Asked by bowhunt November 23, 2020

First off, the cubic volume of your storage area is 392 cubic feet. Each individual canister is designed to cover a maximum of 3 cubic feet. The best option would be to use the smaller canister in each individual box that you are storing in the unit. If you are wanting to use silica gel to cover the entire volume of the storage unit you would need 5,227 grams(or 11.52 lbs), so I would suggest going with a higher volume canister to get the appropriate coverage for your area.

Asked by Guill February 10, 2020

Can this be used to help prevent moisture and mold in an outside BBQ?

Asked by JK September 22, 2019

Will moisture be absorbed by this better than ice melt?

Asked by Kay April 7, 2019

Great question. I don't think it will directly protect it by preferentially attracting the water to itself rather than the CaCl2. I think I would try storing your ice melt wrapped as effectively as you can, and then put it into a container with a small excess volume and protect that volume with either silica gel or more ice melt with a little collection bin, like the ones available at the dollar store. This way, you can try to keep the small volume of air in the container very dry before any significant moisture gets past the bag or plastic bucket that the ice melt is in. Does that make sense?

could you use it in refrigerator?

Asked by julia February 6, 2019

Yes thought for this amount of Silica Gel (40 grams) it would best be utilized in a space of 3 cubic feet or less.

Would a couple of these placed inside a small 25' travel trailer help with the moisture after win...

Asked by JHM October 14, 2018

Not really. You would have to make sure the trailer was air tight so the outside humidity would not be able to enter the trailer. You also need to know the cubic feet of the inside of the trailer. The is a specified amount of silica gel recommended for the amount of space it would be used in.

What are the dimensions?

Asked by Janwit October 5, 2018

This product has the following dimensions: 4 depth x 2 height x .5 width in inches.

watch out for escaping silica gel balls
Received 6 of these as ordered. I purchased them for storage boxes for ammo. I placed 4 of them in different boxes. the next day I had an item that I needed drying out so I put it in a zip lock bag opened the wrapper on a gel pack and as I was placing it in the bag silica gel ball went every where. Packs are not sealed and there are too many ball in container to reinstall them, one half of case will not hold all of the balls. After getting what ball I could into the case I then went and checked the other cases one of them had come open and ball all over storage box. Same result here all the ball would not fit in the top or bottom of the pack, so I lost about another third of the balls from this pack. Since the packs must be heated to 280 degrees f. I had some alum. heat duct tape that I sealed all the packs with. If you buy these make sure you have some heat duct tape handy to seal them with or you will have silica gel ball every where.

While it appears that it does its job, the casing comes apart very easily and the silica beads spill all over the place. There is no need for it to be opened at all, so I am not sure why it is not just fully enclosed. I put a binder clip on it to keep it from opening which solved the issue.
