You can connect the Philips AC3259/10 to the app on your smartphone. This means you'll always be up to date on the air quality in your home, even if you're not at home yourself. Via the app you can turn on the air purifier, check the lifespan of the filter, or change the fan speed, for example. The air purifier has 3 automatic purification settings: a general mode, an extra sensitive allergen mode, and an extra powerful bacteria and virus mode. The allergen mode removes common allergens in the air. Is the device registering a change in air quality? It'll start working harder right away to remove allergens from the air. In addition, there are 5 manual settings as well: from a very powerful turbo mode to an extra silent mode for your bedroom. Want to quickly check the air quality in your room? No problem. The device has 3 indicator lights: blue (good), purple (medium) and red (poor).
