The quality of the air in your home matters. Air that’s too dry can cause sinus problems, although air that’s too moist comes with its own set of issues. Moisture problems can lead to mold and mildew, which have a larger effect on your overall health. You’ll find that produce and bread spoil quickly, your allergies and asthma may get worse, and even your pets can end up with health problems. In addition, your computers and other electronic devices can be damaged by the moisture in the air.
In order to alleviate the issues of air that’s far too moist, you’ll need a dehumidifier. These help you adjust the air to get it down to that ideal percentage of between 30 and 50% humidity. With that said, many dehumidifiers are large and noisy. They get in the way. That’s why we decided to look into the best small dehumidifiers.

What To Look For Before Purchase
Before you make a decision, there are several factors to consider.
Size & Weight
Since we are looking for a quality compact dehumidifier, size matters. The device should also be highly portable, so its weight plays an important role as well.
Most compact dehumidifiers are under 10 inches in height and usually weigh slightly over 2 pounds. In our comparison table you can check all the specific details for our top models.
Cover Area
Since the machines on our list are really small in size, you shouldn’t expect them to cover your entire house. Each dehumidifier has a suitable area set in square feet and cubic feet for easy comparison.
Operating Humidity
One of the most important factors to consider is operating humidity. It’s measured in relative humidity (RH), which is basically a ratio of the actual water vapor pressure to the saturation water vapor pressure at the prevailing temperature.
Water Tank Capacity
Tank capacity basically tells you for how long the device can operate before it needs to be emptied. Compact-sized dehumidifiers usually come with +- 20 oz water tanks. Depending on the usage and a specific model, the 20 oz water tanks will be filled in about 3 days. Considering how small these devices are, that’s not bad at all.
Moisture/Water Removal
Each model comes with an estimated number (in oz / ml) of water it can remove daily. On average, you are looking at about 10 oz (300 ml) of moisture removed daily. Again, this is pretty good considering the size of these devices.
Optimal Operating Temperature
Each device operates the best if recommended operating temperatures are met. Usually, you are looking at anything between 60°F and 86°F.
Noise
Noise level is yet another factor to consider. This is especially important if you plan on sleeping next to your humidifier. Thankfully, these small devices do not product any particularly disturbing noise. Most of these fellas generate around 30 decibels of noise, which is pretty acceptable for most people.
Budget
Of course, you should be able to afford your chosen device. I’d suggest checking the price first, so you won’t be disappointed later on.
