A warm and humid environment provides a thriving breeding ground for mold spores and mildew. That is why bathrooms and basements seem to be the most affected. Mold causes hypersensitive reactions, such as wheezing, fever, shortness of breath, and itchy eyes and skin, and aggravates other respiratory infections like asthma. This review looks at the best dehumidifier for mold which can effectively reduce excess moisture from the air and restore optimal humidity levels.
We focused on the key features to consider when looking for the right dehumidifier. The dehumidification performance is obviously a prominent factor because you need a model that actually works. Next is the coverage area to match it with the space you intend to reduce excess moisture, and the dimensions and weight to ensure the unit fits in that space. Both the tank capacity and the continuous drain option matter because they extend the runtime and reduce or eliminate the need for frequent emptying. Other features we evaluated were the noise level for a quiet operation and the warrant for mitigation against any future malfunctions and damage. Based on these, our Editor’s Choice goes to the Vremi 22-Pint Dehumidifier .

Next is the Vremi 22-Pint Dehumidifier with coverage for medium to relatively large rooms. This option is efficient enough to eliminate 22 pints of moisture in the air per day and even manages to be energy star certified while doing so. As such, we noticed it doesn’t use up much energy.
The outlook of the Vremi is sleek and will probably look stylish in many room settings. Also, it doesn’t need to be installed in one room in the house. It comes with wheels and convenient handles so you can put it in whichever room needs it the most.
Additionally, the water tank in this option has a capacity of slightly over 100 oz. This is likely to fill up relatively quickly and, as a result, will need frequent emptying. The dehumidifier even turns off automatically whenever the tank is full.
However, you can also opt for the continuous drain option available in the machine if you’d much rather avoid the hassle. That said, the drainpipe is not a part of the initial purchase and will have to be bought separately.
Users can pick their most ideal moisture settings before leaving the device to work independently. Additionally, the device comes with a relatively quiet fan. However, there is an extra turbo mode that increases moisture removal and the machine’s efficiency by increasing fan speed.

If you have a large room or plenty of humidity, then this would be the best dehumidifier for your bathroom, basement, and mold. It is equipped with a large tank that can hold up to 210 ounces of the drawn moisture and a full tank alert to notify you when it is due for emptying, and in case there is a lot of moisture which will need constant emptying, the continuous drainage option comes handy.

Generally, mini dehumidifiers are designed to remove excess moisture in small spaces like cabinets, wardrobes, closets, bedrooms, nurseries, small bathrooms, or in a car. This is why most of them do not offer the continuous drainage option since the tank will not fill up with moisture quickly. The water tank in this model has a capacity of 23.7 ounces. An LED indicator light turns red when the tank is full, and the dehumidifier shuts off automatically to prevent water from overflowing.
You can opt between two modes, normal and sleep, depending on your humidity needs and the level of quietness you prefer. Since this model uses Peltier technology which does not consist of a compressor, it runs quietly on both settings, producing only 35 decibels on sleep mode. The lack of a compressor also makes it compact and light enough – it weighs a negligible 1.2 pounds – to install on a nightstand, under closet shelves, or virtually any tight spaces.
In addition to preventing mold, the highly rated dehumidifier also eliminates musty odor using a patented Energy Recycle System technology.

According to the Centers for Disease Control and Prevention (CDC) Trusted Source Facts about Stachybotrys chartarum - CDC Stachybotrys chartarum and other molds may cause health symptoms that are nonspecific. It is not necessary to determine what type of mold you may have growing in your home or other building. All molds should be treated the same with respect to potential health risks and removal. www.cdc.gov , exposure to mold can cause hypersensitive reactions like wheezing stuffy nose, wheezing, and red or itchy eyes, or skin, or severe reactions like fever and shortness of breath. It may also lead to the development of asthma.
Other issues include headaches, nosebleeds, memory problems, and mood swings.
California Department of Public Health Trusted Source Mold and Dampness - CDPH We know that dampness and mold cause health effects both in allergic and non-allergic people. If you can see mold, water damage, or moisture, or smell mold, there is at least some increased health risk. The more extensive or severe the dampness and mold, the greater the risk of health effects. We do not know whether specific types of mold are responsible, or whether bacteria or chemical emissions related to dampness also cause some of the health problems. www.cdph.ca.gov lists the health effects most associated with dampness and mildew as:
Generally, your reaction to mold will be determined by the type of mold, the level of exposure and your susceptibility to it.
The following features will ensure you get the best protection and the utmost convenience from your dehumidifier for mold.
This is important to ensure you get a dehumidifier that will sufficiently optimize the humidity levels in your intended room without getting overwhelmed. Measure your space, including the height, to match it with the model designed for that size of coverage.
If you are unsure, always go for a dehumidifier with a larger coverage than your room because it will be better equipped to handle any drastic changes in humidity levels.
Water tank capacity often corresponds with the size of coverage. Models with extensive coverage feature large water tanks which can accommodate the large amount of excess moisture removed from the air. If your room has high humidity levels, you will need a spacious water tank to collect the high volume of drawn moisture. Otherwise, you will have to empty the tank frequently. One way you can get around this is by purchasing a model with continuous drain option.
This is one of the most convenient features in a dehumidifier for mold, especially where there are high levels of humidity which subsequently produce large amounts of extracted moisture. In the absence of this option, you would be forced to empty the rapidly-filling water tank numerous times. The Ivation 50-Pint Dehumidifier, Frigidaire 70-Pint Dehumidifier, and Tosot 30 Pint Dehumidifier feature continuous drainage option which lets you connect a hose to the dehumidifier, and then divert the water to an external drainage system like a sink or sewage. Since these models do not have pumps, you have to position the dehumidifier at an upper level to the drainage system so the water can drain using gravity.
Dehumidifiers use fans which are responsible for the noise produced. That is why changing the speed of the fan to a lower setting generates a quieter sound.
For example, the number of decibels produced by Tosot 30 Pint Dehumidifier reduces from 52 to 50 to 48 decibels as the fan speed decreases from high to medium to low respectively.
Dehumidifiers with pumps and compressors are louder than those which use thermoelectric or Peltier technology, such as OXA Smart Mini Dehumidifier, because of the additional buzz and vibration.
You will obviously need a dehumidifier that will fit into your intended room and one that can be easily moved from one room to another if the need arises. There’re many types and sizes of these appliances available. Crawl space dehumidifiers are designed compact yet powerful to cover large spaces. RV dehumidifiers are usually tiny and are unable to cover more than 200 square feet.
Size also matters because it is an excellent indication of the dehumidifier coverage area. Models designed for usage in small rooms are compact and portable so they can fit in tight spaces such as closets, cabinets, and cars. Larger areas require massive water tanks to collect a large amount of extracted moisture, which makes those units big in size. The best demonstration of this is OXA Smart Mini Dehumidifier with dimensions of 5.9 x 7.1 x 7.1 inches versus Frigidaire 70-Pint Dehumidifier which measures 24.5 x 15 x 11.7 inches.
If the unit is fairly large and bulky, manufacturers often add handles and wheels for smooth mobility.
