Breaking Micropur Tablets in Half?

I've done it a couple of times but didn't like the results. The remaining half tablet will decompose to powder quickly after it is exposed to water vapor in the air and, I presume, looses its powers as well. To me, the tablets are not expensive enough that it is worth the trouble cutting them in half.

I too have found powder in some of the packets I opened. I assumed that the packet seal had broken and that the tablet inside had absorbed water and lost its effectiveness. I just sprinkled the powder on the trail and opened another. One lot of Micropur that I bought had over 10% of the tablets as powder. Kind of annoying it was.

This isn't directly related but when I was in Peru last fall I picked up some MicroPur tablets and they were much smaller and very hard in packaging more similar for non-prescription drugs. Impossible to break in half but also indestructible. I find it interesting that they have two very different products for the same thing and I'm wondering if both are similarly effective or not.

But I have had a problem with the micropur tablets becoming powder since I usually just carry them as backup (and they make many trips) in case one of my Aquamira bottles leaks (which happens).

Hi Kirk

I wonder … were they really 'MicroPur' or a locally-made clone? Sadly, this happens a LOT. But I do not know in this case.

Cheers

Haha – I hadn't even considered that since there really isn't much in the way of trademark/copyright protection. Pretty much the only thing I care about is if they work. If I get motivated I might write and ask Katadyn/Micropur if they have a separate South American product.
