Feeling comfortable and healthy in your home is incredibly important, and a dehumidifier can be a great way to improve your air quality and solve a whole host of breathing issues.
If your house has high humidity levels, this can be a perfect breeding ground for mould and dust mites, which can contribute to an increased risk of asthma or eczema. Too much humidity can also cause damp, mould and mildew, which can damage your home, and can lead to rooms smelling unpleasant or feeling stuffy.
What do dehumidifiers do?
Dehumidifiers work by removing moisture from the air and collecting it in a water tank. Depending on the machine, they can also collect dust and dirt in their filters. Depending on your dehumidifier, you can either then empty the water tank, or connect a hose for continuous drainage.
Removing the moisture and dust from the air makes the environment less appealing to dust mites and other unwanted pests in the home.
What are the benefits of a dehumidifier?
Using a dehumidifier isn’t just useful for preventing allergies: it can also help your laundry to dry faster, and to help your home heat up faster. They’re also inexpensive to run, making them a wallet-friendly addition to your home.
So which dehumidifier should you go for? First, take into account the size of your home and the rooms you’ll be looking to dehumidify.
If you’re on a budget and looking to remove the moisture out of a small room such as a home office or utility room, you can buy one on the smaller and cheaper end of the scale, while if you’re looking for strong dehumidifying power throughout your home and have the space for a heavy duty machine, you’ll want to invest a bit more in your device.
