A dehumidifier should collect a certain amount of water each day - generally, around 10-20 pints of water per 24-hour period. This should require you to empty most dehumidifiers daily or bi-daily when in operation.
If your dehumidifier's water basin is filling up too quickly, you probably have extra water in the air due to an issue like a cracked pipe, water leak or open crawl space. If you're hardly getting any water in the basin, you may need to simply turn the control to a drier setting.
Can you dehumidify too much? There is a chance of dehumidifying your home too much with a dehumidifier, especially if you are leaving your dehumidifier running for several hours on a timer unattended. Over-dehumidifying your home can lead to an increased chance of respiratory illnesses and dry and cracked skin.
It could take up to twelve hours to see your dehumidifier working, especially if you are in a particularly muggy climate. If you're using a dehumidifier to clean up after a flood or severe leak, it could take up to a week to notice a difference. Many household dehumidifiers can also fill up in a matter of hours.
All of the dehumidifiers in CR's tests have an indicator that lights up when the tank is full, and the unit shuts off automatically. You can either empty the tank yourself or connect a hose to any of the tested dehumidifiers to divert the water to a drain nearby.
Should you keep your dehumidifier running all the time? In order to achieve the ideal indoor relative humidity levels of 35 to 50 percent, it is recommended that you run a dehumidifier for 12 hours a day.
As a general rule of thumb you may need to empty your dehumidifiers bucket at intervals ranging from once every two days to twice a day, depending on the conditions.
If you're concerned about spending too much on your electricity bill, you can try calling your energy company and asking about the “best times.” Usually, the best times to run your unit, that will save you money, is between 10 pm and 7 am — this is when less people are consuming energy, which drives down the rates.
The size of the room, the humidity level, and the extent of the water damage are some of the variables that affect how long a dehumidifier takes to dry out a room. A dehumidifier typically needs between 24 and 72 hours to completely dry out a room.
How often you should use a dehumidifier will depend on your home, climate and other factors. To achieve the highest energy efficiency, run a dehumidifier for at least 12 hours a day. This will allow you to remove moisture from the air without racking up the energy costs.
Check to make sure that all windows and doors are closed. Make sure the unit has proper air flow and that no curtains, blinds, or furniture is blocking the front or back of the dehumidifier. If used in a laundry area, install the dehumidifier away from the moisture laden air generated by the dryer.
Where to Place Dehumidifier in Your House. You want to place your machine in an area where there is good air circulation so the unit can efficiently work. We do not recommend placing a dehumidifier directly against a wall or piece of furniture. Instead, put it at least six inches away from these vent-blocking surfaces.
We suggest keeping your humidity level at 45-50%. You can adjust it slightly based on your comfort level, but keep in mind this is an ideal humidity level for healthy indoor air quality. Avoid mold and mildew by keeping your humidity level at or below 50%.
Try changing your filter first. If that doesn't solve the problem, then you may need to replace the desiccant. It could also be the case that the fan is blocked, so be sure to check for and remove any obstructions that could cause the fan to stop working properly. That said, most dehumidifiers are compressor-based.
Make sure the hose is routed downward. A drain hose that bends or that has been routed to drain water uphill will not work. This drain setup relies on gravity to work correctly. Check to ensure that your drain hose is free from bends, kinks, clogs, or other damage that may prevent water from flowing freely.
Can I leave the dehumidifier running at night? Yes, we recommend using a dehumidifier 24hrs, however, be aware that there will always be a noise generated from the machine when it is operating.
Dehumidifiers work by removing moisture from the air. This can help to reduce condensation on walls and prevent mould and mildew growth. However, dehumidifiers will not necessarily dry out damp walls. If your walls are damp, you may need to use a combination of a dehumidifier and a fan to help dry them out.
Attention should be given to the placement of your unit. It should be positioned in proximity to a sump pump or drain and the hose should be placed outside of walkways to avoid a tripping hazard. Most dehumidifiers will remove between 30 and 70 pints of water per day.
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.
Although the energy consumption for small and medium-sized dehumidifiers is relatively low, long-term usage (especially older, less energy-efficient models) can add up to be quite a substantial amount. This is compounded by the fact that most dehumidifiers run 12 to 24 hours daily.
It's most common to use a dehumidifier from May through to September but depending on the climate where you live you may need one in the winter. Dehumidifiers can be useful in the winter for wetter and colder climates (such as where we live) where they can prevent condensation on windows and mold growth.
The lifetime of dehumidifiers usually ranges from five to 10 years. To maximize the lifetime, it's important to care for your dehumidifier. Be sure to regularly change the air filters, clean the condensing coils and exhaust grilles, and empty and clean the water bucket.
Simply put, dehumidifiers cannot remove mold. The machine is designed to remove moisture in the air. This means that if there is already a presence of mildew in a home or building, it will not be removed just by working to reduce the moisture after the fact.
However, many people wonder if their dehumidifier should run in the winter. The answer is that, in most cases, dehumidifiers typically do not need to run during the winter months in most areas because the air is naturally dry due to low humidity and the use of heating systems.
