Gadgets for Removing & Preventing Mould
Here are some great tools and gadgets you can use to fight mould and stop it from developing in the first place.
1. UniBond Aero-360 Pure Moisture Absorber Device
The UniBond Aero-360 has a 360° air tunnel that helps collect moisture from the air, thereby preventing mould and mildew.
It collects moisture through an absorbent tab which also helps remove odours and then converts the moisture into a salty solution which you can then empty into the sink. The UniBond Aero-360 is small at just 24.2 cm high and 18.9 cm wide.
It doesn’t need to be plugged in, so it won’t increase your electricity bill, and it’s also completely silent.
However, it works more slowly than an electric dehumidifier, as it only removes moisture that passes by it naturally rather than using power to suck the moisture in.

Tips for Preventing Mould
Mould can cause many problems in our homes and can also cause a potentially serious health risk, particularly for those suffering from allergies or asthma.
Even if you don’t suffer from allergies, mould can cause irritation to your eyes, skin, throat, nose and lungs.
Mould can also seriously damage your property, resulting in expensive repairs if left untreated.
Luckily there is plenty you can do to prevent mould and to protect yourself and your home.
What Causes Mould?
There are several causes of mould in the home. Firstly, mould forming due to excess moisture can be caused by problems with the actual structure of the building, such as leaking pipes, rain leaking in through the roof or around windows (penetrating damp), or rising damp in basements.
The other main cause of mould inside our homes is condensation. When indoor air can no longer hold moisture, condensation begins to form, particularly on cold surfaces such as windowsills, mirrors and walls.
Cooking, showering, bathing and drying washing indoors are just some of the everyday activities that increase the moisture in the air causing more condensation to form.
If there is too much condensation on a surface, mould may begin to grow that looks like a small group of black dots.
Reducing moisture in your home is one of the easiest ways to prevent mould forming. It’s easy to make simple changes to do this, for example:
- Dry clothes outside whenever possible and avoid drying them on radiators if you have to dry them indoors.
- Keep the lids on pans when cooking.
- Vent your tumble dryer outside if you can.
- Open bedroom windows as much as possible, even in winter.
- If any of your household appliances have drip trays, make sure they are emptied regularly.
- Dry wet areas immediately. This applies to both small everyday spillages, and to more serious problems such as wet floors caused by a leak.
You might also want to consider purchasing a dehumidifier to reduce the level of humidity in your home, particularly if you need to dry clothes inside often or if you struggle to reduce the moisture in your home using the methods above.
Improving ventilation is another important step to help prevent mould from forming in your home.
It’s a good idea to ventilate rooms regularly and to open doors between rooms, to allow air to circulate around your home.
However, if you’re cooking, showering, bathing or doing laundry, you’ll need to close the door of the room that you’re in and open a window.
It may be worth getting an extractor fan installed in the bathroom, to run whenever you’re in the room to reduce condensation, and if possible let the fan run for 30 minutes after a bath or shower.
Identify and Repair Structural Problems
As mentioned previously, some damp and mould problems are caused by structural problems, for example, leaks in a roof, around a window or in pipes, or even rising damp. Even if repairs seem expensive initially, fixing problems sooner rather than later will prevent mould developing.
Many leaks in homes are caused by problems with faulty roof gutters, so it’s worth getting these checked regularly too.
Monitor Moisture Levels in Your Home
Moisture meters (hygrometers) can be bought easily and cheaply from hardware shops or online, and are a good way to monitor and control the moisture levels in your home and detect potential problem areas. Aim to keep humidity levels below 60% if possible.
Keep Your Home Warm
If you want to prevent mould, you need to keep your home as warm as possible, particularly in colder weather. Cold air can’t hold moisture as well as warm air, and therefore condenses on cold surfaces and mould begins to grow.
Installing loft and cavity wall insulation and draught-proofing windows and exterior doors can help keep your home warmer and means reduced energy bills too.
How to Reduce Mould in the Bathroom
Mould can be a big problem in bathrooms and other areas that have a damp atmosphere. Mould is a type of fungus that thrives in a warm environment where the relative humidity is 70% or higher.
Fertile mould produces spores that are carried around in the air and so spread further.
