Santa Fe dehumidifiers were developed by Therma-Stor, which holds the Santa-Fe trademarks. They are contractor favorites for encapsulated crawl spaces and basements because they are built for continuous duty in cool spaces and can be ducted. Most are rated at the AHAM condition of 80F and 60% RH, so their pint numbers are not directly comparable with a portable's DOE rating.

| Compact70 (formerly Compact2) | 70 (AHAM) | 150 CFM | Crawl spaces | Low profile; runs 49F to 95F (data sheet) |
| Ultra70 | 70 (AHAM); 52.45 at 73F | Not listed here | Whole home, ventilating | 5.5 pints/kWh at 80F |
| Advance90 | 90 (AHAM) | Not listed here | Crawl spaces, basements | 11.25 gal/day (catalog) |

Santa Fe vs AlorAir vs Aprilaire
| Santa Fe Compact70 | AlorAir Sentinel HDi65S | Aprilaire E070 | |
|---|---|---|---|
| Rated pints/day | 70 (AHAM) | 55 (AHAM), 120 saturation | 70 (80F, 60% RH) |
| Airflow | 150 CFM | 130 CFM | 200 CFM |
| Pump | No (add-on) | Yes | Wi-Fi version bundled with pump |
| Low temperature | 49F (data sheet) | 33.8F (maker) | Not stated here |
| Wi-Fi | No | Yes | E070W |
AlorAir is usually the lowest price of the three and runs closest to freezing. Santa Fe and Aprilaire are the traditional contractor brands. On ENERGY STAR's whole-home records, Santa Fe's newest Ultra V-series post the highest efficiency of any brand we checked. See our Aprilaire review and crawl space guide.
Verdict
For an encapsulated crawl space, the Santa Fe Compact70 remains the safe, standard choice. For a whole home that also needs fresh air, the Ultra70 is unusual and useful. For big basements, the Advance Dry110 or Classic have the capacity. If your crawl space gets close to freezing, look at AlorAir instead, because the Compact70's data sheet lists 49F as its minimum.
