I don't think you filter viruses, they are typically 100 times smaller than bacteria, (E. Coli, crypto, giardia, etc.).
In order to rid the water of viruses, I have always read and understood that the water must be treated with something, boiling, iodine, bleach, etc.
The Sawyer is a great system, doesn't work super well in silty water, but if it's clean or settled, it's hard to pass up. The dromedary bags are great and putting the mini inline works like gravity should.
