I noticed that ASDA (UK Walmart) was pushing these Unibond "moisture absorbers". The packaging is very misleading and tries to present these units as room dehumidifiers, giving condensation, mold and peeling wallpaper as examples of what they can "prevent". In reality they wont, because whereas a real dehumidifier will pull many litres of water out of the air in a damp room every day, this unit will only draw out about 700ml at best in a month or longer.
These units use cylinders of compressed hygroscopic chemical, (probably calcium chloride) to absorb moisture slowly, dissolving into liquid as they do so. You end up with the collection tray full of a saturated chemical solution which is not only quite corrosive to many metals, but will cause permanent damp stains if it gets spilled.
These things might be OK for keeping the humidity down in a cupboard with low air flow, but for room use they are nothing more than a placebo, and useless as an actual dehumidifier.
When the chemical block has fully dissolved in these units you have to pour the concentrated chemical solution down your drain and buy a new block. Compared to a real dehumidifier these units cost over ten times as much to extract a given quantity of water and do so very slowly.
In short, if you have a humidity issue then don't waste your money on this gimmick. Buy a proper compressor or desiccant-drum based dehumidifier that will actually do the job.

Works good and I like I can use an app to change settings
I have one of these in my work van and it keeps the van nice and dry. 👌
I did order a different one just now after watching your video 😊
I live in a student house with improper air movement, neither bathroom has a fan, only one has a window. I use Calcium Chloride Ice melter to keep the humidity down around the bathrooms, to keep the mold away. It's not a substitute for a dehumidifier but it does enough for the price. I'd avoid buying any of the "DampDry" or similar products, theyre WAY over price.
It seems to me that a small desk fan would make it work a lot better
Big Clive got them all! I really suggest taking a look into this channel for basic repairs and learning.
Humidity theatre.
I have one it works and lasts 3 months
I live on a boat and the Aero 360 keeps my entire boat condensation free. I have a hygrometer and it reads air moisture as 48% with the Aero in the boat. I took it out for 1 day in the spring and the moisture reading went up to 68% so scientifically it definitely works.
I got mine just to keep moisture levels down, it’s got about 1 1/2 – 2 ml of water in after after 3hrs 😬
One of those spilled out behind the seat of my car.
Drying the carpet was supremely annoying, don't want to know how it looks under there.
