Features to Look for if You Want to Buy
A person may feel overwhelmed when selecting the best dehumidifier, given the dozens of models with varying features. But with a careful assessment of the features, shopping can be more comfortable.
When purchasing the best garage dehumidifier, you should take into account its extraction rate, the size of the room, and its effectiveness in lower temperatures, energy consumption, and noise levels. Let’s highlight some of those aspects below.
Pints are a great way to measure the performance of dehumidifiers. You might find versions with 30 pints, 40 pints, 50 pints, and 70 pints. These reflect the amount of moisture the model can extract in 24 hours.
It is important to consider these points when choosing a particular footage area. If you select a small model for a larger room, its efficacy may not be ideal. Likewise, selecting a larger model for a smaller area might cause too much heat in the room or waste too much energy.
I recommend 30 pints for small rooms and 70 pints for larger garages. The prices will vary according to the capacity.
The other consideration is the drainage capability of the dehumidifier. Many units have automatic shut-off features to indicate that it needs emptying. This feature could be inconvenient for some.
What if you had to spend a weekend in the wilderness? You wouldn’t stay home to empty the tank. Meanwhile, moisture will accumulate and damage your equipment and belongings.
Garage dehumidifiers have continuous drainage functions with the addition of a hose. Some come with a hose, while others do not.
This feature is important because it will help you set your preferred humidity in the garage. You can have an acceptable level of moisture in your room. The humidistat can automatically turn off if that preset level is reached. This feature helps you save energy.
Although the garage is seldom used as a living room, it is still important to consider the noise levels of these humidifiers. Some noise levels can be annoying. Manufacturers often use decibels as an indication of the efficiency of the unit in terms of noise levels. Desiccant dehumidifiers are less noisy compared to compressor dehumidifiers.
A larger dehumidifier in a small room can sound noisier. The higher the pint size, the noisier it gets. But that’s not always the case from one manufacturer to another, as different factors can account for the difference.
You need a portable model if you intend to use the dehumidifier in several rooms. Pay close attention to the overall weight. Check to see if the unit is versatile enough for use in all rooms within the reasonable square footage.
A garage is less insulated and needs a more high-performance model than other rooms. Some units have handles and wheels to move them with ease. In addition to these features, here are some helpful tips regarding dehumidifier use in your garage.
What Size Dehumidifier do I Need for My Garage?
The size of the dehumidifier refers to its capacity. It’s important to calculate your home’s size before buying one. A 30-pint unit is adequate for square footage up to 1,500.
A 50-pint unit is suitable for garages over 1,500 square feet, while a 70-pint unit is for rooms over 2,500 square feet. The extent of the dampness also plays a role in the choice of size. Some climates have much higher humidity than others.
Heater or Dehumidifier
Homeowners sometimes need clarification about buying a dehumidifier or a heater for their garage. A heater can help warm the room and reduce dampness. However, it is less effective than a dehumidifier.
A dehumidifier extracts moisture to its coils, where it condenses it. The liquid is then emptied. At the same time, dry air is released into the room and warms it. A heater does not function this way. It can be costly to heat a garage, considering its insufficient insulation compared to the rest of the house.
Here’s a quick glimpse into the dehumidifier for your garage. This YouTube video explains what to look for when shopping for the best garage dehumidifier.
All these units are impressive, but the price can be a deal-breaker for some units. However, as highlighted under essential features to consider before buying, it is crucial to evaluate each unit according to your needs.
They differ in capacity, and each is ideal for a specific square footage room. My pick goes to the Vremi (70 Pint) Dehumidifier. Moreover, they often have high humidity levels because of insufficient insulation compared to the rest of the house. So, a powerful garage dehumidifier like this unit is preferable.
