Best Dehumidifier for a Large House [Comparison of Top 5 Picks]

Best Dehumidifier for a Large House

High humidity causes asthma and allergies, among other health problems, due to dust mites, mold, and other factors. Low humidity is quite unpleasant, so maintaining a balance is critical. By installing a dehumidifier, you may achieve the optimal balance for a comfortable home.

If your house is sticky, clammy, dank, humid, wet, and moist, then you need a  dehumidifier. The drying capacity of this machine will not only make a place more pleasant but prevent possible health issues due to too much moisture in the air.

A humidity level above 50% can attract mildew, dust mites, and mold, thus triggering allergies or other medical conditions.

A dehumidifier utilizes a fan to circulate air in a room over refrigerated coils, eliminating moisture and storing it in a tank.

Dehumidifier manufacturers claim that their products remove a certain amount of pints of water from the air. Some models we examined came with a high humidity level, use less energy, or have a larger tank, which means you do not have to empty it frequently.

Why Do You Need A Dehumidifier For Large House?

The dehumidifier lives true to its name by removing humidity from the surrounding environment, and there is a lot to learn about them.

A dehumidifier eliminates moisture from the air and uses different ways to reduce and maintain a specified humidity level in an area.

There are various advantages of dehumidifying your home, crawl space, or basement, which include:

  • Mold and mildew removal
  • Eliminating allergens in the air
  • By making the environment inconducive to pests
  • Eliminates musty odors
  • Reducing humidity for a more comfortable environment
  • Safeguards your home and furnishings
  • Reducing the amount of energy used by the air conditioner or heater.
  • Aids in the treatment of breathing disorders such as COPD and asthma.

If humidity is a challenge in your house, you need this as an essential component. However, some dehumidifiers are not suitable for large apartments.

Area coverage is vital in determining whether or not a dehumidifier may be perfect for a large house. It is better to install a whole-house dehumidifier to the HVAC system, to remove moisture from the entire apartment at once.

So, how does a dehumidifier offer these advantages? The unit simply removes moisture through desiccant or refrigeration.

If you have observed moisture on the body of a cold beverage, the refrigeration process works similarly.

Dri-Eaz LGR 7000xli Dehumidifier User Guide

This section contains guidelines for the successful operation of the Dri-Eaz LGR 7000XLi dehumidifier.

You can remove excess moisture and dry wet areas like the professionals with the Dri-Eaz 7000XLi dehumidifier.

It is a top-quality and contractor-grade dehumidifier, preferred by water restoration experts for its rugged build and high performance. It removes up to 29 gallons of water per day and could dry out damp spaces up to 6500 cubic feet.

If drying after a leak or flood, start by removing as much standing water as possible. Place it in a wet area and be sure not to block the air inlet and outlets.

Remove the power cord from the pocket on the inside of the unit. Attach the power plug to the power socket on the back, then insert the prong plug into a grounded outlet on a 15 amp circuit.

Next, remove the clear drainage hose in the other side pocket and touch the quick connect end securely to the drain outlet tube on the back of the unit.

Unwind the hose and put the open end securely into a sink tub or any place where water could safely drain with less than 20 feet above the machine. Make sure the hose has no kinks and does not obstruct water.

Condensate from the air pumps out automatically, so there is no water receptacle to empty. To turn ON the unit, press the keypad on/off button and use the menu buttons to scroll through performance and set up information to reset and purge the pump.

If you are drying a damp area quickly, use the arrow key to turn off the humidistat so that the machine is operating at maximum capacity. You can also use this dehumidifier for continuous humidity control and areas up to 26,000 cubic feet.

Turn ON the humidistat and press the arrow key to set the preferred relative humidity. Check the inlet and outlet ratings displayed on the control panel. The outlet ratings should show higher temperatures and lower humidity percentages than the inlet.

If the inlet temperature is at or below 60 degrees Fahrenheit, consider adding heat to promote proper drying.

Once the drying is complete, turn the dehumidifier off but do not unplug it yet because the unit will go through a shutdown process to dry the internal coils, then finish it with a purge of the pump.

Once complete, disconnect the power and drain hose. Roll and place them back in the side pockets. Always use a Dri-Eaz dehumidifier with a Dri-Eaz air mover for faster and more efficient drying.

The air mover promotes evaporation from wet materials, and the dehumidifier removes the moisture from the air to allow materials to truly dry.

How To Select The Best Dehumidifier For A Large House?

If you have recurring issues with high humidity, then consider a central whole-house dehumidifier, which uses your home’s HVAC systems to reduce humidity in the entire house.

