Thank you for your inquiry.
We are of course well aware of respiratory irritants causing respiratory symptoms such as in patients with chronic rhinitis (especially chronic nonallergic rhinitis) and asthma. There are many well-documented examples of this phenomenon. However, I am unaware of, nor could I find with a literature search, any well-documented case of cardiac symptoms due to exposure to such irritants. In addition, I am not aware of nor could I find any study on the use of nasal filters to protect against such exposure.
Thank you again for your inquiry and I am sorry that I could not give you more practical useful information in this regard.
