Dehumidifier FAQs
How does a dehumidifier work?
Dehumidifiers work by removing any excess water from the air and lowering humidity levels, which can get rid of damp, mould, pollutants and allergens. The moisture pulled from the air gets collected into a drip tray, and dry air is pushed back into the room.
Do dehumidifiers use a lot of electricity?
Exactly how much electricity a dehumidifier will use will depend on the model but, generally speaking, they’re energy-efficient appliances that use very little electricity, particularly when compared with some other home appliances.
Does a dehumidifier cool a room?
While dehumidifiers won’t bring the temperature of the room down like an air conditioning unit would, and it won’t cool you down in the same way a fan would, with the movement of air, it can make you feel a little bit cooler. Humid environments have the effect of making a room feel warmer while you’re in it, so, when a dehumidifier is working, extracting moisture from the air, it can make the room feel a little bit cooler.
Does a dehumidifier help with mould?
Dehumidifiers can help to prevent mould because they work by getting rid of the moisture in the air that could otherwise cause it. However, it’s worth noting a dehumidifier won’t be a silver bullet for a pre-existing mould problem. It can’t get rid of mould or its cause, whether that be too much condensation, a leak, or some other issue, but it’s a good tool to have in your armoury to keep mould at bay.
How to use a dehumidifier
First and foremost, your dehumidifier should be the right size. The tank capacity should match up to the space you’re using it in, and the scale of the damp you’re dealing with. Then, if the model allows, set your chosen humidity target – when it comes to inside the home, it’s generally recommended humidity levels be no higher than 60 per cent. To get the most out of the session, it’s a good idea to keep windows closed, as this prevents any extra moisture from getting into the space.
What causes high humidity? And should it concern me?
High humidity often occurs when there’s excess moisture and condensation, which can be caused by various factors, such as drying your clothes on radiators, as well as leaks and poor ventilation. This warm, damp environment makes an ideal breeding ground for mould and bacteria.
If left untreated, this can lead to unpleasant odours, damaged furniture, mould spots, wood rot, and even structural damage – not to mention the negative impact it can have on your health, with high humidity levels making conditions such as asthma and allergies worse.
What are the different types of dehumidifiers?
There are two main types of dehumidifiers: refrigerant and desiccant. Refrigerant models remove moisture from the air by cooling and condensing it and depositing excess water into a tank. While desiccant dehumidifiers remove excess water vapour from the air by absorbing it into chemicals, such as silica gel.
How much does a dehumidifier cost to run?
Dehumidifiers are a cost-effective and straightforward way of making your home feel drier and more comfortable. Depending on the size and energy efficiency of the model, they don’t cost much to run, even if you have them on for an extended period of time. They can also offer an eco-friendly alternative to a tumble drier, as they help dry your laundry faster by sucking the water out of your wet clothes, without releasing the moisture back into the room.
What size dehumidifier do I need?
The size of the dehumidifier you need depends on the area you’ll be putting it into. You can judge this by square metres, with most dehumidifiers sold alongside a specification of the size of the room they are most suited to. As a general rule, a compact dehumidifier will suit a small space, while a larger area requires a more generously sized dehumidifier with a big enough tank to efficiently extract sufficient moisture.
Do dehumidifiers dry clothes?
Dehumidifiers draw excess moisture out of the air so they can help dry clothes and are cheaper to run than a tumble dryer. If you’re specifically shopping for a dehumidifier with this purpose in mind, it’s worth buying one with a dedicated laundry mode setting. Couple it with a heated clothes airer, and you’ll be well on your way to drying clothes faster.
