Your Garage Dehumidifier Buying Guide
Garages often become damp and musty. This moisture can damage tools, cars, and stored items. A dehumidifier is your best friend for keeping your garage dry. This guide helps you pick the right one.
Key Features to Look For
When buying a garage dehumidifier, several features matter most.
Capacity Matters Most
Dehumidifiers come in different sizes, measured by how many pints of water they remove per day (PPD).
- **Small Garages (Under 500 sq. ft.):** Look for 30-50 PPD models.
- **Medium Garages (500-1000 sq. ft.):** Aim for 50-70 PPD.
- **Large or Very Damp Garages (Over 1000 sq. ft.):** You need 70 PPD or higher.
Continuous Drainage is Crucial
Most dehumidifiers collect water in a bucket. You must empty this bucket often. For garages, continuous drainage is better. This feature lets you attach a standard garden hose. The water drains directly out of the unit and often down a floor drain. This saves you lots of trips.
Defrost Function
Garages often get cold, especially in winter. Standard dehumidifiers freeze up when temperatures drop below 65°F. Look for a Low-Temperature Operation or Auto-Defrost setting. This prevents ice buildup and lets the machine work efficiently even when it is chilly.
Portability and Durability
You might need to move the unit. Check for sturdy wheels and handles. Since garages can be rough environments, look for durable plastic casings.
Important Materials and Build Quality
The quality of materials affects how long your dehumidifier lasts in a demanding garage setting.
Compressor Type
Most units use a compressor, similar to a refrigerator. A high-quality compressor runs quieter and lasts longer. Read reviews to see if users report loud noises or early failures.
Coil Material
The coils inside the machine remove moisture. Coils coated with epoxy resist rust better than bare metal. Rust ruins a dehumidifier quickly, especially in damp environments. Good coating improves the machine’s lifespan.
Factors That Improve or Reduce Quality
Several design factors make one dehumidifier better than another for garage use.
Higher Operating Temperature Range
The best garage dehumidifiers operate well down to 40°F or even 38°F. If your garage regularly dips below this, you must choose a specialized, low-temperature model. A unit that stops working in the cold is a waste of money.
Energy Efficiency
Dehumidifiers use electricity. Look for the Energy Star certification. Energy Star rated units remove more water for the same amount of power. This lowers your monthly utility bills.
Noise Level
While garages are often noisy spaces, a very loud dehumidifier can still be annoying. Units under 55 decibels (dB) are generally acceptable.
User Experience and Use Cases
How you plan to use the garage shapes your decision.
Workshop/Woodworking
If you work with wood, humidity control is vital for material stability. You need consistent, reliable performance. Prioritize a large capacity and continuous drainage so you don’t interrupt your work flow to empty a bucket.
Simple Storage Area
If you just store old boxes and seldom-used items, a smaller, less powerful unit might suffice. Focus on affordability and basic moisture removal.
10 Frequently Asked Questions (FAQ) About Garage Dehumidifiers
Q: How often should I empty the water bucket?
A: It depends on how humid it is. In very damp conditions, you might empty a small bucket every few hours. This is why continuous drainage is highly recommended for garages.
Q: Can I use a regular basement dehumidifier in my garage?
A: Maybe, but often no. Standard dehumidifiers stop working well when temperatures drop below 65°F. Garages get colder than basements, so you need a model rated for low temperatures.
Q: What is the ideal humidity level for a garage?
A: The ideal range is between 40% and 50% relative humidity (RH). This prevents rust on metal and keeps stored items from molding.
Q: Does a dehumidifier use a lot of electricity?
A: They use a fair amount, similar to a window air conditioner. Choosing an Energy Star model helps reduce this cost significantly.
Q: Do I need a special drain hose?
A: No, most units use a standard garden hose connection for continuous draining. Make sure the hose slopes downward away from the unit.
Q: What is the difference between a compressor and a desiccant dehumidifier for garages?
A: Compressor models work best in warm, humid air (above 60°F). Desiccant models work better in cooler temperatures but are often louder and less energy efficient.
Q: How long should I run my new garage dehumidifier?
A: Run it until the humidity level hits your target (40-50%). Then, let the humidistat maintain that level. It will cycle on and off automatically.
Q: Will a dehumidifier stop mold growth?
A: Yes. Mold needs high moisture to grow. By keeping the air dry, the dehumidifier actively prevents mold and mildew from forming on walls and stored items.
Q: How large of a unit do I need if my garage is attached but unheated?
A: Since it is unheated, you need a unit with good low-temperature operation. Measure your square footage and add 10-20% capacity just to be safe, especially if it stays damp.
Q: Can a dehumidifier remove odors from my garage?
A: While they dry the air, which reduces musty smells caused by moisture, they do not act as dedicated air purifiers. Dry air generally smells cleaner.
