No, leave the straw in. They ain't effective against viruses but they are useful for filtering particulates out.



That's what I wasn't sure about. I believe there's a lot of discussion regarding those straws?



Filter straws seem typically to have a filter of 2-3 microns. Viruses are 0.5 to 1 micron. So they are ineffective against viruses. Therefore chlorification is required first.

MP-1 it then drink through the filter. MP-1's are very effective but for emergency use two layers of purification is no bad thing.
