Unlike a regular filter, where the water is pumped from the stream into a container, with the Aquamira Frontier Pro Water Filter, the container is filled with water from the stream or lake, and then filtered as you drink it. The filter uses a small "button" looking filter that does not remove viruses and may not be effective on removing all types of bacteria. If extra treatment is needed use some Aquamira Water Purifier Tablets .
The filter was easy to use. You just get close to the water, insert the straw and suck the water up. The nipple that fits into the mouth is protected with a plastic cover. One unit is supposed to filter up to 20 gallons of water and be able to remove 99.9% of Cryptosporidium and Giardia.
