Danny Seo's Do Just One Thing

Sept. 27: Did you know the air quality inside your home can be worse than it is outdoors? It's because homes are designed to be very energy-efficient and airtight, which means allergens, dust and toxins can build up inside. To improve air quality, try to ventilate whenever possible by opening windows and turning vents on in the kitchen and bathrooms. Clean with a vacuum that has a filter that absorbs dust and other allergens instead of allowing them to recirculate in your home. And invest in a steam mop; not only does it clean floors really well, but the hot water disinfects, too.
