Most dehumidifiers should not be operated in temperatures below 60° F, since the moisture removed from the indoor air can freeze when it condenses on the cooling coils, which can damage the unit.
What is the lowest temperature a dehumidifier will work?
Ordinarily, a dehumidifier will not operate satisfactorily at temperatures below 41 degrees Fahrenheit or under extremely low humidity conditions. At temperatures below 41 degrees the evaporator coils may freeze. This could make it necessary to defrost the coils as often as once per hour.

Set the humidity level. The optimal relative humidity level is between 30 and 50 percent, according to Energy Star (and 30 to 40 percent in colder areas during heating season). If the humidity is higher than that, it can breed dust mites, mildew, and mold, and trigger allergies.
What's a desiccant dehumidifier?
A desiccant dehumidifier has no compressor and does not use a cold surface to extract the excess moisture from the air. Instead it has a desiccant wheel that absorbs the moisture from the air, in a similar way to a sponge.
Can you run a dehumidifier in an unheated garage?
If your garage is unheated then you will need to choose a dehumidifier that will continue to work at cooler temperatures. This means that you will need either a compressor powered dehumidifier that has hot gas defrost or a desiccant unit that will work irrespective of the temperature.
Do dehumidifiers work at 55 degrees?

A dehumidifier is the most direct way to deal with humidity in a garage and prevent condensation and mold. It will keep moisture levels in check and reduce the moisture that mold spores require for growth as well as preventing tools from rusting and structural wood rot.
Can I use a dehumidifier in a cold room?Most portable dehumidifiers are not meant to work in cold rooms. Their user manuals typically state that the minimum operating temperature required is 65 ºF. There are some dehumidifiers that will work below this temperature. These are usually dehumidifiers with special defrost functions or desiccant dehumidifiers.
Article first time published onShould I run my basement dehumidifier in the winter?
You should only run a dehumidifier in your basement in the wintertime if the room maintains a high relative humidity. To monitor the relative humidity in your basement, hang a humidistat (sometimes called a hygrometer) on the wall. It works like a thermometer, constantly measuring the relative humidity in the room.
Should you run a dehumidifier all the time?
Should a Dehumidifier Run Constantly? No, there is no need to keep the dehumidifier running constantly. It’s generally enough to run the unit when the humidity level is 50% or higher. A good rule of thumb to remember is to maintain a comfortable 30-50% humidity level for most homes.
Will mold grow at 55 humidity?
A relative humidity greater than 55 percent is enough to support the growth of black mold. … Household problems such as water and pipe leaks cause water intrusion and an environment perfect for black mold to grow. The mold can continue to grow unabated if a small leak goes undetected for a long time.
What should I set my dehumidifier at in summer?
In the summer, humidity can cause major problems inside homes, but luckily you can help solve those if you have a dehumidifier. But at what relative humidity setting should you set your dehumidifier? You should set the relative humidity (RH) level of the dehumidifier between 30 to 50%.

What should humidity be in garage?
If you measure the humidity level with a hygrometer, it should not exceed 45 to 50% in order to keep the garage comfortable. In order to reduce the humidity level, there are two methods: you can use a dehumidifier or you can shut off the heating system and open the garage door about 30 cm for 10 to 15 minutes.
Which is better dehumidifier desiccant or refrigerant?
The Main reason to Choose a desiccant dehumidifier is that it can operate at much lower temperatures than a refrigerant type. If you are choosing a dehumidifier for a particularly cool area, such as some garages and workshops you may wish to consider this type.
Which dehumidifier is better desiccant or compressor?
Desiccant units are incredibly durable and extremely effective at extracting moisture in almost any circumstances. Whilst a desiccant unit may consume more power on an hourly basis than a compressor unit, they are much more effective at extracting moisture and achieve a better result in a much shorter time.
What is a Peltier dehumidifier?
Peltier dehumidifiers work by pulling in damp air over the front of a cold heat sink. As the air passes over the cold surface, it condenses. The water released from the condensed air then drips down into the water tank and the dry air is released back into the room.

How low can a dehumidifier get the humidity?
The air that comes out of most dehumidifiers is around 30% humidity. At 70 degrees and higher it is possible to reduce the humidity to 35% to 40%. As the temperature goes below 70 degrees and down into the 50’s this will rise to 60 %.
Do dehumidifiers work in low humidity?
Lowering Humidity with Dehumidification Dehumidification is the most effective and efficient way to lower the relative humidity of an area. … Using heating and air conditioning to control the temperature, dehumidifiers work within the climate control system to maintain proper humidification levels.
Does a dehumidifier work better in a warm room?
A dehumidifier is most effective at warmer temperatures and higher relative humidity levels. Relative humidity levels above 60% can cause mold or mildew to grow, resulting in musty smelling air and unhealthy airborne mold spores. The ideal relative humidity level should be somewhere between 30% – 50%.
When should you run a dehumidifier in the winter?
Since the purpose of a dehumidifier is to attract moisture, the coils could freeze if the weather gets too cold. However, in rooms that are above 60 degrees Fahrenheit, such as a heated basement, then a dehumidifier would work just fine. Just pay attention if the temperatures start to drop, especially at night.
Does a dehumidifier help with congestion?
Both systems help reduce ailments like chest congestion, allergies, and asthma. For example, a dehumidifier can help treat asthma that is triggered by humid air. Or, if you are suffering from a cold that has caused nasal passage blockage or sinus congestion, using a humidifier will help break that up.
When should you stop using a dehumidifier?
When you find the relative humidity (RH) going below the 30% – 50% range, you need to immediately switch off the dehumidifier. If there is too much dehumidification, say below 30%, it will result in the growth of several bacteria, mold, and dust mites that thrive in low humidity conditions.
Can I leave dehumidifier on 24 7?

How long does it take for a dehumidifier to dry out a room?
6. How long will it take to get the moisture under control? As long as the dehumidifier you choose is large enough for the area it is working in, and there are no specific damp problems, then a dehumidifier will normally reduce the humidity to the chosen level within a few days to a week.
Why does my dehumidifier run but not collect water?
Overload. If your dehumidifier is no longer pulling water from the air and you have verified that the ambient room temperature is above 65 degrees Fahrenheit, then the unit’s compressor may not be running. … A common cause for the overload to fail is from operating the dehumidifier on long or undersized extension cords.
