The Airfree Iris 150 removes microorganisms, allergens, and bacteria from the air in your home. This reduces complaints such as coughing and a stuffy nose. The air purifier sucks in air and heats it to 200°C, which sterilizes it. Next, the clean air is cooled and blown back into the room. The Airfree Iris 150 is silent, which makes it suitable for use in the bedroom. The device is maintenance free because it doesn't have filters or disks that you need to replace. You can adjust the color of the light on the top of the air purifier as desired. If you can't make up your mind, switch on 'random mode' so that the different colors alternate.
