Buying Guide for the Best Energy Efficient Dehumidifier
Choosing an energy-efficient dehumidifier is a smart move if you want to manage humidity in your home, save on electricity bills, or reduce environmental impact. It’s important to focus on features that affect both how much moisture the device can remove and how efficiently it uses power. Understanding your room size, your local humidity, and typical use patterns can help you narrow down the best fit for your needs.Energy Efficiency (Energy Star Certification)Energy efficiency refers to how much electricity the dehumidifier uses compared to how much moisture it removes from the air. Look for the Energy Star certification, which means the unit meets certain government standards for being less wasteful. Energy efficiency is usually marked with labels or certifications. Generally, the more efficient the device, the lower your electricity bills. If you plan to use your dehumidifier frequently, choose one that lists a low energy consumption per liter or pint of water removed.
Capacity (Pints or Liters Per Day)Capacity tells you how much water the dehumidifier can remove from the air in a 24-hour period, usually measured in pints or liters. There are small, medium, and large capacity units. Small ones (up to 20 pints or about 10 liters) are for tiny spaces, like bathrooms or closets. Mid-sized units (20-35 pints or about 10-16 liters) suit bedrooms or offices. Large units (over 35 pints or more than 16 liters) work best in basements or large rooms. Pick a capacity that matches the size of your room and your local humidity—if your area is very humid, or the room feels damp, go for a bigger size.
Water Tank Size and Drainage OptionsThe water tank in a dehumidifier collects the moisture pulled from the air. A larger tank needs to be emptied less often, but may make the machine bigger or heavier. Some models offer continuous drainage, allowing you to attach a hose and direct the water straight to a drain, which is convenient for long-term use or very humid spaces. If you want a hassle-free experience for areas that get very wet, prioritize a larger tank or continuous drainage. For occasional use in smaller rooms, a smaller tank might be just fine.
Hygrostat (Humidity Control Settings)A hygrostat lets you set the target humidity level for the room. This feature is important because it keeps the environment comfortable and prevents over-drying, which can affect furniture and health. Basic models may have a few fixed settings, while better ones offer digital controls that let you choose the exact percentage. If you want precise control or have sensitive items like books or instruments, look for digital settings. If you just want general moisture control, simple settings may be enough.
Noise LevelNoise level tells you how loud the dehumidifier will be during operation, usually measured in decibels. Some people are sensitive to noise, especially if the device will run in a bedroom or living room. If you need a quiet environment, check for quiet or low-noise models—many will indicate this on the packaging or in product descriptions. For basements or places where noise isn’t an issue, this may be less important.
Automatic Shutoff and RestartAutomatic shutoff turns the dehumidifier off when the tank is full, helping avoid spills. Automatic restart kicks the unit back on after a power outage. These features are useful for convenience and safety. They are especially valuable if you can’t keep an eye on the machine all the time or if you will be running it continuously in a hard-to-access space.
