Is the carbon in water filters gluten-free?

[Pepper88]

This sounds so ridiculous, but I'm wondering if anyone knows about the gluten status of carbon water filters. I read that "activated carbon is carbon produced from carbonaceous source materials such as bamboo, coconut husk, willow peat, wood, coir, lignite, coal, and petroleum pitch." Is there anything else it could be made of? We're looking to install a under the sink system but most companies don't state what material the carbon is derived from.

Although I'm 95% sure its fine, I've heard of people with coconut allergies get reactions from water filters (such an awful scenario). I'm wanting to get some reassurance before buying and installing the whole thing!

The coconut is different.  If I remember it is still in its coconut fiber/huskform.  
 

I never worry about a water filter.  If they burn the heck out of something to make it into carbon- there isn’t any protein in there.

Thanks for the reassurance Kareng. That makes sense.

When I am in misery due to a celiac reaction, I try to figure out what is harming me.  So much so that I started to think about the binder for the charcoal filtration in my water system. Verdict: who knows!?  But here is some info I found on a website:

What is the best binder for charcoal briquettes?  Starch is the most common binder though it is usually expensive. It doesn't have to be an food grade. In general, about 4-8% of starch is needed to make the briquettes. Starch sources can be corn starch, wheat starch, maize flour, wheat flour, rice flour, cassava flour, potato starch, etc.
