The First Need XL is the only pump style filter we reviewed that is effective against viruses. This is remarkable because the only other systems that do treat viruses are chemical, like the Katadyn Micropur Purification or UV light treatments. Since this filter works for more diseases, it is preferable to use for international travel or for really gross water sources. If you want a reliable filter that offers the ultimate protection, this one does the job. With that said, this is also the heaviest and most expensive filter in this review. It is so large and clunky that it would be a terrible choice for hiking in the backcountry. This is also not the choice for someone on a budget since it is the most costly purification method we reviewed. A more economical choice would be Potable Aqua Purification Tablets, which still treats viruses, or the MSR Miniworks EX, which lasts a long time.
