100 pints/day · 5,500 sq ft · Gravity drain · $1,878 (sale) at Sylvane as of Oct 2026

The AprilAire E100 (formerly model 1850) is rated at 100 pints per day at AHAM conditions and 85 pints per day at 73°F. AprilAire quotes coverage for whole houses up to 5,500 sq ft; Sylvane lists 5,200 sq ft ducted. It is ENERGY STAR Most Efficient 2025 with a published energy factor of 2.6 L/kWh at 80°F / 60% RH.

Airflow is the E100's strength: 280 CFM at zero static, 245 CFM at 0.2 in. and 210 CFM at 0.4 in., which holds up far better under duct pressure than the E080. It shares the E080's 14 x 15 x 26 in. cabinet at 64 lb, so it fits the same access openings while delivering 25% more rated capacity. Rated draw is 6.7 A and the spec sheet lists 55 dBA ducted.

The E100 uses a threaded drain elbow and gravity drain with no pump included, a washable MERV-8 filter, and R32 refrigerant. The spec sheet warranty is 5 years (a Sylvane image mentions a 6-year 'Total Peace of Mind' warranty; we use the spec sheet figure). Sylvane price at verification was $1,878.

Pros and cons

Pros

Same cabinet size as the E080 with 25% more capacity
ENERGY STAR Most Efficient 2025
Made in USA

Cons

Our take

The E100 is the AprilAire to buy when you plan to duct the dehumidifier to a large or divided crawl space, or condition the crawl space and part of the house from one unit. It is louder than the E080 and still lacks a pump, but 280 CFM under load is a real advantage.

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.
