I tried the bestselling dehumidifier from Amazon – and saw bathroom black mould vanish

The frosty, chilly weather has brought back the issue of dampness and mould in my home, which could become a significant problem if not addressed promptly. Thankfully, has been a great help.

After moving from a high-rise flat to a riverside house where condensation is a major issue, I learned last winter that the windows are constantly wet on the inside; paint peeling off the wall is a particularly bad problem. While running heaters can help reduce condensation in the house, it’s not a cost-effective solution in the long run.

I’ve since purchased the to help combat the rising damp. For anyone else looking to eliminate the increasing moisture felt in many homes as temperatures drop, it’s now reduced from £249 to £189.95, reports .

costs just 7p per hour to run and can remove up to 20 litres of excess moisture from a room in 24 hours, whether it’s in a bathroom, living room, or kitchen. According to Swan, the device also “reduces mould spores and dust mites to improve air quality, ideal for those with respiratory problems and allergies.”

My main challenge is the bathroom. It lacks extraction fans and the windows are permanently sealed, so it was no surprise to find tiny mould spots on the ceiling and along the window sill. 

I set up the Swan model right next to the shower and let it run for two hours at an automatic speed to see if it could reduce any condensation on the window — the LED display showed the room’s humidity level, which was a shocking 86 percent. For optimal comfort and to maintain a safe, you should aim for humidity levels between 40 percent and 60 percent.

It’s quite astonishing, but after just 30 minutes of operation, the mist on my window was completely eliminated and the room’s humidity gauge showed a drop to 66 percent. True to its energy-saving promises, the device automatically switched off after its two-hour timer concluded.

Upon emptying the collected water, I decided on a rerun a few days later, this time extending it to three hours. By week’s end, the sinister black mould on the ceiling had vanished, as did the smattering of dark spots.

However, the dehumidifier does not operate silently; it’s quite audible, which is less than perfect. My bathroom lacks a power socket, forcing me to grapple with the slightly short cable and reach for an extension to connect it to the closest outlet.

Testing continued in my kitchen where peeling ceiling paint signaled moisture troubles, likely from culinary activities. The dehumidifier served as a stopgap remedy, holding off the deterioration, but a sturdier solution seems necessary to combat cooking-related condensation.

The four-litre tank can fill up rather quickly if left running for a day, but when compared to other dehumidifiers, it’s quite a generous size. The originally priced at £249, is now available for £189.95 on Amazon, offering customers a £60 saving. 

For those looking for a non-electrical dehumidifier, the has been a hit, especially for use in wardrobes and guest toilets.
