Especially for city dwellers and in our modern climate, clean air quality is getting to be increasingly important. While air pollution is commonly associated with the outdoors, the air in our home can contain contaminants that can be equally, if not more toxic. Take, for instance, microscopic particles to allergens like pet dander and harmful gases emitted from common household products.

Below, we’ve rounded up the air purifiers worth investing in to upgrade your indoor air for a healthier, cleaner living environment.
