Though this dehumidifier comes with a hose connection in case you want to automatically drain the removed water into a nearby sink, it doesn’t come with the pump or hose.

Pros and Cons

✔ Includes an automatic shut-off feature for when the tank is full
✔ Has a turbo mode for increased fan speed and moisture removal
✔ Available in other models that filter more or less water and come with or without a pump

✘ Doesn’t work in the same room as an evaporative cooler
✘ Requires a separate purchase if you want to drain it with a garden hose

What Customers Are Saying

Many customers were able to remove moisture from their air in just hours after this dehumidifier arrived, as it was easy to assemble and fast-working. They also mentioned its durable construction.

Buyer’s Guide

To help you understand the benefits and workings of a dehumidifier, we created a buying guide. Considering the information below can help you make an informed purchase.

Capacity

A dehumidifier’s capacity is measured by the amount of water it can remove from the air in a set amount of time, typically 24 hours. A dehumidifier with a larger capacity can treat a larger room.

If your home is moderately humid, here are some general guidelines for how dehumidifier capacity lines up with room size:

  • 30-pint dehumidifier for 500–2,000 square feet
  • 50-pint dehumidifier for 2,000–2,500 square feet
  • 70-pint dehumidifier for 2,5000–3,000 square feet

If your room has a humidity level above 70%, size up. For example, choose a 50-pint dehumidifier for a 1,000-square-foot room that’s at 80% humidity.

Tank Size

The tank collects the moisture that the dehumidifier draws from the air. The tank usually holds one or two gallons of water, so you have to empty it several times throughout the day to ensure that the dehumidifier can continue to run up to its rated capacity.

Select dehumidifiers, especially larger ones, have a garden hose connection to feed the water into a nearby floor drain, sump pump, or bathroom sink automatically.

Control

With some dehumidifiers, you simply turn them on to get them going. Others feature dials, buttons, or other controls to customize their operation. For example, you can set the dehumidifier to only pull moisture from the air until your room reaches your desired humidity level.

Noise

The compressors that dehumidifiers use to suck the moisture out of the air tend to be fairly noisy. If a quiet-running dehumidifier is a priority, look for a model that’s advertised as quiet. Some manufacturers may list the decibels at which the unit operates.


Why Should You Get a Dehumidifier?

Besides providing a comfortable living or working environment, a dehumidifier offers two other primary benefits.

  • Protects items: High humidity can warp wood floors, cabinets, and other items. You don’t want moisture to collect in your electronic devices either.
  • Removes bacteria: Bacteria, dust mites, and other harmful microorganisms thrive in high humidity. As your dehumidifier pulls moisture out of the air, they die.

How Does a Dehumidifier Work?

To give you a better understanding of how a dehumidifier removes moisture from the air, we created a step-by-step outline.

  • The process begins when the dehumidifier’s fan brings in the warm, moist air from your home.
  • The air passes over a series of pipes that are cooled by refrigerant.
  • As the pipes cool the air, the moisture is pulled from it, dripping down into the water collection tank.
  • The dehumidifier reheats the dry air to its original temperature using an electric heater before blowing it back into the room.
  • As the dehumidifier pulls water from the air, a plastic float rises with the water in the collection tank.
  • Once the tank reaches capacity, the float trips a switch that shuts off the fan.
  • Before the dehumidifier can start again, you need to empty the tank.

Frequently Asked Questions

Is it safe to run a dehumidifier constantly?

To be effective, a dehumidifier needs to run for an extended period of time. You can leave it running until the automatic switch detects that the water tank is full and turns off the motor.

When should I turn off my dehumidifier?

You don’t need to run your dehumidifier if your home is between 30% and 50% humidity. Instead of manually checking to see when you reach that level, you can usually set your dehumidifier to turn off automatically.

What is a whole-house dehumidifier?

The type of dehumidifier that you’re buying online only works in a small space. However, if you live in an area that’s hot and humid throughout the year, a whole-house dehumidifier may be a better option. It connects to your HVAC system and pulls moisture from the air whenever the system runs.

Consult an HVAC technician if this sounds like the solution for you.

Is it worth using a dehumidifier?

If you live in a notably humid area, it’s worth investing in a dehumidifier if you wish to make things around you drier. Additionally, some dehumidifiers, such as compact, portable models, tend to be fairly inexpensive.

If you wish to dehumidify your entire home, the unit will be pricier, but worth the investment if your home doesn’t have air conditioning.
