Name: AlorAir Sentinel HDi90
Brand: AlorAir
Price: 1147.00 USD

90 pints/day · 2,600 sq ft · Built-in pump · $1,147 at Sylvane as of Oct 2026

The AlorAir Sentinel HDi90 is AlorAir's mid-size crawl space unit with a built-in condensate pump. It is rated at 90 pints per day at AHAM conditions and 198 pints per day at saturation, with coverage of 2,600 sq ft. The pump lifts up to 14.7 ft. A drain-hose version without the pump is sold as the HD90 for $100 less, and a ductable HDi90 variant is available at the same price.

The 2025 spec sheet lists a 23.2 x 15.2 x 17.7 in. cabinet at 70.5 lb, under 58 dBA, 5.56 A at 115 V, 210 CFM airflow, R32 refrigerant and a COP of 2.69 L/kWh. Sylvane's listing title calls it ENERGY STAR, but the model is not in ENERGY STAR's certified list, so we show it as not certified. A MERV-8 filter is listed as optional rather than standard, which is a step below the Santa Fe and AprilAire units.

AlorAir's warranty is 6 years limited with the first 2 years full coverage, and the Amazon listing also states a 6-year limited warranty. Sylvane price at verification was $1,147.

Our take

The HDi90 is the best-value pump unit here for a mid-size crawl space: 90 pints AHAM, a 14.7 ft pump and a 6-year warranty for about half the price of the Santa Fe Oasis105. The published 58 dBA and optional filter are the compromises. Note that the Abestorm Guardian SNS90 publishes identical dimensions, weight, CFM and COP at a lower sale price but with a weaker filter and warranty terms.
