It's been reported that the home interior can actually be five times more polluted than its exterior. More than just a modern cooling fan with no blades, this new addition Dyson Pure Cool Link Tower ($500) also includes an air purifier that monitors and removes up to 99.97 percent of the bad stuff like allergens, pollutants, odor, and pet dander. The filter needs replaced every six months. Setup is super easy — just click a few pieces together and make sure you set up the app.
