The Best Moisture Absorbers To Prevent Mold, Mildew and Allergens From Taking Over Your Home

Moisture absorbers can be helpful when it comes to preventing mildew and mold from growing in damp areas like bathrooms, basements, closets and beyond. Sure, you could just as easily use a dehumidifier to remove moisture from the air. However, dehumidifiers are significantly more expensive and work best in spaces with a lot of airflow, whereas moisture absorbers work best in smaller confined areas. Check our list of the best dehumidifiers if you’re looking to invest in a model that fits into your lifestyle and home.

That said, when trying to remove moisture from an enclosed, smaller area or looking to save a few bucks, moisture absorbers are the way to go. If you’re having a difficult time figuring out the best moisture absorbers to fix your particular situation, we’re here to help with a list of top-rated options. But before we begin, it’s probably best to start by going over the moisture absorbers most commonly used.

Silica Gel

Silica gel, made of sodium silicate, comes in bead or granular form and attracts and removes moisture from the air. Most often sold in small packets or devices, silica gel works well in room temperature conditions but can be quite expensive if being used in larger areas like basements.

Calcium Chloride

Calcium chloride is an amazing choice from high humidity areas like kitchens, basements, closets and more. Often sold in a bucket, it has the ability to attract several times its own weight in water and will dissolve into brine if the air is humidity and temperature is high enough.

Clay

Clay, used as a moisture desiccant, is a great cheap alternative to silica gel, calcium chloride and other methods. However, clay likely isn’t the best for heavily humid areas since it’s not as effective at preventing mold and mildew in those conditions.

Activated Charcoal

Activated charcoal can also be used as a more eco-friendly option for reducing moisture in food, vitamins, medicines and more.

Now that we’ve laid out the basics, it’s time to dive into the best moisture absorbers to make your home a healthier and happier place to live.
