Review: Excellent Moisture Control! - I recently purchased the Dry & Dry (1 Gallon) Premium Silica Gel, and I am thoroughly impressed with its performance! This product has exceeded my expectations in every way. Firstly, the packaging is fantastic. The gallon-sized container is sturdy, easy to open, and reseals perfectly to keep the silica gel fresh and effective. The included scooping tool is a nice touch, making it easy to dispense the right amount. As for the product itself, the silica gel beads are high quality and highly effective at absorbing moisture. I use them in various places around my home, including my closets, storage bins, and even my camera bag. Since I started using Dry & Dry, I've noticed a significant reduction in humidity and no signs of mold or mildew. What I love most is the color-changing indicator beads. They turn from orange to dark green when it's time to recharge the silica gel, so there's no guessing involved. This feature is incredibly convenient and ensures that the product is always working at its best. Overall, I highly recommend the Dry & Dry Premium Silica Gel. It's an excellent investment for anyone looking to protect their belongings from moisture damage. The large quantity, effectiveness, and thoughtful design make it a top-notch product. I'll definitely be purchasing this again!
Review: Works well - Great Product. Exactly as expected. The color change is an accurate indicator for you to dehydrate the beads. I have recharged numerous times with no loos of effectiveness.

## Questions & Answers

**Q: Besides color, what is the difference between the blue and orange beads?**
A: Type of dye used for color is the only difference between blue and orange beads.  Performance wise, they are the same.
Silica gel beads are white in nature.  However, you can't tell when they are saturated with moisture with white beads. Therefore, cobalt chloride is added to serve as an indicator (blue to pink).  Cobalt chloride is known as carcinogen.  European markets prohibited the use of blue silica gel beads in 1998.  Therefore, orange indicating beads were made to conform to the European Union requirements.   Thank you.

**Q: Would these work in an outside, enclosed storage shed?**
A: All silica gel beads and packets work in air-tight seal container. If they are open to air, they are constantly absorbing moisture in open air and become saturated right away. 
Please, keep them tight seal as much as possible. 
Information below lets you estimate how many gram of silica gel is needed at a given volume of your container. 
This is general estimate when used in an air-tight sealed container. The amount of silica gel needed will depend on several factors: 
1. Chemical properties of the product that will be used: 
2. Volume of the container 
3. Conditions and physical properties of the container 

Container volume – packet size 
120 cubic inch - 1 gram 
240 cubic inch - 2 gram 
360 cubic inch - 3 gram 
600 cubic inch - 5 gram 
2 cubic feet - 30 gram 
4 cubic feet - 60 gram 
8 cubic feet - 120 gram 
64 cubic feet - 960 gram 

If you intend to use silica gel beads for storage shed, you'll notice that you'll need larger quantity and also they will change color faster.  Silica gel beads and packets are ideal for you to use with air-tight containers to store your items. 
For your shed, we would recommend using the dehumidifier or moisture absorbers (calcium chloride).

Silica gel beads are for an air-tight sealed environment. They continue to absorb moisture until they become fully saturated. They can bring the humidity level down to <10%.
Moisture absorber contains mineral salt named calcium chloride. These are ideal for small enclosed space like garage, basement, attic, closet, and etc..

Calcium chloride crystals absorb excess moisture in the air and brings the humidity level of about 50% which is an ideal and safe level. These crystals will slow down when the humidity level drops below 60% and will restart again when necessary. This is cost efficient, because the product will works when it's needed and not when it does not have to. 
However, calcium chloride is not reusable. 

Below are the ASINs for moisture abosrbers and hanging moisture absorbers.
B07JHVN4T7 and B07JL32YTB .

Thank you.

**Q: does this contain enough volume to fully cover a 16in diameter bowl thats 5in deep? thanks**
A: Cover? or fill?
You would need 4.35 gallons or 1.006Cu,in.to fill an area with a diameter of 16 inches and 5 inches deep

**Q: Is this safe to use in a desiccant drier in an automotive paint shop?**
A: Yes, many of our customers use our beads for air dryer for painting. Thank you.
