What I like

If you’re tired of monitoring your dehumidifier, you won’t have to deal with that any longer with the effortless humidity control. It will sense your environment’s humidity level and turn the unit off and on, making this unit more energy efficient over other units.

This model also has a unique drying clothes mode. If it’s raining outside but you need to get rid of the excess moisture in your clothes ASAP, it will dry your clothes without causing condensation like a radiator would.

The sleek aesthetic of this 30 pint dehumidifier is nice, fitting into the decor of any home. You’ll be able to reach your desired humidity levels in style. With an average decibel level of 36dB, you’ll be able to enjoy continuous operation without any disturbances.

You also get a timer function, time down function, 24-hour timer and adjustable fan speed. The continuous drainage option will allow you to dehumidify any space without the fuss of emptying out the water tank.

What I don’t like

This unit does not come with auto defrost feature which can be an issue if you live in colder climates. It also doesn’t have an auto-restart function if there is a power outage which is a minor inconvenience.

The small tank is also going to be inconvenient if you’re using this dehumidifier in continuous operation as you’ll need to change it often.

Why I’m recommending this product

Compared to the Inofia 30 Pint Dehumidifier, this unit has a much better aesthetic, casters on the bottom, and a year longer warranty. While the tank is a bit smaller, it does offer quiet operation and improved efficiency with its rapid condensation absorption. It also costs a bit less as well!

If you’re ok setting up a continuous drain with this dehumidifier, then I’d go with this option. If you’re setting up a 30 pint dehumidifier in your basement, then you’d need the auto-defrost function that the Inofia 30 Pint Dehumidifier offers.

  • Intelligent humidity control
  • 2 year warranty
  • Sleek aesthetic
  • No auto defrost
  • No auto restart
  • Tank is on the small side

If you need to control the humidity level in a room and don’t want to fiddle with a garden hose or continuous drainage, you’ll be able to enjoy removing excess moisture all year round. The bigger tank will make it so you don’t have to empty it out as often.

It also has an auto-defrost function which makes it great for controlling any musty odor or excess moisture in a basement or any other room that requires low temperature operation.

If you’re wanting a more portable dehumidifier, then I would suggest the Vacplus 1,500 Sq. Ft. Dehumidifier over this unit.

What I like

What stands out about this unit is that it has an incredible half gallon tank. Compared to the AIRPLUS 30 Pints, that’s twice as much capacity! With less need to empty your water tank, you’ll have an easier time using this 30 pint dehumidifier.

It’s feature rich too, with digital controls, a washable filter, real time intelligent humidity level control, auto defrost function and 24 hour timers. The recessed handles and 360 caster wheels make it super easy to move this unit around as well.

The full tank indicator will let you know exactly when you need to empty the tank. Once you’ve reached your desired humidity level, it will turn itself off. The LED display is futuristic, showing you the humidity levels in the room. You can also enjoy from multiple fan speeds adjusting to your preference.

You can opt to use the direct drain system or continuous draining, whatever you prefer. This unit also has 360 degree airflow, allowing this unit to dehumidify in all directions. The quiet fan makes this unit ideal for bedrooms.

What I don’t like

Sadly this unit is not energy star certified. Reviewers also suggest that the drainage hose included in this system was not the greatest and recommended purchasing a new one from a local hardware store.

Why I’m recommending this product

Compared to more expensive 30 pint dehumidifiers, this unit stood out amongst the competition. It has all the features you’d ever want and more, as well as employing an auto defrost function for usage in basements. It’ll be great in medium sized rooms and the intelligent humidity control will allow for better power consumption.

You also get to enjoy a 2 year warranty, which is much more than the AIRPLUS 30 Pints. If this unit had a better aesthetic look, it may have been a contender for best 30 pint dehumidifier!

What I like

With its budget cost, you’ll still be able to control the humidity level in a 1500 square foot space. If you’re dealing with too much moisture causing musty odors, structural damage and mold, you won’t have to deal with that any longer.

The electronic controls on this 30 pint dehumidifier give you 4 modes, continuous operation, standard, drying, raining/sleep mode for quiet operation. You’ll be able to adjust the humidity levels from 40-80% on continuous operation mode.

If you want this unit to shut off while you sleep, the timer button allows you to do that! You can also set it turn on when you come home, giving you protection when you need it. You can decide to use manual drainage or continuous draining, whatever your preference. If you do use the water tank, the front panel will show you when its time to empty the tank.

This 30 pint dehumidifier has a washable filter that is easily accessible on the side. The caster wheels on the bottom move in 360 degrees, so you won’t have any issue moving this unit from room to room.

What I don’t like

The warranty on this unit is only 30 days, which is not going to be ideal for the long term. Some reviewers mention that they had issues using the continuous drainage because of a design flaw which makes this less attractive of an option.

Why I’m recommending this product

If you want to improve the air quality in your home, prevent dust mites, mold, and mildew, all while enjoying a budget price, this 30 pint dehumidifier is what you’re after. It still has plenty of features like a washable air filter, compact design and caster wheels making this a portable dehumidifier.

