Best Dehumidifiers TechnoBuffalo 2021

Home and office spaces with high humidity levels are often times prone to mildew and mold proliferation. A musty odor, water droplets on windows, and wet wall patches — these are telltale signs of damp in the air. The ideal moisture content in any room should typically be about 30-50%. At times, structural ventilation and air conditioners can fail us. That's when dehumidifiers come in. We have listed the best dehumidifiers you can consider. Top of the list is the Keystone High-Efficiency 50-Pint Dehumidifier. The dehumidifier has castor wheels for smooth movement and a full tank alert that automatically turns off once the water tank is full.

Best Overall: Keystone 50-Pint Dehumidifier

There are two factors you should consider when buying a dehumidifier: the size of the room and the extraction capacity of a dehumidifier. The Keystone High-Efficiency 50-Pint Dehumidifier is optimized for spaces measuring up to 4500 sq ft. Depending on how damp the area is, the machine can extract up to 50 pints of water in 24 hours. The moisture is condensed into a water bucket tacked in at the front. Once the bucket is full, the dehumidifier alerts you and shuts off. For more convenience, you can connect a hose to the dehumidifier, so the extracted water continuously drains out.

At the top of the Keystone is a touch control and notifications panel. The dehumidifier works in two modes, turbo and normal. For added convenience, it has a 24-hour timer and a humidistat that displays humidity levels. If there is a power outage, the auto-reset function saves and restores your preferred settings, saving you the hassle of starting from default settings.

  • Full tank alert
  • Removable and washable air filter
  • Castor wheels for easy movement

Best Rechargeable: Eva-dry E-500 Mini Dehumidifier

The Eva-dry E-500 Mini Dehumidifier is quite tiny and works well in small enclosed areas up to 500 cubic feet. We have all kept clothes and documents in a closet and desk drawer, respectively. After a while, the clothes and papers smell like damp and feel wet. The culprit? Excess moisture. Enclosed spaces like safes, closets, desk drawers, under the kitchen sink are all prone to high humidity. The humidifier works without batteries or a power outlet.

The Eva-dry mini dehumidifier uses silica gel instead of batteries or a power outlet. Inside the dehumidifier are orange crystals visible through an indicator window. Excess moisture and musty odor are extracted and trapped by the gel. Once it hits its capacity of six ounces, the orange crystals turn green. You then plug it into a power outlet for about 12-14 hours to renew the crystals. Once the crystals go back to orange, it is ready for use again. The dehumidifier is usually good for 3-8 weeks, depending on the size of the space and amount of humidity.


  • Ten-year life span
  • Safe for pets and kids
  • Rechargeable over and over
  • Portable


  • Ideal for small spaces only

Bottom line

Dehumidifiers are essential household appliances. They help balance humidity levels, guaranteeing the structural and health benefits of a damp-free home. The Keystone 50-Pint Dehumidifier remains our best dehumidifier. It is built to work in any space less than 4500 sq feet. The well-designed touch control panel is home to a range of customizable dehumidifying settings. It has an auto-reset function, which will save your last preferred setting in case of a power outage. Besides, the price is just right.

You better be safe than sorry! Controlling humidity levels from the onset is better than the hassle of getting rid of mold, mildew, and that musty smell. Over time, dust mites and bacteria will get trapped in the air filter. To prevent malfunction, most air filters are removable and washable. When buying a dehumidifier, it is advisable to buy a bigger one rather than a smaller one. Why? Scaling down is more natural than scaling up!
