If the dehumidifier is in a frequently used area or if your basement is particularly damp, the tank can fill up quickly, requiring frequent manual emptying. This is where drainage options become essential.
The most common drainage option is a manual drain tank. While convenient for smaller units or less humid environments, it can be inconvenient for a consistently damp basement. Many dehumidifiers offer a continuous drainage option, which allows you to connect a hose to the unit and direct the collected water directly to a floor drain, sump pump, or even outside (if feasible). This is a game-changer for basement use, as it eliminates the need for constant monitoring and emptying of the tank, making it a more set-it-and-forget-it solution. Some advanced models even include a condensate pump, which can push the water upwards to a suitable drainage point, offering even greater flexibility in placement.
4. Noise Level
Basements can sometimes double as living spaces, guest rooms, or even home offices. In such cases, the noise level of the dehumidifier can be a critical factor. Dehumidifiers, like most appliances with compressors and fans, do produce some noise. While you can’t expect complete silence, some units are significantly quieter than others. Look for models that advertise low noise levels, often measured in decibels (dB). Generally, a unit operating below 50 dB is considered relatively quiet and should be tolerable even if the basement is occasionally occupied.
Read customer reviews and product specifications carefully to get an idea of the actual noise output. Some manufacturers will provide a decibel rating for their dehumidifiers. Additionally, consider where you will be placing the dehumidifier within your small basement. Placing it on a carpeted surface rather than a hard floor can help absorb some of the vibration and noise. Some units may also offer different fan speeds, with the lower settings typically being quieter. If noise is a major concern, prioritize models specifically designed for quiet operation.
5. Humidistat and Auto-Defrost Features
A built-in humidistat is a standard feature on most modern dehumidifiers, but its quality and precision can vary. The humidistat allows you to set your desired humidity level, typically between 30% and 80%. The dehumidifier will then automatically cycle on and off to maintain that level, ensuring your basement doesn’t become too dry or too damp. This not only provides optimal comfort but also contributes to energy efficiency by preventing the unit from running unnecessarily.
Another crucial feature, especially for basements that can experience cooler temperatures, is the auto-defrost function. Dehumidifiers work by cooling coils to condense moisture. In cooler environments, these coils can freeze up, reducing the unit’s efficiency and potentially damaging it. An auto-defrost feature automatically detects ice buildup on the coils and temporarily switches off the compressor, allowing the coils to thaw. This ensures the dehumidifier can operate effectively even in cooler basement conditions and extends its lifespan. If your small basement is prone to lower temperatures, prioritize models with a reliable auto-defrost system to guarantee consistent performance.
6. Portability and Durability
While your small basement might have a designated spot for the dehumidifier, you might also want the flexibility to move it if needed. Most dehumidifiers are equipped with caster wheels and side handles, making them easier to transport. However, the build quality and overall portability can differ. Look for units that feel sturdy and well-constructed. Consider the weight of the unit, especially if you anticipate needing to move it regularly. A lighter unit with good wheels will be much more manageable.
Durability is also paramount, as a dehumidifier is an investment. Basements can be harsh environments with fluctuating temperatures and humidity. Choose a dehumidifier from a reputable brand known for producing reliable appliances. Check for features like robust casing, corrosion-resistant components, and good ventilation to prevent overheating. Reading reviews from other users who have owned the dehumidifier for a significant period can provide valuable insights into its long-term durability and performance in real-world basement conditions. Investing in a durable unit will save you money and hassle in the long run, ensuring your small basement remains comfortably dry for years to come.
