How Much Water Should a Dehumidifier Collect in a Day?

Water Removal

Your dehumidifier is a great way to keep your home dry and free of mold. It also keeps the air in your house healthy by removing excess humidity. When you first get it, you should be checking the water bucket every day to make sure that it's filling up. But how much water should a dehumidifier collect in a day? That depends on how humid where you live is - but there are some general guidelines for average climates.

The Short Answer

Dehumidifiers are able collect water from the air by running it through coils where condensation is created and collected in an internal reservoir. The majority of these devices can extract around 2-5 gallons per day depending on their power, ambient temperature, and the relative humidity level at which they operate most efficiently.

The higher powered models that have better cooling capabilities - like those with refrigerant or Peltier technology – will typically produce more than 13 gal/day if operated within certain parameters.

Understanding Typical Dehumidifier Performance

In order to understand the typical dehumidifier performance, you must first know that it will take time for a powerful dehumidifier to achieve an ideal level of humidity. Most models can get levels under control within 12 hours but as expected, smaller size machines are slower while larger ones typically have less wait-time.

Here in this section we’ll discuss factors affecting how much water is collected in your tank and what to do if performance isn’t up to par with expectations.

Capacity of Dehumidifiers

Dehumidifiers come in various capacities, depending on the size and needs of your home. For instance, a 10 L dehumidifier can extract up to 5 litres per day; this is more than enough for many homes that need only minimal amounts extracted each day. If you live an area with excessive humidity levels or require a larger volume extraction occasionally, then go ahead and purchase one accordingly.

Average Humidity

Humidity levels should be maintained at between 30% to 50%, which means the average humidity level of a room in your house. This will help you figure out how many pints per day need removing from excess moisture and can make it easier on yourself before extreme weather conditions set up camp outside and inside your home as well!

Air Temperature

Dehumidifiers are more effective when the air is warmer. While a few degrees won’t make much difference, it's normal to collect less water during cold weather and more in hotter months.

Living Space

Whole-house dehumidifiers can extract a lot more water from the air than room or portable ones. Whole-house units are large so they're able to remove far more moisture in one day then most room dehumidifiers, which usually only suck out around 40 to 50 pints of liquid per day if an average sized room is about 2,000 square feet.


How Quickly Should My Dehumidifier Fill Up?

Depending on the moisture levels and the humidity settings of your dehumidifiers, it will probably take about 12-13 hours for 4 liter water containers to be entirely filled with water.

Should I Open The Windows When Using a Dehumidifier?

Well, it depends on your situation. If you have higher humidity outside than inside and want to reduce indoor moisture levels, then leave them closed. Otherwise if the weather is really hot with low relative humidity or there's no air conditioning in sight - open up those widows.

Do Large Dehumidifiers Use More Electricity?

Larger machines use more water per energy, which is why the dehumidifier costs can be a bit of a burden unless you choose an energy-saving dehumidifier. The good news is, the market is flooded with several brands of advanced dehumidifier models that are energy efficient despite prolonged continuous operation.

Should I Run My Dehumidifier Non Stop?

During high humidity seasons (over 60%), keep it running all day; however, if relative humidity drops below 60%, run during daylight hours and turn off at night

Final Verdict

If you want to keep your home at a comfortable humidity level, it's important that the dehumidifier is working properly. To do this, make sure to read up on how many pints of water should be collected each day and also know about optimal levels as well as what alarms might mean if something goes wrong with the unit.
