Tight on budget but need to tame the humidity monster in your garage? This is one of the less pricey models you could find. It’s a gem for those who need to address occasional dampness or prevent minor moisture problems. It can cover up to 480 square feet, so it will work for single-car garages petty well.

  • Tank Size: The small tank requires regular emptying, which can be inconvenient.
  • Noise: Some users report noise levels being higher than desired.

Think Twice:

  • Those with serious moisture problems: With a dehumidification rate of only 2 pints per day, this won’t tackle major dampness or large spaces.
  • Those seeking quiet operation: Some users find the Gocheer to be noisier than other models.
  • People who want continuous operation: The water tank fills up quickly, requiring frequent emptying.

What Should The Humidity Be In A Garage?

Aim for a sweet spot between 30-50% humidity. This range discourages mold growth, protects belongings from moisture damage, and keeps the air breathable. Exceeding 55% humidity raises red flags, signaling potential moisture problems.

What Humidity Is Too High For Garage?

Anything above 55% is considered dangerous territory. This high humidity creates a breeding ground for mold, attracts unwanted pests, and can even damage stored items like cardboard boxes and wooden furniture.

Is It Worth Putting A Dehumidifier In A Garage?

Absolutely! If you live in a humid climate or store moisture-sensitive items, a dehumidifier can be your garage’s best friend. Think about what you keep in your garage:

  • Classic car or motorcycle: Maintaining a consistent, low-humidity environment is crucial for protecting your prized vehicle from rust and mold growth.
  • Musical instruments: These can be damaged by excess moisture, affecting their sound and playability.
  • Tools and equipment: From power tools to gardening equipment, keeping them rust-free ensures they’re always ready for action.
  • Seasonal decorations and clothing: Mold and mildew can wreak havoc on stored items like holiday ornaments or out-of-season clothing.

How Long Does A Dehumidifier Take To Dry A Room?

It depends on three main factors:

  • Garage size: Bigger garages take longer.
  • Humidity level: Super humid garages need more “dehumidifying therapy.”
  • Water damage extent: Major leaks mean more drying time.

Generally, expect 24-72 hours for it to work its magic, but this can vary. Remember, consistency is important! Keep it running continuously until the desired humidity level is reached.

Is It OK To Leave A Dehumidifier On All Day?

Most modern dehumidifiers have auto-shutoff features that turn them off when the desired humidity is reached.

However, leaving it on continuously won’t harm it, as long as the water tank is emptied regularly. It’s just inefficient and unnecessary. Consult your specific model’s instructions for optimal usage.

Where Should A Dehumidifier Be Placed In A Garage?

Choose a central location with good air circulation, away from walls and heat sources. Place it on a level surface and ensure the drain hose is properly positioned.

Remember, proper ventilation is also key to controlling garage humidity. Open garage doors regularly or invest in exhaust fans to promote airflow and prevent moisture buildup.

Should A Dehumidifier Be On the Floor?

While not strictly necessary, placing it slightly off the ground has several advantages:

  • Better air circulation: This allows the dehumidifier to draw in more air from all sides, improving its efficiency.
  • Reduced dust and dirt: Keeping it off the floor minimizes its exposure to dust and dirt, prolonging its lifespan and reducing maintenance needs.

However, the floor restricts airflow and exposes it to dust and dirt. Opt for the 6-12 inch elevation mentioned above for optimal performance.

Do Dehumidifiers Use A Lot Of Electricity?

While energy consumption varies based on models and settings, modern dehumidifiers are generally energy-friendly.

Look for models with Energy Star certification to maximize savings. Remember, preventing moisture problems in the first place can be more energy-efficient than constantly battling them with a dehumidifier.

Will A Dehumidifier Stop Mould In Garage?

Think of a dehumidifier as a preventative shield against mold, not a magic eraser.

If you already have mold, tackle the source of the moisture first (leaky pipes, poor ventilation) and clean the mold itself before relying on a dehumidifier to maintain a healthy environment.

Is It Ok To Use A Dehumidifier In Winter?

Yes, with some considerations. Most of them work effectively down to temperatures around 40F (4C). However, performance can decrease below this point.

Where Should You Not Use A Dehumidifier?

These work best in controlled environments. Avoid using them in:

  • Uninsulated spaces: In uninsulated garages, the dehumidifier will constantly battle against the outside humidity, making it less effective and energy-hungry.
  • Rooms with open flames or flammable materials: Dehumidifiers can create sparks, so keep them away from anything flammable for safety reasons.
