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 90: 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
$100
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.
WallA humidity control to plan for
Unlike the DR65, it has no built-in humidistat. It runs from an external control sold separately, such as the HumidiPRO H6062A1000 or a Prestige IAQ or VisionPRO thermostat. Our estimator includes it in the quote.
6 inIt can ventilate too
6 in. fresh-air inlet with a separate ventilation control: per the spec sheet, its fan can bring outdoor air into the house.
320 cfmAirflow that holds up with ducts
The spec sheet gives 320 cfm with no ducts and 215 cfm at 0.6 in. of static pressure.
LevelLevel, never above a coil
The installation guide calls for a level install, on the floor or a stationary base, and never above an air-conditioning coil.
90 → 47What it really removes in a basement
90 pints a day at 80 °F, 65 at 70 °F and 47 at 60 °F, always at 60% humidity: those are the numbers on the manufacturer's spec sheet. The cooler the air, the less it removes. Most sellers only show the first number.
2.9 LWhat it removes per kWh
Each kilowatt-hour removes 2.9 litres of water from the air. At Hydro-Québec's Rate D, that's about 3.8 ¢ 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.
1 °CIt works in a cold basement
Operating range of 1.1 to 57.2 °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, 14 × 17.5 × 1.75 in. It protects the coil and captures part of the particles in the basement air.
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.
