Your Smart Guide to Buying an ENERGY STAR Dehumidifier
Damp air can make your home feel sticky and even cause problems like mold. An ENERGY STAR dehumidifier removes extra moisture, making your space much more comfortable. This guide helps you pick the best one for your needs.
1. Key Features to Look For
When shopping, certain features make a big difference in how well your dehumidifier works and how much it costs to run.
Capacity (Pints per Day)
This tells you how much water the machine can pull out of the air in 24 hours. You must match this to the size of your room.
- Small Spaces (e.g., a small bathroom): Look for 20–30 pints.
- Medium Spaces (e.g., a basement room): Look for 30–40 pints.
- Large Areas (e.g., a whole damp basement): Look for 50 pints or more.
Energy Efficiency (The ENERGY STAR Label)
This is the most important part! ENERGY STAR certified models use about 20% less energy than standard models. This saves you money on your electric bill over time.
Drainage Options
You need a way for the collected water to go somewhere.
- Bucket/Reservoir: You must empty this manually. Good for areas you visit often.
- Continuous Gravity Drain: You attach a hose that lets water flow out naturally (downhill). This is great for basements where you don’t want to empty the bucket daily.
- Built-in Pump: This feature pushes water up and out, even if the drain is higher than the unit. It costs more but offers the most convenience.
Operating Features
Look for a built-in humidistat. This lets you set a target humidity level (usually between 40% and 50%). The machine turns off when it hits that level, saving energy.
2. Important Materials and Build
The quality of the materials affects how long your machine lasts.
- Casing: Most units use durable, hard plastic. Check reviews to see if the plastic feels sturdy or cheap.
- Coils: The evaporator and condenser coils are the parts that cool the air. Better models use corrosion-resistant coatings, especially important if you plan to use the unit in a humid basement where moisture might linger on the metal parts.
3. Factors That Improve or Reduce Quality
What makes one unit better than another?
Factors That Improve Quality:
- Automatic Defrost: If the temperature in the room gets too cold (like a cool garage), ice can build up on the coils. A good unit automatically stops cooling and runs the fan to melt this ice. This prevents damage.
- Low-Temperature Operation: Some dehumidifiers work well even when the temperature drops below 65°F (18°C). Standard models struggle in cooler air.
- Quiet Operation: Look for decibel (dB) ratings. Anything under 55 dB is generally considered quiet for a home appliance.
Factors That Reduce Quality:
- Cheap Compressors: The compressor is the heart of the machine. A low-quality compressor will break sooner or make much more noise.
- Small Water Buckets: If the bucket fills up too fast, the unit shuts off until you empty it. This means the humidity level rises again, defeating the purpose.
4. User Experience and Use Cases
How you plan to use the dehumidifier greatly affects what you should buy.
Basement Use
Basements are often cool and damp. You need a model rated for low temperatures with a continuous drain option. Since you might not visit the basement daily, a pump is very useful here.
Laundry Room or Bathroom Use
These areas produce quick bursts of high humidity. You need a fast-acting unit with a simple manual emptying bucket, as you are usually nearby to empty it.
Noise Level
If the unit sits near a bedroom or living area, noise is critical. Always check user reviews specifically mentioning how loud the machine runs on high speed.
Top 10 FAQs About ENERGY STAR Dehumidifiers
Q: What does ENERGY STAR certified actually mean for me?
A: It means the dehumidifier meets strict guidelines for energy efficiency set by the government. It uses less electricity than a non-certified model of the same size. You save money!
Q: How do I choose the right size (pints)?
A: You match the pint rating to the square footage of the damp area. Always check the manufacturer’s chart, but generally, the damper the room (e.g., a musty basement), the higher the pint rating you need.
Q: Can I run the dehumidifier all the time?
A: Yes, especially if you have a persistent moisture problem. Because it is ENERGY STAR rated, running it continuously costs less than running an older, standard unit.
Q: What is the ideal humidity level for a home?
A: Most experts recommend keeping indoor humidity between 40% and 50%. This level stops mold growth and feels comfortable.
Q: What happens if I don’t empty the bucket?
A: The machine will usually shut off automatically when the bucket is full to prevent water from spilling onto your floor. It will not run again until the bucket is emptied.
Q: Does a dehumidifier cool the room down?
A: Yes, slightly. Dehumidifiers work by cooling coils, which naturally releases a little bit of warm air out the back. It acts like a small space heater, not an air conditioner.
Q: Is there a difference between a dehumidifier and a portable air conditioner?
A: Yes. A dehumidifier only removes water from the air. An air conditioner cools the air *and* removes moisture. If cooling is your main goal, buy an AC unit.
Q: Do I need a pump if I have a gravity drain hose?
A: Only if the drain hose empties into a sink or drain that is physically higher than the dehumidifier itself. Gravity only works downhill.
Q: How often should I clean the filter?
A: You should clean the reusable air filter at least once every two weeks. A clogged filter makes the machine work harder and use more energy.
Q: Are portable dehumidifiers effective in large open-plan areas?
A: They work best in contained spaces. For very large, open areas, you might need a high-capacity unit, or you might need to install a whole-house dehumidifier system.
