The short version
The filter is immediate; the tablets are lighter and slower. A squeeze filter gives you drinkable water in the time it takes to fill a flask, which matters when you are running rather than camping. Tablets weigh almost nothing and need a wait, commonly around thirty minutes, and longer in cold or cloudy water. Neither removes chemical pollution. Many runners carry the filter and keep a strip of tablets as the backup for when it clogs or freezes.
Common questions
Is backcountry water safe untreated?
Do not assume so. Giardia and other pathogens are present in plenty of clear-looking mountain water, and grazing and human traffic upstream are invisible from where you are standing. Treat what you collect.
What about chemical contamination?
Neither of these deals with agricultural runoff, mine drainage or industrial pollution. If you are running below farmland or old mine workings, that is a route planning question rather than an equipment one, and local advice is worth seeking.
Do I need this if my race has aid stations?
Usually not, and mountain races with long gaps between aid sometimes require or recommend a means of treating water. Read the race information, and carry something if a section is more than a couple of hours in heat.

Choose the Sawyer Mini Water Filtration System if…
You want water you can drink at the stream. A squeeze filter threads onto a soft flask, works in seconds, and does not change the taste, which matters when you are already struggling to drink. It clogs over time and needs backflushing, and it is destroyed by freezing, so it goes inside a jacket on cold nights rather than in an outside pocket.

Choose the Aquatabs Purification Tablets, 100 pack if…
You want an emergency option that weighs nothing and cannot break. A strip of tablets lives in a vest pocket indefinitely and covers the day the filter clogs or the route is drier than expected. The wait is the cost, and it is a real one when you arrive at a stream already empty.
