Mini-split accessories
The indoor head sheds water as it dehumidifies, and it needs somewhere to go. If your head sits above the drain exit, gravity handles it and you need nothing. If it sits below, you need a condensate pump to lift the water out. The features that matter: enough lift height for your run, a built-in safety float switch so it shuts the system off before it can overflow, and quiet operation if it's near living space.

The popular choice for mini splits - a low-profile pump that tucks behind or beside the indoor head with a small reservoir. Aspen's Silent+ Mini Aqua is the premium pick here because it is quiet, compact, and rated across 100-250V power.

A larger-reservoir pump for utility spaces or higher-volume runs, with more capacity and lift for when the head sits well below the drain. Little Giant's VCMA-20ULS is the long-standing installer-standard tank pump.

If your indoor head sits above the drain exit, you don't need a pump at all - a sloped gravity drain line is simpler, silent, and has no failure points. The honest first choice when your layout allows it.
