Every time. They concentrate the pfas in the water, which bleeds through the cartridge as it sits there between uses, meaning all the diffusion breakthrough has to be flushed every time.
These filters only slow down the contamination relative to water flow rate. Think Of them as big chromatography columns or frontal analysis columns
The filters are carbon. Every filter has breakthrough. And the filter components themselves are contaminated prior to construction. This stuff is literally everywhere
