breathe easy

摘要

THE AVERAGE PERSON TAKES AROUND 20,000 breaths per day. The Dyson Pure Humidify+Cool aims to ensure that each one contains the right amount of moisture and as little yucky stuff as possible. This device relies on three internal systems, each with its own role to play in keeping air refreshing and squeaky-clean. Aturbine pushes air into the three-foot-tall device's oval-shaped head, which blows a focused gust out of the front, the back, or both as it oscillates, A "breeze mode" mimics natural wind. Fan-bound air flows in through a grate, and then a HEPA filter pulls out allergens as small as 0.3 microns, like pollen or mold. Smelly molecules that make it through get stuck on a grid of activated carbon. As water travels from a tank in the base, UV light kills almost all bacteria, From there, H_2O passes through a mesh (below) that turns it into a mist whose particles are too small to carry leftover baddies.
