What is a dehumidifier?
On the contrary, we can use a dehumidifier to remove excess moisture from the air, but a humidifier can increase humidity in your room. If the humidity level is very high in your room, it will cause many problems, like mold and mildew damage to your furniture or other things, personal belongings damage, alleviating allergy symptoms etc. And such a dehumidifier can reduce the humidity, avoiding these problems.
On the market, there are so many dehumidifiers and we’ve done a lot of research and made this list of top 5 best dehumidifier, based on their ease of use features, convenient drainage features, portability, versatility, etc. Different models have different abilities to remove different amount of moisture per day.

Dehumidifier Buying Guide
High humidity levels can cause the air inside the house to become stale and stuffy, and water vapor starts to form on pipes and windows. There are numerous activities that cause moisture to form in the air. These include cooking, showering, and using the dishwasher and washing machine. This situation is problematic, particularly in locations with high humidity levels.
It is important to make sure humidity inside a house is balanced to ensure the comfort and health of the family, and the house in general. Problems can emerge when water vapor or humidity levels go up or down too much. This article gives you information in handling both high and low humidity as well as what to look for when you are looking for a dehumidifier.
Dealing with High Humidity
High humidity causes problems during winter and summer. When the air is too humid during winter, condensation forms on the inner part of windows. This causes mold and mildew to form. While molds and mildew are not serious problems, condensation may form on its interior area if the exterior walls have no vapor retarder. When this happens, the structure may become rotten and destroy insulation. This situation usually results to paint cracking, peeling, and breaking along the sides, particularly in visible areas.
Indoor humidity monitors check humidity levels inside a structure
A room becomes unpleasant during the summer when humidity levels are high. Humid air in the room slows down evaporation of moisture on your skin, and makes it feel sticky and hot. A room humidity monitor, as shown above, can measure humidity levels in a room. It normally costs less than $10.
Bathroom and kitchen exhaust fans also can help lower humidity to a suitable level. Making sure the clothes dryer is vented properly can also help. Just make sure a gas dryer is located outside. Short showers and running a full load on a dishwasher or washing machine can also help. You can also take out leaks and standing water inside the basement. But, if all of these do not help in lowering humidity levels, you should look for other methods, like using machines.
Using an air conditioner can help lower humidity levels during hot summer days when indoor humidity becomes uncomfortable. But, you should use a dehumidifier if you do not have an air conditioner or it is too cold to use it.
Selecting the Best Dehumidifier
Using dehumidifiers is the easiest and most practical way of lowering humidity levels. Dehumidifiers are simple machines designed to remove extra moisture in the air to make a room comfortable enough to stay in.
You have to consider the size of the dehumidifier if you decide to buy one. A centralized whole house dehumidifier works best for recurring high humidity issues since it uses the heating and cooling system of the house to lower humidity. But, if high humidity issues are intermittent and limited to a specific place in the house, like your basement, you can use a portable dehumidifier and bring it to the problem area.
Once you selected the unit size, you have to decide on the technology used since dehumidifiers work based on the following principles.
Houses experiencing sporadic humidity problems limited to certain areas require portable dehumidifiers that can be plugged anywhere. You can find these in hardware stores as well as home improvement centers. These dehumidifiers are user-friendly, inexpensive, and can effectively improve air quality in the house due to developments in technology. It is important to select the most effective and cost-effective unit in reducing and maintaining humidity to a tolerable level.
There are some differences in the types of portable dehumidifiers. You can consider the following when selecting one for your home.
Mini-dehumidifiers can lower humidity in small areas, like cabinets. They use silica that can renew whenever it is plugged in. These are priced at under $20
Size of the Dehumidifier
Look for a dehumidifier that is suitable for the space it will be used in. Check the area of the room you want to use the device and get an overview of the moisture level to know the proper unit size to get. The number of pints of water removed from the air within 24 hours is equivalent to the drying capacity of dehumidifiers.
The Association of Home Appliance Manufacturers (AHAM) established standards on the size of dehumidifiers for use inside houses. Many manufacturers provide simple sizing charts with each humidifier to guide homeowners on the proper unit size they need. You can also ask for the AHAM Selection Guide if the unit you want does not have a sizing chart.
High capacity dehumidifiers are better than buying units that are too small to function properly. If the unit is too small, it will not reduce humidity levels even if it runs continuously. High capacity dehumidifiers can be used in areas with too much moisture coming from dishwashers or clothes dryers that increase moisture levels. Indoor humidity levels also increase when it is humid outside. High capacity dehumidifiers are also ideal for regions with high humidity levels.
You can also select humidifiers with automated controls that monitor and regulate relative humidity levels. The best relative humidity in homes should be from 40% to 50% during the summer and from 30% to 50% during the winter. Built-in hygrometers determine relative humidity and show it on a display. You can also set a specific humidity level on the adjustable humidistat and the unit automatically maintains it.
You can also buy a hygrometer and put it close to the dehumidifier if the unit does not have one. These devices are priced between $10 and $60. You will know when to turn it off and on since it measures humidity inside the house.
You should also look into the bucket size of the unit. Large drip pans on dehumidifiers require less maintenance, but it may also require extra costs. The basic idea is the more moisture a dehumidifier extracts, the higher its price. Look around and find the best deal. A 25-pint dehumidifier may cost around $140 while 70-pint dehumidifiers cost around $225. Front-loading buckets on dehumidifiers are easier to drain.
Heat pump dehumidifiers can also be used as air conditioners.
Many portable dehumidifiers have self-draining features and have drain-hose connections. But, these should be placed in areas where water can be easily drained out of the unit, like the sink of a laundry room or floor drain in the basement. A number of dehumidifiers, like the Honeywell model, feature an evaporation technology that does not require a drain hose. These units are capable of removing around 95 pints of water each day. They also feature the heat pump technology allowing them to be used as air conditioners and use less energy.
Look for dehumidifiers capable of running at low temperatures. You should also look for units featuring an automatic defrost function unless you live in a relatively warm region throughout the year. The heat-exchange coils of dehumidifiers can ice up when temperatures inside go below 60 to 65 degrees, which makes it important to get units with a 40 to 45-degree Energy Star certification. While an automatic defrost feature may add to the price, you will not have to worry about having to frequently replace damaged heat coils.
If the dehumidifier is located close to a bedroom, noise can be an issue. Dehumidifiers featuring two-speed fans operate silently when humidity levels are low. It also reduces energy expenses. You should check the noise level of the unit before you buy it.
Casters allow you to easily move your dehumidifier from one room to another. Long power cords also allow you to position the unit anywhere.
The dehumidifier will automatically shut off when the tub is full due to its overflow protection valve. This is one feature you should look for in the unit. Some models feature indicator lights warning you when the bucket needs to be emptied.
Energy Star labels on dehumidifiers give an indication that you can save on electric bills. These government-sponsored labels show the dehumidifier is a cost-effective unit that functions properly while using less energy.
The filters on some models protect the coils against grime and dirt. Check if the filters are easily removable and washable, which you should do at least once every two weeks. This allows you to avoid replacing the filters often.
Whole House Dehumidifiers
Dehumidifiers designed for the whole house are costly. They normally cost from $1,000 to $2,000 or more. These are normally fixed units that have to be installed and connected by professionals into the duct-work of the central cooling or heating system of the house. These are normally located at the air-handling cabinet or the furnace. But, there are also freestanding models that may not be connected into the system.
