| Our take | The same Cube design at 35.82 certified pints and the same 2.01 efficiency as the 50. For a basement we'd buy the 50; the 35 suits a smaller, less soggy space above 41°F. | 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. ENERGY STAR also lists MAD35W1QWT-A at the same 35.82 pints; we couldn't confirm it's a Cube, so check the model number. | 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. |
