1 gram of silica gel/desiccant = 1 litre of space
Just imagine for your container, how many litres of water would it take to fill it up? If you think 1 litre, then our 1 gram size would be sufficient. If you think maybe 5 litres, then you would need the 5 gram size. As simple as that.
Open the main seal to activate the silica gels/desiccants, place them directly into the space that you would like to dehumidify. That is it!
Keep camera equipment and other electronics dry.
A few packs in your camera bag and in your electronic storage compartment will preserve your gear.
Place with your photos and albums.
Keep silica gel packs where ever you store physical copies of your photos and albums to prevent damage due to mold and discoloration.
