I use air purifiers, I have a small HEPA in my bedroom, and a larger high capacity purifier for the rest of the house, but its only rated to capture 99%.
I have also installed a HEPA filter in my car.
I know they help me, especially during pollen season, and again they help in the fall during harvest\combine season; the only 2 times of the year that I experience asthma symptoms.
Also, you may get a laugh out of this, but when I'm tent camping, which I do a lot of, I sleep wearing a HEPA half-mask, difference is amazing, I never wake up runny nosed or stuffed up or wheezy when I'm sleeping in the great outdoors.
