How we decide what fits.

Where the numbers come from

Each unit's dimensions, voltage, venting, and drain requirements trace to a source record with a URL, an access date, and a verbatim excerpt. Of 20 spec sources behind the 20 live units, 13 are manufacturer spec sheets; the rest are major-retailer spec tables used as corroboration. Where a manufacturer PDF wasn't machine-readable, we mark the record's confidence accordingly.

How the fit verdict is computed

The fit finder runs one function against every unit. For your entered closet:

• Dimensions. A unit fits an axis when its body width/depth/height is within your closet dimension minus the clearance you asked to keep. Any axis short by a hair (≤1 in spare) is flagged tight, not fits.
• Door frame. If you give a door-frame width, the unit's body width must clear it to get into the room.
• Door swing. If a unit's door-open depth exceeds your closet depth, we flag that you'll load it with the closet/room door open — it doesn't fail the fit.
• Power. A 240V unit needs a 240V circuit; a 120V unit passes on either.
• Venting. A vented unit needs an exhaust duct; ventless (condenser/heat-pump) and all-in-one combos pass when you can't vent.
• Drain. Units needing a permanent drain fail if you have none; portables that use a faucet adapter are marked separately.

Whatever decides the verdict is named on the card — "taller than the space by 1.4 in", "needs a 240V circuit", "fits with 2.1 in of margin". The same function powers the "does it fit your space" check on each unit page, so there's one source of truth.

What this is not

This is a published-spec lookup, not an installation guide and not a guarantee. Real installs vary by vent run, water-line position, floor level, and how a delivery crew reads a doorway. Clearance figures are the manufacturer's required minimums. Always confirm the exact opening, door path, and hookups before you buy — and keep the return window in mind.

Keeping it current

SKUs turn over on roughly one-to-three-year cycles. We re-verify specs and merchant links on a cadence; discontinued models keep their reference page but drop out of the finder.
