Pond filters do, indeed, filter out some physical debris
as water passes through them. However, contrary to popular thought,
this is not their main purpose. They actually do much more to keep
the water of your pond healthy (Note: do not equate "healthy"
with "clear." You can have clear water that is actually
quite unhealthy for fish - it can be full of invisible toxins).
The media within each filter has a large surface area
for beneficial bacteria to live. These bacteria break down invisible
toxins caused by the breakdown of organic material (like excess food,
fish waste, and leaves). They change ammonia into nitrite. Another
bacteria breaks nitrite into nitrate. Plants then absorb the nitrate.
Realize that when you first start using a biological
pond filter it may take a few months for the beneficial bacteria to
build up enough in the filter media. If you do not have fish, you
may not need to use a pond filter.
