in the degree of contaminant removal and types of filtration (see the relevant paragraphs), however, all such products have a high throughput, otherwise the filter would simply interfere with the free flow of water in the water supply. Flow systems are quite difficult to install – they require special stationary installation without the ability to be transported from place to place.
