Seems a little spend and maybe overkill for my usage. But thanks for the link

I find it really interesting that it will remove chemicals too. Here in the midwest, I often wonder about ag runoff and if I'm drinking roundup or some other herbicide.

Same here. If will remove chemicals, I wonder if it would be useful for going down the Minnesota river.

Pick the amount of protection you need S1/2/3, great idea. Wonder if or how long before Sawyer gets it certified by the EPA?

Sawyer has a good reputation so it may be worth giving it a try. I couldn't find where it listed an actual water capacity. Now if they would only convert that technology over to a gravity filter...

For a comparison First Need Purifier has 23000 ounce life, and has EPA certification.
Having converted First Need, Sawyer Minis and MSR Trailshot to gravity use, I expect it would not be difficult to do the same with a S type filter/purifier.

Just how many filters does a guy really need to try??

Oh. I've owned five... Never mind...

The bottle is 20 oz., so limited in that regard. Since the bottle holds the adsorption foam, it seems a gravity system would be limited to that. It would probably be best for solo use.

Yes, not really sure I need a purifier, but if I did . . .

Yeah, it says it was independently tested to EPA standards, but that's not exactly the same as EPA certification.

Ain't that the truth! Always something new and improved, fresh on the market.

Yes sir, the certification sounds important but passing recorded standard is really the goal. As for rigging it for gravity feed I could see a tubing bulkhead on off valve in the bottom of the squeeze bottle. I bet gravity flow would work but it would be a sizable rig and with the amounts desired from a group gravity setup stressing the total filtered capacity. For large amounts of filtered water it is very had to beat a Sawyer Squeeze .1 micron or .02 micron (which can remove most viruses), inline filter setup.

In response to the question of whether they were EPA certified, I received the following response:

Thank you for reaching out to us. All of our Select filters are EPA certified. The testing documents can be found on our website here:

This thread prompted my curiosity. Instead of the new Sawyer purifier, I purchased a First Need XLE Elite Water Purifier for $80 at Campmor using coupon code SAVE20 + free shipping.
kanoes gave it high praises and that's good enough for me and my needs.
