TABYIK 35 OZ Dehumidifier (DH-CS01): problems, parts and running costs

Checked: 2026-10-05

Summary

The core problem is capacity: independent testing measured only 0.2 L per day at 77°F, far below the seller’s 450 mL maximum that assumes 86°F and 80% RH, and there is no humidistat, drain or pump so the tank is emptied by hand. The only running cost is electricity, and at the measured 34 W draw continuous use is about 298 kWh a year while removing little water. It is worth it only at the low end of its price band, for a genuinely small, warm, enclosed space where quietness and size matter more than drying power.

Common problems and fixes

Far weaker than advertised — RTINGS tested the exact White unit and measured 0.2 L per day at 77°F against the seller’s 450 mL per day at 86°F and 80% RH; treat the claim as a favorable-condition maximum, not expected output. [1]
No humidistat, drain or pump — nothing maintains a target humidity setpoint and there is no hose or continuous drain, so the 1,000 mL tank must be emptied by hand, with full-tank shutoff around 700 to 800 mL. [1]
Loses ability as conditions cool — Peltier performance falls as air gets cooler and drier, which is why RTINGS rated it poor for basement use; it is not a wet-room or damp-basement fix. [1]
No defrost on the White revision — the exact White model has no defrost despite auto-defrost wording on newer color pages, so do not expect that feature on this listing. [1]
Early failure signal — several owner reports describe no power, a dead fan, or a unit that keeps running but stops collecting water after one to several months, while other owners report years of service; that is a signal, not a failure rate. [3]
Noise is higher than claimed — the seller states 28 dB while RTINGS measured 38.1 dBA, still quiet but not as silent as the listing implies. [1]
Weak support and unverified warranty — no strong first-party support or parts channel was found, and the commonly repeated two-year warranty comes from retailer metadata rather than a verified TABYIK policy. [3]

Parts and consumables

No filter or consumable — maintenance is just keeping the inlet and outlet clear, rinsing the removable tank and cleaning the air path; there is nothing to buy or replace on a schedule. [1]
External power adapter — the unit runs from an external adapter, so a replacement is possible if correctly specified, but no official exact-model parts catalog or replacement price was found. [1] [2]

Yearly running cost

Electricity only, and it is not trivial. At the measured 34 W draw, continuous operation is about 0.816 kWh a day, about 24.5 kWh a month and roughly 298 kWh a year, which can rival or exceed the purchase price over a year while removing little water per unit of electricity. There is no filter to replace. [1]

When it is a good buy

No non-Amazon store price was captured in the sources, so no store-and-month figure can be quoted. The researched value bands are: $25 or less excellent for a closet, RV or tiny warm room if expectations are light-duty; $26 to $35 good; $36 to $40 fair if quietness and footprint matter; $41 to $47 mediocre; above $47 poor unless the tiny form factor is specifically required. [3]

ProBreeze PB-02 or PB-03 and Eva-Dry EDV-1100 — the same thermoelectric class; RTINGS found the TABYIK removes more moisture than the PB-02 and Eva-Dry and is quieter than the PB-03, so compare on price and noise rather than capacity. [1] [2]
A compact compressor or refrigerant dehumidifier — the better choice when the goal is to actually lower humidity in a damp basement or larger room, since this class removes far more water per kilowatt-hour. [1] [3]
