Overview: Humidity is the amount of water vapor in the air. Water vapor is the gaseous state of water and is invisible. Humidity indicates the likelihood of precipitation, dew, or fog.
Source: Wikipedia of the optimal humidity level should be as close to 50% as can be economically achieved. A suitable humidifier can be used to cheaply achieve the desired humidity level.
A dehumidifier is a household appliance that reduces the level of humidity in the air as excessively humid climates or air can make us feel extremely uncomfortable, causing excessive sweating that can’t evaporate in the already-moisture-saturated air.
Saving For Dehumidifier [Today Deals]
Here are some of the important factors to consider before buying a dehumidifier:
1. What’s The Capacity Of The Dehumidifier? How Many Pints/Day?
Dehumidifier capacity is generally stated in terms of pints per day. The most popular ones on the market range from 30 pints to 70 pints per day. 70 pints is considered the upper limit for household dehumidifiers and it’s more than enough to dehumidify the air in most humid regions.
2. Is There An Auto-Drain Option?
The auto-drain option basically consists of a drain hole (most of the time at the back or side of the dehumidifier) that connects to a floor drain through a hose. This allows the dehumidifier to constantly drain the accumulated water and work without interruptions.
3. Is The Bucket Easy To Remove And Empty?
All dehumidifier models have water buckets (even those with the auto-drain option) to collect the water they draw from the air.
There are two basic things that are important here: 1- what’s the capacity of the water bucket (this one practically determines for how long the dehumidifier can work without needing the user to empty the bucket), and; 2- is the bucket easy to remove and empty (some buckets have inconvenient handles, get too heavy, etc. and cause problems).
4. Is There An Auto-Stop Function?
This is a vital option for anyone using the water bucket and not the auto-drain. This function ensures that the dehumidifier stops as soon as the bucket is full (or reaches a certain level, depending on the model). Almost all dehumidifier models have this feature, but what’s more important here is whether or not it works as intended. Because if it doesn’t, the dehumidifier will continue to work even when the bucket is full, risking a potential flood.
5. Can The Dehumidifier Work In Low Temperatures?
This may not be very important for people living in hot/warm climates, but those who live in cold and humid areas will certainly appreciate the dehumidifier’s ability to perform in extreme cold.
6. Is It Noisy Or Quiet?
The noise level is another important factor that may be crucial to some people. They may want to use the dehumidifier in their bedrooms or at their kids’ rooms and therefore want a quiet model.
7. How Simple/Complicated Are The Controls?
Cheaper dehumidifier models will have simple controls like an on/off button or a high/low setting, while more expensive models will offer humidistats, timers, etc. that will make the unit more convenient.
8. Is There A Timer?
Some dehumidifiers will have timers that allow users to set the unit to work at a specific time. This allows them to set the dehumidifier to engage while they’re away from home. However, if there is such a function, the auto-drain or auto-shutoff features must function flawlessly to prevent any disaster.
9. Is The Filter Easy To Remove And Clean?
There are two things users will have to do in terms of maintenance; the first is emptying the bucket as we have mentioned before (if they are not using the auto-drain option, and the second is to periodically remove and clean the filter. What’s important here is that the filter is conveniently placed and easy to remove and clean.
Some models have slide-out filters placed at the side or bottom. All it takes is to simply slide the filter out and wash it.
10. Is It Energy Efficient?
Running an extra electric appliance will always add to the power bills, and the consumers will want to know how big a hole this new appliance will open in their pockets. If the unit is energy-efficient, it will consume less power and have a smaller effect on the power bills.
