I've just had results back from a blood test that I have a strong allergy to dust and cats. I have three cats
. I'm taking all the measures I can to lessen the problem (got rid of feather sofa for a foam one, hoovering daily, cats not allowed in bedrooms, bug spray for dust mites etc) but would love an air purifier downstairs. It's all open plan down there so one for a larger room. Prob about 50 sq ft? I also have hayfever, so one that deals with dust mites, cat allergens and pollen would be great.
