Waykar CTH80D 80-PPD dehumidifier review

The Waykar CTH80D is the 80-PPD fixed-vent selection in the CTH-D group. That headline is the warm, very humid test rating; ENERGY STAR lists 24.84 pints per day under the more comparable Appendix X1 conditions. This is the tank-and-gravity-drain version, not the CTH150PD pump model. Choose it only if its standard-condition capacity and the room’s water route fit your plan.

I matched the CTH80D SKU, variant 47993814089966 and GTIN 717623189943 on Waykar’s exact U.S. product page, then checked the CTH-D family manual and ENERGY STAR record 4591182. The manual also names a CTH150D, but that code is not one of the three options on this captured product page; this review is for CTH80D only.

Compare ratings on the same conditions

Waykar’s “80 PPD” selector label corresponds to the manual’s 95°F/90% RH test. At 80°F/60% RH the manual lists 37 pints per day, and at 65°F/60% RH it lists 25. ENERGY STAR’s Appendix X1 figure is 24.84 pints/day, so this model clears a 20-pint standard-condition filter but not a strict 25-pint minimum. The small difference between the manual’s rounded 25 and the EPA value matters if you use a hard threshold. Neither rating predicts the amount of water a particular room will remove; conditions and moisture load affect the result.

The EPA entry reports an integrated energy factor of 1.85 L/kWh, annual use of 283 kWh, and ENERGY STAR Most Efficient status. The manual’s rated input is 370 W at 115 V/60 Hz. These are useful comparisons, not a household bill estimate: runtime, humidity, temperature, and the chosen target all matter. The CTH120D steps up to 32.46 Appendix X1 pints/day with an IEF of 2.01; the CTH150PD reaches 49.43 and adds a pump, but uses a larger tank and is a different installation choice.

Plan for a fitted tank or a genuinely lower drain

The manual assigns the CTH80D a 4.6-liter/1.2-gallon collection tank. It describes a full-tank alert and automatic shutoff, so tank use means checking and emptying it rather than assuming continuous unattended collection. For continuous drainage, the manual shows a gravity port and a smooth downward hose route; the included gravity hose is 3.3 feet long. The outlet must be below the port, and the manual specifies at least a 3.94-inch drop. A level or uphill destination is not a gravity-drain setup.

There is no pump in the CTH80D operating plan. The product page’s family heading says “Pump Optional,” but the exact selector and manual distinguish the pump-equipped CTH150PD. Do not buy this model expecting it to lift condensate to a higher sink. The manual also does not confirm that the tank can be removed for bucketless use. If a raised drain is essential, compare the CTH150PD’s documented pump limit or another exact model whose pump and route match your installation.

Controls and placement are part of the fit

The CTH-D manual documents an automatic mode that changes its humidity target with room temperature: 55% RH below 64°F, 50% from 64°F to 77°F, and 45% above 77°F. In that mode the fan stays on low and the target and fan controls are not manually adjustable. Outside Auto Mode, the manual describes a 30%–80% RH target range in five-point steps and three fan-speed choices. A timer, power-restoration memory, full-tank protection, and automatic defrost are documented. The product page calls the outlet a fixed vent, so do not select it if an automatically moving air deflector is essential.

ENERGY STAR lists this model as not connected-capable; app operation is not established. The manual gives an operating range of 41°F–90°F, asks for at least 54 square feet of space and 18 inches of clearance around the unit, and illustrates caster wheels. It does not provide cabinet dimensions, net weight, or a decibel figure. “Super Quiet” in the listing is not an acoustic measurement. The exact product page’s specification text includes a tank table naming B-code models, so I rely on the D-family manual for the CTH80D tank size rather than transferring that table’s sibling values.

Who should consider the CTH80D?

It is a sensible match when a tank or lower gravity outlet works, a fixed outlet is acceptable, and a 24.84-pint Appendix X1 rating meets the actual need. It is not the right answer to a strict 25-pint-or-higher requirement, a pump-lift requirement, app control, bucketless operation, or a specific sound or cabinet-size limit. Before ordering, check the complete code: CTH80D is the fixed-vent 80-PPD selector; the CTH80B is a different auto-swing model. The shared CTH-D illustration on Waykar’s page does not identify a capacity variant, so use the selector code—not the picture—to confirm the configuration.
