Best Moisture Absorber For A Storage Unit Buying Guide

You can’t just buy any random absorber you find on the market. Some absorbers are better than others. Use these factors to make the right choice:

1). Location

Where is the absorber going to work? Certain ingredients work better in some places than others. For instance, you cannot use calcium chloride-based absorbers inside packages because calcium chloride requires high levels of sustained moisture.

You are better off putting the product in a shipping container. Clay desiccants, on the other hand, perform efficiently inside packages.

2). Toxins

When calcium chloride absorbs moisture, it becomes a liquid gel. That gel is corrosive. Clay desiccants remain dry. Because calcium chloride products present a leaking hazard, you shouldn’t use products that have this substance inside packages.

3) Packaging

Products that use calcium chloride require a lot of packaging material because the manufacturers don’t want them to leak. Clay desiccants don’t have this problem. You don’t have to keep them in several layers. In fact, some of them use environmentally friendly Kraft paper.

Moisture absorber can eradicate excess moister from the storage unit, but it can not control cockroach infestation. Cockroaches and spiders can do a lot of harm to the product of the storage unit. To keep the cockroach and other insects away, you should use a bug bomb for storage unit.
