Too much moisture and humidity in your home can cause a range of issues. Everything from your sleep to your productivity and energy levels can be affected. Prolonged exposure to compromised air quality may also cause health problems such as coughing, sneezing, and an increase in allergy symptoms.
One of the major warning signs that your home is too humid is patches of mold and mildew on walls and even on furniture. However, it isn’t only what you can see which suggests you have a problem as there may also be an unpleasant, musty odor in your home as well. Thankfully, investing in a dehumidifier can help to resolve these issues and ensure that you and your family breathe more easily.
If the humidity in your home is causing these problems, you may want to look into purchasing a 30-pint dehumidifier. These are big enough to take care of moisture in singular rooms but small enough to be able to move from room to room.
When picking out our top choices we looked at weight and budget alongside distinctive features such as:
- An indicator that enables you to monitor water levels in the tank
- Wi-Fi compatibility so you can operate it from your smartphone
- Visual reminders that you need to clean reusable features
Room size is a crucial factor when choosing a dehumidifier. The Airplus 30 Pints Dehumidifier is great for small areas and covers 500 square feet. But the TECCPO 3,000 Sq. Ft. Dehumidifier is ideal for larger spaces.
To ensure we found the best 30-pint dehumidifiers, we used consumer reports analysis to remove any false reviews. All our recommendations came from genuine people like you who have previously used and can vouch for these units.

1. Honeywell TP30AWKN Smart Wi-Fi Dehumidifier
Honeywell is one of the most notable brands for comfort and safety appliances for the home, and this dehumidifier will certainly exceed your expectations. The Honeywell 30-pint dehumidifier is a stylish and efficient addition for small spaces. It integrates seamlessly with your smart connected devices through the internal 2.5 GHz Wi-Fi.
The built-in digital humidistat allows the unit to run independently while maintaining the desired humidity level. It also removes airborne contaminants through the washable mesh filter, making it perfect for removing moisture-driven contaminants.
The smart features allow the app to automatically engage the unit based on the outdoor humidity conditions. The app automatically monitors the outdoor humidity and activates the unit when conditions you set are met.
You’ll be able to easily move the unit with the built-in casters on the bottom. It has a built-in handle that can withstand up to 150 lbs, which is well over the weight of the unit. This makes it easy to move the unit around and get it close to the moisture source in a damp environment.
Both the filter and water reservoir have indicators on the control panel and in the app to alert you they need your attention. If the tank fills, there’s an auto-shutoff feature to prevent the reservoir from overflowing. When you do empty it out, there are splash guards on the reservoir to prevent accidental spillage. If you prefer not to worry about the internal tank, it comes with a drain line for continuous draining.

We don't like this as much
- The dehumidifier is quite powerful, so if you don’t have a drain nearby, you’ll have to empty the tank frequently throughout the day
- The humidistat only registers in increments of 5 percent, so there’s a 10 percent range between when it shuts off and when it starts again
2. Vacplus 1,500 Sq Ft Dehumidifier
The Vacplus dehumidifier brings together a compact design with efficient moisture mitigation. It offers both an internal storage tank for easy mobility and a continuous drain option to allow it to run without constant surveillance.
The Intelligent Constant Humidity Control allows you to set your target relative humidity. You can also set a 24-hour timer for both starting and shutting down the unit. This allows you to better control when the unit will run, targeting high-humidity parts of the day, or lower energy cost times, depending on your individual preferences and goals.
The simple controls allow you to easily set the unit for what you need. There are two speeds to control how much air moves through the unit. The modes include a drying setting to help dry damp clothes and towels and then automatically shut down.
Convenience features include an automatic restart after a power outage or when you empty the water reservoir. You don’t need to try to remember the settings to get it back up and running when it shuts down for one of these reasons.
This unit is also easy to tuck away, measuring in at 11.3 x 6.7 inches, and standing only 19.7 inches tall. It is lightweight and has rollers on the bottom to allow you to easily move it around your room as needed. The small footprint means you can easily set it on a countertop or reinforced shelf to make using the continuous drain easier.

