Waykar CTH150PB 150-pint ENERGY STAR dehumidifier review

The Waykar CTH150PB is the pump-equipped, auto-swing member of the CTH-B home dehumidifier family. Its 150-pint headline is a maximum at 95°F/90% RH; the EPA ENERGY STAR entry reports 49.43 pints per day under Appendix X1. The feature that distinguishes this exact offer is its pump: the family manual gives a maximum vertical pump height of 16.4 feet. That is a useful installation limit, not a promise that every hose route will work.

I matched the CTH150PB SKU to the selected variant and pump-linked image on Waykar’s CTH product page, inspected the manual sections for CTH150PB, and checked the EPA CTH150PB record. The pump feature is specific to this SKU; the standard CTH150B does not include it.

Keep the rating conditions and pump limit separate

The manual lists 50 pints/day at 65°F/60% RH, 75 at 80°F/60% RH, 123 at 80°F/80% RH and 150 at 95°F/90% RH. The exact EPA Appendix X1 figure is 49.43 pints/day. Thus it passes a 35-pint standard-condition filter but falls short of a strict 50-pint requirement, even though the manual’s cooler-condition table rounds to 50. EPA lists 2.20 L/kWh integrated energy factor, 471 kWh annual energy use and ENERGY STAR Most Efficient status in the captured product record. Those figures enable comparison but do not forecast your bill or the moisture load of a room. The manual gives 750 watts rated input at 115 volts/60 Hz.

On the pump page, Waykar identifies CTH150PB as the only pump model and specifies maximum vertical drainage height as 5 meters/16.4 feet. The pump hose must be attached before enabling pump mode; the manual says it begins when the internal reservoir reaches its maximum level, rather than immediately. It also instructs you to empty the tank if the full-tank alarm is triggered before activating the pump. Keep the distinction clear: the 16.4-foot value is a documented vertical-height ceiling, not a verified total horizontal-plus-vertical hose reach or a guarantee for a kinked route. If your outlet is higher than 16.4 feet, this source does not support the installation.

What you get besides the pump

The CTH150PB shares the 150-pint tier with the CTH150B and has a 1.9-gallon (7.1-liter) collection tank. It also supports the family’s gravity-drain route: Waykar lists a 3.3-foot hose, while the manual calls for a smooth downhill route with the drain outlet at least 3.94 inches below the drain port. The tank remains part of the product. The manual does not establish that it can operate bucketless, so do not treat a pump as proof that the collection tank can be removed or ignored.

The CTH150PB uses the automatic moving outlet deflector shown for B-code models. The manual describes up-and-down swing that can be turned on or off. Dry, Laundry and Sleep modes, three ordinary fan speeds, a 30%–80% RH target in 5-point steps in Dry mode, a 24-hour timer and automatic defrost are also documented. Sleep mode fixes the fan at low rather than allowing manual speed adjustment. Waykar estimates coverage up to 7,500 square feet; its gallery carries a 220-CFM claim for the 150-pint size. These are manufacturer figures, not independent room tests.

Placement, controls and unknowns

The manual sets the operating range at 41°F–90°F, asks for at least 54 square feet of area and 18 inches of clearance around the appliance. Check access to a grounded outlet, a place to collect water and the full intended pump route before moving the unit in. The reviewed product page and manual do not give cabinet dimensions, net weight or a sound-level number. “Super quiet” is marketing language, not an acoustic measurement. The EPA record says the product is not connected-capable; no app control is established.

Who should choose the CTH150PB?

It is the strongest fit in this family when a pump route is essential, the required vertical height is no more than 16.4 feet, and the 49.43-pint standard rating suits your actual threshold. Compared with CTH150B, moisture capacity, tank size and published energy figures are the same; you are paying for the pump option, not a higher rated capacity. Compared with CTH120B, both standard rating and tank volume increase, while the CTH120B remains a gravity-or-tank model. Skip the CTH150PB if your essential requirement is 50 standard-condition pints, a specified horizontal hose reach, app operation, a decibel limit or bucketless use—the reviewed sources do not establish those conditions. Verify the exact “CTH150PB” code; the same product page also exposes a fixed-vent pump SKU that is outside this review.
