Where to buy

Before you buy

  • Compare DOE pints Use the 2019 DOE capacity; older AHAM figures look bigger for the same machine.
  • Get a pump or drain A built-in pump lifts water to a sink or window; otherwise you need a floor drain or empty the bucket.
  • Check the cold limit Frigidaire rates ours to 41 °F; Midea’s Cube defrosts itself when coils frost. The Cube we list is US only.

Drying questions

How fast must a basement dry after a flood?

Health Canada says to dry the area within about 48 hours, with fans or dehumidifiers, to limit mould. Run the dehumidifier with windows and doors shut, and empty or drain it continuously.

What has to come out after a flood?

Health Canada says to discard soaked flooring, and drywall, insulation, carpet, mattresses and particleboard furniture that flood water reached and that can’t be dried. Anything soaked by sewage may have to go too. Photograph everything for your insurer first.

Is it safe to run gas equipment while drying?

Not indoors. Health Canada warns that gas-powered pumps, heaters and dryers used inside to dry a basement cause carbon monoxide build-up. Use electric equipment on a safe circuit and keep a working CO alarm.
