I was talking to a friend recently and I was amazed to find out that they had a dehumidifier at home. I suddenly started worrying that maybe I needed a dehumidifier. But what is a dehumidifier and what does it do? Obviously, I needed to go and do some research to find out all about this piece of equipment.

I have never even considered buying a dehumidifier before, so I researched dehumidifiers on the internet. I found a great site at Dehumidifier Web where they explained all about dehumidifiers, how they work, and the best ones to buy.

What Is a Dehumidifier?

A dehumidifier removes water from the air, so the room is not too humid. As the excess moisture has been removed from the air, you will have less condensation and less damp on your walls so there is less chance of having mould growing. There are two types of dehumidifier. Refrigerant and desiccant.

  • Refrigerant dehumidifier.A refrigerant dehumidifier is sometimes known as a compressor. It draws in air through a filter and then cools it down. The water condenses onto the cold coils inside the compressor and then drips down into a water tank.
  • Desiccant dehumidifier.As the name suggests this uses as absorbent material to take the water from the air.This material is then heated and the moisture drips down into the water tank.A desiccant dehumidifier may use more energy than refrigerant dehumidifiers due to the amount of work it is doing.

Do I Need a Dehumidifier?

You may need a dehumidifier if you notice signs of damp.This might be things like condensation on your windows or it could be a lot more severe. Just bear in mind though that there are easier ways to treat excess moisture before investing in a dehumidifier.

  • Common sense would tell you that if you’re taking a bath or a shower, then open a window in your bathroom.This does a great job of removing much of the excess moisture that is created by the steamy environment.
  • Extractor fan.Where possible fix an extractor fan in the rooms where you have a lot of moisture for example bathrooms and utility rooms.Make sure it can cope with the size of the room.
  • Wipe walls. Wiping down the wet surfaces in your bathroom after showering or having a bath will remove a lot of the moisture from the room. Make sure thatany cracks in your walls have been sealed as well.
  • Washing clothes.To reduce the moisture in the air don’t leave your wet clothes to dry on a radiator.The best way to dry your clothes is outside on the washing line. If this is not possible then try to dry them near an open window.
  • Using your extractor fan when cooking will not only reduce the moisture from the air but should get rid of some of the smells too.
  • If you have moisture that seems to be leaking in from the outside, then check that any gutters are not clogged with leaves and debris.You may find rainwater is being directed towards the house.
  • Tumble dryer. Try and vent your tumble dryer to the outside. This will remove a lot of the moisture from your utility room or kitchen.
  • Damp proof. If you have structural rising damp, then look to have a damp proof course installed.

Benefits of a Dehumidifier

Although they may cost money to run, and there are always other ways that you can reduce damp, a dehumidifier does have other benefits besides removing the moisture from the air.

  • Common triggers for allergies including mildew, mould, and dust mites thrive in humid environments. Small rooms such as bathrooms or kitchens are prone to damp.This can trigger some allergic reactions like stuffy nose or watery eyes.Some of these allergies are said to be contributors to childhood asthma.
  • If you have damp or mildew in your house this can lead to musty smells. Dehumidifiers not only remove the moisture but also reduce the smell.
  • Having a dehumidifier means you have a less humid environment in your house. This means metal things won’t rust, foods like bread will remain fresh, and clothing will dry faster.
