Choosing Your Best Dehumidifier Smartly

Dehumidifier helps to normalize the humidity levels in your home to prevent allergens (dust mites, mold, and mildew), reduce irritation to your skin and respiratory system so you can breathe easier and feel comfortable in your home.

And since the level of humidity in your home are at normal levels, then your clothes, furniture, and other linens are free from mold growth.

Using dehumidifier also helps your window air conditioner to run more efficiently since it doesn`t need to work too hard in cooling the air and removing moisture. [1]

However, even if you need it so desperately, never buy one blindly.

To get the right unit that fit to your dehumidifying needs, proper knowledge is required.


Choosing Your Best Dehumidifier

1. Size & Capacity
A capacity of a dehumidifier is rated in pints of moisture removed per day. So, if you see a "10-pint dehumidifier", then that unit will remove 10 pints of moisture per day.

According to the Association of Home Appliance Manufacturers (AHAM) [2]

Condition Without Dehumidifier 500 Sq. Ft. 1,000 Sq. Ft. 1,500 Sq. Ft. 2,000 Sq. Ft. 2,500 Sq. Ft.
Moderate Damp with Musty Odors in Humid Weather 10 pints 14 pints 18 pints 22 pints 26 pints
Very Damp with Odors and Damp Spots on Walls and Floors 12 pints 17 pints 22 pints 27 pints 32 pints
Very Wet with Sweating Walls and/or Seepage 14 pints 20 pints 26 pints 32 pints 38 pints
Extremely Wet with Wet Floors and High-Load Conditions 16 pints 23 pints 30 pints 37 pints 44 pints

Another measurement that can determine the size of dehumidifier you need is the amount of air the appliance can move measured in "Cubic Feet per Minute or CFM".

First, you need to know the humidity level in your room (you can use hygrometer).

The level of moisture in the air tells you how many times the air in your room should cycle through the dehumidifier every hour. This is known as Air Changes per Hour, or ACH.

The level of moisture in the air tells you how many times the air in your room should cycle through the dehumidifier every hour (known as Air Changes per Hour or ACH).

The higher the humidity level in your room then the higher ACH needed.
• 60-70% - Recommended ACH = 3
• 70-80% - Recommended ACH = 4
• 80-90% - Recommended ACH = 5
• 90-100% - Recommended ACH = 6

While to calculate the CFM, simply multiply the cubic feet of your room by the recommended ACH, and then divide that number by 60 minutes. [3]

2. Type
Compressor Dehumidifiers - very energy efficient, but it won't operate below 3 deg C 38F and don’t perform well at low temperatures (below 10C 50F).

However, it is very rare to have temperature in a home of 10 C 50F.

Desiccant Dehumidifiers - mainly used in commercial applications where temperatures are low less than 10c 50f. or when a very low RH is required.

3. Other Features To Consider:
• An internal pump automatically pumps water vertically to a water basin for continuous operation.
• A direct drain allows for continuous operation with a gravity feed to a floor-level drain.
• A filter indicator shows when the air filter needs to be cleaned.
• An auto humidistat senses moisture level in the area around the unit and automatically shuts the unit off to save energy once the desired humidity level is attained.
• A low temperature setting allows units to operate in temperatures as low as 41°F.
• Auto-defrost keeps units from freezing in colder environments below 65°F.
• Auto reset will restart the unit to its previous setting in case of a power loss.
• ENERGY STAR certified unit for efficient energy. [5]
• Automatic shutoff and auto restart.
• Washable filters.
