We took our Seychelle Advanced filter canteen out to the reservoir to try it out and see how well it worked. The 2 micron filter will remove just about any nasty bug and filter up to 100 gallons per filter in ideal clean conditions. Removes cysts, giardia and cryptosporidium and most viruses. The Seychelle advanced canteen uses a iodine resin filter, there are also several different types of filters that are offered so be sure what yours contains, using the wrong filter could make you severely sick. Further in the article I will post the filter types and what they remove. Very good product for the price $31.95 compared to other high dollar filter bottles. I did notice a little bit of an iodine aftertaste because of the filter which Im sure will dissipate after some use, The main reason I chose this canteen is that it is similar in size to the military style one quart canteen and can be carried in the molle canteen holder w/ canteen cup and fits seamlessly with tactical gear or attached to bug out bag.
A great Item I think for any survival or preparedness plan and wanted to share this with my page viewers.
