Waykar YDZ-150PM ENERGY STAR Portable Dehumidifier with Pump review

The Waykar YDZ-150PM is the pump-equipped member of a four-model family. Its 150-pint headline is the maximum under 95°F/90% RH; the ENERGY STAR record and manual both give 50 pints/day for the standardized 65°F/60% RH comparison. The pump is the substantive reason to pick it over the otherwise similar YDZ-150: it can send condensate uphill, to a documented vertical maximum of 16.4 feet.

This review draws on Waykar’s exact YDZ-150PM U.S. product page, the official manual download index and YDZ-80/120/150/150PM family manual, plus the exact ENERGY STAR YDZ-150PM record. The page SKU reads AZ-YDZ-150PM; both the manual and EPA record name YDZ-150PM.

The exact product page links this white YDZ-150PM exterior view with a drain hose visible at the left. The image does not show a model label or verify a pump route; the operating limits come from the manual.

Capacity remains 50 pints in a fair comparison

The model page describes 150 pints/day at 95°F/90% RH. The family manual lists 50 pints at 65°F/60% RH, 72 at 80°F/60% RH and 120 at 86°F/80% RH. ENERGY STAR separately lists 50 pints/day under Appendix X1. Its 2.02 L/kWh integrated energy factor and 522 kWh/year also match the YDZ-150 record; the manual’s table gives a slightly different 2.01 L/kWh. The finder uses the certified figure and leaves the discrepancy visible.

This rating meets a 50-pint standardized threshold but not 60 or more. The “up to 7,000 square feet” claim should not be treated as a promise for a particular basement layout or a measure of how quickly it will solve a water problem. Capacity depends on the test condition; the moisture source, temperature, airflow and connected rooms still matter. ENERGY STAR marks the exact model certified, not Most Efficient, and “Connected Capable: No” means app control is not a documented strength.

The pump changes where the water can go

The manual explicitly limits its built-in condensate pump to YDZ-150PM and gives a maximum vertical height of 16.4 feet. Waykar’s product page also advertises a 16.4-foot pump drain. That is useful if the nearest sink, drain or window route is higher than the unit. The manual shows a 0.19-inch inner-diameter pump hose; it does not state a maximum total hose length or combined horizontal-plus-vertical route. Measure the rise and ask the manufacturer about the full route if it is long. Do not interpret 16.4 feet as a total-distance allowance.

For a lower outlet, the manual also describes gravity drainage with a 3.3-foot included hose. It asks that the route slope down and not kink or clog, yet separately states a 23.62-inch maximum drainage length. That conflicts with the included-hose figure, so exact gravity reach remains unclear. The pump does not make every water arrangement effortless; it adds a route option whose hose path, discharge point and electrical placement still need planning. The manual does not confirm bucketless running, so an essential “no tank installed” requirement should not pass.

The removable collection tank is listed as 7 liters/1.8 gallons in the manual and 7 liters/1.85 gallons on the product page. It has a full-tank alarm and automatic stop. That is a modest rounding difference, but it still means the pump is not a substitute for checking that the tank, float and pump are correctly installed. If you plan to use pump mode, keep the model’s manual close and verify the required setup before leaving it unattended.

Controls, efficiency and installation notes

The manual documents a 30–80% RH target in 5-point increments, high and low fan speeds, AUTO and CONTINUOUS modes, a 1–24-hour timer, automatic outlet swing and automatic defrost. Its self-drying cycle is started at the control and takes about 50 minutes—30 minutes at high speed, then 20 at low. It is not evidence of app control or of a maintenance-free interior. The filter is removable for cleaning; the manual also gives a routine for cleaning the tank and drain port.

At 65°F/60% RH, the manual lists 460 W, 115 V/60 Hz and R32 refrigerant. It recommends use from 41°F through 90°F and states a minimum 8.9 m²/96 sq. ft. placement, operation and storage area. A low-temperature requirement below 41°F is not satisfied just because automatic defrost is present. Product-area claims are not a substitute for those operating conditions or for fixing a leak or drainage source.

When the pump is worth choosing

Choose the YDZ-150PM for comparison when a 50-pint standardized rating is enough and the actual water outlet is above the unit; its 16.4-foot vertical limit is the documented discriminator from YDZ-150. If the outlet lies below and the hose can reach, the non-pump YDZ-150 has the same EPA-listed capacity and IEF. The YDZ-120 drops to 35 pints under Appendix X1, while the YDZ-80 is 24; compare those figures rather than the 80/120/150 maximums on the titles.

Do not choose it for unknown bucketless operation, an app requirement, a cold location or a specific long pump-hose route that the manual does not rate. It is the right family member only when its documented lift solves a real layout constraint and you can verify the total route.
