This mainly filters bacteria and Protozoa.
Can anyone recommend a portable filter the filters out nitrates? City water system has once again been overwhelmed by farm runoff. It"s like an annual event now. Of course they say it years for healthy adults but I prefer safe water.
If it’s 99% effective, it seems like it’s letting 1% through. So that’s like 1 out of 100 of these bacteria and protozoans make it through?
