Waykar CTH80-D fixed-vent dehumidifier review

Waykar’s CTH80-D is the fixed-vent 80-pint selection on the CTH Pro page. The manufacturer’s table rates that label at 95°F and 90% relative humidity, a hot, very humid condition—not the cooler standardized figure used by the finder. The exact listing supports a fixed outlet and gravity-drain capability, but its manuals do not clearly bridge the hyphenated model code. Treat it as a distinct SKU, and do not borrow the more complete CTH80D figures.

The Waykar U.S. listing identifies variant 48173509837038 as CTH80-D, GTIN 721820976435, “80 Pints / Fixed Vent.” Its page-level specification table states 80 pints per day at 95°F/90% RH and lists gravity drainage. The linked quick guide names B-suffixed models, while the separate CTH-D manual uses the unhyphenated CTH80D code; neither is a model-specific guide for this exact SKU.

Read the capacity label in its stated conditions

The 80-pint label is useful only when you keep the test conditions attached to it. Waykar’s table says the 80/120/150-pint capacities are measured at 95°F and 90% RH. It does not give a CTH80-D-specific result at 65°F/60% RH, so this page does not establish the number needed for a strict standard-condition capacity filter. A hot, damp room and a cool basement can produce very different extraction; do not translate the 80-pint headline into a promise about a typical room.

The CTH family page also calls the range ENERGY STAR certified, but the hyphenated CTH80-D code is not matched to a separate certification record in the material reviewed for this exact selection. That is not proof the claim is false; it is a reason not to treat the record as model-confirmed in a filter. The same caution applies to the page’s several coverage-area and airflow numbers: they are presented for the wider product family without a clear model-to-value mapping here.

Fixed vent changes where you put the unit

“Fixed Vent” is the important configuration choice. It is not the automatically moving outlet on the CTH80B selector. Plan the room around a fixed discharge direction rather than expecting the machine to sweep air across the space. That may be acceptable beside an open basement area, but it is a poor fit if a moving outlet is essential to your setup. The manufacturer does not publish a decibel measurement alongside the “Super Quiet” wording, so a quiet-room requirement cannot be checked from a number.

Gravity drainage is listed; tank details are not

Waykar’s table says gravity drainage is supported and gives a 3.3-foot figure. It does not, in that table, say what hose is included with this hyphenated selection, how much fall the route needs, or the tank’s capacity. A lower drain near the appliance may make the gravity option practical, but confirm the hose and installation instructions for SKU CTH80-D before building a permanent route. Do not assume the 1.2-gallon tank described for CTH80B/CTH120B also belongs to this different selector.

The CTH80-D fixed-vent selection is not labelled “with pump.” The same page’s 16.4-foot pump-drain figure names CTH150PB, a different model string and automatic-swing option; it cannot be assigned to CTH80-D. If your drain sits above the unit or pump operation is essential, choose a model with a matching manual and stated lift rather than relying on the CTH80-D page’s general drain table.

How the finder should handle this exact code

With no capacity or drain requirement, the exact current listing can remain visible as a possible fixed-vent choice. A standard 20-pint minimum should not select it because the corresponding standardized rating is unknown, not because the machine is known to fall below 20. An automatic-swing requirement correctly rules it out. The listed gravity route may satisfy a basic gravity-drain need, but bucket collection, bucketless operation, pump lift, app control, and a precise low-temperature operating limit are not established for this SKU.

Compare codes before you buy

Waykar also lists a CTH80D without the hyphen and a CTH80B with auto swing. The unhyphenated CTH80D has a separately named manual and exact Appendix X1 rating; the B model has its own manual and EPA record. Their separate variant IDs and GTINs mean their data should not be silently carried over to CTH80-D. If you want a documented lower-condition capacity, tank size, or detailed drainage route, compare those exact codes and confirm the label on the item you intend to buy. The CTH80-D makes the most sense only when its exact fixed-vent identity, warm/humid headline rating, and limited drainage documentation fit your plan—and you are comfortable verifying the missing installation details first.
