Except that the Aqua Mira Frontier Pro filter is 3.0 microns. I had to do a lot of research to find that out because (3 years ago) Aqua Mira did not disclose the filter diameter. (I just checked their web page and they still don't!) The CDC recommends a 1.0 micron filter for protozoa (giardia and crypto).
