Perfect for bedrooms, this machine is supereasy to set up and use. The light on the front changes colour to indicate current air quality, whether good, moderate or polluted. It will turn red when it’s time to change the filter, which is recommended around every six months. The Scandi-style pre-filters are the real star here, giving you a choice of exterior cover colour, from the dark grey (included) to light grey, pink, green or blue. These don’t just look pretty, but they catch larger particles and extend the life of the primary filter inside.
