The Abestorm Guardian SN55S is the gravity-drain version of Abestorm's smallest crawl space unit (the SNS65 adds a pump). Abestorm rates it at 55 pints per day at AHAM conditions and 120 pints per day at saturation, with coverage of 1,300 sq ft, and lists it as ENERGY STAR certified.

The manufacturer page lists a 19.2 x 12.2 x 13.3 in. cabinet at 41.7 lb, the lightest unit in this comparison, along with 50 dBA, 130 CFM, R32 refrigerant, a MERV-8 filter, a 6.5 ft drain hose, a COP of 2.4 L/kWh and an operating range of 33.8 to 104°F. Amps are not published. Published features include auto restart, auto defrost and auto humidity control.

Abestorm's product page states a 5-year limited warranty; the SNS90 user manual describes it as 1 year on parts and workmanship plus 5 years on the compressor, condenser and evaporator, so read the fine print. Price at verification was $454.06 on sale at abestorm.com (regular $648.66).

Our take

At its sale price the SN55S is the cheapest ENERGY STAR crawl space dehumidifier in this group and the easiest to carry in. It is limited to small crawl spaces (1,300 sq ft), needs a gravity drain, and the warranty is 5 years only on major components. A fair budget pick when the space is small and sealed.

Not sure this is the right size? Run your square footage and moisture level through the sizing calculator, or compare every unit we cover on the best crawl space dehumidifiers list.