Mould appears as a black deposit on ceiling and walls, and not only looks unsightly and has an unpleasant smell but also causes damage to walls, floors and ceilings as well as giving rise to breathing difficulties for those who have respiratory problems. So, it’s important you prevent or eliminate it.
How to Prevent Mould
As with most things, prevention is better than cure, so trying to avoid mould occurring will always be preferable to attempting to eradicate it once you’ve got it.
Since mould thrives in damp and warm conditions, a bathroom is a perfect environment for it to flourish. Your aim, therefore, is to change these conditions and so prevent the build-up of mould.
1. Let moisture escape
The most obvious way to reduce the amount of moisture is to remove it from the bathroom. That can be done by opening a window while showering or bathing so that steam can go outside naturally.
In cold winter months, this may not be practical and the best alternative is an extractor fan that will remove the worst of the steam. An extractor fan is also essential for bathrooms that do not have windows, such as those in flats which may not have outside walls.
Run the extractor while showering or bathing and up to thirty minutes afterwards to be most effective, ensuring the bathroom door is closed to prevent the moist air circulating throughout the house.
As well as helping to reduce the level of moisture, adequate ventilation is also good for health generally.
2. Reduce condensation
Moisture in the bathroom is a bigger problem when it condenses as water on cold surfaces, which can be alleviated by keeping the room well heated.
Effective insulation will certainly help here while air conditioning will also purify the air and a good dehumidifier will remove moisture from the air, both in the bathroom and throughout the rest of the house. Aim for humidity levels of no more than 50%.
3. Remove excess moisture
Preventing a build-up of moisture is also helped by removing excess water at the outset.
Always squeegee the shower dry when you’ve finished so the excess water drains away rather than remaining on the walls. Fix any drips or leaks since they will otherwise constantly add to the room’s moisture.
Don’t leave wet sponges and cloths in the shower or bath since they will add to the level of moisture in the atmosphere.
If you can’t put them in a sealed container or cupboard, at least squeeze them out thoroughly so they’re relatively dry.
4. Keep the bathroom clean
It’s also important to keep the room as clean as possible since dust is a source of food for the mould and the mould spores travel through the air.
Dust at least weekly with a slightly damp cloth and clean all surfaces with a general-purpose cleaner, drying thoroughly to reduce moisture.
Also, wash any mats and shower curtains once a week and ensure they’re completely dry before putting them back.
Lastly, mould thrives in dark areas as well as those that are warm and damp. So where possible, make sure your bathroom is well-lit and don’t leave the blinds down throughout the day.
How to Get Rid of Mould
If despite your best efforts you still have mould in your bathroom, it’s important you get rid of it straight away before it becomes a major problem. While treating the mould:
- Wear rubber gloves and possibly protective goggles
- Ensure the room is well ventilated and, especially if you have respiratory problems, wear a dust mask
- Never try to scrape off the mould because this will release spores that you are likely to breathe in.
Treatment generally involves a few simple steps:
- Wash down affected areas with a mixture of one part bleach to four parts water. You may first want to test on a small area since bleach can damage some paint. Alternatively, use other products such as specialist mould remover sprays or anti-bacterial sprays, although the latter is likely to be less effective.
- Remove any affected sealant and apply fresh in its place.
- Ensure all areas are clean and dry.
- Repaint the walls and ceilings with a barrier solution to prevent further penetration.
- Once dried, apply a paint topcoat. You can add fungicide to the emulsion to prevent a reoccurrence of the mould.
If the mould covers large areas, has penetrated into the walls and ceilings or you are unable to eradicate it, you must seek professional help. Failure to do so can result in further damage to your property and increased danger to your health.
Even when the problem seems to have been cleared, that’s not the end of the matter. You’ll still need to concentrate on keeping the bathroom clean, warm, well-ventilated and free of excess moisture. If you don’t, the problem will recur time and time again, so be on your guard.
As with everything, prevention is better than cure. Make sure your bathroom has good ventilation and isn’t too cold, and use an anti-mould paint on the walls and ceiling if possible.
You can also measure the humidity levels in your bathroom using a hygrometer to check that your efforts to reduce the humidity are working.
