Best 70-Pint Dehumidifiers

If you live in a humid region, you probably know that all the moisture in the air makes it feel a lot hotter than it really is, and you know how good coming inside into air conditioning can feel! However, that cool feeling can trick us into thinking that we’ve escaped the humidity. Air conditioners do indeed reduce the moisture level in the air. Unfortunately, they don’t lower it by much.

When the air inside your home is humid, it leads to increased mold and mildew. Indoor humidity can also increase the rate of respiratory infections. So, it is important to keep inside moisture levels to a manageable level. One of the easiest and most effective methods is using a dehumidifier. These appliances take the extra water out of the air, making your home more comfortable and making it much harder for mold, mildew, and dust mites to thrive.

70-Pint vs. 50-Pint Dehumidifiers

Dehumidifiers come in all shapes and sizes, like 30, 50, or 70 pints. Most customers compare the pros and cons of 50 and 70 pints, so we focus on the differences between these two sizes below.

First, it is important to understand that 50 or 70 pints is not how much water the dehumidifier holds but how much it removes during one cycle. So, a 50-pint dehumidifier can take 50 pints of water from the area it covers per cycle.


A 70-pint dehumidifier model can remove 70 pints of water from an area over one cycle. Because 70-pint dehumidifiers are designed to take more moisture from the air, they usually are more powerful (and faster) than a 50-pint model. Due to this higher efficiency, you may not need to have a 70-pint unit run as long as a 50-pint unit.

Energy Consumption

The math of comparing energy consumption between a 50 and 70-pint dehumidifier can get tricky. Since a 70-pint unit may run less time than a 50-pint unit, it may consume less energy. On the other hand, since it works quicker, it actually uses more energy. Accurate comparisons come down to how specific models are designed and the amount of moisture they are dealing with. Most units are designed to be as efficient as possible with various functions, including automatic shut off modes and varied setting levels.

If you place a 50-pint model in an equally sized large room as a 70-pint model with equal moisture levels, the 70-pint will finish removing the moisture first. But if you put a 50-pint and 70-pint in equally sized small rooms, the 70-pint unit would waste more energy lowering the humidity.


In general, 70-pint models are more expensive than 50-pint models. This makes sense as they are larger and usually come with more modes and setting options. However, the price can vary greatly depending on the brand and its level of use.

Built-In Pump vs. Condensate Pump

70-pint dehumidifiers can be generally divided into two types. Those with built-in pumps are designed to constantly draw moisture from the area. These need to be located close to a vent or drain so the water has a place to go. If the outlet is simply exposed to the room, the water vapor that has been removed will re-enter the air in the room.

Dehumidifiers without built-in pumps work via condensation collection. These types have a collection bucket that collects the moisture as liquid water. They have to be emptied every so often to avoid overflowing. Many of these types of dehumidifiers have the option of attaching a gravity-fed hose which can constantly drain the collection bucket.

Isn’t It Easier with a Built-In Pump?

Why not just pick a dehumidifier with a built-in pump? It’s true that a built-in pump will keep you from having to empty your unit. But these models are usually more expensive and not as energy efficient as a unit without a pump. Plus, since there are more moving parts, they are not as reliable as non-pump models.

Finding the Best 70-Pint Dehumidifier for You

Finding the right appliance can be daunting. So, we have put together a comprehensive guide to help you discover which 70-pint dehumidifier is right for meeting your needs.


Getting the right size model is the first crucial step. Since we know we need a 70-pint unit, we can focus on those for now. But 70-pint dehumidifiers come in different sizes. Most units can be pretty bulky, but you can find smaller, more compact models. You need to consider where you will place the dehumidifier and if a specific unit will fit there. Another consideration is how well a unit will blend in with the decor. A model destined for the living room will probably be different than one you’d want for your basement.


Due to the large size of most 70-pint dehumidifiers, picking them up can be hard. So most, but not all, come with wheels. Depending on your ability, you will want to look for these models. If you are able, you can probably use the handles that come on most models as well.


