A company called Dyson has made an air cleaner for the home. The new air purifier is called the Pure Cool Link. It catches up to 99.95 per cent of pollutants in the home. Pollutants are the things like dust, pollen and smoke. The device needs one hour to clean the air in a room. It checks the air quality to keep it at safe levels. This is great for people with allergies or asthma. The device is linked to an app, so users can control it from anywhere in the world.

Pollution is not just a danger outside the home. James Dyson, the founder of the Dyson company, said: "We think it is polluted outside of our homes, but the air inside can be far worse." Modern homes do not let air or noise in or out. This means the pollutants we create inside the home are trapped. They can be up to five times the levels they are outside the home. The air purifiers will cost between $500 and $650.
