| 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 E100 with Wi-Fi and app control; the Amazon bundle adds a condensate pump and hanging kit. The version we'd buy for a crawl space or attic you rarely visit. |

| 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. The E100W isn't named in ENERGY STAR's E100 record, though its shop page claims Most Efficient. The 6-year warranty is the shop page's wording; the Amazon bundle's warranty field says 5 years and we found no printed E100W warranty. Keep a copy of the shop page with your receipt. The Amazon bundle title claims 4,400 sq ft; AprilAire's shop page says 5,500. |
