Dehumidifier Ratings and Reviews to help you choose



How do I Choose My Dehumidifier?

How do you know which the dehumidifier to buy? You've got to ask yourself a few questions. One thing you’ll probably be wanting to look for is a high efficiency factor rating. The so-called Energy Star ratings can save you some money in the long run. A very desirable feature in a dehumidifier is the frost free option. Also, the good the dehumidifiers have a built-in humidistat and shut off feature.

You will have to consider the size of the unit that you need before purchasing. Here's a chart to help you determine your needs based on your square footage:

Association of Home Appliance Manufacturers (AHAM) Dehumidification Selection Guide

Values in table indicate dehumidification required in Pints per 24 hours, based on the area of the space to be dehumidified and the conditions that would exist in that space when a dehumidifier isn't in use.

Air comfort level of the living space before dehumidifying during warm & humid outdoor conditions.

  Area -- Square Feet

Moderately damp - Space feels damp and has musty odor only in humid weather.






Very damp - Space always feels damp and has musty odor.
Damp spots show on walls and floor.






Wet - Space feels and smells wet. Walls or floor sweat, or
seepage is present.






Extremely wet - Laundry drying, wet floor, high load conditions.






Dehumidification variables also include such other factors as climate, laundry equipment, number of family members, number of doors and windows, and degree and intensity of area activity.(Source: Association of Home Appliance Manufacturers -

Here's a much condensed and easier to read chart, but still very relevant:

Moisture in Pints per day

Sq. Ft Damp Wet
500 12 14
1000 16 18
1500 20 24
2000 24 30
2500 30 36
3000 36 44

So for example, if the area you wish to dehumidify was 2000 square feet, and was moderately damp but not wet, you would choose a dehumidifier which could remove 24 pints of water per day, from the air.

Having casters on your dehumidifier can turn out to be very handy when you want to move the unit to a different room or a different spot in the basement. Also a dehumidifier that would have a capacity of around 60 pints, would weigh about 55 pounds.  Otherwise, a portable dehumidifier may be best for you.

You want to make sure your dehumidifier has a air filter that is removable and washable.

Also consider these questions when choosing your machine from the long list of dehumidifiers for home available on Amazon:

  • Is it big enough? Units that are too small can let humidity get out of control and usually have higher operating cost.
  • Is it certified as an Energy Star model?
  • Does it have a high Efficiency Factor?
  • Does it have a long warranty period?
  • Can you get local service if needed?
  • Does it have a frost-free feature?
  • Does it reset to your preset conditions after a power interruption?
  • Can you drain it into a sump, laundry tub or floor drain, etc.?

Use this checklist to determine your own needs.
