For larger homes with an excess of moisture, look no further than the Tosot 70 Pints dehumidifier with pump. While some dehumidifiers require you to manually remove the water, this device has a handy internal pump which allows you to easily remove the moisture in a continuous automated way. In fact, even if the pump needs to move water up, it will still work, up to a distance of 15 feet. If you plan on placing the dehumidifier in a basement, then this is the product for you.
In addition to the internal pump, another great feature is the noise level, or rather, the lack of noise it produces. Measuring at only 52 decibels, maximum, the Tosot 70 pint dehumidifier is whisper-quiet. So if you need to place it in a family room or bedroom, no worries as you can still carry on a conversation or sleep easily. Previous users reported that they often forget that the machine is even on because it is so quiet.
As for the controls, the LED display is easy and convenient to use. There are no reports of user frustration, which is essential when dealing with mechanical devices. There are three fan speeds to choose from which gives you nice variability for those more humid summer months.

This Energy Star certified appliance has a coverage area of up to 4000 square feet, which is perfect for even larger homes. It can process 70 pints of water per day which means that even if you live in more humid climates, this dehumidifier will still meet your needs.

The dehumidifier will run for a continuous 24-hour cycle and has an automatic shut-off once the tank is full. If, however, you don’t want the hassle of manually draining the reservoir, no worry as you can also hook up a drain hose for continuous draining. The drain hose is not included, but again, users report that it is very easy to hook one up and usually a standard garden hose will suffice.
Because the hOmeLabs 4000 Sq Ft Dehumidifier is a portable machine, it is meant to be in a room and not in a basement. Don’t worry, though, as its modern white design can easily blend in with most aesthetics. It’s also slim enough to fit between furniture so it doesn’t have the be the focal point of a room.
Some whole house dehumidifiers are meant to be seen inside a room. Others, like the Aprilaire 1820 are best kept behind the scenes, such as a basement, crawlspace, or other ducted area.
This heavy-duty dehumidifier works to keep humidity levels stable in traditionally moist areas, allowing you to be at peace with the knowledge that both valuables and home structure are being kept safe.

As for draining, you can simply place the dehumidifier over a drain or set up the hose to the drain. The filter only needs to be cleaned once a year. It is incredibly low maintenance, and while it does come with an impressive five-year warranty, chances are that you won’t need to actually use it.
While so many products are now being manufactured overseas, one final feature of the Aprilaire 1820 is the fact that it is designed and built in the USA: it’s always nice to support local economies.
The Dri-Eaz F413 Revolution is a serious business. This is not a dehumidifier that is meant simply for a bedroom or a small apartment. Rather, it is a machine that resembles a commercial dehumidifier, and it is built to help with your whole house.

Basements can be tricky rooms of the house. They offer bonus space but have the unfortunate side effect of easily becoming too damp. As a result, wood furniture and even wood structures can become damaged over time. To protect your possessions and the house itself, it’s important to invest in a dehumidifier such as the AlorAir HDi90 Basement/Crawlspace Dehumidifier.
This unit has a coverage area of 2200 square feet, which is perfect for the basement of an average-sized home. It can remove up to 90 pints of water per day. This water is easily passed through the machine and emptied via a hose or the dehumidifier itself. Simply place the device or the hose over a drain pipe. Then you won’t have to worry about full reservoirs.
The settings are easy to manage, in large part thanks to the optional remote control that you can purchase. So, if you want to place the dehumidifier in a hard-to-reach area and are worried about adjusting the settings in the future, no worries.

