Rated 2 out of 5 by Len5742 Not recommended for backpacking
When backpacking I don't cook so, in theory, this bottle seems perfect for meeting my needs. Unfortunately, not the case in actual practice. And practice I have, as I carried this thing for thru-hike of the Arizona Trail, as well as through New Mexico on the Continental Divide Trail. Two months+ of trail time.
Problems seem to stem from the pressure equalization vent thingie in the top of the bottle. I put a Camelbak electrolyte tab in my water. The gas generated by dissolving of the tab seems to force water out the vent and/or the drink tube. If I flip the top open, all of a sudden there's a big blurp of water dumped out on me. OK, so let's say I leave the top off for a few minutes to let the gas out. Not at all convenient, but might be worth the effort if that was the only problem. It's not. As the bottle rides in the pack side pocket, walking causes the water to eventually slosh out. After a few minutes, I feel something wet running down my leg. Not enjoyable. Water is coming out, eventually through the pressure equalizer, is my guess. Once the bottle contents are significantly drawn down, this stops, but that's no solution. Lastly, want to keep your bottle in your sleeping bag overnight, for warmer water that's drinkable in the AM? Be prepared for water to leak out, presumably through the vent.

Rated 5 out of 5 by Rico Great little filter.
I too brought this with me to Belize. Filtered everything. No illness. However, the lady below commented on her family having a stomach virus and not her. This bottle DOES NOT FILTER VIRUSES!!! Just to be clear. But great for what it's for.

Rated 5 out of 5 by gpa317 Great work!!!
Went to Belize with my family while we where there went to a little restaurant. Anything I drank I would pour into my Sawyer Personal Water Bottle first. My family looked at me like I was a nut, that night back on the cruise ship all 7 of them had a stomach virus. Not to be mean but sitting at that big dinner table alone made me laugh. (Thank you for the time alone haha) and yes they all survived but they all have plans on getting there own bottles before the next trip.

Rated 4 out of 5 by JohnAbela Great way to get a water bottle & filter all-in-1
The Sawyer Personal Water Bottle with Filter is a pretty sweet way to be able to carry a water filter and a water bottle for those that do not need to deal with carrying water in external water bags. And even if you do need to carry a few extra liters of water with you for the long sections of a trail, you can always carry dirty water in the Sawyer water bags and then pour the dirty water into the bottle and you are still good-to-go!
The Sawyer Personal Water Bottle with Filter uses the Sawyer Mini inside of it, so its got one of the best non-chemical water filters for hikers that is on the market - an Absolute One Micron filter.
There are a number of different companies making these 'filter in a bottle' systems and the Sawyer one is one of two that I grab most often.
Here are four changes I would like to see Sawyer make with this product:
First is that the plastic bottle flairs out on the bottom - this is a serious pain because it makes it so wide that it does not fit into any pocket in any of my hiking setups, except the side pocket of one specific backpack. If Sawyer had a taller bottle that was narrow for the full length that would be awesome - this is the #1 reason why I do not typically use the Sawyer Personal Water Bottle with Filter and use another brand instead.
Second is that the plastic bottle is kind of harder than it needs to be. All of the other 'filter in bottles' that I own have much software plastic, making it a lot easier to squeeze them. This is kinda important if you plan to use this to filter your water into your food bag (cold cook hiking).
Third, and in-line with what I just ended the last issue about, is because it is so hard to squeeze the bottle, and because of the fact that the Mini filter only has a small hole on the bottom of it, once the water gets below the point where if you angle the bottle to squeeze the water out, it just sucks air. A method needs to be figured out so that it can continue to suck water until the bottle is almost empty. I did this via hacking up some tubing I had sitting around, but it is still not perfect.
Fourth would be a larger hole at the top - Sawyer has it just big enough for a biner, but not big enough to put your finger into, which my other ones have and I have found to be rather nice when I am carrying a bunch of water back to a campsite.
Anyway, all four of these issues are rather minor, and mostly pet-peeves on my end.
When it comes down to it, the Sawyer Personal Water Bottle with Filter is one very sweet method of carrying dirty water that can be made safe to drink very easily - perhaps the easiest method that there is.
