Any recommendations for a non-invasive RO solution for an apartment unit like https://www.amazon.com/SimPure-Y7P-BW-Countertop-Filtration-Purification/dp/B0BHZSJHWG or https://www.amazon.com/APEC-Water-Systems-Portable-Countertop/dp/B0833H346X? Something you can uninstall when you move out. I currently have Berkey black element filters and supposedly can clear pfas/pfos?
