A word for air that comes from your nose rather than your mouth?

I am looking for a concise, non-clumsy way of referring to breath that comes from one's nose rather than from one's mouth. A single-word would be nice.

I've done a Google search to no avail and reviewed Is There a Term for Letting Out an Exasperated Sigh Through the Nose but it's not what I'm looking for. Huff and humph were some of the good answers there but it wouldn't quite work in the sentence I am thinking of.

"Bad breath can be mitigated by not breathing through your mouth. Air that comes from your nose rather than your mouth is less smelly.

[One word for the all bold words would be beautifully concise if it exists!]

One post suggested suspirate which doesn't appear to be a word but that led me to suspire (verb) and suspiration (noun) which are. Unfortunately, according to a review of the OED entries these mean sigh and don't denote a sigh through the nose.

A compound word or phrase would be acceptable, but preferably something shorter than the phrase I came up with!

Solution 1:

You can make the sentence in the bold concise by removing 'that comes'.

Also, you can remove the words 'rather than your mouth' as the comparison is obvious after reading the first sentence. So, the sentence could be made concise as follows.

Bad breath can be mitigated by not breathing through your mouth. Air from your nose is less smelly.