Sadly, the warranty is quite short, so do keep that in mind. This unit also isn’t going to be suitable for low temperature operation as it doesn’t offer auto defrost. If you’re wanting to control the humidity level in a basement, then check out this Inofia 30 Pint Dehumidifier option instead.

While this isn’t a 30 pint dehumidifier, you do get a whopping 1.18 gallon water tank that makes it less fussy to use, as well as a 70 pint capacity.

What I like

A 30 pint dehumidifier may not be enough for the amount pints of moisture daily you’ll need to remove from the air. That’s why you should consider getting a 70 pint capacity unit so you can enjoy from top quality moisture removal.

The intelligent humidity control will make it easy to know what the humidity levels are in your space as well as control the unit by sensing the humidity in the air. You will save money with its efficient performance by only activating this unit when the humidity sensor reaches its level.

The water tank is also twice as large as even the biggest 30 pint dehumidifier on this list. It also has a transparent water level indicator which makes it easy to know when you need to empty the water tank. It also operates at a low noise level of 46dB on and 40dB on the high and low fan speeds.

One feature other dehumidifiers on this list lack is a child lock setting. This dehumidifier will allow you to keep your children from changing any settings while you’re away. While this isn’t the best 30 pint dehumidifier, it is a great choice for best dehumidifier overall.

What I don’t like

This unit isn’t energy star certified, but I’ve found that most other units I’ve reviewed aren’t but it doesn’t have to be a deal breaker.

Why I’m recommending this product

I think that if you’re working with excessive moisture and need to run a dehumidifier continuously, this 70 pint dehumidifier is for you. I enjoy that it can control excess humidity, has a digital humidity display and has a much larger water reservoir than other units. The sleek aesthetic is a nice touch, too!

You can enjoy the continuous drain option or simply use the tank as you wish. Compared to the recommended Vacplus 1,500 30 pint dehumidifier, this unit offers a much bigger capacity and doesn’t cost that much more.

  • 70 pint per day
  • 1.18 gallon tank
  • 2 year warranty
  • More expensive than a 30 pint dehumidifier
  • Not energy star certified
  • Might be too large for your needs

What to consider when purchasing a 30 pint dehumidifier?


Warranty is important to consider when purchasing the best 30 pint dehumidifier. If anything goes wrong, then you’ll want the guarantee that you’ll be able to service your dehumidifier. Otherwise, you’ll be taking a risk that your unit may fail in a year’s time.

Water tank capacity

If you are in an extra humid environment, then you’re going to want a big water tank. Consider that a 30 pint dehumidifier does not have a 30 pint tank, it is only rated to remove 30 pints of excess moisture per day. The tank is normally quite a bit smaller, from 2 to 5 pints.

If you don’t want to worry about emptying out a tank every day or so, then it’s important you find a model that offers continuous drainage.

Auto defrost

Do you live in a cold environment? If so, auto defrost is going to be vital to your dehumidifier’s capability. If the coils freeze over and you don’t have a defrost feature, you won’t be able to use your 30 pint dehumidifier at all! Some units do have this feature, but some don’t, so do double check when purchasing.


Are you going to put your dehumidifier in one spot and not move it ever again? If you’re considering moving it from room to room, then you’ll want a dehumidifier with handles on the side as well as caster wheels. That way, you won’t have a big, heavy block full of water to lug around your place. Simply roll it around and place it where you need it.

Continuous drainage

If you’re lazy like me, you’re not going to want to remove a water tank every day (or even more depending on the place you’re dehumidifying). Continuous drainage will allow you to hook up a drain hose and not worry about changing out a water tank or getting wet.

Noise level

If you’re placing your unit in a bedroom, it’s important that it won’t keep you awake. Aim for a decibel level under 45 so you won’t have to deal with any background noise at night. Most dehumidifiers on this list allow you to chose from multiple fan speeds, which will help lower the noise regardless.

How to maintain a 30 pint dehumidifier?

To maintain your 30 pint dehumidifier, you’ll need to keep an eye on the water tank indicator light and change out the tank when it’s full. You’ll also want to clean the filter each month so you can enjoy improved air quality all year round.

How to buy the right sized dehumidifier?

First, you’ll need to measure the size of your room. Then, I’d recommend buying a unit that’s going to service an area larger than your space. This is because manufacturers over-estimate the performance of their products by testing in optimal conditions. You won’t be in optimal conditions, so your dehumidifier won’t work as well. If you have an extra humid room, then add on 10 pints to your estimate.

You can measure the humidity levels in your home if you’re wanting to know how humid it actually is rather than guessing. You can also guesstimate as well, if it’s a really damp room and large room, you’ll need a 70 pint dehumidifier. If it’s a damp room of 500-1500 square feet, you should be ok with a 30 pint dehumidifier.

Final Thoughts

With its sleek performance, 2-year warranty, and intelligent humidity control levels, the best 30 pint dehumidifier I could find was the Vacplus 1,500 Sq. Ft. Dehumidifier. If you’re needing one for a basement, then I’d recommend the Inofia 30 Pint Dehumidifier instead with its auto defrost functions.
