Living area
What you see in the basement
It's the right size.
For a 2,200 to 2,800 sq ft home with condensation on the walls or windows, you need to remove about 102 pints a day (spec sheet conditions). It removes 75: enough for the house, with some reserve for humid weeks in July.
Calculation: pints a day needed for the living area and the basement's condition, at the spec sheet's test conditions. Our estimator measures the humidity on site before ordering.
What it does, in numbers
$121
Electricity per year
8 h of running a day, May to October
Same calculation for every line: wattage × running hours × 184 days (May to October) × 11.142 ¢/kWh. The unit stops on its own once the target humidity is reached, so its running hours depend on your basement.
Capacities, efficiency and electrical data: manufacturer's spec sheet. Running wattage calculated: litres per day ÷ litres per kWh ÷ 24 h. Cost: Hydro-Québec Rate D, second tier (11.142 ¢/kWh), in effect since April 1, 2026.
What you should know about this one
Published, verifiable facts, not brochure claims.
Wi-FiAdjustable from anywhere
Touch screen on the unit plus a Wi-Fi app: set the humidity from anywhere. If the network drops, the app reconnects on its own.
10–30Fan-only mode
The fan can run alone 10, 20 or 30 minutes per hour to circulate basement air, even when there is nothing to dehumidify.
180 cfmPublished airflow
180 cfm with 8 in. ducts, per GeneralAire's spec sheet, which does not state the static pressure of the measurement.
< 55 dBPublished sound level
Under 55 dB unducted per the spec sheet. It can be ducted or free-standing, in a basement, crawl space or attic.
2.0 LWhat it removes per kWh
Each kilowatt-hour removes 2.0 litres of water from the air. At Hydro-Québec's Rate D, that's about 5.6 ¢ per litre.
40–60%The humidity range to aim for
The range recommended by ASHRAE. Above 60%, a home becomes prone to mold and mildew.
10 °CIt works in a cold basement
Operating range of 10.0 to 32.2 °C per the spec sheet: it keeps working in spring and fall, when the basement is still cool and damp.
MERV 11The filter
Filter: MERV 11, 10 × 12 × 1 in, replace every 6 months. It protects the coil and captures part of the particles in the basement air.
Built-inHumidity control is included
No wiring to an external control: plug it in and it manages the humidity on its own. A wall control is still possible when it's connected to ducts.
5 yrsThe parts warranty
Manufacturer's limited warranty on parts.
What it needs on site
In a finished basement, we put it in the mechanical room and connect it with ducts to keep the noise away from living spaces. Our estimator checks the location, the drain and the duct route before ordering.
