Not only does decluttering help to make the space more aesthetically pleasing but it also helps create a safer environment.

We’ve all been there—you’re walking by a bookshelf, and when the light hits just right, you see a gray film sitting on the surface. Or, you’re relaxing in the living room when a ray of sunlight streams through the window, illuminating a vortex of particles floating in your air. Every home in the world constantly battles against this nemesis: dust. It isn't just an eyesore, though. It’s harmful to your health! 

A high amount of dust signals an issue in the home that’s not always on our radars: poor indoor air quality. That sun shining through the window reveals those floating particles in the moment, but they’re invisible the rest of the time we’re in our homes. Not to mention, those are only a large collection of stuck-together particles visible to the naked eye. There are countless others too small to be seen.

Dust is essentially a combination of particles from indoor and outdoor sources that have built up long enough to become a visible layer of grime. Some common culprits in dust include skin cells, pollen, dirt, pet dander, insect parts, dust mites and their droppings, mold spores, bacteria, mycotoxins, and whatever else is floating around the home.
