Best use in homes that require multiple rooms of DampRid. I purchase these a few times are year along with the smaller cups. I pour this in in lieu of the cups. If you have a larger home that has humid/wet weather -- these are a must have. I have used DampRid for roughly 15 years and never have mildew issues anymore. It works!

I like that this comes in one large easy to open and close container instead of needing to buy several bags that never close all the way once you open them. I live in Florida and have Damp Rid containers hidden all over my house. I have to refill them often and this is the best way to store the refills.

Been using it for years & as a private housekeeper, I have introduced many homeowners to DampRid- They had never heard of it & now they use it continuously in their homes. They are amazed at the good it does- no mould, mildew, no condensation dripping on inside window glass & rotting wood sills. This stuff keeps you healthy from deadly spores of dangerous fungus's & save you big money on home repairs, too. Good stuff, folks- I really swear by it. Especially with children in the house, you do not want deadly mould growing in your home. It compromises the immune system & can cause a simple cold or flu to escalate into a real threat. And Athsma sufferers& this stuff can save your life!!
