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 and a safety switch. Aspen (Mini Aqua/Mini Orange) and Rectorseal make well-regarded ones.

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 series is the long-standing standard.

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.
