I'm allergic against cats, but I live with one (I know, I know). Because of this, I use an air purifier and decided to upgrade our AC filter. It's only been 4 days but I can already feel the difference in our air. I still take allergy pills every day, but by lunchtime I no longer have a stuffy nose. I compared prices online at nearby physical stores (Walmart and Target) and they were almost the same.
