A new dawn for dehumidifiers

The new Arete® range of dehumidifiers is the result of five years of development by our British design team, using feedback from more than 2000 customers who contributed to the design process.

Arete is the Greek Goddess of Excellence in all things and, with this range of dehumidifiers, this is exactly what we have achieved. The attention to detail has been exhaustive as we perfected every interaction between the user and the dehumidifier.

The end result is our quietest, most energy efficient dehumidifier range yet, with a host of special features to make living with Arete a pleasure.

Rated a Which? Best Buy, Arete is the perfect solution to dealing with condensation, mould and damp problems either in the home, in a garage, in an unheated basement, on a boat or in a caravan.

An appliance or part of your home?

Customers tell us that they never put their dehumidifiers away. In fact, they stay in the same area of the home all the time. So we have designed Arete to be stylish so that it looks great wherever you put it. It sits flush to the wall, has hidden castors and an air purification mode means you can use it all year round too.

Dehumidifiers should be seen and not heard

We discovered that lots of people site their dehumidifier close to the bedroom. So it became obvious that noise is a very important factor. The huge success of the Meaco ABC range of very quiet dehumidifiers proved how important it is to you that your unit is quiet. Could we make Arete any quieter without compromising some other important design ideals? It took 18 months of testing to produce the quietest large dehumidifiers we have ever made. At 40dB this dehumidifier is twice as quiet as the industry standard.

Removing clutter and confusion

The control panel on Arete One has simple and clearly laid out controls. The buttons that you use most often are larger; the buttons that you hardly ever use are small. Large buttons include controls for Smart Humidity Control and Smart Laundry either of which can be set by pressing just one button.

A Night Mode that really lets you sleep

On many devices when you select a night mode or a sleep mode they leave a light on to indicate that it is in the mode or they forget to turn off the bleeps so a press of a button is accompanied by an annoying noise. 

Not on Arete. select Night Mode and every light is turned off; the fan speed drops to the quiet low mode and there will be no bleeps. You can check the humidity levels in Night Mode quickly and quietly. And even better, little-ones’ fingers won’t accidentally take you out of this quiet mode because it takes two confirming touches to change the machine back to normal.

We feel that the Night Mode is not just for night time but anytime when you want the dehumidifier to be as quiet as possible.

It is all in the flow

Emptying the water tank is the most common action that dehumidifier owners need to do. So it was important to make sure that Arete’s large 4.8 litre tank was easy to access and empty.

We looked at how customers removed tanks, where they put their fingers and how they balanced the tank. That heavily influenced Arete’s design, which has two very large slots left and right of the machine that your fingers naturally drop into. This allows perfect purchase on the tank so you can pull it out smoothly, and place it on the floor so you can lift it by the integrated handle.

And there’s a simple but clever solution for pouring out the water. With Arete there are two spouts: one to the left and one to the right. So you can pour the water away without having to juggle or twist the tank. 

And continuous drainage...

We have not included a free hose in our dehumidifiers for a few years now because more than 90% of users told us that they do not use them, so they just end up in landfill.  Our aim is to reduce plastic waste, so we changed the way we do things.  

To make things easier, Arete comes with a hose adapter to allow you to use a standard garden hose for continuous drainage if you need it.  

This reduces plastic waste and gives you the flexibility to use the unit in the best way for you.

Clean, clean air

All Arete One dehumidifiers come with a medical grade H13 HEPA filter which is 75% larger than the filter on our popular Low Energy models. It can be used to clean the air during dehumidification and as a stand-alone air purifier throughout the spring and summer months.

Our best dehumidifier ever by far

For us, the most important thing about Arete is that is has been designed by collaboration with our customers. We have listened and learned, and all of that new knowledge is in the details that make Arete so special. Optimised for your life and the British weather. 

We think Arete is the best dehumidifier range we have ever produced. We’re looking forward to hearing what you think!

The choice is up to you!

Every Arete® dehumidifier comes with a free H13 HEPA filter so you can see first hand just how good it is. If you want to always have cleaner, fresher air in your home this filter will have to be replaced roughly every 3 months. This filter can be replaced with either another H13 HEPA filter or an active charcoal filter, the choice is up to you! Both filters do different jobs so click on the products linked above and see which type of filter suits your needs better. If you can't make your mind up, you can use both types of filters and swap them around whenever you want to.

What do reviewers think?

' It's very effective at removing moisture from larger spaces and the low noise level of the fan, at least on its slower speed, is a major bonus.' - T3 Platinum Award 2021

"If you are looking for a dehumidifier that'll do the hard work for you, the Arete One would be an excellent choice. You don't need to learn about extraction rates or figure out a complicated control panel. You literally just press a button and leave it to work." Tech Advisor Tried and Tested


It's the only Meaco range to come with a free 5 year warranty.