However, if high humidity is only present in specific areas of your house, such as a basement, a compact dehumidifier that serves that purpose will work just fine.

After deciding on the size of the unit, you must choose a technology—dehumidifiers remove moisture from the air using one of several concepts.

1. Portability

Portable dehumidifiers, which you simply plugin, are the most popular models for large homes with only occasional, localized moisture issues. You can easily find them in big box hardware stores and home improvement hubs.

With technological advancements, these dehumidifiers are convenient to use, inexpensive, and effective at improving the air quality in a home. The goal is to select an effective and efficient unit that reduces indoor humidity and maintains it at optimal levels.

The most portable dehumidifier in this list is the Aprilaire 1870XL.

2. Dehumidifier Size

Choose a dehumidifier suitable for the area to be used. To get the correct sized dehumidifier, you should know the coverage area of the house you want to dehumidify and have an idea of the moisture levels in the area.

The pint of water removed from the air in 24-hours determine its drying capacity.

Smaller units may operate continuously without reducing the humidity to an acceptable standard.

Higher capacity humidifiers can also handle spaces that may be excessively damp due to the addition of moisture to the air by clothes dryers or dishwashers.

Furthermore, if the outdoor climate is warm and moist, the indoor humidity level will increase. If you live in a humid climate environment, you may want to choose a dehumidifier with a higher capacity to handle the humidity in your entire house.

Considering the size, the Dri-Eaz LGR 7000XLi dehumidifier is the best option.

3. Humidity Control

Go for a humidifier with automated control mechanisms for monitoring and adjusting the relative humidity levels.

The ideal humidity levels in a home should be between 40% and 50% in the summer and 30% to 50% in the winter. Humidity-controlled units with built-in hygrometers measure and display relative humidity.

An adjustable humidistat allows you to set your preferred humidity, and the unit will maintain it automatically.

If the unit you choose does not have these settings, you should consider purchasing a humidity sensor to hang next to the dehumidifier. This humidity sensor will measure the indoor humidity, so you know when to turn on and off the unit.

All the dehumidifiers listed in this review come with a humidistat for regulating humidity levels.

4. Water Capacity

Consider the bucket size of the unit. Dehumidifiers with large tubs or drip containers require less frequent emptying.

However, you should expect to pay more for the convenience because dehumidifiers that extract and hold more water are expensive.

Most portable dehumidifiers are self-draining and include a drain hose connection, but the location must be close to where the hose can empty water into a laundry room sink or a basement floor drain.

Some dehumidifiers use evaporation technology to empty the water and eliminate the need for a drain hose. They use heat pump technology as an energy saver and air conditioner. It is best to consider units with a continuous drain function.

The Dri-Eaz LGR 7000XLi and Aprilaire 1870XL dehumidifiers offer the best water capacity.

5. Automatic Defrost Feature

Choose a unit that operates at low temperatures. Unless you live in a warm climate at all times, consider the one with an automatic defrost feature.

When indoor temperatures fall below 65 to 600F, the heat-exchange coils on a dehumidifier can frost over. So look for a unit with an Energy Star rating of 45 to 40 degrees.

Although the automatic defrost features may be expensive, they will save you the cost of replacing a unit damaged by iced coils.

The Colzer 140-pint and Kesnos 70-pints outperform with this feature.

6. Automatic Power Off

When the container is almost overflowing, an overflow protection valve will switch OFF the unit. The automatic power-off feature is a must-have on any model you select. Some units have an indicator light to signal when the bucket is full.

The Colzer 140-pint, Tosot 70-pint, and Kesnos 70-pint dehumidifiers come with the auto shut-off feature to prevent overflow since they drain in containers.  

7. Energy Conservation

Dehumidifiers with the Energy Star label will help you save money on your utility bills. Government-certified dehumidifiers are guaranteed to use less energy while operating efficiently.

Tosot 70-pint has the Energy Star label and uses less energy.

Final Words:

Moist air is a haven for mold, mildew, and allergens. Dehumidifiers remove moisture from the air, keeping you comfortable and healthy while safeguarding your home from harmful growths. You should use a dehumidifier if the air in your home feels sticky or if you notice moisture on the insides of your windows.

When purchasing a dehumidifier for a large house, go for the best model you can afford. Smaller models may be able to handle the job depending on the size of the space. Larger models are faster, more efficient, and dependable.

To handle the water extracted from the air, you can attach a hose to a continuous or direct drain dehumidifier and let gravity pull the water toward a drain. If you intend to use a drain above your dehumidifier, look for a model with a built-in pump, or go for the one with a collection tank so you can empty it manually.