Many newer dehumidifier models come with a number of features designed for convenience and safety. Here are some of the more common ones you will encounter:

Humidistat or hydrostat: This type of sensor measures the relative humidity in a room. This sensor then tells the unit to adjust fan speed or condenser temperature. These are great features since they let you set the exact humidity level.

Auto-restart: If you happen to lose power, this feature allows your dehumidifier to remember your settings and restore them when the power comes back on.

Auto-shutoff: When the reservoir gets too full, it can overflow if you don’t empty it in time. The auto-shutoff feature turns the dehumidifier off until you can empty the tank.

Full tank alert: Since the design of most dehumidifiers keeps you from seeing how much water is in the tank, this feature lets you know how much water you have and when the tank needs to be emptied.

Clean filter alert: Dehumidifiers have filters that trap large dust particles and other pollutants that could clog the part of the unit that removes the water. These filters need to be cleared periodically so you can keep your dehumidifier running efficiently. Some units come with a clean filter indicator which tells you when it’s time to clean the filter.

Defrost: The heart of a dehumidifier are the coils that cool the air, causing moisture to condense. Sometimes these coils can freeze due to a clogged air filter or low coolant levels. If they do freeze, it can destroy your unit. Operating a dehumidifier in cold areas can also cause these coils to freeze up. A defrost function can quickly melt the ice forming on the coils, preventing this. Not many units have this feature

Ease of Use

Some units are easier to use than others. Many come with LED displays which can be great for seeing information. But some can be overly complex to operate. Make sure you take this into account before purchasing a unit.

Emptying the reservoir on a unit can also be easier on some units than others. Pulling out a tank can cause spills, or it can be hard to reinsert the tank when it’s empty. If you can, try out a floor model before buying one to take home.

While you are at it, check to see how easy it is to remove and replace the dehumidifier filter. Most units make this pretty easy to do.

Reservoir Capacity

How much water your dehumidifier can hold is also an important factor. How often you have to empty it makes a big difference on ease of use. A common size is usually around 1.5 gallons, with bigger units having up to a 2.5-gallon capacity.

Maintaining a 70-Pint Dehumidifier

Like any appliance, a dehumidifier requires a little work to keep it functioning effectively. Ironically, these devices can become homes for mold and mildew even as they work to keep mold from growing in your house. Dehumidifiers should be cleaned regularly, including the water bucket. This can be done with normal dish soap. The filter will need to be either cleaned (if reusable) or replaced with a new one.

Keep in Mind

Always follow the manufacturer’s instructions to clean filters correctly. Trying to wash and use a non-reusable filter again can damage your dehumidifier. A washable filter must be completely dry before replacing it into the unit.


Will a Dehumidifier Remove Mold?

No, a dehumidifier can’t kill or get rid of mold or mildew. Still, it can limit or even prevent further growth by keeping the environment ‘unfriendly’ for mold.

The Center for Disease Control recommends you keep the humidity in your home lower than 50 percent to keep mold at a minimum. Most dehumidifiers can reduce moisture to humidity levels between 30 and 40 percent.

Take Note

If you have mold or mildew in your home, you need a professional’s help to remove it. Lowering the humidity in your home can slow or even stop the growth of mold. Unfortunately, it can also cause mold to launch spores into the air in search of a better place to grow. Mold causes serious respiratory problems, so anything you can do to reduce it is important.

Where Should I Place My Dehumidifier?

You can place a dehumidifier anywhere in your home that has high humidity. Many folks buy a dehumidifier for their basement, but others use them in living spaces.

Creating a Comfortable Living

If you live in a humid climate, dehumidifiers can really make your home more comfortable and safer. High indoor moisture levels can lead to respiratory problems from mold and mildew growth. By lowering the humidity, you reduce the environment in which mildew and mold thrive, increase your comfort level, and make your air conditioning more effective.

There are many 70-pint dehumidifiers on the market, so selecting the right one for you can be tricky. By considering the characteristics we’ve discussed above, you can rest assured that you will find the model that will work best for your needs.
