University of Toledo Professor and Chair of Chemical Engineering and Water Purification Expert G. Glenn Lipscomb confirms in an email to me sent today that good multi-stage Reverse Osmosis (RO) filter systems costing around $200 to install (often even less) and $60 per year for replacement filters are the method of choice to reliably clear Cyanobacteria and the microcystin toxin from your drinking water - and that the expensive NSF certified filters are NOT necessary.
There is no excuse to resort to bottled water and contribute to the dangerous plastic pollution of our planet. Below is Prof. Lipscomb's email that I share with his permission.
Tom,
I am sorry to hear you are experiencing water quality problems. I know how frustrating and infuriating it can be.
I cannot guarantee the quality and efficacy of all RO systems that are available for point-of-use treatment at home. However, the ones we tested provided excellent removal of microcystin – to non-detectable levels.
We still are preparing the papers from the work. The thesis of the graduate student who performed the work, Neelam Jagani, is available here:

Hope things improve soon,
Glenn

Tom Wassmer: I am more than happy to help Adrian residents and businesses with locating the right RO system free of charge.
Update, Good system at just $176:
