Simple and effective solution

No electricity needed which is a huge plus for my unfinished garage. Setup took seconds. Just wish the hanging hook was a bit sturdier, but overall a solid product.

Perfect for my damp basement

I was skeptical about how much water these could actually pull from the air, but after two weeks, the collection tray was half full. The musty smell in my basement has significantly decreased. Highly recommend for humid seasons.

Good but scent is faint

The dehumidifying aspect works great, but I was hoping for a stronger fresh scent to mask the old warehouse smell. It helps a little, but don't expect it to act like a strong air freshener.

Essential for summer humidity

Living in a coastal area, humidity is a constant battle. These boxes are a lifesaver for my closet. Clothes feel drier and fresher. Will definitely buy again next season.

Works well, but fills up fast

These do exactly what they promise. In my garage, they fill up quicker than expected during the rainy season, so be prepared to check them weekly. Great value for the price though.

No more mold worries

We had some minor mold issues in the corner of our storage room. After placing three of these boxes there, the dampness is gone and no new mold has appeared. Easy to hang and use.

5 FAQ

Q: Can these be used in a refrigerator to keep it dry?

A: While they absorb moisture, these units are designed for larger spaces like rooms and garages. We recommend specific small-scale absorbers for refrigerators to ensure food safety.

Q: Is the liquid inside dangerous if spilled?

A: The collected liquid is a saline solution. While non-toxic, it can be slippery and may irritate eyes. Please wipe up spills immediately and keep out of reach of children and pets.

Q: How do I know when the box is full and needs replacing?

A: The transparent window on the front of the box allows you to see the water level. Once the collected liquid reaches the indicated 'Full' line, it is time to dispose of the unit.

Q: Do these work in freezing temperatures?

A: The calcium chloride crystals may crystallize or slow down significantly in freezing temperatures. For best results, use in environments above 40°F (4°C).

Q: Can I refill the boxes once the crystals dissolve?

A: No, these are single-use units. Once the crystals have fully dissolved and the water is collected, the entire box should be disposed of according to local regulations.
