Waykar YDZ-150 ENERGY STAR Portable Dehumidifier review

The Waykar YDZ-150 and YDZ-150PM share the same published 50-pint/day ENERGY STAR rating; “150 pints” is the higher 95°F/90% RH maximum. This non-pump YDZ-150 is the relevant choice when that standardized output is enough and a bucket or lower gravity outlet will work. It does not acquire an uphill drain just because the closely named 150PM does.

This assessment uses Waykar’s exact YDZ-150 listing, its manual download index and the YDZ-80/120/150/150PM manual, along with the exact ENERGY STAR YDZ-150 record. The manufacturer page’s structured SKU is AZ-YDZ-150 and the collection calls out YDZ-150; the manual and EPA record use the same code.

Waykar’s exact YDZ-150 page links this white cabinet exterior. It shows the controls, front water-level window and casters, but not a model plate or operating performance.

Separate maximum capacity from the comparable rating

The product page’s 150-pint figure applies at 95°F/90% RH. The shared manual gives 50 pints/day at 65°F/60% RH, 72 at 80°F/60% RH and 120 at 86°F/80% RH; the ENERGY STAR record independently lists 50 under Appendix X1. For a cross-model requirement, use the 50-pint certified figure, not the hot-and-wet maximum. This supports a 50-pint minimum, but not a 60- or 100-pint standardized minimum. The page’s “up to 7,000 square feet” claim is not a guarantee that one unit will manage a connected set of rooms or a specific moisture source.

ENERGY STAR lists 2.02 L/kWh IEF and 522 kWh annual use. The manual’s table gives 2.01 L/kWh. The small discrepancy is preserved; the finder uses the exact certified record’s 2.02. That listing says ENERGY STAR certified, not Most Efficient, and Connected Capable: No. Annual use is not a personalized operating-cost estimate, and the record does not document phone control.

The distinction from YDZ-150PM is the drain route

The YDZ-150 supports bucket collection and gravity drainage, but the manual identifies the built-in condenser pump as applicable only to YDZ-150PM. If the outlet is above the unit, the non-pump model is not a fit. If your outlet is lower, its included 3.3-foot hose may be relevant, provided it reaches continuously downhill. The manual’s gravity instructions tell the owner to keep the line clear and sloping; a separate note gives a 23.62-inch maximum drain length, inconsistent with the 3.3-foot included-hose description. Treat the route as a documented feature, not as a verified universal reach. Confirm the intended placement and route before relying on it.

The manual says the removable tank is 7 liters/1.8 gallons for the YDZ-150 and YDZ-150PM; the exact product page calls it 7 liters/1.85 gallons, a near-identical rounded description. A full-tank alarm stops operation until the tank is emptied and returned. That tank is useful if you will monitor and empty it, but it does not replace a pump or establish a bucketless mode. The manual does not confirm operation without the tank installed, so an essential bucketless requirement remains unmet.

Control and placement are still household constraints

The manual describes 30–80% humidity selection in five-point steps, AUTO and CONTINUOUS modes, high/low fan settings, a 1–24-hour timer, automatic air swing and automatic defrost. The self-drying cycle takes about 50 minutes and needs to be started at the controls; it runs at high fan for 30 minutes and low for 20. It is not the same as assuming that the appliance automatically sanitizes itself every time it powers down. The control panel is not backed by documented app operation; EPA’s exact model record says Connected Capable: No.

The family manual gives 115 V/60 Hz and 460 W at 65°F/60% RH, R32 refrigerant, and a recommended 41–90°F operating window. It also warns that this appliance must be positioned, used and stored in an area of at least 8.9 m² (96 sq. ft.). Automatic defrost does not erase the lower temperature limit. The product page does not label all physical dimensions by axis; measure the route and footprint rather than using an unlabeled overall number as a width promise.

Who should choose the non-pump version?

It belongs on a shortlist when the independently listed 50-pint standard rating is sufficient, an ENERGY STAR-certified portable appliance is desired, and water can be collected by hand or moved to a lower drain within a verified hose route. Compared with the YDZ-120, it raises the EPA-listed standardized figure from 35 to 50 pints/day. Compared with the 150PM, it gives up uphill pumping while keeping the same 50-pint standardized rating and EPA IEF. That is a meaningful water-handling distinction, not a capacity upgrade.

Look at YDZ-150PM only when the route needs an upward lift; the manual documents 16.4 feet maximum vertical pumping for that exact model. Choose neither based on the 150-pint headline alone, and do not assume app control, a precise gravity-hose reach, a bucketless setup or below-41°F use. The right fit depends on the test-condition rating and the water path you can actually install.
