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?

Thanks, UK Export. So, from my understanding, most of the apatite used in industrial/consumer applications is manufactured or refined (to remove impurities like As), is that correct? Which are some of the companies who sell synthesized/refined apatite?

What about the mined apatite? Are they used for anything other than for decorative/esthetic gemstones? Thanks again.

If i chopped up a pumice stone and put them in my canister filter would it be a good filter media and if i did would it put out anything into the water to change the PH of the water or increase the calcium and stuff like that

We have horrible lime and calcium build up – very hard water. We want an entire water softner/filtration system.

Bottled water or attachments for the sink is not what I am talking about, it needs to be for laundry, showers, drinking, cooking, etc.

Please help!
