AlorAir Sentinel HD35P Crawl Space Dehumidifier vs AlorAir 180 Pint Crawlspace Dehumidifier

Both are AlorAir compressor dehumidifiers with built-in pumps, so the choice comes down to size and capacity. The 70 PPD unit is compact, lighter at about 38 lb, and easier to move into tight crawl spaces; the 180 PPD unit moves far more air and moisture for larger or wetter spaces. Owners of the smaller unit report reliable constant-duty running and low noise, with one pump failure after a few years; the larger unit draws praise for easy setup and strong pump drainage, though its review base is small.

• Choose the AlorAir 70 PPD if your space is around 1,000 sq ft or less and you want a compact, lighter unit that fits through a tight crawl space access.
• Choose the AlorAir 180 PPD if you are drying a large basement, encapsulated crawl space or commercial area up to about 2,300 sq ft and need maximum moisture removal.
