Product Testing & Comparison

Our reviewer followed a specific set of guidelines to determine the best of the best:

  1. Ease of use
  2. Durability/longevity
  3. Special features

Primarily, our reviewer focused on ease of use. These dehumidifiers should be simple to set up and use, and require very little brain capacity to get going. Next up is durability and longevity, so things like sturdy design, washable filters, and energy-efficiency are all quite important to each device’s ranking.

Finally, we looked at special features such as a child lock, timer, or auto-off. Each device on this list has at least one of the above features, and several have most or all of them (#10). Now – let’s see what’s best for you, shall we?

These Are The Best Small Dehumidifiers Of 2022

1. The Best Portable Dehumidifier By PureMate (Product #PM468)

Portable Small Dehumidifier By PureMate


  • Dimensions: 15 x 13 x 22 cm
  • Capacity: 500 mL
  • Operation Mode: Continuous

It might look like an egg, but this is our top pick of the day. You can look forward to plenty of perks and features to purify the air in your home. Let’s look at what this small dehumidifier can do for you.

The unit doesn’t consume much energy and yet, it has a powerful extraction rate of up to 250ml of water per day. Since the tank is big also, you only need to empty it every other day if the dehumidifier extracts at its daily full capacity. You can also easily pick up this lightweight appliance thanks to its portable weight and design.

Its thermoelectric cooling technology is suitable for small areas in your house like the kitchen, wardrobe, caravan, and garage. Basically, any area that is exposed to damp air so that you can effectively banish humidity, mould, bacteria and dampness.

Our reviewer loved this thing. It’s incredibly energy-efficient, easy to use, and generally high-quality. While it does make noise, it’s no more than any other on this list, so it’s earned the top spot on our list.


  • Can remove up to 250ml of moisture from the air daily.
  • Lightweight design helps with portability.
  • Energy-saving.
  • 500ml tank.
  • Automatically switches off when the container is full.

2. The Best Quiet Dehumidifier By Omasi (Product #B08XXJX7S9)

best quiet mini dehumidifier


  • Dimensions: ‎28.3 x 16.1 x 13.3 cm
  • Capacity: 600 mL
  • Operation Mode: Automatic

If you hate noisy appliances, then this is the best small dehumidifier. Not only does it run ultra-quiet but you also get plenty of other perks. Let’s start with its great extraction rate – a whopping daily volume of 300 ml.

The tank can hold 600 ml so on milder days, you only have to empty the container about twice a week. The unit also automatically switches off when the tank is full so you don’t have to worry about spills. The dehumidifier is also portable and designed to save energy.

This is a particularly good dehumidifier if you want to tackle humidity in your home as soon as possible. It works very fast to extract the moisture in any area of your home that struggles with dampness and mould.

Our reviewer was a huge fan of this. It’s extremely light on energy draw, supremely quiet, and boasts a relatively large capacity. The added benefit of automatic operation ensures it’ll keep your home free of moisture for as long as you maintain its water levels – just don’t try to use it in really large rooms.


  • Ultra quiet.
  • 600 ml tank.
  • Works quickly.
  • Lightweight.
  • Light on electricity.


  • Cannot cover areas larger than 15 sq m.

3. The Best Plug And Play Dehumidifier By Pro Breeze (Product #‎PB-02)

Compact Portable Mini Air Dehumidifier By Pro Breeze


  • Dimensions: 18 x 28 x 16 cm
  • Capacity: 500 mL
  • Operation Mode: Standard

Dehumidifiers should make your life easier. That is why we picked this stylish unit as the top plug and play choice. You simply take it out of the box, plug it in and let it work. It can collect 0.25 litres of humidity per day and features an easy-to-dispense container with a tank capacity of 500ml.

It´s super easy to use and simple to control. This compact model extracts humidity from any room in your house or office and can even assist in drying laundry indoors. As a bonus, the unit also works quietly.

This is another fantastic little dehumidifier. It takes up very little room, and is extremely energy-efficient. While it can’t operate in larger rooms, it’s great for smaller ones like the bathroom or bedroom – especially if you want to dry out your towels or clothes a bit more easily. Overall, our reviewer highly recommends this little bad boy.

4. The Ultra Quiet & Efficient Dehumidifier By Pro Breeze (Product #‎PB-03-UK)

Ultra Quiet & Efficient Dehumidifier By Pro Breeze


  • Dimensions: 22 x 16 x 30 cm
  • Capacity: 1500 mL
  • Operation Mode: Automatic

Here’s another great choice if you’re searching for a dehumidifier that whispers rather than rattles. While this unit is larger than most small dehumidifiers (2 kg), you can still move it to a new location without too much trouble. The larger size is also better if you want a bigger water tray (1500 ml).

The unit can remove up to 500 ml a day, making it perfect for a home or area with particularly bad humidity or dampness. You can also look forward to an auto shut-off when the water tray is full, an energy-efficient design, and great results in medium-sized areas like bedrooms, garages and caravans.

