Description
The HFS filter is considerably higher than the FA filter and contains nearly 50% more filter medium. It provides more contact time due to the higher filter bed, resulting in a better filtration and flocculation process.
The HFS 15 filter and higher-level models are constructed with a larger transparent filter lid and contain approximately 20% more filter medium. They also have an additional lid at the bottom of the filter.
