I think the phrase you want is,

"safe to breathe through"

rather than, "safe to breath true"

I'll leave it as an exercise, for the interested reader, to look up those words in a dictionary.

https://en.wiktionary.org/wiki/through


The part I am wondering about is the adapter. I mean, where is the adapter that adapts the funny shape of that Brita(r) brand water filter, to something you can wear on your face?

Maybe you have not built that part yet.

Anyway, my main concern is the question of how fast air can move through that water filter cartridge, and is that fast enough for safe breathing?

So, in the event you build a mask to fit this filter, I suggest you test it out with friend nearby. The reason why you want a friend nearby, is because you are going to instruct your friend to remove the mask from your face, in the event you loose consciousness.


The reason why you have to do it that way, is that you do black out from lack of oxygen, you will not be able to take the mask off yourself.

By the way, if you are looking for a contrivance to filter bad air, for to make it more breathable, there is something called a, "respirator" or "respirator mask" or similar, sold in hardware stores. It will usually be in the same aisle with the gloves, and safety glasses, and hard hats, and other PPE (personal protective equipment).

https://en.wikipedia.org/wiki/Respirator

https://en.wikipedia.org/wiki/Personal_protective_...

Wikipedia also has an article for "Hazmat suit"

https://en.wikipedia.org/wiki/Hazmat_suit

and also "gas mask"

https://en.wikipedia.org/wiki/Gas_mask

Again, I will leave it as exercise for the interested reader, to figure out how those topics are similar or different.

As another BTW, if you want a way to test a activated carbon air filter, to test if it is working, there are a number of easy to find, substances that produce a strong, recognizable smell, e.g. garlic, vinegar, menthol, that is also easily adsorbed onto activated carbon.

I have seen a list of these substances, or odors of the same, in a PDF titled, "Activated Carbon Capacity Index Chart".

https://duckduckgo.com/?q=activated+carbon+capacit...

It is not really a chart. It is more like a list, and I am not sure of the sources for it, or how reliable it is. It was probably written by someone who sells activated carbon. You will recognize this list by its vague and colorful entries, like "cheese", "body odors", "gasoline", next to more chemical sounding names like, "butyl acetate" and "dichloroethane"

If it is for fun then no problem, if it is for actual use as protection don't do it.
A gas mask needs a filter that is fully sealed and won't let any unfiltered air through.
Water filters are designed to work under pressure while a filter for breathing maks is designed to allow a very flow of air.
After all, you neither want to struggle to get air, nor risk getting unfiltered air.

It is quite easy to make your carbon filters from scratch.
Wouldn't recommend them to test tear gas or chlorine but for what you encounter in your workshop it will be fine.
