The cat allergy question has been asked before, and I do have the standard itchy eyes, stuffed nose, sneezing, etc. However, I'd specifically like suggestions regarding cat-induced asthma. Mine is severe enough that, although I haven't done it for years, spending 24 hours in a house with cats has put me in the emergency room and on a nebulizer. One person in that previous thread mentioned that Claritin helped. Has anyone else had experience with something that helped not just their cat allergies but the cat-induced asthma as well?

With some products, the off-brand is as good as any other brand, sometimes even coming off the same production lines in the same factories. With other products, there is a quality difference between brands. How about for replacement HEPA filters for a Kenmore air cleaner? (And, as a bonus, should I believe the warning against washing and reusing the charcoal pre-filters?) [more inside]
