Excess dampness in the air can cause issues like mold and an increase in dust mites. A good dehumidifier can reduce the amount of moisture in the air, mitigating the problem. But what's the best type to use, and how do you choose a good dehumidifier?
How To Choose a Dehumidifier
If you've noticed that your home is excessively damp and decided to buy a dehumidifier, you'll immediately discover that there are thousands of different ones on the market. Choosing the right one can be tricky, so you need to set yourself a few parameters. For example, how big is the room you want to use it in and how damp does it get? You'll need one with a large capacity if you're using it in a large, well-used kitchen. Your local climate is important too; you'll need a model with a much larger capacity if you live near the swamps of Florida than if you're located in the dry conditions of New Mexico.
The Three Types of Dehumidifiers
There are three main types of dehumidifiers. The first of these is the refrigerant dehumidifier. This works in a similar way to your refrigerator, drawing moist air through a fan and condensing water onto a plate. These are great at normal room temperatures and really damp conditions but can form ice in colder climates, reducing their effectiveness. Next is the desiccant type. This contains a granular material that absorbs moisture as it rotates on a wheel and is useful in cooler locations, such as your garage or basement. Unfortunately, these are power-hungry. The last type is the whole-house dehumidifier, which is usually placed in your loft and gently pushes dry air through your home, pushing out damp stale air. These are very cheap to run but can be expensive to install.