Things to Consider
Before taking the plunge and purchasing your new whole house dehumidifier, it’s important to understand as much information as possible. Read on through this buying guide to help you reach your decision.
What benefits a whole house dehumidifier can bring to you and your family?
A whole house dehumidifier is perfect if you want your entire family to benefit from it. While many homes will have a humidifier in a room, this will only benefit those who use the room. Therefore, especially if you want everyone to have the benefits of a dehumidifier at night, then a whole house product is a great investment. By controlling the humidity in your house, no matter what time of day, you can ensure that the air is as dry or moist as you want it. Better air flow, cleaner air, and less bacteria are all benefits of a whole house dehumidifier.
Whole house dehumidifiers are often placed in the basement or crawlspaces, areas that are generally moister than others. When you stop moist air from forming, you can stop mold and wood rot from occurring, thus ensuring the structural integrity of your home.
Features to consider while choosing a whole house dehumidifier
The following are important features to consider before you purchase a whole house dehumidifier.
The performance of a dehumidifier is measured in just how much water is extracted from the air each day. Most products have a dehumidification performance of between 70 and 90 pints. If you live in a particularly humid climate, this performance should be at the higher end so that you can regular the air to a lower humidity level more quickly.
Usually, the larger the coverage area, the more expensive the model is, so be sure to only purchase a dehumidifier for the area that you need, in order to save a few dollars.
CFM stands for cubic feet per minute and refers to the amount of air that a dehumidifier can cycle through at one time. For example, the Aprilaire 1820 has an airflow capacity of 160 CFM and is best for smaller areas, or places that aren’t too humid to begin with. Heavier duty machines, like the AlorAir HDi90 Basement/Crawlspace Dehumidifier can extract a lot more humidity and are meant for very humid climates.
Dimensions and weight
Despite their power, whole house dehumidifiers are actually quite compact in size. Most are rectangular in shape with the largest size usually less than two feet long. It’s always a good idea to measure the space where you want to install your humidifier to make sure that it will fit. Some dehumidifiers that are meant for basements and crawlspaces will have suspension kits available. This way you can attach the device to the wall or ceiling to keep them out of the way but still functioning.
Just be sure that the hose is long enough to attach from the dehumidifier to the drain pipe. This way you won’t have to empty the water reservoir on a daily basis.
The warranty on a whole house dehumidifier can range from one year to five years. Especially if you purchase a dehumidifier with a shorter warranty period, be sure to maintain your product for a large life span. Regular cleaning and replacing of air filters will help give you as much life as possible from your whole house dehumidifier.
Beyond the initial performance of a dehumidifier, extra features can really make a product stand out. If you want to set your dehumidifier and not have to worry about it, then choose one that has an easy-to-read LED or LCD control panel. Some dehumidifiers also come with smart technology so that you can monitor the device from a smart phone and make any adjustments while you are away from the house.
For those who are particularly handy, or are able to follow instructions, then installing a whole house dehumidifier is actually quite easy. Some whole house dehumidifiers will have installation kits included with them; if not, then you may have to purchase a separate kit for installation. There are fortunately many online videos that will walk you through the necessary steps. For those who are not technically savvy, or are hesitant to start a new project, there is no shame in asking for professional help. For a dehumidifier to work to the best of its abilities, the drain pipe needs to be connected properly and if not, then you can be creating the type of leaks that you are trying to avoid in the first place.
Whole house humidifiers work best when they are clean and properly maintained. Depending on the model, they can be a sizable investment, so it’s important to get the longest possible lifespan out of them. The biggest part of maintenance is changing the filter pad. This should be done once per year. One other important maintenance tip is to periodically check for leaks. Because a whole house humidifier is often in a basement or less-often used part of the house, it can be forgotten. Try to make your way past the dehumidifier to check for leaks so that you can fix them before they become too serious.
The best way to control the humidity level in your home is with a digital humidity control panel. Just as you would have a control panel with your furnace, a good whole house dehumidifier should have a panel as well. There you can select the proper level that you want and once your house has reached that level, it will automatically shut off. Generally, humidity levels should be between 30 and 50%, with variants in there for personal preference. Even if you experience a hot, humid summer, it’s best not to adjust the settings. Let the humidifier work. It will run until it needs to and will shut off only when the prescribed settings are achieved. Note, though, that there is a maximum amount of water that can be removed from the air in a given day and in periods of extreme humidity, it can be hard for the settings to be achieved.
All of the products on our list are here for a reason, but if you are looking for something specific, these are our top three suggestions. The best whole house dehumidifier on our list is the Tosot 70 Pints Dehumidifier with Internal Pump. Its internal pump and large, 4500 square foot coverage makes it really stand out. It has a lot of great accessories, making it a whole house dehumidifier system that is well worth the investment.
If you need a dehumidifier but are on a budget, you can’t go wrong with the hOmeLabs 4000 Sq Ft Dehumidifier. This portable machine offers 4000 square foot coverage and can remove 70 pints of water, making it both user-friendly and powerful, which is a winning combination.
The final recommendation if you are looking for the best whole house dehumidifier is the Aprilaire 1820. This is perfect if you want an inconspicuous device for your basement or crawlspace. It is powerful enough for the average-sized home and really works to eliminate mold, bacteria, and general rot.
