90 pints/day · 2,600 sq ft · Built-in pump · $746 (sale) at Abestorm as of Oct 2026

The Abestorm Guardian SNS90 is a 90 pint per day (AHAM) crawl space dehumidifier with a built-in condensate pump, rated at 198 pints per day at saturation with coverage of 2,600 sq ft. The pump lifts 14.7 ft and ships with a 19.6 ft drain line; the SN90 is the same unit without the pump for $733.

Its published specs (23.2 x 15.2 x 17.7 in., 70.5 lb, 58 dBA, 210 CFM, COP 2.69 L/kWh, R32) are identical to the AlorAir Sentinel HDi90. Where it differs is the filter, listed as MERV-1 in the spec table, and the warranty: the product page says 5-year limited while the user manual specifies 1 year on workmanship and 5 years on the compressor, condenser and evaporator. It has an 18 ft power cord and a metal casing. Amps are not published.

The SNS90 is not in ENERGY STAR's certified dehumidifier list. Price at verification was $745.62 on sale at abestorm.com (regular $1,147.11).

Our take

The SNS90 is the lowest-priced 90-pint pump unit in this comparison and a strong value if the sale price holds. Budget for a better filter (MERV-1 is a coarse screen) and understand that full-coverage warranty is 1 year, not 5. If those matter, the AlorAir HDi90 costs more but publishes the same hardware specs with a 6-year warranty.
