Air Purifier/Filter for allergies?

Take a look at the information at http://www.allergy-relief-air-purifier.com/green-air-filters.html to learn about the different types of air cleaners and their proper usage. I would suggest that in your case, you want to purchase a HEPA type air purifier, like the Sun Pure SP-20C at http://www.allergy-relief-air-purifier.com/portable-air-purifiers.html and make sure to keep the cat out of the room that you set it up in. That way you have a refuge to go to when the symptoms get overwhelming. I hope this helps.
