Our verdict

In recent years, adding a dehumidifier to the family home has become a bit like the air fryer craze. Now lots of homes have them, but which is the best one and how well will it suit your family’s needs?

Dehumidifiers can be used to tackle a number of things, from keeping mould at bay to drying washing. Sometimes, a gadget comes along that ticks all the boxes.

Our tester Christine used her Pro Breeze 20L OmniDry Smart Dehumidifier for a month in her home and found that it revolutionised the way she dried her washing. 

“Compared with other dehumidifiers I have used, the OmniDry 20L feels more modern and user-friendly thanks to the app control, clear humidity monitoring and dedicated laundry mode,” she said. 

“It was also quieter and more effective at controlling moisture in my kitchen, particularly when drying washing indoors.”

One of the big advantages to this dehumidifier is its sizeable tank. With a 4L capacity, the brand says: ‘less emptying, more relaxing: The 4L water tank ensures less frequent emptying than other brands with an additional hose included.’

Christine found this to be true, discovering that the tank needed emptying infrequently, despite the dehumidifier’s daily use.

With Quiet Mark certification, the Pro Breeze 20L OmniDry Smart Dehumidifier is billed by the brand as a ‘market leader in low noise’.

Christine found that it was very quiet, although when using it in laundry mode it did emit more noise than when in other modes.

“The only minor downside was that laundry mode is slightly noisier than standard operation due to the higher fan speed, although it was still perfectly acceptable for everyday use,” she said.

Overall, though, Christine thinks this dehumidifier deserves its Which? Best Buy accolade, telling us:

“The biggest strengths were its effective moisture removal, useful laundry mode, quiet operation and ease of use. The smart app was simple to set up and made it easy to check and adjust settings remotely. I also liked the clear display, large water tank and the fact that it noticeably reduced condensation in my kitchen while helping laundry dry more quickly.”

How we’ve tested

Our tester Christine lives in a three-bedroom semi-detached house and wanted to tackle excess moisture and condensation in her home. She tested the Pro Breeze 20L OmniDry dehumidifier, using it to see how well it managed everyday moisture levels, reduced condensation on windows and helped keep the room feeling fresher and drier after cooking and laundry.

“I wanted to tackle excess moisture and condensation, particularly in the kitchen where cooking often creates steam and humidity,” she told us. “I also do my washing in the kitchen, which can add extra moisture to the air, especially when drying clothes indoors.”

Christine tested the dehumidifier for four weeks and said:

“This gave me a good opportunity to see how well it managed everyday moisture levels, reduced condensation on windows and helped keep the room feeling fresher and drier after cooking and laundry.”

What’s in the box? 

Inside the box, you’ll find the Pro Breeze 20L OmniDry Smart Dehumidifier, the instruction manual and the water outlet pipe for optional drainage use.

How easy is it to set up and use?

Christine found it easy to get her Pro Breeze dehumidifier working, thanks to the clear instructions.

“Unpacking and setup were very straightforward. The unit was well packaged, and the instructions were clear and easy to follow,” she said.

Christine mostly used the dehumidifier in her kitchen, but also found it easy to move around and use in different rooms when needed.

“Finding a suitable position in my kitchen was simple, as it fitted neatly on the floor without getting in the way,” she shared.

“Despite mainly using it in the kitchen, I found it lightweight and manageable enough to move between rooms when needed. Overall, the whole process from unboxing to getting it up and running took only a few minutes and required very little effort.”

As for how well it performed when in use, Christine was impressed with how effective it was at reducing humidity.

“The dehumidifier noticeably reduced humidity levels in my kitchen, particularly after cooking and when doing laundry. The room felt fresher and drier, and I noticed less condensation forming on the windows,” she explained.

Christine mainly used the dehumidifier in her kitchen. She noticed more moisture when cooking and drying laundry at the same time, but found that the dehumidifier coped well.

“I typically used the unit in its standard operating and laundry mode for several hours each day, often after cooking or washing clothes,” she told us.

“The display showed a steady reduction in humidity over time, and the improvement in the room's overall comfort and moisture levels was easy to notice. The machine coped well with the additional moisture generated from cooking and indoor laundry, helping to maintain a more comfortable environment.”

How much water does the Pro Breeze 20L OmniDry Smart Dehumidifier collect?

Although this dehumidifier can extract up to 20 litres of moisture a day, its tank holds four litres. At maximum extraction, you’d need to empty it several times a day unless you used continuous drainage.

Christine found that despite using the dehumidifier for several hours at a time, she didn’t need to empty it often, telling us:

“During the testing period, I typically emptied the water tank every few days, although this varied depending on how much cooking and laundry had been done. When using laundry mode, the tank filled more quickly due to the extra moisture being removed from the air.”

