Most viruses are very, very tiny and most are not filtered by this system. Have you considered adding chemicals for this?

Hi Prsmith, Thank your for your comments. Yes we are aware that this straw while highly effective for the common bacteria and heavy does not filter for viruses. That is why we developed 3 other straws that use MIR Hi-Poly Iodine Resin to effectively filter 99.999% of common viruses. While the other filter medium contained in the straw filters out 99.999% of bacteria and heavy metals. Please check out our 3 other water filter straws here on Amazon: H2OLIFEGUARD,H2O SURVIVAL Water Filter Travel Straw & H2O SURVIVAL Water Filter Travel Straw MAX. It should be noted though that pregnant woman and those allergic to Iodine should not use this straw.

Windows 8.1 includes very basic virus protection in the form of Windows Defender, it is not a comprehensive solution but it should suffice for most basic users.

Yes! The authorities say that the virus only lives on surfaces a few hours and is communicated only by bodily fluids so please enjoy these fabulous towels high quality and beautiful workmanship , very soft and launder very well and they are sized larger than most!

Hi I had to contact Customer Services, which, at best, is hit and miss and at worst is an appalling experience Beware of their tendancy to try and sell you "essential clearing of numerous viruses from your infected computer" I use Windows Defender, CCleaner and Malwarebytes, all free to download, I binned Mcafee Good luck

Berkey doesn't publish micron ratings as they're a little misleading. From their website, if a filter traps of 0.2 micron particles then it's acceptable - even if the other 10% lets in 1.0 micron particles - to call it a 0.2 micron filter. But if you read the test results on their website, their filters are capable of filtering 99.999% of viruses and 99.9999% of bacteria. That's better than almost any filter out there. In fact, you test the filter by adding a teaspoon of red food coloring to a gallon of water and running it through the filter. I can vouch for the fact that in mine, the water comes out crystal clear.

very little unusual taste on the treated water and i don't think there is enough contaminates for it to be filtered. if you see anything bulk in the water, then by all means go ahead and filter it.

I have never used the micro but I know the Hiker Pro is a great filter. I have used it along much of the southern section of the AT. I even used it last year along a section where norovirus was a real problem without getting sick. I have also used it on winter hikes and had no trouble with it freezing as long as I kept it warm in the foot of my sleeping bag at night. As long as you are not going somewhere with an abundance of very small viruses there is no need for additional treatment.

filters do not kill viruses. If you're concern about virsus you need to add a water purifier.

Not much to add to Greg's very complete answer... The main thing you need to know is: filter / treatment system (0.1 micron) = eliminates only bacteria, purifier (0.02 micron) = eliminates viruses as well as bacteria. Both are as good as it gets in their respective fields, so basically your intended application is what will determine your choice...

It filters any particles to 0.2microns 99.999% of all waterborne bacteria is filtered along with 99.99% of waterborne protozoan cysts.E-coli cholera salmonella cryptosporidium giardia. It was used in Haitia and being used by govt relief groups cant be used for saltwater or water treated with chemicals. doesnt remove viruses heavy metals radioactive material or anything smaller than 0.2 microns best for use in lakes or river. good for5 years unopened.

I'm using the free version of Avast. It is highly reviewed and so far is running seamlessly. Also I loaded Spybot, since Avast does not have a malware module.

Nope, Ive now had mine for quite a while and everything is working just fine. No filters needed.

I am sorry but I really don't know, I am not technically at all. I had a virus on my computer and this removed it very quick and easy. I did call customer service before ordering it to see if it will help with my virus and they were very helpful. I would suggest calling customer service before ordering it.

This does not stop virus or bacteria in any way, so you would still need to boil it if you are drinking unsafe water. You would need some kind of UV (ultraviolet) Light filter in order to kill live pathogens. This does stop heavy metals, prescriptions drugs and some other stuff though.

I know you asked this months ago but I think all the answers given were incorrect and it is an important question. The product description lists aesthetics, chemicals, dissolved solids and radiological contaminants not biological contaminants. If you look at the Seychelle website, they describe their filters. The advanced filter removes bacteria and viruses but this one is meant to be used with potable water. They now have a combination advanced/radiological that they call "extreme" which covers everything. I apologize to Seychelle if I am incorrect, but if you read the product description carefully they do not say that this filter removes biological contaminants. Seychelle has the only filter I"m aware of that covers radiological. I'm about to order this and will use it with water purification tablets if I'm drinking non potable water.

This filter is tiny. It definitely can't hold any bioballs. There is only a small sponge inside for mechanical and biological filtration.

NO. The wavelength is far from the range necessary to disinfect, and the output is weak; both factors (as well as time of exposure) are critical for disinfection.
