If you have a small room or cupboard that accumulates moisture or damp, sticking a Unibond Aero 360 Moisture Absorber in there will make a big difference. If you want something cheap and simple to reduce humidity then you've come to the right place.

While cheaper moisture absorbers are available, they involve a lot of single use plastic, and the Unibond Aero 360 offers a much more eco-friendly alternative. Simply drain the liquid regularly, replace the refill every three months and it will happily sit there sucking up a surprising amount of moisture from the air in your home.

Granted, it isn’t as effective as a dehumidifier as there's no motor sucking moisture into the device, but if you're not sure if you need to splash out on the full whammy, this damp trap is a good place to start.

How does the Unibond Aero 360 Compact Moisture Absorber work?

The Unibond 360 doesn’t rely on electricity, just activated crystals which attract moisture, so it’s completely silent and will have no effect on your energy bills - double win.

I moved into a new house and the living room had a decidedly damp corner. A dehumidifier is great for clearing steam from a bathroom or kitchen, and for drying laundry, but I was facing an air quality issue that needed something I could leave to work long-term to improve matters.

The most cost effective thing to try first was a damp trap rather than a dehumidifier and I chose the Unibond one because it was the least wasteful option as you can replace the part that soaks up the damp air rather than chucking the whole thing out.

How easy is the Unibond Aero 360 Compact Moisture Absorber to set up?

The device was really easy to set up and it’s also easy to empty and refill - you just pop the back open to put a new block in and there's an outlet for the liquid on the side so you can just pour it into the toilet or sink.

What’s the Unibond Aero 360 Compact Moisture Absorber like to use day-to-day?

It’s effective at reducing the humid feeling in a small room and I notice it does collect a lot of liquid so it must be doing something! I chose the unscented refill but I still think it took a bit of the musty smell out of the room.

The downsides are that it's not the best looking thing to have on my windowsill. The refill block is also half bright blue, so any liquid and residue has the potential to stain furniture and carpets. This means we have to keep it somewhere it’ll definitely not get knocked over and be super careful when emptying it. Another downside is that the device is quite big, but I would say it’s the most effective damp trap I’ve used and it’s better for the environment to have refills.

How effective is the Unibond Aero 360 Compact Moisture Absorber?

I’ve used the Unibond Aero 360 for a couple of years now and it's definitely helped get the damp corner under control. Along with keeping the area ventilated and adding a Vitesy Natede air purifier to the room, the wall is not much less damp and the mould has disappeared - result!

Does the Unibond Aero 360 Compact Moisture Absorber offer value for money?

If you’re just looking to reduce damp in the long term in a small space, the Unibond Aero 360 is a budget option that, at under £12, costs a fraction of even the cheapest dehumidifiers. It's worth noting that refills are roughly £13 for 4 at the time of writing, and you'll need one of these every 3 months.

However, if steam and drying laundry indoors is causing damp and excess moisture in your home, a dehumidifier is probably a better bet as the Unibond Aero 360 has limited effect in larger spaces. After some trial and error, I found a good balance by having one of these moisture traps in the dampest corners of the house and a dehumidifier upstairs to deal with laundry and steam from the bathroom.

How we tested

Mumsnet editor Poppy tested the Unibond Aero 360 over the course of 2 years in the secondary-glazed living room of her 3-bedroom 1920s house. She kept a close eye on how much moisture the device was collecting, as well as its effect on the damp area she placed it in.

Poppy also took note of how straightforward the moisture absorber was to set up, refill and use day to day.
