The Mini's weight with a flow rate you will not resent at a resupply.
The Micro uses the same 0.1-micron hollow-fibre membrane as the rest of the range, which covers bacteria and protozoa and therefore every realistic risk from a temperate stream. It threads onto the same standard 28mm bottle necks, so it works with disposable bottles, the supplied pouch, or inline on a bladder. The rated 100,000-gallon life is well past anything a touring rider will reach.

The reason to pick it over the Mini is throughput. Owner reports consistently describe the Micro as meaningfully faster to squeeze, and that gap widens once you are filling four litres at a resupply rather than topping up one bottle. The reason to pick it over the full Squeeze is that it weighs 20g less and takes up less room in a frame bag.
The same two caveats apply as to every Sawyer. The membrane cracks if it freezes with water inside, silently, so it has to sleep in your bag below zero. And it does nothing about viruses or chemical contamination, which makes it the wrong filter for regions where those are the actual risk.
The Verdict
The Sawyer worth buying if you are choosing between the three. Same weight as the Mini, most of the Squeeze's throughput, and the same buy-once filter life.

The Good
- + Mini weight with substantially better flow
- + Standard 28mm thread fits bottles, pouches and inline use
- + 100,000-gallon rated life outlasts any touring use
- + Cheaper than the full-size Squeeze
The Bad
