Why it matters
Aspen's Silent+ Mini Aqua uses capacitance sensing to vary its speed with the condensate level instead of switching on and off, which keeps it as quiet as 16 dB(A). It fits inside trunking or a mini-split unit.
Aspen rates it for systems up to 136,000 BTU, it accepts 100-250 V, and it includes a safety switch, mounting feet and a discharge connector, with a three-year warranty per the listing.

Good fit if

Pros and cons
Pros
- Variable speed
- 16 dB(A)
- Safety switch included
Cons
- Expensive
- Mini-split use only
