| Our take | A single-room Cube certified at 20.16 pints, lighter at 33.07 lb. It uses about 18% more electricity per pint than the 35 and 50, so two of these are a worse way to dry a basement than one Cube 50. | The crawl space unit for spaces that run cold: it keeps working down to 33.8°F and costs a fraction of a Santa Fe or AprilAire. Size it by 36.33 pints, not the 120 on the box, and buy from an authorized seller so the warranty holds. |

| Watch out for | Check the built-in humidity reading against a separate hygrometer in week one; a stuck-near-30% or ~20-points-low reading on a new unit is a known return-window fault. The original Cube generation (MAD20C1ZWS and siblings) isn't in the current ENERGY STAR data; confirm the listing says MAD20S1QWT. | Three units share the HD55 name: the original HD55 (R410A), the HD55S (R32, ENERGY STAR, gravity drain) and the HD55P (built-in pump). AlorAir's own Dec 2025 sheet prints 34.53 pints labeled 60°F/60% RH; the DOE test is 65°F, so use ENERGY STAR's 36.33. The ENERGY STAR listing names the HD55S and HDi65S, not the Wi-Fi HD55S, and an older Wi-Fi spec sheet still says R410A. 6-year limited for orders from Apr 14, 2026: 2 years full, then refrigeration parts only. A unit sent in for inspection ships at your cost after 6 months, there's no in-home service, and coverage requires purchase from AlorAir or an authorized dealer. |
