under sink would be too inconvenient
and all the RO membrane cartridges, or millipore filter cartridges are contaminated with PFAS, anyhow. it's literally everywhere. We have to run ours for 30 minutes before taking the ultra-pure water at the lab to drop the levels down to 'baseline'. Otherwise, the built up levels blow out the instruments.
- tophi 4y ago30 minutes for every new filter? Or every time?
- kurupt213 4y agoEvery 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
- ars 4y agoWouldn't a carbon filter work better then? If I understand them right it will keep the pfas stuck inside itself and not let it diffuse.
- kurupt213 4y agoThe filters are carbon. Every filter has breakthrough. And the filter components themselves are contaminated prior to construction. This stuff is literally everywhere
