The Best Dehumidifiers

Table of Contents

Basements, bathrooms and other areas of a home are notorious for being perpetually damp. Too much moisture can lead to mould, mildew, and high humidity that can damage clothing, furniture, and sometimes your health. A dehumidifier is designed to extract excess moisture from the air to create a more balanced environment.

Dehumidifiers work best in a right-sized space. When choosing a dehumidifier, always make sure it is not being used in a larger or smaller space than what is recommended for that particular model.

Read more about the different dehumidifiers you can purchase online to make an informed choice when shopping for one for yourself.

Even the most unusual places can become damp — a gym bag, a gun locker, a cabinet, the car, or even a closet. In these situations, removing excess moisture is important to reduce the risk of mildew, mold, or warping, but a traditional dehumidifier won’t fit or work in such a small area.

This ultra mini dehumidifier is spill- and mess-free, non-toxic, child- and pet-safe and is designed to absorb moisture from small enclosed areas with a maximum dimension of 10’ x 10’.

Super convenient and easy to use, this product is 100% renewable and needs no power to operate. Just hang it in a closet, or in another small, enclosed space, and it will start to absorb moisture. It doesn’t need batteries or an electrical outlet to work.

Absorbing approximately 8 to 10 ounces of moisture, it won’t leak or spill. There is an indicator window with "moisture metre crystals," that change from orange (when dry) to green (when wet) to indicate when the unit needs to be ‘renewed’ or recharged. Engineered with non-toxic crystallized silica gel technology, it will last for between 20 and 30 days before needing to be renewed.

When the indicator is green, just remove the dehumidifier from where it is absorbing moisture and plug it into a power outlet to recharge and watch the silica beads change colours back to red. It’s that easy! This dehumidifier will work for up to 10 years and is 100 per cent renewable.

Anyone who lives in a humid climate understands all too well the toll excess moisture can have on a house. From warped floors and wavy carpets to persistent mold and mildew, these side-effects can range from aggravating annoyances to potential health hazards.

For situations where large areas need to be dehumidified every day, all day, we recommend this model from Tosot that can remove up to 50 pints of water every 24 hours in spaces up to 4,500 sq. ft.

The internal pump in this sophisticated machine automatically removes collected water from the dehumidifier so there is never any downtime because of a full water bucket. As well, water can be pumped sideways or vertically up to 12 feet away and when the bucket is almost full, the internal pump will automatically start up to remove the collected water.

Other features of this dehumidifier include real-time monitoring, which means after a target humidity level is chosen, the control panel will display the current humidity level and the dehumidifier will turn off when the target it met; a peak sound level of 51 decibels; Energy-Star rated; and the ability to have the dehumidifier run nonstop regardless of the humidity level.

What to Look for When Choosing a Dehumidifier

Size of the space: Perhaps one of the most important factors to consider before purchasing a dehumidifier is to determine the size of the space that needs dehumidification. Similar to an air conditioner, a dehumidifier will work best in a space that is suited to the machine’s optimal output in a specifically sized area. Most models will outline the ideal square footage for operation, so read the specs carefully before making a choice. Luckily, there are dehumidifiers that work well in large areas like a house, mid- to-small-sized rooms like a bedroom, bathroom, kitchen or basement, and even mini-humidifiers to take the dampness out of enclosed places like a closet, cupboard, or even a sweaty gym bag.

Level of humidity and temperature of the room: Most dehumidifiers are sensitive to the relative humidity in the air they are working in, plus the ambient room temperature. For example, some machines work best at a room temperature between 68 and 86 degrees Fahrenheit (20-30 degrees Celsius) with a relative humidity of 80 per cent. Other dehumidifiers do not function well below 15 degrees Celsius. While this may sound fussy and too technical, it doesn’t pay to use a dehumidifier incorrectly, as it just will not perform well. Before choosing a model, always read the specs carefully to make sure you can meet the optimal working requirements of a unit.

Moisture absorbency: Dehumidifiers remove moisture at different rates and speeds, so it’s best to choose the one that reflects your specific needs. Only you know the best level of humidity that will reduce or eliminate the dampness in a specific room. Prolonged dampness can lead to the build up of mildew and mold, which can eventually cause serious health problems.

Some dehumidifiers will remove 250 ml of moisture a day, while others will absorb 500 ml and more. Make sure the model you purchase mentions these details so you can accurately determine if it will solve the specific situation in your home.

Features: Some features to consider to make your experience a positive one include:

  • Noise level — below 40 db is ideal as the quieter the better so it doesn’t disrupt anyone’s sleep or daily living
  • Water tank — should be large enough that it doesn’t have to be emptied all the time
  • Shutoff feature — when the collection tank is full, it’s good when the dehumidifier automatically shuts off so the tank doesn’t overflow
  • Internal pump — some dehumidifiers have an internal pump that gets rid of the water in the collection tank, which is convenient for very damp houses with lots of humidity and for anyone who doesn’t want to have to empty the tank
  • Energy efficiency — running a dehumidifier all day can elevate electrical bills so choose one that has a low power consumption is reader-supported.
