These features increase the efficiency of the device and also reduce worry after plugging in the dehumidifier. I have a basement with a cold room.
Why buy a dehumidifier?
The manufacturer does so by voluntarily sending it to AHAM for testing. The bottom-line here is that the chart is likely based on data obtained in a space much different than the space that you actually need to dehumidify.
The chart contradicts manufacturer recommendations. See this Friedrich dehumidifier brochure , for example. It recommends that a 70 pint dehumidifier be used for a 1, to 2, sq. The chart contradicts our own research and testing.
Clearly, we believe that the AHAM dehumidifier sizing chart has a lot of flaws. And, because of them, it is our strong recommendation that you do not use it to determine what size dehumidifier you should buy. So, what do we recommend? Our recommendation is simply the following:. In other words, we recommend that you buy a 70 pint dehumidifier — the largest capacity consumer-grade dehumidifier you can buy — regardless of the size or dampness of the space you need to dehumidify.
What exactly is that cost? Our recommendation that you buy the largest capacity for consumers this means 70 pint dehumidifier you can afford is based on the following very simple fact:. A 70 pint dehumidifier is certainly capable of removing a volume of 70 pints of water from humid air every day. A 70 pint dehumidifier removes any given quantity of moisture — not just 70 pints — at a faster rate in any given quantity of time — not just in 24 hours.
If this sounds confusing, think about it this way. A 70 pint dehumidifier is rated to remove 70 pints of moisture per day. This translates to 2.
A 50 pint dehumidifier can remove 2. Clearly, given a set quantity of moisture, a 70 pint dehumidifier can remove that moisture much faster than smaller capacity dehumidifiers. Compared to a 30 pint dehumidifier? Because it dehumidifies faster, a 70 pint dehumidifier needs to run for a much shorter period of time than smaller capacity dehumidifiers to dehumidify any size space under any conditions.
This is extremely important for the following reasons, which also happen to be the primary reasons why we feel so strongly about recommending 70 pint units:. It makes 70 pint dehumidifiers more energy efficient compared to smaller capacity units. You should be able to more than recoup the initial cost difference between a 70 pint and a 50 or 30 pint dehumidifier in energy cost savings over time.
It makes 70 pint dehumidifiers more reliable than smaller capacity units. This is perhaps the biggest reason why we recommend 70 pint units. You see, every minute that your dehumidifier runs puts stress on its internal parts its compressor, condenser, etc. Because 70 pint dehumidifiers have to run for a shorter amount of time than smaller capacity units to dehumidify any given quantity of air, the stress on their internal parts occurs over a much shorter amount of time.
This allows them to last much longer than smaller capacity units. Think of it this way: The math is simple. A smaller capacity unit has to operate for a far greater number of hours than a large capacity unit to dehumidify the same space with the same amount of moisture.
The percentage of complaints is much much higher for smaller capacity units. After several hundred hours of research, testing, and in-depth analysis here are our model recommendations for It is unequivocally the best dehumidifier on the market today. It removes moisture fast — We conduct two different tests to determine how well and how fast a dehumidifier can remove moisture in a real-world environment.
The same cannot be said for many of the other dehumidifiers we tested. The second thing the FFADR1 has going for it, in terms of noise output, is the fact that it exhausts out of its side. The FFADR1 exhausts out of its side allowing you to direct this noise wherever you want by simply rotating the dehumidifier on its casters. Most other dehumidifiers on the market exhaust upward in which case fan noise is always directed upward as well.
This type of noise distribution is much more difficult to manage. Placed directly next to other popular dehumidifiers it would be obvious even to someone with far less experience with dehumidifiers than we have, that the FFADR1 is clearly a much better built higher quality appliance.
It earns our highest recommendation as the best dehumidifier on the market today. Note that 50 and 30 pint versions of this particular model are also available for purchase. Both units are identical to the 70 pint version except for capacity and size. They have exactly the same control panel, the same exhaust location, the same build quality, etc. Of course, we do not recommend those versions over the 70 pint unit, but should you be set on purchasing a smaller capacity unit you can be confident that they provide similar noise output, exactly the same build quality, and most other benefits just the same as the 70 pint unit but at a smaller capacity.
