Is DE Toxic?

DE (Diatomaceous Earth) is a powder, derived from fossilized mineral deposits, which are mined from the ground and then processed.

There are two types of DE pool grade and food grade.

Food grade DE is low in crystalline silica and is considered safe for humans.

Pool grade DE is toxic and should only be used in filtration.  If inhaled it can cause irritation to your nose and lungs.
