Frigidaire FFAP7033TT1 70-Pint Dehumidifier with Built-in Pump – Best Overall

If you’re having humidity issues in your basement, we believe you will love the Frigidaire FFAP7033TT1. For starters, it has a built-in pump that ensures a continuous discharge of water without relying on gravity. It is a 70-pint dehumidifier featuring easy to use controls. With 51 decibels, this dehumidifier has a relatively quiet operation and a low-temperature operation. 

There’s also an option to empty the tank manually. If you’re on a budget and wouldn’t mind emptying the tank now and then, you can opt for this Frigidaire Dehumidifier with no pump. It is cheaper and equally effective. 

This dehumidifier measures 11.6 inches by 15 inches by 24.4 inches. It features a sturdy plastic build. It may look dull and less beautiful, but that doesn’t matter since you will place it in the basement. It also weighs 47 pounds, but thanks to the caster wheels, you can quickly move it around the house. And that’s not all, the wheels have a locking mechanism to prevent the appliance from rolling over.

User Critic

Most users agree that this dehumidifier is a workhorse. It is large, drying out large basements within a short time. The pump is also efficient since the user doesn’t have to empty the tank. However, some complained the pump broke down often.


  • It is relatively quiet.
  • The pump and continuous drain make it easy to use.
  • It has easy to use controls and alerts. For instance, it stops running when the tank is full and starts again after the pump has drained the tank.
  • The caster wheels make it easy to transport.


  • The power cord is quite short.
  • The pump hose connection is small and flimsy. Due to the small diameter, you have to keep the dehumidifier running for a long time, consuming a lot of power.

The Verdict

We recommend this dehumidifier to anyone with a basement, for it has everything you would look for. It has a large capacity, a pump, and it’s easy to use and maintain.


hOmelabs 70-Pint Dehumidifier – Best Value for Money

This dehumidifier has been designed specifically for huge rooms, including basements. You can opt for the one with a pump, or choose the continuous drain. Either way, this is a cheaper option when compared to the Frigidaire FFAP7033TT1. It comes with handles and for caster wheels for transportation. However, unlike the Frigidaire, the handles’ height isn’t adjustable.

It’s easy to set up, but you will have to wait for about 24 hours before using it. One distinct feature of this dehumidifier is the comfort feature that enables it to set a humidity level based on the room’s temperature. It also features a touch screen control panel and an auto-shutoff feature when the tank is full.

To ensure customer satisfaction, the manufacturer provides a two years warranty and exemplary support. The 70-pint dehumidifier is enough for 2500 to 4000 square feet. However, if you have a smaller space, you can choose the 50-pint dehumidifier.

User Critic

Most customers loved this dehumidifier for its affordable, sufficient, and the manufacturer offers excellent customer support. However, many users had an issue with the cheaply built exterior and the poor design that may cause the growth of molds.


  • The electronic Control Panel makes it easy to change the settings.
  • The filter is easy to remove and clean.
  • It also has a relatively long power cord.
  • The handles and caster wheels also make it easy to move around.
  • The manufacturer offers a 2-year warranty and one of the best customer service.


  • The handles aren’t adjustable, making it better to carry it in a box to the basement.

Like the Frigidaire and the hOmelabs models, this Vremir dehumidifier is Energy Star certified. This means that it’s effective at minimizing moisture with minimal power consumption.

FAQ (Frequently Asked Questions) About Dehumidifiers for Basements

Where should I place the dehumidifier in the basement?

The humidifier’s front face should be facing the source of humidity or the broadest part of the room. You can place it anywhere as well as long as there’s a six-inch gap from the appliance to the wall. In some instances, it has been proven useful to put it in the middle of the room.

Dehumidifier with a pump vs. a dehumidifier without a pump?

An internal pump is handy since it pumps water vertically, while those with no pumps have to rely on gravity. Those with pumps are always the best, but they are costly, and the pumps may break down often. If you don’t want to deal with such inconveniences, you can choose to connect a hose for continuous draining.

What’s the best size for a dehumidifier for basements?

The size depends on the dimensions of your basement. However, since basements always have a lot of humidity, so the larger, the better. By large, we mean the amount of moisture that the appliance can draw in a day. You shouldn’t go for anything less than a 50-pint dehumidifier. This will ensure that you remove the humidity faster, and you may not have to empty the tanks often.

How does a dehumidifier work in a basement?

Dehumidifiers work by extracting moisture from the atmosphere and converting it into water deposited in a tank. There are two types of dehumidifiers, those that use a refrigerator and those that use a desiccant. Desiccant dehumidifiers, on the other hand, extract the moisture and let out dry air. Refrigerator dehumidifiers are the most common since they are faster and cheaper.

Why does your basement need a dehumidifier?

Excessive humidity is risky. It may lead to the growth of molds and mildew, which may cause allergic reactions. Since basements are some of the areas that accumulate a lot of humidity, we believe dehumidifiers are essential. Based on the reviews, it’s clear you can use these appliances for other purposes like drying laundry and even repurposing the extracted water in your garden. Also, if you haven’t seen extreme manifestations of humidity, purchasing this gadget as a preventive measure is still advisable.

How To Choose The Best Dehumidifier For Your Basement

A lot goes into choosing the best dehumidifier for your basement. We may have reviewed some of the best, but if you don’t know what you’re looking for, you may still be confused. Below are some of the factors you need to consider when purchasing a dehumidifier.

Size Of The Basement

The space that a dehumidifier can cover is often labeled in terms of square feet. For instance, we have included a range of 410 to 4500 square feet. So you need to calculate the size of your basement and purchase a dehumidifier that matches this size. As mentioned earlier, you can buy one that’s slightly larger than the room for flawless operation.

Room Temperature

Dehumidifiers can work at specific temperatures. When this temperature is exceeded, or it drops below what’s recommended, it may not work. Purchasing one that can function in low temperatures is the best idea.

Quiet Operation

Due to the fan and other internal operations, these gadgets can produce unpleasant noise. If you don’t carry out your activities in the basement often, the amount of noise may not be a bother. However, since you may need to use it for the whole house, you should go for a dehumidifier with quiet operation, 55 decibels or lower.

Additional Features

Additional features such as timing, Alexa voice control, auto-restart, auto-humidistat, and auto-shutoff make the basement dehumidifiers more effective. The good news is that even the cheaper models have most of these features.

Advantages Of Using A Basement Dehumidifier

  • Eradicating allergens – Dampness provides favorable conditions for molds, dust mites, and mildew. These pollutants cause allergic reactions to people with Asthma and other respiratory diseases. A dehumidifier makes it safer for people to spend time in their house.
  • It makes the room more comfortable to live in – Dampness makes it hard to breathe. By minimizing the humidity, you make the basement and the whole house more comfortable. You also eradicate the musty smells.
  • It creates a conducive environment for your tools and foodstuff – If you have tools in the basement, they may rust as a result of the humidity. It also protects your home beams and other structures from warping. You also get to keep your dry food fresh for a longer time.
