Dehumidifiers are very important for basements because they remove moisture from the air, which prevents the growth of mold, mildew, and dust mites.

They achieve this by sucking the air then passing it through cold coils to condense the moisture. This moisture is trapped and stored in a tank or drained via tubing, then the air is directed towards warm coils to bring it up to room temperature before releasing it.

That said, these appliances come in different varieties and sizes. This review covers the best dehumidifiers for basements to help you pick the one that suits your needs.

  • Size: 90-pint
  • Coverage Area: 2600 sq. ft.

With the capability of removing up to 90 pints (AHAM) of moisture from the air per day, AlorAir’s Sentinel HDi90 takes the overall best spot because it is very quick. Additionally, in saturated conditions (90% humidity and 90ºF), it can remove 198 pints per day, which is very impressive.

This is made possible by a Hot Gas Valve defrosting system (HGV), which is quick and efficient and can work at extremely low temperatures of up to 33.8ºF.

An epoxy powder coating is applied to the coils for internal corrosion protection, which makes the dehumidifier’s durability. It prevents hydroxide and sulfide compounds from eating into the metal, which would cause Freon leakage.

You also get a built-in heavy-duty condensate pump with a drain height of 14.7 ft., a remote-control option that is ideal for sound insulation and saving space, and a low sound pressure level of 58dB(A), which is equivalent to conversational speech.

The only problem is that the unit is very costly, but it is worth the price.

Pros:

  • High 90 PPD moisture removal
  • Efficient Hot Gas Valve defrosting system
  • Epoxy powder coating for corrosion protection
  • Built-in pump with a drain height of 14.7 ft.
  • Remote control option

Cons:

  • Expensive

  • Size: 1.6-pint
  • Coverage Area: 269 sq. ft.
  • Tank Capacity: 0.5 gal

For those looking to buy an affordable dehumidifier that is also reliable and highly efficient, Honati’s B07WWFRG5R is the ideal choice to spend on. Though it has a small 0.5-gal tank, the unit is equipped with an automatic shut-off feature that prevents overflowing once full.

Apart from that, the product is powered by advanced technology without a compressor, which makes it run very quietly. It produces noise that is below 60 dB and this creates a quiet environment in your bedroom, baby room, RV, or basement.

Other features are a detachable and easy-to-clean filter, and easy one-button operation. On the downside, the unit can only remove 750 ml (1.6 pints) of moisture per day at 86ºF and 80% humidity. This makes it ideal for a small 100-269 sq. ft. space.

Pros:

  • Affordable
  • Automatic shut-off
  • No-compressor design for quiet running
  • Easy one-button operation
  • Easy-to-clean filter

Cons:

  • Small tank
  • Low rate of moisture removal

  • Size: 70-pint
  • Coverage Area: 3800 sq. ft.

Aprilaire’s 1830 is rated at 70 pints of moisture removal per day in a large 3800 sq. ft. area, which is ideal for commercial use in basements and crawl spaces. It can also be used domestically for the whole house because it packs in quite a lot of power.

The humidifier is fitted with corrosion-resistant aluminum coils that prevent the refrigerant from leaking due to wear and tear. This enhances its durability for long-lasting use.

Aside from that, the unit does have a water tray for collecting the condensed water. It relies on a continuous drainage system, which requires you to hook it up to a hose to direct water outside to the drains.

This design makes the model fully automatic because you don’t have to empty the tray every once in a while.

Other features include leveling feet and inlet/outlet collars for connecting to air ducts for targeted dehumidification.

However, the product is quite expensive and it lacks a built-in pump for draining to a height above its placement.

Pros:

  • Large 70-pint size and 3800 sq. ft. coverage
  • Corrosion-resistant aluminum coils
  • Easy-to-use continuous drainage system
  • Includes inlet and outlet collars

Cons:

  • Expensive
  • Lacks a pump

  • Tank Capacity: 1.3 gal

With a power rating of 6.9 Amps/ 720W, Ivation’s IVALDH70PW is quite energy-efficient. It is also energy star certified, which means it is tested and found to be eco-efficient.

That said, the unit still offers impressive performance because it can remove 50 pints of moisture from the air per day. It was rated at 70 PPD in the old 2012 DOE standards, which was measured at 80ºF and 60% humidity.

The appliance is very easy-to-use because it has a plug-n-play design and requires very low maintenance. Additionally, it has a digital control panel with a bright LED display for adjusting the fan speed, timer, filter alert, and many other settings.

