Daniel wrote a review of First Need XL Water Purifier on February 27, 2003
After doing much research for a purifier suitable for our cycling world tour (see http://wainwrightschool.com/worldtour for more info) we decided on the First Need since it is the only water treatment that can filter out viruses without chemicals. A ceramic filter would be longer lasting. Alas, there are trade-offs with everything. You will be able to find out if we get sick or the purifier breaks on our world tour pages above.
