After looking at 15 options, I put together this collection of air purifiers that actually work in big spaces and for people dealing with allergies. The key is matching the clean air delivery rate to your room size and checking that the filter captures pet dander, pollen, and dust, since not every unit handles all three well. Prices here run from about $30 to $260, so there is something for a tight budget or a larger investment. Whether you have a shedding dog or just wake up sneezing, these picks should help you breathe easier at home.
