TOSOT 50-pint dehumidifier (TST-NDHM-50WHT), no pump review

The no-pump TST-NDHM-50WHT is the larger of the two TOSOT 50-pint listings in this family. Its exact page gives a 49.58-pint detailed rating, a 13-pint bucket and a ¾-inch gravity-drain connection. That combination favors a room with a lower drain or an owner willing to empty the tank; it does not offer the upward discharge option of the pump model.

Earlier model: TOSOT currently marks this exact product discontinued and unavailable. Keep it for identifying an installed unit or comparing a particular used/clearance offer, not as a current new-product recommendation.

TOSOT links this exterior image to the exact TST-NDHM-50WHT page. The same image bytes are used for the 20-pint, 35-pint and pump listings, so the cabinet view cannot identify this capacity or prove that a pump is absent. Photo-versus-render status is not stated.

Manufacturer references: the exact TST-NDHM-50WHT page, TOSOT Direct’s dehumidifier collection and its document index. TOSOT’s document portal maps GDN50BA-A3EBA2D to this TST-NDHM-50WHT product page and links its model-specific technical sheet, ENERGY STAR certificate and family manual. Their detailed capacity values agree at 49.58 pints/day.

What “50 pint” means on this exact page

The detailed capacity table lists 49.58 pints per day, while the comparison chart labels the 2019 DOE class as 50 pints per day and gives 70 pints under the older 2012 DOE standard. Those entries should not be flattened into one number: the detailed figure is just below a strict 50-pint numeric threshold, while the model’s rounded marketing class is 50. If your requirement truly means at least 50.00 pints/day, the exact detailed value does not clear that boundary. If you are comparing manufacturer class labels, the page places it in the 50-pint 2019 DOE class. Neither number predicts what a room will collect each day.

TOSOT’s chart suggests a 3,000–4,500-square-foot range, but its own FAQ says room humidity and size affect the choice. That suggestion is not a guarantee for a separated basement or a space with water intrusion. Temperature, humidity, circulation and incoming moisture change the actual amount removed. The unit’s listed operating range is 41–90°F, so a cold crawlspace or winter room outside that range is a different problem.

A larger bucket, but still no automatic lift

The 2-gallon tank holds 13 pints and slides out of the cabinet. That is larger than the 7-pint bucket on the 20-pint model and the 9-pint bucket on the 35-pint model, but it remains a finite container. The full-tank light and shutoff reduce overflow risk; they do not eliminate the need to check and empty it when collecting water. A full bucket is much heavier than an empty one, so do not carry it carelessly or use its nominal capacity as a safe lifting weight.

For continuous removal, the exact page lists a garden hose with a ¾-inch female connection. TOSOT describes that route as gravity drainage to a floor drain. The outlet therefore needs to be lower than the appliance and the hose needs a continuous downhill path. There is no built-in pump on this TST-NDHM-50WHT page, so it cannot meet a requirement to push water to a higher sink, window or drain. The page also does not establish bucketless use; the exact suffix should not be assumed to share another configuration’s arrangement.

Physical fit and controls

The cabinet is listed at 14.76 inches wide, 24.02 inches high and 11.38 inches deep. Its approximate dry weight is 43.7 pounds. Measure doors, the exact spot and the room for removing the tank; dimensions alone do not include all operating clearance. The page lists 115 volts, 770 watts and 7.2 amps, a five-foot cord, three fan speeds, automatic defrost, automatic restart, casters, washable filter, humidity settings from 35 to 80 percent and a two-/four-hour timer. TOSOT’s sound table gives 51, 49 and 47 dB for high, medium and low. Those are manufacturer specifications rather than independent tests.

For filter care, the exact page FAQ recommends warm-water/mild-detergent cleaning every 30 days of operation. The document portal maps this TST listing to GDN50BA-A3EBA2D on the family-manual cover; that manual has a 250-hour filter indicator. These are distinct manufacturer maintenance cues, so use the actual appliance reminder and the instructions supplied with it. Routine care also means keeping the airflow grille clear and checking that a gravity hose has not kinked or slipped out of its drain.

Choose the pump edition only for an actual raised outlet

For a lower floor drain, the no-pump model has the simpler documented arrangement: a fitted bucket or a gravity hose. It is not the right pick if water must travel upward. The separate TST-NDHM-50WHT-P page confirms a built-in pump and an included hose, but the official document portal maps that retail page to GDN50BA-A3EBA2F. The linked family manual’s pump instructions set an up-to-15-foot vertical/horizontal distance for this pump model, but do not state the included hose’s total length. The no-pump unit itself has no upward pumping route.

This discontinued model is most relevant to an existing owner or a buyer comparing a specific used listing who wants a larger tank and lower-gravity drain, not remote app controls or a pump. TOSOT does not document Wi-Fi on the exact page, and no independent removal, noise or energy tests were performed here. If the room is receiving water through a leak, repair that source; this appliance is a moisture-control tool, not a building repair.