We measure the noise output in dB using a sound meter for all of the dehumidifiers we test for review. The Keystone KSTAD70B removes moisture faster than most other 70 pint dehumidifiers we tested but more importantly, it removes moisture much faster than any 50 pint or 30 pint dehumidifier. It has recently come to our attention that the KSTAD70B is out of stock at most online retailers, indicating that it may have been discontinued by the manufacturer.
See Price on Amazon. Many other reviewers base their recommendations on manufacturer specifications. These specifications list performance data namely moisture removal rate and noise output that is based on testing conducted in a highly controlled environment which maximizes the performance of the dehumidifier and allows it to get ideal results.
We rigorously test each unit to determine how quickly it removes moisture, how much noise it produces, how much energy it uses, and just how accurate its built in hygrometer used to read humidity levels really is in a typical home environment. This means that our test data is often quite different than what manufacturer specifications indicate. This is how we determine the best dehumidifier in each category. We use the rating rubric below to give each dehumidifier we test a score out of 5 in each category.
These 13 scores are then added up to give the dehumidifier a cumulative score. It is largely this cumulative score that we use to determine the best dehumidifier in each size category.
Note that you can read our full review for each unit by clicking on its model name. Hello I live in the 1st floor of a low rise condominium In the Phil.
I do not often use my aircon but the room feels cool. To get rid of the mold i need a dehumidifier? Yes, a dehumidifier will help with your mold and general humidity issues. After you set a desired humidity level on the unit it will automatically turn on and off to maintain that level. When considering any electrical appliance with more electrical energy draw than a light bulb, I will always covert watts to amps.
A Wonderful piece of information thoughtfully provided by hOmeLabs. Thank you for the comment. We are definitely considering doing the same using amps instead of watts in future reviews and guides. Hello, Firstly, I would like to thank and recognise you for such a great article. Very informative and well written.
Both of these devices have a compressor and have a dehumidifier option on them. See our write-up on air conditioners and dehumidifiers here. Could you post the dimensions and approx weight of the top recommended models, please. I might ask family in the US to bring one when they visit, if at all possible.
Generally, units of the same capacity have a similar weight and size. Finally, 30 pint units weigh closer to 30 lb, are normally just under or around 20 in. I re-checked and you did have the correct model numbers listed…my aged mind is playing tricks on me. Loved your review…been looking for a good large capacity dehumidifier. Have an old Whirlpool that has worked great for years, but want to add a new one. Our guide for basement dehumidifiers which you can find here is applicable.
The thing that set the Frigidaire apart was its interface, which was the easiest to understand and use among all the dehumidifiers we tried. It was the quietest machine we tested, too, with the most manageable reservoir, and it was easy to move around with its handle and wheels—welcome graces no other model in the test group offered.
We bought a year round cottage in NW Pennsylvania with no air conditioning. Lots of ceiling fans. Square footage is about Sq ft. Someone suggested a dehumidifyer which would make the house feel not so hot. Trying to avoid having an air condition unit installed. Would dehumidifyer help us? Do they require drainage outlet of some sort? Yes, a dehumidifier will reduce humidity in the space which will make it feel cooler.
Most units drain into a built-in bucket that is removed and emptied manually every few hours. Most of these same units can also be drained externally by connecting a garden hose to them. I have heard that air conditioners are not that good at removing humidity anyway. Is there a small sized humidifier that I can use in conjunction with the air conditioner to keep the room comfortable. Obviously it would be better to have an air conditioning unit that is the right size…but this is the only size they have?
What unit would you recommend? Can you evaluate for me and others? How do you get the units for review? Do brands contact you and ask them to review your product? Do you purchase every unit then write a review? We recommend you contact your local department of public works to ask about disposal options for old appliances. Can you recommend 50 and 70 pint units that have a pump to remove the water to pump up about 4 feet and do not rely on gravity to drain? I am looking at the Danby and Frigidaire models.
See our 70 pint dehumidifier guide here for additional recommendations. A thorough review, thank you. Unfortunately, the top 2 are discontinued. What do you recommend in their place? Our top pick is not discontinued. When I go on vacation, the tank will fill up in a couple days and then just stop. We recommend purchasing a top rated dehumidifier and then buying a dedicated condensate pump and tubing separately.
