A dehumidifier under a floor is out of sight. A summer thunderstorm knocks the power out, the unit stays off, and nobody finds out until the following spring when the boxes smell again.

Memory restart brings it back on its own settings when the power returns, so the outage costs you an hour rather than a season. The panel on the wall upstairs shows the live humidity, so a glance on the way past tells you it is still doing its job.

Hung from the joists or sat on the ground

Fourteen inches is the height that lets a machine this size go under a floor at all. Hanging it clears the walking route and keeps it out of anything that pools after heavy rain. Standing it is quicker where the ground is dry, and the four threaded feet take out the wobble on rough concrete. Fix any hanging hardware into solid framing and plan on two people for the 80.5 lbs.

Thirty two feet of cable is the whole idea

The panel is not attached to the machine. It runs on a 32.8 ft cable and screws to a wall wherever you actually want to read it, which is usually the hatch, the garage or the room above. It shows the humidity under the floor as a live number. Behind it sit three modes, a 24 hour timer, and a target you can set anywhere between 20% and 90%.

The rooms this class of machine is built for

Crawl spaces, unfinished basements, garages, warehouses and drying out after water damage. None of them are places you sit, which is why 58 dB and a metal cabinet are the right trade. The 20% lower limit and continuous drying mode are what separate this from a machine designed to keep a bedroom comfortable.

Two handles and one filter

There is very little to maintain. The mesh across the intake pulls out, rinses under a tap and goes back, and that is the job that keeps performance where it should be. The handles are moulded into each end of the cabinet, and the levelling feet thread up and down. Nothing here needs a consumable or a service visit.

32.8 ft of cable puts the display where you walk past it, so you never have to crawl in to see what the humidity is doing.

The manufacturer lists this model as CSA certified. That is the Canadian electrical safety mark, which matters on a permanently installed machine.

192 pints a day at 95F and 90% RH, 160 at 86F and 80%, 100 at 80F and 60%, and 65 on the 2019 DOE test.

Comes back on its own settings after a power interruption instead of waiting for someone to notice.

The manufacturer credits auto defrost for low temperature operation. It clears frost from the coil rather than letting it block airflow.

Enough air movement to reach the far end of a long crawl space, which is what the 2,600 sq ft coverage figure depends on.

A 9.8 ft drain hose comes in the box. An external condensate pump can be added through the built-in interface and is sold separately.

115V, 60Hz, 7.9A rated and 11A maximum, on a 9.2 ft cord. An ordinary grounded Canadian outlet, but not one shared with other heavy loads.

Ships from our Canadian or United States warehouse depending on where this item is stocked when you order. United States stock usually reaches Canada in 8 to 14 business days, with no customs charges or duties either way. Free shipping on orders over $150, a flat $18.90 below that, and tracking by email as soon as it leaves.

Return within 14 days of purchase, unused, in original condition and packaging.

Covered directly by the manufacturer under their warranty terms for material and manufacturing defects.

Found it cheaper at a Canadian retailer? Send us the link and we will match that price. It has to be the same item, in stock, sold and shipped inside Canada, and compared like for like on what comes in the box.

2,600 sq ft of rated coverage on a single machine, which saves running and servicing two.

Wall mounted panel, memory restart, auto defrost and a filter you rinse. Nothing about it asks for weekly attention.

Continuous drying mode runs without a target, and 20% is low enough to move construction moisture out of timber and slab.

A compressor machine with auto defrost suits a cool crawl space. Somewhere that regularly freezes needs a desiccant unit instead.

What we stand behind

• Ships from our Canadian or United States warehouse, free shipping over $150, and 14 day returns unused in the original packaging.
• 14 day returns on unused items in original condition and packaging
• Covered by the manufacturer's own warranty for material and manufacturing defects
• CSA certified by the manufacturer, with the 9.8 ft hose and the 32.8 ft panel cable included

How far from the machine can the control panel go?

The external connection cable is 32.8 ft. That is normally enough to bring the panel up through an access hatch and onto a wall in a garage, a utility room or a hallway. Mount it somewhere you pass regularly, since the number on the display is the live humidity under the floor.

Is 192 pints or 65 pints the number I should compare?

65 pints. That is the 2019 DOE test, measured at 65F and 60% relative humidity, which the US Department of Energy moved to because it reflects a cool basement rather than tropical air. The 192 pint figure is measured at 95F and 90%. Both are published for this machine, and every brand's headline number is flattered the same way.

What maintenance does it need?

Rinse the mesh filter under a tap and put it back. That is the routine job, and it needs doing more often in a dusty crawl space or on a construction site than it would upstairs. There is no cartridge to buy and no tank to empty, since the machine drains through a hose.

Does it run on an ordinary outlet?

Yes. It is specified at 115V, 60Hz with a rated input current of 7.9A and a maximum of 11A, on a 9.2 ft cord. That is a standard grounded Canadian outlet, but at 11A peak it should have the circuit to itself and should not run through a light duty extension cord.
