Things to Consider
As promised, we are going to break down the essential features of the best 70-pint dehumidifier, provide you with tips on how to take care of your dehumidifier, and answer some of the most common questions.
Tips on how to maintain a 70-pint dehumidifier
Use the humidistat which automatically detects current humidity levels and adjusts it to the programmed one, then switches off the unit once the desired level has been reached. This is a convenient way to save energy and prevent overhumidification or underhumidification.
Filters keep our air clean and trap harmful particles from the air. To prevent clogging of the dehumidifier by buildup of debris, you should clean the filter whenever the filter alert goes off, or according to the timeframe recommended by the manufacturer.
Wash the water tank periodically with soap and a disinfectant to prevent mold and mildew from breeding and causing respiratory infections. Consult your manual for the ideal timeframe.
Check for blockage in the air intake and exhaust to prevent obstruction of air circulation.
Ensure there are at least six inches around the 70-pint dehumidifier for free air flow. If possible, shut the windows to avoid overworking the dehumidifier.
Keep the dehumidifier away from taps and spilled water to prevent accidental shock.
Features to consider while choosing a 70-pint dehumidifier
A 70-pint dehumidifier is designed for large areas which require a high moisture removal rate. The stakes are higher than when shopping for a model designed for a small room. This is why it is necessary to get it right. The following features will guide you on how to do it.
This refers to the amount of space in square footage that the dehumidifier can adequately remove moisture from the air. Since dehumidifiers are designed to cover specific sizes, knowing its coverage area prevents you from wasting your money on a unit designed for smaller spaces will not work effectively in a large area. Manufacturers indicate the designated coverage area for their models. Like the powerful, heavy-duty whole house dehumidifiers, most of the models in our list can cover up to 4,500 square feet. In case your home is of a bit smaller size, consider getting a 50-pint dehumidifier. If, however, the area you need to dehumidify is much larger, probably you need a commercial dehumidifier that can cover around 7,000 square feet.
A number of models, such as Frigidaire FFAP7033T1 and Ivation 70 Pint Energy Star Dehumidifier have built-in pumps which provide more draining options like uphill drainage which is not possible with gravity-reliant drainage. This is convenient in basements and other areas with high moisture levels because it can remove large amounts of moisture without the risk of water overflowing and without the need to mount in on an elevated surface. Simply attach a hose to drain into an external drainage and let the pump do the rest of the work.
Water tank capacity
Almost all dehumidifiers include a water tank where the removed moisture is collected. A tank with a high capacity can hold more water over a long period of time which reduces the frequent need for emptying. With the exception of Ivation 70 Pint Energy Star Dehumidifier with Pump which can hold 1.3 gallons, the rest of the dehumidifiers in our list feature water tanks with a capacity of 1.6 gallons which is convenient in large areas. The reservoirs can be easily removed for emptying, with some having handles.
Moisture removal rate
This refers to the amount of moisture that a specific dehumidifier can remove from the atmosphere in a period of 24 hours. The models in our list remove 70 pints of moisture in a day.
Large areas and rooms with high moisture levels require dehumidifier with a high rate to effectively regulate the air to ideal humidity levels. The high moisture removal rate also saves energy because it takes less time to achieve optimal levels.
Fans draw air into the dehumidifier where moisture is removed. Look for a model with multiple speed and modes like turbo and eco-mode which allow you to select the right setting for your dehumidification needs and save energy. Low fan speed is also known to reduce the amount of noise output.
Continuous drain option
Dehumidifiers include a drainage option, with drain hose attachment being the most common for continuous drainage option. This eliminates the need for regular removal of the collected moisture which is ideal for low maintenance. The drain hose is attached to the unit and placed on a lower level to use gravity for drainage. Other models have pumps integrated in the unit to automatically drain water at any level, including uphill.
Dimensions and weight
The size of a dehumidifier normally matches the amount of square footage in which it can effectively reduce moisture level. This makes units designed for large areas bigger and heavier.
The right weight and dimensions will depend on the amount of space available for its storage and whether you will set it up in one place permanently or use it in different rooms. Majority of the models will include caster wheels and handles for smooth mobility.
Since dehumidifiers use fans to draw air into the unit, they can be noisy, with the level varying from one model to another, and from one speed setting to another. The level of noise is measured in decibels. The average noise output of dehumidifiers is 40 to 50 decibels at a high-speed setting, which is equivalent to the sound made by a refrigerator. Frigidaire FFAP7033T1 produces 51 decibels on high speed while Danby DDR070BDWDB operates at 50 decibels.
Energy Star certification
Dehumidifiers with this certification have efficient coils and fans which are designed to consume 15% less energy than models that do not bear this certification. Look for this certification when shopping for the best 70-pint dehumidifier to save more on energy bills.
Consider the warranty duration of your intended purchase, availability of replacement parts and situations that could void your warranty.
Washable air filter: Air filters remove particles from the air and prevent clogging of the dehumidifier. Since 70-pint dehumidifiers cover large areas which can cause buildup of debris and inhibit performance, it is essential to choose a filter that can be washed and reused to reduce replacement costs.
Built-in humidistat: It detects the current humidity level and automatically adjusts it to the designated one. This saves energy since it only operates when required.
LED/LCD indicators: These alerts go off to notify you when the tank is full and when the filter is due for cleaning.
Electronic controls: Some units have knobs and dials while others have a digital display with a touchscreen interface. Electronic controls display the current settings and allow you to set your preferred humidity levels.
Timer: This is used to schedule the 70-pint dehumidifier to turn on or switch off at a specified time.
Auto-restart: It switches on the unit automatically and restores the programmed settings after a power outage.
Auto-defrost: Defrost sensors prevent the coils from freezing from ice buildup in low temperatures.
Auto shut-off: It switches the unit off automatically when the desired humidity level has been achieved to save energy, or when the tank is full to prevent the collected moisture from overflowing.
Handles and caster wheels: They improve mobility and portability.
You can never go wrong with a unit designed for larger spaces. It is actually recommended to go for a higher capacity. A 70-pint dehumidifier will effectively remove moisture in a small room in a shorter time which will also save energy. However, you should opt for a smaller model with a lower dehumidification rate if you are on a budget and not intending to use it in.
Frequency of emptying the water tank depends on the size of the tank and the availability of continuous drainage option. The larger the tank capacity, the fewer times you need to empty it. On the other hand, continuous drainage option eliminates the need to empty the tank which works well in case you are forgetful.
Although pump models consume more power than non-pump models, they are actually more energy-efficient because they use far much less time to remove the same amount of moisture as non-pump models. Non-pump dehumidifiers consume less power but operate for a longer period which racks up energy bills. Look for a model with Energy Star certification if you’re concerned about excessive energy consumption.
Frigidaire FFAP7033T1 was a clear winner because it blends all the features that make a dehumidifier effective for large rooms and basements such as a built-in pump for continuous drainage, automatic defrost to prevent ice buildup while it works at temperatures as low as 41°F, and a high 1.6-gallon water tank capacity which matches the high moisture removal rate of 70 pints in 24 hours.
Danby DDR070BDWDB covers a wide area of up to 4,500 square feet and features a user-friendly touchscreen interface with a programmable timer, an auto/manual button, an automatic restart feature, and adjustable fan speed. This allows you to customize the settings to your liking.
