Hi all... Just to give you a little ease when using and storing... don't worry too much about double dipping, the DE acts like a sponge yes but once it absorbs it doesn't release it. It also continues to absorb until that particle can not hold anymore. So IMO you shouldn't have to toss and replace bc you double it, it absorbs whatever is in the air so when ever you open the container it is taking in something. I would say to make it easier and purchase a couple large glass or plastic containers with lock n lock lids or screw lids, and remove your individual amounts by a small glass cup. When I take mine to work I put it in a sandwich baggy and mix in Panna water when I am ready to take it.... Just wanted to help you not spend extra $ and take away xtra worries as well as making it easier to use and store. Xoxo Meg280 |
