Review on 💧 Enhance Water Quality with Purification Elements BB9 2 Replacement Filter by Charles Butler

Is there any further technical information on this? I'm not expecting Berke's level of quality, but are they good enough? How many microns of filtering etc? Depending on how they will be used I would like to know the specs to ensure the filter grade is good enough for most water conditions around the world. If I use rainwater or stream water will they get the job done? You don't need amazing, you just need good enough. Without basic information, I really can't make a purchase recommendation. I will check again if this information changes.
