Most filter everything other than viruses. From what I've been told, viruses are more of a concern South of the border, in jungle areas. The owner manual that comes with your filter should tell you what it covers.

Different filters filter different things. You should read the package it comes in to see what the filter takes out.

Any filter system will have a lower limit on the size of particles that it can filter, so the added step of boiling will always be advisable to make sure that you get viruses, smaller bacteria and cysts/spores that your filter may not handle. A VERY small quantity of bleach (like 1 small drop per gallon) or exposure to UV light can also help control some of those water-borne hazards, but boiling is still advisable.

You also have to weigh your immediate need for water - if you will die of thirst before you can get the chance to boil water, go with what your filter will give you and take your chances.

As long as you don't venture to third world countries, a quality filter will take care of any biological nasties in the water. They will not, however, take care of industrial pollutants, nor most viruses. The good news is that these things rarely occur in the places where sportsmen spend their time. Here is a FAQ that might help:

You can trust the bottle when you need to but when I have the opportunity I boil the water just in case.

To play it safe when you don't have the opportunity to boil, carry a bottle of iodine tablets which purify the water. It adds a different taste to it(which I wouldn't classify as good or bad) but the water is safe.

In this day there is no such as a clean mountain stream. Free ranging cattle on summer range, beavers in their ponds and lodges, etc. Wild water needs to be purified. If you think you are dehydrated now wait until the diahrea does a number on you. Either boil it, treat it for the full three hours to kill the hard shell cysts, or filter it. There are micro filters and there are purifiers, A purifier with a filter of .004 microns will filter out everything viruses and all.

It depends on the filter type. You should read the instructions and if it doesn't say anything about that then boil it to be safe

another purification process if you have none of the above is, believe it or not, whisky. It can make water completely safe after a given amount of time of course. See the survival issue of the backpacker for more details it's awesome.
