The TABYIK 35 OZ Small Dehumidifier is designed for environments such as bedrooms, bathrooms, RVs, and closets up to 280 square feet. It features a 1000ml (35 OZ) tank, which can collect up to 16oz (450ml) of moisture per day in humid conditions, making it effective for small, closed spaces. The compact size (5.9 x 5.9 x 10.1 inches) and lightweight (2.19 pounds) design make it highly portable, ideal for moving between rooms or taking on the go.

Additionally, the dehumidifier operates quietly at 28dB, ensuring it won't disturb your sleep or work, and it has a colorful light feature to create a pleasant atmosphere. Its energy efficiency is notable, consuming less than 1-kilowatt hour per day, which is economical for continuous use. The auto shut-off function ensures safety by turning off the device when the tank reaches 700-800ml capacity and provides a visual alert with a red flashing light.

This feature is convenient and offers peace of mind, especially when you're away from home. However, the dehumidifier might require frequent emptying in very humid conditions due to its small tank capacity. The ease of use is enhanced by the visible water level in the transparent tank and the groove design, which makes tank removal simple.

The TABYIK mini dehumidifier is a compact and portable option designed for small spaces like closets, bathrooms, bedrooms, and even RVs. With a 42-ounce water tank, it can hold a decent amount of moisture before needing to be emptied, which suits occasional use in confined spaces. Its size is fairly small (about 11 inches tall), making it easy to place almost anywhere without taking up much room.

One of its biggest strengths is quiet operation, thanks to advanced semiconductor technology. This means it won’t disturb your sleep or daily activities, which is great if you plan to keep it in bedrooms or closets near living spaces. The unit also features an automatic shut-off to prevent leaks when the tank is full, adding convenience and safety. Energy use is moderate at 40 watts, so it won’t drastically increase your electricity bill, but it may not be the most energy-efficient model if you plan to run it continuously. The auto-defrost feature is a nice touch, allowing it to work reliably even in cooler environments, although it’s recommended to use it where the temperature stays above 68°F and humidity is over 60%. This makes it less ideal for colder or very damp basements.

Setup and operation are straightforward with easy-to-use controls and a removable tank for hassle-free emptying. The colorful LED lights add a pleasant ambiance but might be unnecessary for some users. This dehumidifier represents a solid choice for anyone seeking a quiet, hassle-free device for small, enclosed spaces like closets or RVs, but it’s not suited for larger or colder areas.

Its size (6x6x9 inches) and light weight (just over 3 pounds) make it easy to move and place discreetly in tight areas.

This model uses semiconductor technology, which helps it run quietly—a big plus if you want to avoid noise disturbances, especially in bedrooms or quiet closets. It also includes an automatic shut-off feature that stops the unit when the tank is full, preventing water overflow and giving you peace of mind if you forget to check it. The addition of seven color-changing LED lights can create a pleasant ambiance but might be unnecessary or distracting in some settings.

Controls are simple with just two buttons, making it easy to operate without a steep learning curve. The water tank size may require frequent emptying in very humid areas or larger spaces. While the device claims to cover 550 sq. ft., performance can vary based on room conditions.
