| Our score | SCORE5.7 / 10 | SCORE7.2 / 10 |
| Our take | A compact ducted unit for a small or very tight house: 52.45 pints/day at 73°F per Santa Fe, MERV-13 and an outdoor-air port in a 12 in square cabinet. For most whole-house jobs the AprilAire E080 or E100 removes more water for similar money. | The whole-house dehumidifier we'd duct into a humid forced-air house or put in a large sealed crawl space above the mid-50s: 85 pints/day at 73°F, ENERGY STAR Most Efficient. Standalone, it mostly dries its own room. |

| Watch out for | Its 52.45-pint figure is Santa Fe's own at the 73°F whole-home test; the Ultra70 isn't on ENERGY STAR's list, and the figure isn't comparable with a portable's 65°F rating. Santa Fe markets 6 years; the manual's terms are 5 years on the product and 6 on components, with labor, shipping and removal excluded. Owners report evaporator refrigerant leaks and units failing within the first year; most reports predate the current R454B part 4044100. Previously sold as the Ultra-Aire 70H (earlier part 4033730); the Compact70 is a different crawl space unit. Running without the recommended filter voids the warranty. | ENERGY STAR's 85 pints/day is at the 73°F whole-home test; don't line it up against a portable's 65°F rating. Dehumidifies only above 50°F inlet air and a 40°F dew point; a crawl space that drops below that in winter leaves it idle. The 5,500 sq ft coverage claim is the maker's; size by moisture load, and duct it if you want it to dry more than its own room. Amazon's "E100 Pro" and "E100P" are listing and bundle names, not AprilAire models. |
