Which type of dehumidifier is best?

The GE APER50LZ is not far behind. It has a slightly smaller tank than the Frigidaire FFAP5033W1, but it also has an active water pump. Its digital interface makes it easy to change settings. However, it is not as well ergonomically designed and it is more difficult to move or store it during the winter.

What put the Frigidaire FFAP5033W1 above the other devices we consider is its design. It is stylish and has an attractive digital display, making it easy to see indicator lights and settings. In the switch from FFAP7033T1 to FFAP5033W1, Frigidaire increased tank capacity from 13.1 pints to 16.9 pints. If you live in a very humid space and run the machine continuously, this is a significant improvement, because the volume of water will fill up quite quickly and the device will turn off until you empty the bucket.

The GE APER50LZ, our finalist, has a capacity of 15 pints. That said, the GE APER50LZ is an equal alternative to the Frigidaire FFAP7033T1 if you can find it at a better price. This dehumidifier is quite similar to our main selection, the Frigidaire FFAP5033W1, but it swaps Wi-Fi for an electric water pump. The unit comes with a drain hose to allow the tank to drain passively, or you can unload the 2 gallon bucket by hand.

Due to this recent change, many models are being discontinued and replaced with updated designs to accommodate the new procedure. For example, the GE APER70LW has been replaced by the almost identical GE APER50LZ. We will update these rankings as we learn more. In its tall configuration, the FFAP5033W1 reduced the humidity in our 135 square foot test space by 12% in one hour, from 59% to 47% (same as our best option), while battling a powerful humidifier that also worked high above, our approach to a challenging space, such as an unsealed cellar in the middle of a heavy rain.

At low temperature, with the humidifier also at a low temperature (approaching a less challenging space, such as a spare room or a closed porch that does not receive direct access from a home's HVAC system), it reduced humidity even further, by 15% in an hour. In overnight tests in a 3,100 square foot space, it completely filled its 16.9 pint (2.1 gallon) tank in less than 12 hours in height. Other types include desiccant dehumidifiers, which will use a water absorbing material, and thermoelectric dehumidifiers, which operate with charged plates. For a seamless experience that doesn't add extra stress to the task of dehumidifying your space, check out the LG PuriCare dehumidifier.

That's a change from the packaging of previous dehumidifiers, which claimed removal rates of 30, 50, or 70 pints per day. Since 65°F and 60% relative humidity is the new official test standard, what was once called a 70-pint dehumidifier is now called a 50-pint dehumidifier. Dehumidifiers for basement ventilation reduce the likelihood of mold and mildew growth, resulting in cleaner and safer air in your home. This Pro Breeze mini electric dehumidifier can remove about a pint of moisture from the air throughout the day and stores that moisture in a removable 3-pint capacity reservoir.

It is exceptionally well built: we have had many hours gaining hands-on experience with many different dehumidifiers. The Good Housekeeping Institute Media %26 Tech Lab regularly tests the performance, noise and efficiency of condensing dehumidifiers. We tested dehumidifiers in three categories based on their capacity, which is the declared measure of how much water each model can remove from the air. It also dehumidifies quickly: it doesn't dehumidify as fast as the Frigidaire FFAD5033W1, but it's still faster than average in its size class (50 pints).

The capacity of your dehumidifier's water tank will determine how often you should empty the unit. Mold that has already started to grow isn't necessarily removed with a dehumidifier, but a dehumidifier can help slow the spread of mold and prevent mold from starting to grow in the first place. This GE dehumidifier is a robust and economical alternative, but only for relatively compact spaces. We tested two LG dehumidifiers, the UD501KOJ5 equipped with pump and Wi-Fi and the similar UD501KOG5, which does not include.
