First Need Purifier Reviews:


I've taken this out on long trips and it's such a great thing to have. It does weigh a pound so if you're obsessively shaving packweight it might be a tough call but in my opinion it's easily worth it. Your water will always taste clear and fresh, and it removes all the bad microscopic stuff other filters won't. It's easy to pump, and the flow rate is pleasantly quick. I'm not sure just how compatible it is with different brands of bottles, but a standard trusty 32oz Nalgene screws directly into it. There is also a smaller inner 53mm thread to screw on smaller bottles, and a main "output spout". You can also filter water directly into your CamelBak (or Platypus or what-have-you) by popping off the bite valve of your reservoir's tube and fixing the tube directly over the output spout. There are adapters available from the company's website if you're intent on using some nonstandard sized bottle. Basically, if want the cleanest water possible while backpacking and don't want to deal with chemicals in your water, the First Need is your best option.

The size of this product isn't too bad. If you made 2 clenched fists and put them side by side, this purifier is slightly larger than that. I can fit it into my 3 day pack without removing too many "luxury" items, but seems like it would be better utilized on longer trips or with a group of people.
This product seems solid enough. I am not concerned with placement in my pack, no need for it to be on top of everything, or padded by clothing or anything like that. It seems like it will take a bit of a beating, and remain functional, thought, I cannot say for certain... I'll let you know when I break it!
I would say that for the additional cost over a filter, the capabilities of this purifier to eliminate bacteria and virus' make this a great purchase. It will save you the time and trouble of boiling, or potentially running out of purification tablets when you need them. It is easy to use, and easy to clean out.

About the size of a coconut and a little larger than some of the other models, but worth it, as it pumps easier and filters better. Was able to get flow from about a 2-3" pool of water. The different types of threads for different bottles is a plus, but water can still flow into any bottle simply by holding it underneath the spout. Requires about a dozen pumps to drain the remaining water out when you are finished so that it doesn't leak in your pack, but this is typical. Has survived a couple of drops onto the ground with no damage so far.

This is probably one of the best water purifiers to date. It purifies well and the resulting water tastes good. Only problem is the size. If you are using this for a group of people, this purifier is worth it. Each filter pumps a large amount of water, it pumps fast and you can split of the weight of other items in your pack in order to make room for this. But for 1 or 2 people, a smaller purifier is preferable.

I am a really protective father. From my research and my experience with this filter, I allow my two young sons,3 and 6, to drink water from this. I hope that my research and experience has been adequate but so far everything has been great. ken
