The Frigidaire FFAD7033R1 efficiently lowered the relative humidity in our test basements from 65 to 70 percent humidity to 45 or 50 percent, a level that inhibits mold yet remains comfortable to breathe. It held those levels consistently even during a week of nearly nonstop rain (like all our picks). It has the best interface of any model we tested, with large buttons and legible text easily visible in dim light. Detaching, emptying, and reattaching the reservoir was easier than on any other model we tested. It’s relatively quiet, it has a useful handle and wheels, and it even looks pretty nice, if you have to use it in a living space. Frigidaire is easier to deal with on warranty issues than most smaller brands, and this model is usually in stock online or at major retailers.

Is very good for energy efficiency. Is excellent for water removal. Is very good for humidistat accuracy. Is very good for noise.
- Consumer Reports
Frigidaire has a lot of dehumidifiers on the market, but this particular model hits all the sweet spots with very few downsides. It’s Energy Star rated to help you save money, and can remove up to 50 pints of water from your home each day to cut down on moisture. The tank itself can hold around 13 pints, and has pullout and splashguard features to make getting rid of the water much easier. There are also connections so that you can hook the model up to a drain for continuous operation – more suitable for workplaces or trailers. The electronic controls include a digital humidity reading, a timer for setting schedules, and other basic modes. We aren’t overlooking the design, either: This dehumidifier skips the common radiator-like design for a smoother, friendlier appearance that we appreciate.
- Digital Trends
It's not surprising that the Frigidaire FFAD7033R1 is one of the most popular dehumidifiers on the market. This no-nonsense dehumidifier managed to reduce the relative humidity by about 50% in about an hour and 40 minutes. While it doesn't have hand-holds, the FFAD7033R1 has a large handle and wheels that allow it to move easily. The filter is mounted on the back of the dehumidifier, and is easy to remove and clean as needed. The Frigidaire FFAD7033R1 is a great workhorse dehumidifier.

If you need a large capacity dehumidifier that handles 70-pints per day in moisture this pick from Frigidaire is a winner. Use it in your basement, attic or anywhere dampness lurks. In order for it to handle this large capacity, it is best to have it by a drain so it can properly dispose of the water when it needs to or you have to dump this every 12 to 24 hours. Users love that it is quiet and that it pulls a lot of moisture out of the air keeping it at their optimal percent of humidity. For anyone that needs heavy-duty dehumidifiing, this is a smart option.

This model had no discernible flaws in its performance.

By comparison, the Frigidaire FFAD7033R1 only collected 11.2 pints. That translates to roughly 67.2 pints over 24 hours -- less than the manufacturer's expected 70 pints.

An Overview On Dehumidifiers

Humidity can cause serious problems, especially in poorly insulated rooms like basements. Over time, moisture can cause mold to build up, potentially affecting the health of you and your family. It can also cause wood to swell or deform, possibly impacting the entire structure of your house. The right dehumidifier can pull the moisture from even large spaces, with the water filtering directly into a drain.

If you have high-moisture areas of your home, a quick mold check will tell you whether you need a dehumidifier. The most common type of mold is alternaria, which is dark in color and can cause allergy-like symptoms. Even if you don’t see signs of mold in high-moisture areas, though, it may develop in the future. If you have an area of concern, a dehumidifier can pull the moisture from the air, reducing the risk that mold will begin to grow.

Once you’re in the market for a dehumidifier, you have some decisions to make. You’ll need a way to hook your dehumidifier up to a drain so that you won’t have to empty it every day or so. If you’re concerned about moisture in a small area like a pantry or closet, the Eva-Dry is an innovative concept that uses moisture beads to soak up the moisture. Its small size also means it won’t take up too much space.

You should also consider noise level, especially if your dehumidifier is in a space of the home where people spend time. You won’t want your dehumidifier to interfere with nightly TV watching or your quiet reading time. Dehumidifiers have varying noise levels that should be part of your buying decision.

Lastly, consider your monthly utility bills in your choice. An Energy Star-rated dehumidifier will save you money in the long run, while also keeping your home environmentally friendly. You’ll get the same efficiency with a fraction of the energy use.

DYWM Fun Fact

Weather isn’t the only thing affecting moisture levels in your home. In fact, many of your everyday activities can contribute to moisture-related issues, such as mold and wood deformation. Bathrooms and kitchens are especially susceptible since water is an important part of your activities in those rooms. Showering, cooking and even doing laundry can generate humidity. Moisture also gets into homes via basements and crawl spaces, so that humidity under your house may actually be a bigger problem than you realize. If you have plants, they also contribute to moisture in your home, with experts estimating one plant releases 0.5 liters of moisture per week.

The Dehumidifier Buying Guide

  • The top concern for any dehumidifier purchase is effectiveness. The Frigidaire does well in medium-size rooms, dropping humidity from 65 to 70 percent down to between 45 and 50 percent. This level is low enough to keep mold at bay while still being comfortable. Best of all, it holds that level consistently throughout the day. The GE, however, is less efficient, keeping the humidity range between 35 and 80 percent. The LG is efficient in larger rooms, controlling humidity in areas up to 2,000 feet. Meanwhile, the Eva-Dry only works well in small spaces like closets and pantries, where it reduces relative humidity by 19 percent in less than a couple of hours.
  • When it comes to capacity, it looks like 70 pints is the gold standard in dehumidifiers. The Frigidaire, GE and LG all boast a capacity of 70 pints. The Eva-Dry is different from the others in that it uses desiccant silica beads to absorb the moisture. Simply wait for the crystals to turn green and plug the unit in for eight to ten hours in a well-ventilated area. At that point, you can reinsert the crystals and start soaking up humidity again.
  • If you want to add a new dehumidifier without seeing your electricity bill increase, the Frigidaire and LG PuriCare are Energy Star-rated. The Eva-Dry is also worth considering if you’re concerned about moisture in small areas of your house since it only needs to use power while the moisture beads are renewing.
  • Setting up and using your dehumidifier will require some work, regardless of the model. However, the Frigidaire’s large buttons and legible text make it easier than average. The text is also easy to see in dim lighting. Best of all, it has a timer so that you can set a schedule for your dehumidifier to run.
  • As your dehumidifier pulls moisture from the room, it gathers into a bucket that will need to be emptied. With the Frigidaire, you can set the unit up near a drain to allow it to dispose of water on its own. Without this, you would have to empty the bucket every 12 to 24 hours. The GE and LG can also connect to a drain to prevent you from having to empty the bucket.
  • Unless your dehumidifier is in an unused basement or closet, chances are noise level is an important factor. If silence is a priority, the LG will be the best choice, since it’s quieter than the rest. The GE is slightly noisier than the others, but still relatively quiet. While the Frigidaire runs quietly, it does get noisy on the highest setting.
  • When it comes to cost, you can’t beat the price on the Eva-Dry, which sells for less than $20. Since the Eva-Dry only works well in small spaces, though, you may need to choose between the others, which all fall in the $200-$300 range. The GE model is slightly cheaper than the others, at just over $200.