You also get a frost sensor, a washable air filter, a removable 1.3-gallon tank, and a hose hook up for continuous drainage. However, the drainage hose is not included in the set. 

Pros:

  • Coverage Area: 4500 sq. ft.
  • Tank Capacity: 1.8 gal

Vremi’s 52140000 packs in a memory function that stores all the settings in case of a power outage. As such, when the power supply is restored, the unit picks up from where it left off, which is very convenient.

It has 2 other key convenience features, which are auto shut-off that pauses the condensation process once the 1.8-gallon tank is full and auto defrost, which prevents the coils from freezing.

That said, the water tank has a narrow transparent strip that shows the water level at a glance and there is the more convenient option of continuous draining using a hose. However, the dehumidifier does not have an internal pump and the hose is not included.

Other features include a removable, washable filter and handles for easy portability.

How to Buy the Best Dehumidifiers for Basement

How to Buy the Best Dehumidifiers for Basement

1. Coverage Area

Given in square feet, this is the approximate area that the dehumidifier can serve. Generally, you need a unit that removes at least 25 PPD (Pints Per Day) for a space that is about 2000 sq. ft.

However, this is not standardized because some of these appliances have a high PPD value but the coverage is quite small. For instance, AlorAir’s Sentinel HDi90 can remove 90 PPD but has a coverage area of 2600 sq. ft.

It can handle a much larger area than this and therefore, it does have a slight edge over the others.

2. Standards

Another important factor to consider is the standard used to determine the PPD. Most dehumidifiers use the new 2019 DOE (Department of Energy) standard, in which the units are tested under two conditions: 65ºF room temperature and 60% relative humidity.

This classifies them mostly as 30, 50, and 70 PPD humidifiers. Before this, there was the 2012 DOE standard, which was based on a room temperature of 80ºF and 60% relative humidity.

There is also the AHAM rating (Association of Home Appliance Manufacturers), which rates the PPD based on similar conditions as the old 2012 DOE standard, which is 80ºF and 60% relative humidity.

On the other hand, the saturation rating is based on 90ºF and 90% relative humidity, which represents very extreme conditions. Some units even have customized standard ratings based on different temperature and humidity conditions.

All in all, it can be really difficult to compare the products if they are based on different ratings. Therefore, you should consider buying dehumidifiers with either one of the three ratings (AHAM, 2012, or 2019 DOE) because these are trusted.

3. Drainage Options

There are two drainage options and the most common one is a water tank. This needs to be emptied once full and therefore, it is more convenient to have a larger tank because this means less frequent emptying cycles.

Continuous draining is more convenient because you don’t need to empty the tank every once in a while. Instead, a hose directs the condensed water outside or into the drains.

Some units have an internal pump to push the water over a vertical length and this is recommended for basements if you want to empty the water outside. For this, be sure to check out the Tosot GDN45BA-A3EBA2B.

4. Noise Level

Dehumidifiers are not restricted to basement use where noise is not a big issue. Within the main house and especially in bedrooms, if it is too noisy, it might interrupt your sleep, and therefore, the quieter it is, the better.

That said, noise is measured in decibels and the lower it is, the better. For example, Inofia’s GA2 runs while producing less than 46 dB in noise. This is almost equivalent to the sound produced by moderate rainfall, which is silent enough for home use.

5. Extra Features

There are several convenience features that you should look for and the main one is auto-humidistat.

This is quite common and it automates the moisture removal process by starting the condensation process when the humidity level goes above the set threshold. It then stops the process once the level is below the threshold.

Another important one is auto-defrost and this helps to protect the coils from freezing when the room temperature is very low. More includes a memory function and multiple fan speed settings.

6. Maintenance

Lastly, you need to check the maintenance process of the dehumidifier and the ideal one should have an easily removable and washable air filter.

Conclusion

In conclusion, AlorAir’s Sentinel HDi90 takes the overall best dehumidifier for basements slot because it has a high moisture removal rate of 90 PPD, an efficient defrosting system, and an internal pump for vertical length draining.

On the other hand, Aprilaire’s 1830 has a wider coverage area rating of 3800 sq. ft. plus a relatively high removal rate of 70 PPD and inlet/outlet collars, which make it suitable for commercial use.

These two are quite expensive though. If you are looking for an affordable high-quality dehumidifier, check out the Honati B07WWFRG5R.
