Here at Olympus Tool Hire in Newton Abbot we find that our dehumidiers and heaters are one of the most popular tools to hire and buy at this time of year for our homes and businesses. This article from Which gives seven tips to get the most out of your dehumidifier:

1. Empty it regularly

Empty the collected water out of the dehumidifier after every use and before moving it to another room. This will help the unit to work more effectively for longer.

2. Think about position

Keep your dehumidifier away from walls, curtains and furniture and keep all doors and windows closed when you use it. The more centrally the unit is placed, the more moisture it should remove from the air.

3. Get the humidity right

Generally, you should aim for a relative humidity of between 30% and 50%. But be careful if you’re using your machine to protect valuable items, such as guitars or classic cars – you will need to check specific humidity levels with a specialist. Some dehumidifiers are able to work at a range of humidity settings.

4. Vacuum first

It’s a good idea to vacuum your floors before you switch on your dehumidifier, so that it doesn’t spread dust particles. This is particularly important if you already suffer from allergies. If you do have allergies, you should look out for a dehumidifier that has a dust filter. Plus you should choose a low humidity as this is better for controlling dust mites – although the lining of your throat can feel uncomfortable at lower than 30% relative humidity.

5. Be cost-effective

Dehumidifiers usually take a few hours to reduce humidity. So unless you enjoy giving money to your energy supplier, you will need to be smart about when you use one. If you’re on a tariff that offers you cheaper electricity at night, such as Economy 7, set the timer to run your dehumidifier at this time. Don’t worry if you’re not on one of these tariffs though – you can still make savings. Most of our Best Buys are more effective in warm temperatures, so run yours only when the heating is on. The humidity in a room can affect your allergies – set your dehumidifier to 30%-50%

6. Get frost control

If you’re using a dehumidifier in a cool room – for example, in a basement – check the dehumidifier has frost control. This will stop the dehumidifier freezing up if it gets too cold during use. You can check our product reviews to find out which models do – and don’t – have frost control and other features, such as inbuilt humidistats, digital displays and clothes drying functions.

7. Use at the right times

Dehumidifiers are most effective when you have excess moisture in your home. So switch yours on just after you’ve taken a shower, or if you’re drying washed clothes indoors. But dehumidifiers are no cure for a serious damp problem. Keep reading to see how to deal with larger scale damp problems.

Rising damp and penetrating damp

Although dehumidifiers are a cost-effective way to prevent damp from taking hold in your home, they can’t remove cases of serious damp. Our expert guide helps you identify the kind of damp that’s affecting your home. If you discover that you have rising damp, you should check how effective your damp-proof coursing is. Although you’ll need an expert to assist, this may not be as expensive as you think – it may just be a case of digging away any soil that is above the level of the damp-proof course. Solving penetrating damp is unlikely to be quite so easy though. You’ll need to identify where the cause of the damp is coming from and then mend it. Some of the most common causes are a dodgy roof, leaky guttering and gaps in window and door frames. Get to the heart of the problem now, before your damp problem causes even more damage – see all our advice on dealing with damp.
