Neat thing to have

I finally got a chance to use the water filter. Remember to read the directions and flush a couple ounces out before you drink or you'll get a mouth full of coal saturated water. Easy to do though. Overall this product is very useful and well made. It is very light, which is a plus for hiking. Dip and drink. The only thing that seems a little hokey is the bite cap. I don't know how long the cap will last because when I bite it to twist it open there are indentations where my teeth made contact with the cap. We’ll see. I used it 2 days ago and I'm not sick yet, so I guess it works.

Fills the bill

Bought one for an ultra light pack in bow hunt for Colorado elk. At 57, every ounce counts on my back and legs! I used this bottle every day with streams and springs found as we hunted big timber at 10,000 feet. Plenty of animals around, including cattle at lower elevations, so water safety was vital. This bottle allowed me to hunt with only one water bottle and no separate purifier or nasty iodine tablets. My hunting partner even borrowed it to filter extra drinking water. We stayed healthy and happy. Easy to clean and dry for storage after the trip. Very pleased with the product, will also carry it on day hikes around home.

Shopping for my nephew's first water filter online for Christmas. Found the Katadyn which looked like the right one at another famous backcountry gear behemoth that everybody is a member of. Then, found water filter AND replacement cartridge at Backcountry.com for the same price behemoth had for just the filter.

Katadyn Micro Filter Bottles

My son and I have used these bottles on several trips into the remote Northern Ontario bush. Instant safe water supply when fishing the remote lakes and streams..

Bottle is quite easy to use and inexpensive but the capacity is quite modest and you need finger power to squeeze it hard enough.
