We have two parrots, one of which produces a lot of feather dust. We have an open floor plan, and this filter cuts down the dust (feather and otherwise) in an area larger than the 815 sq ft it was rated for. We also have two dogs, and friends with allergies. Prior to owning this filter, our friends would have issues at our house, but if I run the filter on "turbo" a few hours before they come over, they are 100% comfortable. I also purchased an Austin Air Healthmate Plus, and I found the Rabbit Air a better fit for us. The Rabbit Air has air quality sensors that automatically adjust the speed as needed. When my dusty bird fluffs its feathers, within 10 seconds the Rabbit Air kicks into high speed. I have had one Rabbit Air for about 3 years, and just purchased another one for the bedroom.
My allergist recommended I change quite a few things about my bedroom -- allergen-proof cases for the mattress and pillows, HEPA filter/air purifier, take away the curtains, dust and vacuum religiously, keep the cat away from the bedroom, etc. This is the HEPA filter/purifier I chose and so far, I'm very happy with it. It has a nice noise for white sound, which helps sleep, and it seems to be doing the job with allergens in the air, since I am not waking up so allergic. Only downside: It has a blue light on the top that is kind of bright for a darkened bedroom when you're trying to sleep. We put a post-it note over the blue light at night, just stuck on one side so you can still adjust the fan speed but it covers the light, and that worked pretty well. There's still enough light for a nightlight, but at least it's not like a huge blue ambulance light in the bedroom with us.
I am very pleased with this air purifier. It is so quiet that you cannot tell it is running. I have it in my bedroom and I can breathe so much better since I am using this air purifier. I have a much better night's sleep and am amazed that I no longer have a stuffy nose in the morning. I recommend this to all sufferers of sinus problems and asthma.
