Looks like this may be a perfect filter to use with Crestworths and Mathmos globes. It seems that the MSR mini works filter removes up to 0.3 microns and this Pure easy removes up to 0.1 micron. Perhaps the MSR removes way to much out of the liquid and that is why it can only be used once to filter the vase out.
This Pure easy filter did a great job on your vase. And they cost half the price if not a little less to buy.
