Is Apatite a safe material to be used on air purifier filters?
I learned that the Sharp air purifiers' HEPA filters have an Apatite component to it that apparently provides antibacterial properties to protect the filters from microbial accumulation. Is Apatite a relatively "safe" material to use for an air filter, i.e. is it safe for the resident who is breathing air that comes through the filter? Apatite (a very general term) is usually made up of phosphorus and calcium, but some variants (ie. arsenates like mimemite) may contain arsenic. Could this be a health issue for users? Would the filters use arsenic-based variants in the first place, or are other forms more prevalent and likely to be used in medical/industrial applications?
Apatite is a group name for hexagonal or pseudohexagonal monoclinic arsenates, phosphates and vanadates.
In general use 'apatite' is often used in particular for the Calcium Phosphate minerals, Fluorapatite, Chlorapatite and Hydroxylapatite.
There is no specific data on health dangers or toxicity for this mineral.
It is unlikely that an arsenate would be used in this application. The other forms are quite prevalent and more of these are actually mined as ore.