Our reviewer liked this for its combination of relatively small size with a surprisingly large capacity. It’s lightweight and compact enough to fit into smaller spaces, while having a large enough tank that it can run for quite a long time. Its one downside is that the water tank is a bit difficult to drain.

5. The Top Cordless Portable Dehumidifier By Pro Breeze (Product #‎PB-04)

best portable cordless dehumidifier


  • Dimensions: 16.5 x 3.5 x 10.2 cm
  • Capacity: 150 mL
  • Operation Mode: Automatic

This tiny dehumidifier is a lifesaver when you need to control the air quality and you don’t have an extra plug available or you want to move it often between rooms. Since it is cordless, you can effortlessly use it anywhere you like. But let’s look at what else you can expect from this stylish appliance.

This unit is perfect for small spaces like a closet or kitchen cabinet. It’s also very effective to use if you’re on the go. For example, put it inside your gym bag or boat to keep things dry. It’s also completely safe to use around kids and pets.

Our reviewer loved this, but not for an entire room. Its wildly small size makes it great for closets and such, but it can only hold 150 mL, meaning you’ll be emptying it constantly in anything larger than a closet. On the plus side, though, it’s made and operated through renewable, environmentally friendly means, so that’s nice!


  • Small and portable.
  • Stylish.
  • Safe to use.
  • Cordless.


  • It’s incredibly small
  • Low capacity

6. The Best Portable Economical Mini Dehumidifier By Hysure (Product #T8-UK)

  • Dimensions: 16.3 x 10.7 x 26.7 cm
  • Capacity: 700 mL
  • Operation Mode: Automatic

This dehumidifier is the whole package. It looks great, no matter where you put it. The unit is simple to operate and it extracts enough moisture to remove bad odours, damp and mould.

This energy-efficient dehumidifier can extract 300 ml per day. Using it is as simple as activating its one-touch control and removing the 0.7-litre tank when full.

Other features include a light that indicates either standby or dehumidifying, area coverage up to 15 square metres, a low noise level of 35dB and a portable weight of around 1kg.

Our reviewer found that this was a great dehumidifier for extremely hot and humid environments. While it struggles to drain moisture (and gather it) in cold temperatures, it’s fantastic for hot, humid areas. Keep this one in mind for the bathroom, too – it’ll help dry out towels and keep the bathroom from building moisture after a shower.


  • Chemical free, creating a safe indoor environment.
  • Easy to use and simple to control.
  • Ideal for small spaces including closets, bathroom, etc.
  • Suitable for drying laundry indoors.

Our review found that this was a compact, lightweight, and quite a slick-looking dehumidifier. Its filter is washable, which is a nice little bonus, as is its incredibly quiet operation. While it lacks a car adaptor and struggles with very large rooms, it’s still great for smaller areas.

Our reviewer loved the reusability of this dehumidifier. The washable filter drastically improves both its longevity and quality of function. Add in the large tank capacity, auto-off, and good looks, and this is a pretty good choice. While it lacks a timer, it’s still quite a solid product.

Your Buying Guide To Dehumidifiers

The right portable dehumidifier can improve your health and prevent moisture damage from causing expensive repairs. Our guide includes all the essential advice you need to find the perfect mini dehumidifier for your home, caravan or office!

What To Consider Buying A Mini Dehumidifier


Make sure that the size and weight is portable and does not take up too much space. This is important if you need to place it on your office desk or in a caravan where space already comes at a premium.

Daily moisture removal rate

Another thing to take into consideration is removal rate. The better economical dehumidifiers will usually remove between 200ml and 500ml of water from the air every 24 hours. The amount of moisture removed will however, depend on relative humidity and prevailing temperatures.

Noise output

Small dehumidifiers are usually well designed for homes and rooms such as the bathroom, bedroom or even office as well. Our advice – you’ll want a unit with quiet operation.

Power consumption

Small dehumidifiers usually operate on a 12 or 9 volt power source. This however isn’t really important. The rating you should really be looking at is the wattage rating. A higher wattage rating means you’ll end up paying higher electricity bills.


Q. How do small dehumidifiers work?

A. Small dehumidifier machines work by pulling air through a special filter and cooled coils. Water condenses on the coils and then drips into a tank.

Q. Where is the best place to put a dehumidifier in a room?

A. The best position to put a dehumidifier in a room is the centre or some distance (preferably 6-12 inches) away from back walls and furniture. This will let the dehumidifier get good airflow around it.

Q. Should I put a dehumidifier in my crawl space?

A. You should put a dehumidifier in your crawl space to protect your home from moisture-induced wood rot and to ensure a comfortable living space for your family.

Q. How do I know if I need a dehumidifier?

A. You know you need a dehumidifier if:

  1. Moist stains are found on walls or ceiling
  2. Condensation covers your windows
  3. Mould is visible
  4. There are musty odours.

Q. Is a dehumidifier good to dry clothes?

A. A dehumidifier is good for drying clothes because it draws wetness from clothes and can help them dry quicker.

Q. Will a dehumidifier in the basement help the whole house?

A. A dehumidifier in the basement will help the whole house because the humidity is mostly transferred from your basement’s walls and ceiling.
