How Much Water Should a Dehumidifier Collect in 24 Hours? Minimum 10 Pints

If you have a problem with too much humidity at home, you will ask: How much water should a dehumidifier collect in a day?

You want to be sure that the dehumidifier you buy will dehumidify your indoor spaces appropriately.

High humidity can cause mold, and serious health effects in your body.

The good thing is that there is a dehumidifier for everyone and every need, including large, whole-house units.

So, how much water should a dehumidifier collect? For any space, get a dehumidifier that can collect 20 to 70 pints daily. This depends on the size of the unit, small, battery-powered units like Afloia Gun Safe Dehumidifier have a low capacity of 0.21 pints. A Frigidaire dehumidifier can collect up to 60 pints.

It is hard to give a blanket figure for water that a dehumidifying unit should collect daily. It depends on the size of the unit. The space rating also matters a lot.

Factors determining how much moisture a dehumidifier unit collects

A bigger unit will do a better job of drawing moisture from the air than a smaller one. Here are the main factors that determine how fast it will work:

1. Size of the dehumidifier: Bigger units collect more water

If you live in a high-humidity place like Florida, you need a high-capacity dehumidifier. If you have experienced flooding, you need a big unit.

To dehumidify a room for just a few hours a day, you need a low-capacity unit. This can be anything from 5 pints.

The main thing here is to bring the humidity level down in as short a time as possible.

A high-capacity 60-pint dehumidifier can lower the humidity level from 70 percent level to 35 percent in less than 20 minutes.

A small dehumidifier, say, a 20-pint unit, can lower the humidity from 70 percent to 35 percent in about 2 hours.

Also note that when you use a low-capacity unit, you might have to empty it more often than a bigger one.

2. The size of the room: Consider space rating

Dehumidifiers have a space rating, which you should consider keenly when you are buying a unit. The average size of US homes is 2600 square feet.

If you intend to get a unit that can do the entire house, a whole home unit is better. It will be integrated into your HVAC system.

If you need a portable dehumidifier unit for the basement, a 70-pint Frigidaire will probably work just fine.

It is also vital not to use the unit in a space that is bigger than the manufacturer’s rating. For instance, if the space rating is 250 square feet, do not use it in a space that is 1200 square feet.

It will run all day, and it will not lower the humidity to your expectations.

Another important thing to know is that in a larger room, the dehumidifier will collect more water in a day than it would in a smaller room.

The bigger the room, the more water it will collect. Also, the more often you have to empty it unless you can connect it to a drainpipe.

3. The running time

If you run a dehumidifier for 5 hours only in a day, it will collect a smaller amount of water than when you run it for 12 hours.

It can be tricky to know how long you should run a dehumidifier or a humidifier. Should you leave it on when you are going to work in the morning?

If you leave your unit running for the whole night, it will dehumidify the air up to the set relative humidity level. It will then switch off automatically if it has a humidistat.

The running time is determined by the performance of the dehumidifier. Some units can remove up to 40 pints of water from your indoor air in 12 hours.

However, a larger dehumidifier can remove a similar amount of water in less than half that time.

Don’t do all that math regarding numbers, liters, and pints. Just use your discretion to set the timer, or just buy a unit with auto-on and off functions.

How Much Moisture Should A Dehumidifier Collect In A Day: FAQ

When people buy a dehumidifier for the first time, they are often confused about using it through the night. They also don’t know how it works or how much water it can remove.

This section on frequently asked questions sheds more light:

How much water does a dehumidifier produce?

This depends on the humidity and temperature, and size of the room, among other things. If the humidity is high, up to 90 percent, a dehumidifier can remove up to 60 pints of water a day.

Big-capacity dehumidifiers will remove more water, and vice versa. You can use the dehumidifier water to water your plants.

Will a dehumidifier always collect water?

A dehumidifier will remove water from the indoor space as long as the humidity is higher than what you have set.

It will also remove water in summer when the relative humidity is always higher. Once the humidity is restored to the set range, the unit stops removing moisture.

How fast does a dehumidifier work

This depends on the size of the dehumidifier. For instance, a big, high-capacity dehumidifier can remove 40 pints of water from the air in 5 hours or even less.

A smaller capacity one can remove the same amount of water in 12 hours or longer.

Why is my dehumidifier running but not collecting water?

This can happen for several reasons, as follows:

How much water should a dehumidifier collect in a day from a bedroom?

If the bedroom is large and the humidity is high, the dehumidifier can even collect 16 pints of water. It can also collect more in a day.

You would have to keep the door and window locked. That way, the humid air from other rooms and from outside does not come in.

Why is my dehumidifier still collecting moisture?

Until the dehumidifier lowers the humidity level to the set level, it will continue collecting water. If you have set the humidity level you want to attain on the unit, don’t worry if it keeps collecting water.

It will stop automatically. If it runs ceaselessly, the dehumidifier could be faulty.

Do you add water to the dehumidifier?

Dehumidifiers do not require you to add water because they remove water from the air. If you need to increase the humidity level, you should use a humidifier such as a Pure Enrichment humidifier.

How many gallons of moisture does a dehumidifier collect?

A 70-pint Frigidaire dehumidifier can collect up to 4 gallons of water per day. It depends on the capacity of the dehumidifier, the size of the room, and the humidity level.

How much water should a dehumidifier collect in a day in the UK?

Most places in the UK have high humidity, requiring the use of a dehumidifier in most homes. Most units can remove 4 liters a day, but high-capacity portable units can remove up to 25 liters in a day.

As an island archipelago, the UK is more humid than most places in Europe. London and Bournemouth have highs of 92% and lows of 70%.

How often do you have to empty a 70 pint dehumidifier?

If you are dehumidifying a large room with humidity levels higher than 90%, you might have to empty a 70-pint unit once in 36 hours.

With a lower-capacity dehumidifier (less than 70 pints), you might have to empty it, even for up to 3 hours a day.

Will a dehumidifier dry a wet floor?

Yes it can because it will make the air drier and then the wet floor evaporates faster. You can also use your unit to dry laundry.

When drying the floor, run the fan together with the dehumidifying unit to do a faster job.

Final thoughts

We could go on and on about how much water a dehumidifier can pull from the air in your home.

For an average home in the USA, Australia, Canada, or the UK, choose a unit that can pull between 8 and 55 pints of water a day.

Also, to reduce electricity consumption, choose a unit with an Energy Star rating. That way, you can run it for as long as necessary.

Don’t buy a small humidifier if you get really damp summers. A 50 to 70-pint one would be good for your home.

Also, get one with extras, such as accessories to attach a drainpipe so that you don’t have to empty it all the time.