The Ivation Energy Star Dehumidifier is perfect for small to medium-size spaces, effectively dehumidifying up to 2,000 sq. ft. This particular model boasts an incredibly large 1.3 gallon reservoir, meaning you don’t have to worry about constantly emptying it to keep it running. There’s even a window on the reservoir for you to easily observe the water level.
If you plan to be away from the unit for an extended period, there’s a continuous drain to connect any standard garden hose. Using your own hose ensures you have the right length to run to your drain, even if the unit isn’t right next to it.
The Ivation comes with automatic defrost, ensuring you don’t waste energy or damage your unit with frozen coils. There’s also an auto-shutoff sensor if the water reservoir fills, preventing damage from an overflowing unit. This model offers automatic humidity control, two different fan speeds, and a 24-hour timer for easy control.
Controlling the unit is exquisitely simple, with only a few buttons. You can turn on the continuous function with a single touch, or adjust your fan speed and humidity level to your liking. There is an indicator when the filter needs cleaning, and a button to reset that sensor. If the unit loses power, it has an auto-restart feature, which restores the setting before losing power.
The profile measures 14.2 x 9.9 x 20.1 inches to accommodate the larger capacity reservoir. It has casters under the unit, and molded handles on the side to assist in moving it around.
- Moisture Removed: 30 Pints
- Room Size Suitability: 2,000 sq. ft

We don't like this as much
- The unit does not come with a hose, so this will need to be purchased separately if you want to use the continuous drain feature
- It runs more a little more loudly than other models, meaning it is not as ideal for bedroom use at night
4. AIRPLUS 30 Pints Dehumidifier
The AIRPLUS brings style to the technical aspect of controlling moisture in your environment.

6. Yaufey Dehumidifier
Yaufey may not be a name you’re familiar with within household appliances, but that doesn’t stop it from being one of the top-rated compact dehumidifiers. Despite its small 11.4 x 7.1 x 17.3 inch profile, it is quite capable of handling spaces up to 1,750 sq. ft.
The sleek design is matched by the low 26.7 lbs weight, making it easy to maneuver, set up, and a breeze to fit into small spaces. The base is outfitted with rotatable wheels to assist with placement, along with a molded handle above the filter on the rear of the unit.

If you’re looking for a compact dehumidifier that really packs a punch, look no further than the TECCPO 30 pint dehumidifier.

Frequently Asked Questions
What size room can a 30 pint dehumidifier cover?
Several factors determine how much space a 30 pint dehumidifier will effectively cover. The biggest factor is the amount of moisture in the room. In a moderately damp room, you can cover anywhere from 500-1,500 square feet. If your room is very damp, it drops to between 500-1,000 square feet. If you have an extremely wet room, such as after a flood or in a bathroom, it’ll effectively cover about 500 square feet.
In addition to dampness, you also have to look at what other factors may contribute to additional moisture. Is there a washer and dryer near the room? Does more than one person typically spend time in the room? Are there large or multiple windows in the room? Finally, what is the outdoor humidity in your climate? All of these factors may decrease the serviceable area for any particular dehumidifier.
How often should you empty a dehumidifier?
You can get away without emptying your dehumidifier at all if you set it up with the continuous drain feature. However, most bedrooms do not have a floor drain close by, so you will need to keep an eye on the condensate reservoir.
How often you have to empty it will depend on the amount of moisture in the air and the size of the reservoir. Many 30 pint models have relatively small reservoirs, usually about 1-1.5L. However, some models have larger reservoirs of over 1 gallon, making for less frequent emptying.
Furthermore, the mode you use will change the frequency of moisture collection. If you’re running on Continuous mode, you’ll have to empty the reservoir more often than if you use one of the automatic settings.
When you first start out, plan to check your unit every few hours to see how quickly it’s filling. Once you’ve run it for a few days, you’ll get a sense of the frequency, likely once or twice a day.
What is the average lifespan of a dehumidifier?
Like any other refrigeration system, your dehumidifier will eventually wear out and need replacing. Most units have an average lifespan of anywhere between 5 and 10 years with proper maintenance.
Be sure to clean the air filter regularly to ensure it can move air effectively and reduce strain on the system. You’ll also want to clean the condensing coils and exhaust grills regularly to prevent airflow restrictions.
Which Dehumidifier is best for you?
Humidity is a major factor in controlling your indoor air quality and the general health of your living space. The EPA recommends keeping your relative humidity between 30% and 50%. Moisture greater than 50% encourages bacterial, fungal, and mold growth. Not only is this gross, but it also destroys furniture and wreaks havoc on your health. Air with less than 30% relative humidity increases dust and airborne contaminants by drying out your skin and furniture. Those airborne contaminants stay afloat longer, leading to greater respiratory irritation, and more strain on your HVAC system. Keeping your humidity properly controlled is important for both your home and your health.
The dehumidifiers we have listed above are all regarded highly for their efficient operation, however, you may decide to opt for a system that has smart features, such as the Honeywell Smart Wi-Fi Energy Star Dehumidifier. Take into consideration the size of the area you are looking to cover, as well as factors including portability, the size of the unit, and the type of room you will be placing the unit in.
