I was looking to get something that I could use to put in my closet to keep the humidity down. So while I was looking to get some capsules I came across the silica here http://www.airtites.com/silica_gel_....VIZe57l0y00

I wasn't sure what the difference between the 750g container and the 900g container. Other than what they say in the description and charge for the price I don't know much about them. Does anyone have some experience with using them or have any recommendations for what I could use?

I was to lazy to move all of the junk I have to get a measurement of the closet. I just figure I cant go wrong with to much.

I have ordered the smaller packs from them and they work well.

Have you thought of using an electric dehumidifier? The size of your closet will matter as to how much desiccant you will need.

I agree.
A closet is a rather large space to control humidity using only a desiccant.

I've got about 6 cu ft to condition and I use seven Silica Desiccant - 40 gram units.
Sort of an overkill but better than not enough.

I do have a dehumidifier I use but its not located in my closet. Since I have central air heating/cooling system for my house the dehumidifer I use should help with the rest of the rooms inculding the closet where I keep the coins.

I was thinking that if I put some dessicant directly on top of the box I store my coins in, it would help keep that area more dry preventing moisture from getting in. I keep my silver coins in ziplock bags with the addition of smaller deccicant packs in the bags and in the box itself around everything. I feel that should work well enough...I hope.

I just dont understand the difference between the 750g and 900g dessicants. Why does the 900g cost less than the 750g? Would one work better than the other for what I want to do?

By my reading, the difference is in the container, and how they are reactivated. The 750g unit is steel, the 900g unit is either cardboard or plastic (it doesn't say, but presumably it's not metal). The 750g unit is designed to go straight in the oven to re-dehydrate, no disassembly required; you need to disassemble, dry and reassemble the 900g unit.

So they are charging more for the convenience factor instead of how well it works. Anyone have some thoughts if I would just be wasting my money?

If they work then you will need to recharge them. That being said, if you do not need to recharge them, then you do not need them.

Remember that time is money. I would much rather cook the one in the can.

If you are running a dehumidifier, I would first get a hygrometer and see what the humidity level is in the house or in the closet. If you have a reading that is satisfactory, you wouldn't need to do anything else.

Thanks everyone for your thoughts and input. Jbuck's thinking that time is money influenced me to get the metal one so I can spend more time looking at my money.

As already noted first get a Hygrometer. Walmart has a variety of them. Some come with temperature, humidity and even time. Large variety of them available. If you house reads less than 30%, not much to worry about. Acquiring a separate dehumidifier may well be a waste of money. However, a place called Menards and Home Depot usually have a variety of small ones that use Humidity absorbing materials. Main problem is they have to be maintained. I have one large electric dehumidifier for my entire house and it works great.

My son works in a furniture store here they sometimes assemble furniture. He gets a large pack of silica gel in every box. When I found this out I asked him to save it for me. You might be able to get a local store to do the same for you (try a Mom and Pop).

I have a wire basket in my safe into which I throw the silica packets I get from work (out of server and other electronics boxes), from shopping (shoe boxes and such). I've accumulated a basketful over the last couple of years.

Not sure how effective it is.

Can these packets be safely cooked to dehydrate?

I would say no because of the packaging the silica is in. I would be afraid of it melting or worse catch fire. Those are more like a one-time use then throw away. What I don't like about those is you have no way of knowing when they go bad and I wouldn't want one full of moisture near my coins. A basket full sounds like a lot so I think you are safe for now but who knows how long they will be good for.

Yes, you can "cook" the little packets to re-dry them. So long as the oven is not too much above 100 deg C, you shouldn't have to worry about them catching fire. Nor will silica gel "melt". Only thing wrong with using these disposable gel packets is that you can't tell whether they're wet or dry, so you (a) don't know when they need re-drying and (b) while re-drying them you can't tell when they are "done". Though a couple of hours should be adequate.

A fully "wet" piece of silica is no threat to the coins, in and of itself; it's not letting go of that water unless it's heated. However, it's not doing it's job anymore; the next time the box is opened and humid air can get in,