Looks same as your top model but with a pump. See our comments about this unit in this guide. I have a basement with a cold room. The cold room gets really cold and drips water when the temperature starts to rise. Its like having cold water in a cup and the outside of the cup sweating. The exact same thing happens in my cold room Will a dehumidifier work in this situation. Please see our discussion on operating dehumidifiers at low temperatures here.
Industrial space in South Texas: Please see our guide on commercial dehumidifiers. I was wondering how well these dehumidifiers work in cooler temperatures, say around 40 F to 50 F?
Does the evaporator get cool enough to pull moisture out of the air at the temperatures previously mentioned? Please see here for a discussion on low temperature operation of dehumidifiers. We live in a small,old house sf plus a basement with no fans. When showering or cooking pasta the windows drip with condensation. Is a dehumidifier the best way to go other than renovating? I need a built in pump dehumidifier. I would assume it works and has functions similar to your top choice Frigidaire here.
We strongly recommend buying and installing a condensate pump separately. Currently, we are focusing our testing and research on units commonly found in the United States. Meaco units are, unfortunately, not readily available in the US. Your guide helped me quickly make an informed decision about my purchase. I looking forward to some quiet de-humidifying! Any idea what sort of chemicals, if any, are present after being run through the dehumidifying process? No chemicals are added to the air when it is processed by the dehumidifier.
For a full explanation of the process see our explanation here. My basement is a bit on the large side, with multiple finished spaces bedrooms, storage, bathroom, etc.
I have a Kenmore dehumidifier that is years old and it has a defrost feature in the event the coils ice up, which it seems to do frequently. Is this a common feature on all dehumidifiers? Does your top pick have such a feature? Does my icing problem indicate that a replacement is needed?
Yes, our top pick does have a defrost feature. Question — Some 70 pint units advertise sq. I have a sq. Will any 70 pint unit do the job regardless of sq. Will the Frigidaire perform as well as the Keystone? See here for our test results.
I checked and found from your article that this Fridaire model dehumifier does not come with a water drainage pump and so an extra pump is recommended if the user does not wish to have to empty the drainage bucket manually but wishes for the water collected from the dehumifier to be pumped into a larger contain, drain, or outside of the home.
I see that there is a a model with a built-in pump. A top-of-the-line dehumidifier is a fairly large purchase, so you might be on the fence about whether or not to buy one. Dehumidifiers decrease the likelihood of mold growth on your walls, around your windows, and in your linens and clothing. Small dehumidifiers in bathrooms help towels dry and stop mold from forming around tiles — especially if you don't have a ceiling fan.
She is a recognized media expert educating the public about home safety and wellness. To learn more about Caroline, visit www. If your basement floods, for example, you might take advantage of the turbo setting. We especially like the auto-defrost mode because compressor-driven humidifiers like this one have a tendency to freeze with constant use during high humidity. Keystone Features we admire include an air filter sensor, hour timer, and programmable humidistat.
A clear gauge on the side of the 1. Our lab testers noticed that the tank fits quite precisely onto the back of the unit and must be removed with care.
It's bulky and heavy when full. Think about how much moisture you'll need your dehumidifier to handle. Caroline says you need to purchase a dehumidifier that fits your size home and area you want to dehumidify, as well as the climate dew point is a more reliable measure to consider than temperature. Mini-capacity dehumidifiers remove 12 to 25 ounces of moisture per day. They're not designed to dehumidify whole living spaces but can be useful in bathrooms and crawl spaces.
Small-capacity dehumidifiers remove 20 to 30 pints of moisture per day, so they're best for small spaces that are damp but not wet. Medium-capacity dehumidifiers remove 40 to 50 pints of moisture per day. Use them for medium-sized spaces or large spaces that are only slightly damp. Large-capacity dehumidifiers remove up to 70 pints of moisture per day, so they can tackle large, wet spaces. When the dehumidifier is in a defrost cycle, the cost to operate the unit will increase, but the amount of water being pulled out of the air will be very minimal — cooler air does not hold as much moisture as warmer air.
