Abestorm is a California-based direct-to-consumer seller of crawl space (Guardian) and commercial or restoration (Hurricane) dehumidifiers. The company says it has been developing drying equipment for over 20 years but publishes no founding year, and no parent company is disclosed. Guardian units are sold through abestorm.com and Amazon, usually at a sale price well below the listed regular price.

We cover three Guardian models: the SN55S (55 pints AHAM, gravity drain), the SNS65 (the same capacity with a built-in pump) and the SNS90 (90 pints AHAM with a built-in pump; the SN90 is the gravity-drain version). The Hurricane line is not a crawl space product and is not covered here.

What sets Abestorm apart

Price. At verification the SN55S was $454.06 on sale (regular $648.66) and the SNS90 $745.62 on sale (regular $1,147.11) on abestorm.com. Those sale prices make the SN55S the cheapest ENERGY STAR-listed unit we cover and the SNS90 the cheapest 90-pint pump unit. Both use R32 refrigerant, and the SN55S is the lightest unit in our comparison at 41.7 lb with a published 50 dBA rating.

The SNS90's published specs (23.2 x 15.2 x 17.7 in., 70.5 lb, 58 dBA, 210 CFM, COP 2.69 L/kWh) are identical to the AlorAir Sentinel HDi90, and the two companies' regular prices are within a dollar of each other ($1,147.11 vs $1,147). We report the figures as published and do not speculate about shared manufacturing.

Filtration and warranty are where Abestorm gives ground. The SN55S lists a MERV-8 filter but the SNS90 spec table lists MERV-1, which is a coarse screen. Product pages state a 5-year limited warranty, while the SNS90 user manual specifies 1 year on parts and workmanship and 5 years on the compressor, condenser and evaporator. Amps are not published for either unit.

SN55S or SNS90?

The SN55S is a budget pick for a small sealed crawl space (1,300 sq ft claim) with a gravity drain; it includes a 6.5 ft drain hose and moves 130 CFM. The SNS90 (2,600 sq ft claim) is the one to buy when you need capacity and a pump on a budget; its pump lifts 14.7 ft and ships with a 19.6 ft drain line and an 18 ft power cord.

If a better filter or a longer full-coverage warranty matters more than the sale price, the AlorAir HDi90 publishes the same hardware specs with a 6-year limited warranty, and the Santa Fe Compact70 offers MERV-13 filtration in a smaller cabinet.

Warranty

Product pages state a 5-year limited warranty; the SNS90 user manual specifies 1 year on workmanship/materials and 5 years on compressor, condenser and evaporator.
