A dehumidifier removes moisture from the air by drawing the air in, collecting the condensation in a pan, then expelling moisture-free air. People usually feel comfortable if the relative humidity falls between a range of 20 to 60 per cent.
Using a dehumidifier in conjunction with an air conditioner can keep your house cooler by reducing the humidity inside the home.
Keeping your home at a humidity level of about 50 per cent or lower will prevent mould from forming in wet areas like bathrooms and basements.
People who are allergic to things like dust mites find that their allergies act up less if they run a dehumidifier.
SierraClubGreenhome.com notes that drying out the air can help you better recover from respiratory ailments like pneumonia and improve breathing conditions for people with asthma.
Dehumidifiers are built to be portable, so you can easily move them from one room to another if you need to dry a different area of the house.
