How to Choose a Large Dehumidifier

Dehumidifiers reduce moisture levels, protecting walls and floors from mildew and mold and keeping allergy sufferers and infants and toddlers healthy. They can even prevent damage caused by condensation on windows and doors. To ensure you get the right dehumidifier for your home, it’s important to consider how much square footage needs to be dehumidified and what other factors are at play.

You should also know whether you’re looking for a desiccant model, which operates best at lower temperatures, or a compressor dehumidifier, which is suitable year-round. Finally, you should decide on the daily capacity needed, which affects how often you’ll need to empty the water bucket or add a filter.

If you have a large space that’s prone to high humidity, you may need to choose a larger unit. You should also test the air humidity with a hygrometer, taking note of the visual signs, such as spots of mildew and damp surfaces.

The best large dehumidifier should be easy to use, with an intuitive interface and simple maintenance procedures. You should be able to see the water tank filling up on a digital display and easily remove it from the unit with a handle, which makes emptying it a breeze.
