I have dust mite proof bedding, laminate flooring, wash the bedding at 60 degrees, etc. etc.. Ultimately they cannot be stopped from breeding, and g ass pollen cannot be removed from the environment.

Without my current drug load I am constantly coughing from the irritation caused by mucus, and quite often feel the need tp retch and throw up because it causes me to randomly gag.

Short of living in a sterile bubble, there is nothing filters could do to address that.
