One-touch clean air The Blueair Blue 3410 Air Purifier is designed to work in medium-sized rooms, where it can filter the air up to 5 times an hour. All it takes is a single touch of a button and the purifier adjusts the fan speed automatically based on real-time air conditions. Multi-stage filtration The brunt of the filtration is taken care of by the HEPASilent filter. It removes dust, pollen, mould, and other nasty pollutants. But the first layer of protection is the outside fabric cover, which acts as a pre-filter to catch large particles. It can be easily removed and washed, or you can change it for a different colour to change the look. There's also a particle + carbon filter that removes odours from pets, smoking or cooking. All three filters combined remove more than 99% of particles from the air. Smart design The Blue 3410 has a 360-degree intake, which means there is no wrong way to place it in your room. And with its minimalist design, it will fit right in. There is an LED light that changes colour depending on the air quality. So if you want to get rid of pollutants quickly before you go to bed, you can set the speed setting yourself.