If a system does not have a defrost unit built in the unit will freeze up and stop dehumidifying. Those with a dial typically allow you to choose between a few pre-set humidity levels, such as "normal," "dry," and "very dry. Look for a model with digital controls if you want to be able to set a specific humidity level as a percentage.
Many dehumidifiers have timers, letting you set the time of day you want the unit to switch itself on. This is useful if you want the appliance to run while you're out of the house, switch itself on at night when your electricity use is lower, or if you're simply likely to forget to turn it on. The pint-size Eva-dry Edv is designed for modest dehumidifying tasks.
This unit is light enough to be easily placed in a remote location like a crawl space and strong enough to keep a bathroom mold-free. However, it's not powerful enough to reduce the humidity in an entire living space, save perhaps for something small like an RV. All that moisture removed from the air has to go somewhere — and that somewhere is a tank inside the unit.
Each model is rated for a different cubic feet per minute CFM based on the capacity of the dehumidifier, explains Caroline. The greater the capacity of the dehumidifier, the greater the overall CFM of the dehumidifier. The larger the tank, the less often you'll need to empty it, but the heavier it will be when it's full of water.
Medium- and large-capacity units tend to produce about 55 to 67 decibels when running at full power. If you're going to be using the unit in your bedroom at night, look for models with lower noise levels. Make the most of your dehumidifier, and deal with dampness and humidity in your home, with these tips. Using a dehumidifier in a dirty room can spread dust and clog the air filter, if your unit has one. Vacuum before you use your dehumidifier for the first time.
Keep any spaces in which you regularly use a dehumidifier well-vacuumed and dusted. Station your dehumidifier at least an inch or two from walls, curtains, and furniture. Some of the products can be heavy. Be sure you are aware of the weight and size of the product before having it delivered one may need help getting the unit into a basement or crawlspace.
Washing and drying clothes indoors releases a lot of moisture into the air. Placed near your laundry space, a dehumidifier can make a positive difference in humidity.
Dehumidifiers can help with dampness, but they won't fix the root cause. The manufacturer says it can be used in a room of up to 2, cubic feet. Our tests show decent performance, but smallish Peltier-effect dehumidifiers do not perform anywhere near the level of monster compressor-driven models.
If you live in a climate with four seasons, you will need a dehumidifier that can dehumidify in colder temperatures without freezing up. It's worth noting that price doesn't necessarily equal quality with dehumidifiers.
Just because a unit is expensive doesn't mean it's good. Take a look at our top picks in the matrix above, or consult customer reviews to find out whether a specific model is worth its price.
Do I need a dehumidifier with a hose connection? A dehumidifier with a hose connection allows you to divert the collected water directly to a drain or sink so you don't have to empty the tank. This can be useful if you're running your unit in a basement with a floor drain or sink — or if the dehumidifier is in a practical location to divert the water straight out of the window into an outside drain or onto your lawn.
Will a dehumidifier help with my allergies? Running a dehumidifier can help reduce certain indoor allergens. Some allergens — such a mold and dust mites — need a humid environment to thrive. What is a humidistat? A humidistat tests the humidity in the air, so the dehumidifier can maintain the level you've selected.
How do I maintain my dehumidifier? You don't need to do much to keep a dehumidifier in good working order. Just make sure you clean the air filter about once a month, empty the tank every one to two days, and occasionally clean the tank to stop the build-up of limescale or bacteria.

Guides to Choose A Best Dehumidifier 2017 – 2018
To determine the best dehumidifier for basement or home, you have to keep in mind the existing climatic conditions around your home. Dehumidification is necessary for cold, damp conditions or in hot, humid conditions. For colder climates, a desiccant rotor dehumidifier is more effective because it doesn’t use cooling for moisture extraction. Best of the bigs in our Ratings is the pint Danby DDR60A3GP, $, which features a built-in pump that can expel water to an elevated drainage location, such as a basement utility sink. On the downside, its fan runs continuously, adding to its noise and energy consumption. We tested over 50 different dehumidifiers from a number of different brands, at different price points, and including different features and functionality. Our goal was to find the best dehumidifier .