As for emptying the full tank, Christine found it straightforward with no spillages.

“The tank was easy to remove, carry and refit, with a comfortable handle and a design that minimised the risk of spills,” she said.

“I was able to empty it at the sink without any difficulty, and it slid smoothly back into place afterwards. I didn’t use the continuous drainage option during testing, as the tank capacity was sufficient for my needs, but it is a useful feature for anyone wanting to run the dehumidifier for extended periods without needing to empty the tank manually.”

The Pro Breeze has a dedicated 'laundry mode' setting.

Does Pro Breeze 20L OmniDry Smart Dehumidifier get your laundry dry?

This dehumidifier has a dedicated ‘laundry mode’, and during the month that she tested it, this was the setting Christine found herself using the most.

“I used it while drying a typical washing load consisting of clothing, towels, bedding and household items on an indoor airer in my kitchen,” she explained.

“Normally, drying indoors can take well over a day, particularly in cooler weather, and often leaves the room feeling humid with condensation on the windows. With the OmniDry 20L running in laundry mode, clothes dried noticeably faster, and the air felt much fresher. The room remained comfortable, with far less moisture build-up than I would usually experience.”

Christine was also impressed with how evenly thicker items dried when aided by the dehumidifier.

“I also noticed that towels and thicker items dried more evenly, and there was less of that damp feeling that can linger when drying laundry indoors,” she said.

“For larger loads, I occasionally repositioned a few items on the airer to improve airflow, but this is something I would normally do anyway. I did not need to leave the dehumidifier running significantly longer than expected, and most items were dry within a shorter timeframe than usual. Thicker items felt less damp and dried more consistently, making Laundry Mode particularly useful when drying washing indoors in the kitchen.”

How noisy is the Pro Breeze 20L OmniDry Smart Dehumidifier?

The OmniDry has a rated noise level of under 36dBA and Quiet Mark certification, which should make it pretty unobtrusive.

Christine definitely found this to be the case, commenting:

“The OmniDry 20L was impressively quiet in everyday use and never felt intrusive.”

She did find that some modes were louder than others, but overall the machine remained pretty quiet.

“In standard operation, the noise was comparable to a low background fan and was easy to ignore after a short time,” she explained.

“Laundry mode was slightly more noticeable due to the higher fan speed, but it was still perfectly acceptable for daytime use. I didn’t experience any significant vibration, rattling or disturbance, and the unit remained stable on the floor throughout testing. The compressor cycling was smooth and unobtrusive, with no sudden changes in noise levels. Overall, I found it quiet enough to run for extended periods without affecting normal daily activities.”

Is the app easy to use?

The Pro Breeze 20L OmniDry Smart Dehumidifier has a smart app, which means you can control it from anywhere using your phone or home devices like Alexa and Google Home.

Christine found the app easy to use and also handy for checking in to see how her laundry was faring while it was being dried.

“Pairing the dehumidifier with the app was quick and straightforward and I’m not that technically minded but still managed to do it without calling any of my children!” she admitted.

“The instructions were easy to follow, and I had the unit connected and ready to use within a few minutes. Day-to-day control through the app was reliable and convenient, allowing me to check humidity levels, change settings, switch between modes and monitor the unit without having to be in the kitchen.”

Christine used the app most days when using her dehumidifier to check the progress of her laundry, and found it to be a useful tool rather than an unnecessary extra.

“The app added extra convenience by letting me make adjustments remotely and keep an eye on conditions in the room,” she said.

“I particularly found it useful when drying laundry, as I could monitor the dehumidifier's performance without needing to check the unit itself. Overall, the app complemented the onboard controls well and added useful functionality rather than feeling like an unnecessary extra.”

The OmniDry has a rated noise level of under 36dBA and Quiet Mark certification.

Is the Pro Breeze 20L OmniDry Smart Dehumidifier worth the money?

With an RRP of £200, this isn’t a cheap dehumidifier, but its multiple modes, large tank and Quiet Mark certification help justify the price. Christine thinks it’s worth the money.

“Based on my experience, I would consider buying it at its current price because it performed well, was easy to use and helped tackle two common household issues at once: excess humidity and indoor laundry drying,” she told us.

“I think it would particularly suit families, people who dry clothes indoors, homes affected by condensation and damp, and anyone looking for a dehumidifier that can largely be left to manage humidity levels automatically.”

Final verdict: is this the right dehumidifier for you?

Although it has a premium price tag, our tester felt this dehumidifier was worth its weight in water. It did everything it needed to do: dried washing quickly, reduced moisture in the air and had a handy app to keep tabs on how it was performing.

Christine found it easy to use, easy to clean and easy to move, and felt it was well worth its RRP.
